2. A. High cumulonimbus
3. A. Air pressure differences over the ocean cause fast, spinning winds.
4. C. Both form when warm air rises, then cools quickly to form clouds.
5. B. False
6. A. Tornado
Explanation:
A tornado is a column of air with high angular velocity whose lower end is in contact with the earth's surface and the upper end with a cumulonimbus cloud. It is short and short in duration, ranging from seconds to over an hour and destroying what is in its path on a narrow path.Storm clouds have their origin in the cumulus type. They are the ones that are isolated and that look like a white cotton ball.If it continues to grow, its upper part will be rounded and form like a small bald spot, called cumulonimbus calvus. Now they are associated with huge waterspouts, but without an electrical device. When lightning and thunder appear, we will have reached the mature phase of the storm and there is talk of cumulonimbus capillatus. Its upper part resembles a chapel or anvil, that is, the storm in its purest form.
Hurricanes are formed by the accumulation of thunderstorms that move over warm ocean waters. When the warm air from the storm and the ocean surface combine, they begin to rise in eddies. This generates low pressure on the ocean surface.The scale with which the intensity of hurricanes is measured is known as Saffir-Simpson, and it divides them into 5 categories according to the speed of their winds and cyclonic activity, which is an abnormal increase in sea level after a storm. The scale also calculates the damage that can occur when the hurricane makes landfall.In comparison to the rock it intrudes, what is the relative age of a dike?

If a urine sample has a pH of 4.60, calculate the concentrations of H3O+ and OH- in the sample
pH = 6.0 = - log [H3O+] taking anti log both sides we have 10^-6 = [H3O+] [OH^-] = Kw/[H3O+] = 1x 10^-14/10^-6 = 10^-8.
What is pH?pH is a numerical indicator of how acidic or basic aqueous or other liquid solutions are. The phrase, which is frequently used in chemistry, biology, and agronomy, converts the hydrogen ion concentration, which typically ranges between 1 and 1014 gram-equivalents per liter, into numbers between 0 and 14.
The hydrogen ion concentration in pure water, which has a pH of 7, is 107 gram-equivalents per liter, making it neutral (neither acidic nor alkaline). A solution with a pH below 7 is referred to as acidic, and one with a pH over 7 is referred to as basic, or alkaline.
The first employed the measurement to describe the hydrogen ion concentration of an aqueous solution, expressed in equivalents per liter.
Therefore, pH = 6.0 = - log [H3O+] taking anti log both sides we have 10^-6 = [H3O+] [OH^-] = Kw/[H3O+] = 1x 10^-14/10^-6 = 10^-8.

Which statement about an element’s average atomic mass is correct? a. It is determined by counting the number of isotopes in a sample of the element. b. It is equal to one-twelfth the mass of the most common isotope. c. It is a weighted average, so common isotopes have a greater effect than uncommon ones. d. It is based on an isotope’s charge, so negatively charged isotopes have a greater effect than positive ones.
The answer is: C. It is a weighted average, so common isotopes have a greater effect than uncommon ones.
Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).
Isotope of chlorine-35 has mass number 35. Mass number is sum of protons and neutrons, so number of neutrons in chlorine-35 is 18 (35-17).
Isotope of chlorine-37 has mass number 37. It has 20 neutrons (37-17).
Because the average atomic mass is closer to chlorine-35, there is more this isotope in nature.

Each of the compounds that you tests contained chlorine, which is a poisonous gas. Why was this test safe to perform (it was, or your lungs would have turned to mush) without a gas mask?
Chlorine Gas by itself is dangerous
Many compounds we use often contain chlorine, but we are still alive. When chlorine is part of a compound, such as table salt (NaCl) it remains fairly unreactive. It becomes dangerous when it's in the form Cl2. This is chlorine gas and it is quite reactive.
Which of the following substances has
a higher melting point than water?
A salt
B sugar
C flour
D all of the above
Answer:
D all of the above
Explanation:
Melting point represents the exact temperature at which the solid state changes to the liquid of a given substance. Water is one of the most commonly used elements to exemplify the melting point principle. For this solid state (ice) to take the form of liquid water, it must be exposed to a temperature of at least 0 °C. Thus, the melting point of water is equal to 0 °C.
The salt has a melting point of 801 ° C, the melting point of sugar is 185 ° C and the melting point of flour is 264 ° C. From this we can see that all these products have a higher melting point than water.
