which chlorite kills bacteries and removes color from clothes
Answer:
When used properly (it should always be diluted with water before use), chlorine bleach is safe for disinfecting surfaces. It kills harmful germs and bacteria and sanitizes clothes in the laundry.
Answer:
bleach

Mutations that neither benefit nor harm the organism have effect on the organism's survival.
No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
Answer: Mutations that neither benefit nor harm the organism have A NEUTRAL effect on the organism's survival.
Explanation:
If it is non beneficial and not harmful, it will not do anything to effect the organism's survival. So it is neutral.
Neutral definition: Not helping or supporting either side in a conflict.
What is the pressure (in torr) inside a 4.0 liter flask at 24°C of 7.2 grams of nitrogen gas (remember that nitrogen gas is diatomic)?
Answer:
1190.2 Torr
Explanation:
Data Given:
Volume of a nitrogen gas ( V )= 4.0 L
temperature of a gas ( T ) = 24 °C
Convert °C to K
T = °C + 273
T = 24 + 273 = 297 K
mass of nitrogen gas (m) = 7.2 g
Pressure of a gas ( P ) =? in Torr
Solution:
Formula to be used
PV= nRT . . . . . . .(1)
As we Know
n= m/M
So, the equation 1 can be written as
PV = (m/M)RT
Rearrange the above formula
P = (m/M)RT / V . . . . . . . . . . (2)
Where
R is ideal gas constant
R = 62.37 L Torr mol⁻¹ K⁻¹
M = molar mass of N₂
molar mass of N₂ = 2(14) = 28 g/mol
m = mass of N₂ gas
Put values in equation 1
P = (m/M)RT / V
P = (7.2 g / 28 g/mol) 62.37 L Torr mol⁻¹ K⁻¹ x 297 K / 4.0 L
P = 0.257 mol x 62.37 L Torr mol⁻¹ K⁻¹ x 297 K /4.0 L
P = 4761 L Torr / 4.0 L
P = 1190.2 Torr
Pressure of gas (N₂) = 1190.2 Torr

Which structure is a valid representation of a hydrocarbon molecule?
Answer:
The formula for acyclic saturated hydrocarbons (i.e., alkanes) is CnH2n+2. The most general form of saturated hydrocarbons is CnH2n+2(1-r), where r is the number of rings. Those with exactly one ring are the cycloalkanes.
Explanation:
Answer:
An example of a hydrocarbon molecule structure is shown in the image below.
Explanation:
Hydrocarbons are organic compounds specifically made up of carbon and hydrogen atoms. The molecular structure consists of a framework of carbon atoms to which the hydrogen atoms are attached. The carbon atom chains can be linear or branched, and open or closed.
