Final answer:

The number 35 in sulfur-35 represents the mass number of the isotope, which is the total number of protons and neutrons in the nucleus. Sulfur, with atomic number 16, has 19 neutrons in this isotope.

Explanation:

The number 35 in the isotope sulfur-35 or S-35 signifies the mass number of the isotope. The mass number is the sum of the number of protons and neutrons in an atom's nucleus. Sulfur's atomic number is 16, meaning it has 16 protons. To find the number of neutrons in sulfur-35, we subtract the atomic number from the mass number, yielding 35 - 16 = 19 neutrons. Sulfur has several isotopes, including sulfur-32, sulfur-33, sulfur-34, and sulfur-36, with varying neutron numbers and natural abundances. Sulfur-35 is a less common isotope and is not found in significant abundance.

Answer:

Electric energy conservation which converts into heat and light

Explanation:

The transformation of energy  from one form energy into another form, and throughout this conversion, the energy that we give to a device will comes out. However, the energy that is given may or may not coming out in the required form.

For example, we plug in a lump means we give an electrical energy into a lamp and the lamp produces light,  but we also get heat energy from the lamp(it is the  form of energy which is undesirable coming from a lamp).

Correct option is B

B.The glass opposite of the negative electrode started to glow.

In his experiment, tubes were two electric plates, producing a positive anode and a negative cathode, which he expected that it would deflect the rays. As he supposed, the rays were deflected by the electric charge, proving beyond doubt that the rays were made up of charged particles bearing a negative charge.

Boron is a chemical element in the periodic table with symbol B and has atomic number 5.

Boron has two naturally occurring isotopes Boron-10 and Boron-11. The average atomic mass of these are calculated as

The answer is b

Explanation:

I just recently did the test

The bond dipole moment determines the molecular polarity of diatomic molecules. Homonuclear diatomic molecules have no difference in electronegativity and therefore have a dipole moment of zero. Heteronuclear molecules have a small dipole moment, while molecules with a larger electronegativity difference have a larger dipole moment.

For diatomic molecules, there is only one bond, so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as Br2 and N₂ have no difference in electronegativity, so their dipole moment is zero. For heteronuclear molecules such as CO, there is a small dipole moment. For HF, there is a larger dipole moment because there is a larger difference in electronegativity.

Wind is primarily created by the process of convection, which is the macroscopic movement of air due to differences in temperature. Warm air rises and cool air sinks, leading to the movement of air known as wind. Conduction and radiation, although also types of heat transfer, do not predominantly contribute to the formation of wind.

Wind is primarily caused by convection, which is one of the three types of heat transfer, including conduction and radiation. In the context of our atmosphere, convection is the movement of layers of air due to differences in temperature.

Essentially, warm air, being lighter, rises and cool air, being heavier, sinks. This continuous cycle of heating, rising, cooling and falling gives rise to winds, in an effort to equalize global temperatures. An example of this heat transfer can be seen in weather systems. The movement of air mass creating winds is a product of such convection currents.

It's important to differentiate between this and the other types of heat transfer. For instance, conduction is heat transfer through direct contact of two objects, while radiation is heat transfer through electromagnetic waves, neither of which primarily contributes to the creation of wind.

Moving left to right across a period on the periodic table, atomic radius decreases due to a stronger nuclear pull on electrons, while atomic mass increases because of the addition of protons and neutrons.

Two key factors affecting these trends include the increase of the atomic number (Z) and the effective nuclear charge felt by valence electrons. As a result, several trends can be observed：

Reactivity does not uniformly increase; it typically decreases for metals and increases for nonmetals.

Atomic radius decreases due to the increasing effective nuclear charge.

Atomic mass increases because elements have more protons, neutrons, and electrons.

Valence electrons generally increase, not decrease, as we add more electrons to fill the outermost shell.

When considering the provided trends, atomic radius decreasing and atomic mass increasing are trends that accurately describe what happens when moving left to right across a period. The atomic radius decreases mainly because a greater nuclear charge exerts a stronger pull on the electrons, drawing them closer to the nucleus. As the atomic mass increases, this is because protons and neutrons are being added to the nucleus as you move across the period. While reactivity varies depending on the type of elements (metals or nonmetals), we know that valence electrons actually increase as we move across a period, which is contrary to one of the listed answer choices.

The products of the oxidation of glucose with an excess of oxygen are carbon dioxide and water.

A combustion reaction can be defined as a reaction that produces heat and occurs at an elevated temperature. It is an exothermic reaction, a redox chemical reaction that occurs between a fuel (hydrocarbon) and oxygen in the atmosphere.

Oxygen is an essential component for combustion because combustion cannot take place in the absence of oxygen. Complete combustion occurs when hydrocarbon burns fully to form water, carbon dioxide, and heat.

The burning of wood is also combustion where the carbon present in wood reacts with oxygen gas in the air to liberate heat and form gaseous products.

During the combustion of glucose reacts with an excess of oxygen gas to give six molecules of carbon dioxide and six molecules of water.

Two properties of substances containing ionic bonds are:

These properties arise from the strong electrostatic forces that hold the oppositely charged ions together, creating ionic compounds with characteristic behaviors when in different states.

Answer : The correct option is, The solvent molecules surround the solute particles.

Explanation :

Dissolving process : It is defined as the process in which solute particles interact with solvent molecules.

When solute particles comes in contact with the solvent particles, firstly the solute particles break down into ions and this result in the Lattice energy of the solute particles.

When solute particles break down, it gets surrounded with the solvent particles and it results in the Hydration enthalpy of the particles.

Further Explanation:

Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals. Covalent bonds involve two atoms that share electrons and reach a more stable electron configuration

Ionic compounds are those compounds formed from the ions of the species. Ions are the species that are formed due to the loss or gain of electrons. Cation forms by the loss of electrons and anion forms by the gain of electrons in a neutral atom. The ionic bond is a chemical bond between two atoms in which one atom donates its electron to another atom.

Examples of matter include a cup of coffee and the air we breathe, while energy is seen as sunlight shining through a window. Matter consists of substances that have mass and occupy space, and energy is the capacity to perform work or bring about change.

Examining the world around us, we can find numerous examples of matter and energy. For instance, a cup of coffee on your desk is an example of matter, containing energy in the form of heat.

Another example of matter would be the air you breathe, which is a mixture of gases like nitrogen, oxygen, and carbon dioxide. As for energy, sunlight streaming through a window illustrates energy in the form of light and heat.

These examples help us understand that matter is anything that has mass and takes up space, while energy is the capability to do work or cause change.

Matter can exist in different states, including solid, liquid, and gas. For example, ice is water in its solid state.

When absorbing energy, this ice can melt into liquid water, exemplifying a phase change that involves energy transfer. Alternatively, water vapor condensing into liquid showcases a phase change where energy is released.

To comprehend the complexities of these transitions and the role of energy, it is vital to explore the conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.

Investigations in this area could include lab experiments verifying the law of conservation of energy by observing phase changes and measuring the energy involved.
