The reaction of sodium bromide with chlorine gas is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).
<h3>What is sodium bromide?</h3>
Sodium bromide is an inorganic compound, white, crystalline with high melting point.
The reaction between halogens is redox reaction
Oxidation – 2Br⁻ ? Br₂ + 2e⁻ loss of electron.
Reduction – Cl₂ + 2e⁻ ? 2Cl⁻ gains of electron.
Thus, the correct option is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).

760 mmHg = 1 atm Therefore 30 atm = 760 * 3 mmHg = 2280 mmHg p1 = 700 mmHg p2 = 2280 mmHg You can compare them from there. You may also convert mmHg to atm by dividing by 760.
Your answer would be 243.2 mm Hg
I think the answer is Endothermic. Since the question says "absorbs," endo means to "go in" sort of and exo means to exit.
exo = exit
endo = enter

Sorry if I'm wrong, hope I helped. :)
Answer:
They fall slower.
Explanation:
moon's gravitation force is effected by the mass of the moon
but because the moon has less mass,
objects fall slower because it has less gravitation force

Answer:
i) 
ii) 
ii) 
Explanation:
As the initial and final states of the sample are the same, the ΔU of the sample is, for the three cases
since 
i)Reversibly
so
can be calculated by

and because of the first law of thermodynamics

ii)Irreversibly with 
we can calculate
by the law of ideal gases
then w can be calculated by

and

iii)a free expansion
so
(there's no work at vaccum) and
