Answer: C) Heat
What I know so far is that heat makes it harder for the electrons to reach the source, thus making it hard to collide with the nucleus, but I’m not sure so you can see if it’s correct.
To balance a chemical reaction, we need to remember that the number of each atom in the reactant and the product side of the equation should be equal. So, from the reaction <span>P4(s) + Cl2(g) = PCl3(l), there are 4 P atoms in the reactant, the P atoms in the prodcut side should be 4 as well. We balance as follows:
</span> P4(s) + 6Cl2(g) = 4PCl3(l)
<span>
Therefore, the coefficient of the PCl3 should be 4.

Answer:
All of the above
Explanation:
At the sea level the pressure that we experience is only due to the air that is surrounding us. This is atmospheric pressure and at the sea level it is nearly 14.5 pounds per square inch.
But, as we go down below the sea level, the pressure increases because an additional hydrostatic pressure starts to act upon our body. The deeper we dive the grater will be the pressure that we experience. For every dive of 33 feet, this pressure increases by about 14.5 pounds and goes on increasing as the depth increases.
Answer:
1.8dm3
Explanation:
we use the formulae
(p1*v1)/t1=(p2*v2)/t2
since we are looking for volume 2 we make v2 subject of formula
p2=(p1*v1*t2)/v2*t1
where p1=1
t1=25+273=298
v1=1.5
t2=100+273=373
p2=1
inputting our values we have
(1*1.5*373)/1*298
559.5/298=1.8
1.8dm3
