Answer:

Chlorine and bromine

Explanation: The chlorine and bromine acts as reactive gases and destroy the ozone  present in the stratospheric ozone.

The ozone layer is present in the stratosphere to filter the harmful rays of the sun that is harmful for the people living on earth.

A chlorine or bromine molecule can destroy thousand of the ozone molecules before it leaves the stratosphere.

So, a single bromine or chlorine atom can affect the ozone layer.

V = KT  and T = V/K

3.5=k(35+273) = 308k

k=3.5/308 =0.011

new T=7.0/0.011=636K = 636-273 =363C

When it acts as a base, which atom in hydroxylamine accepts a proton?
Rashid [163]
<span>The oxygen atom accepts the proton. The oxidation number of O is -2, meaning that there are two unshared electrons in the valence shell; In the ClO- ion, one of these is shared with the Cl- ion, leaving an unshared electron on the oxygen atom, which is what the hydrogen atom shares its electron with, becoming the proton accepted by the O atom.</span>

Why does increasing the temperature of a reaction cause the reaction rate to increase?
Tems11 [23]
The temperature of a reaction causes its rate of reaction to increase because the heat inputted into the solution excites the electrons that make up the solution, therefore making them move faster, colliding more often with other molecules of the solution. This increase in collision rates causes the rate of reaction to increase.

I'm afraid I won't pass. And very nervous. Can you help me please.
daser333 [38]
Just look at the number in front also called coefficient (you have to balance the equations first, but all the questions here are balanced, so no worries). for q1.
in the balanced equation, the number in front of aluminum oxide is 2 (2 - this number Al2O3) and for aluminium is 4 as in (4 Al). so the ratio is 2:4. simplified it is 1:2. or write it out fully
2 Al2O3: 4 Al
ignore everything after the number.
2:4
same as 1:2
Aluminium oxide to oxygen
2 Al2O3: 3 O2
2:3
aluminum to oxygen
4 Al: 3 O2
4:3

question 2
Mercury oxide to Mercury
2 HgO : 2 Hg
2:2
same as 1:1
Mercury oxide to oxygen
2 HgO : O2
since oxygen in this case does not have a number written in front of it, the default is 1.
2: 1.
you should be able to do the rest
