1. The burning of propane creates different substances: propane and oxygen combine to create water and carbon dioxide:
<span><span>C<span>3</span>H<span>8</span></span> + 5 <span>O<span>2</span></span> becomes 3 CO2 + 4 <span>H<span>2</span>O</span> + heat
</span><span>
2. When NaCl melts, it is changing state, but it is still the same NaCl.
3. When gaseous CO2 deposits it is changing state, but it is still the same CO2.
4. When (presumably liquid) water solidifies, it is changing state, but it is still the same water.
So the answer is 1.</span>
Sp2 hybridization forms 1 sigma bond and 1 pi bond.
I’m in chemistry too. Giving this my best guess I’d say
Independent: Gem Mines
Dependent: Gem clarity
Controlled: Temperature
Answer:- 14.0 moles of hydrogen present in 2.00 moles of ![[tex]C_6H_7N](https://tex.z-dn.net/?f=%20%5Btex%5DC_6H_7N)
.
Solution:- We have been given with 2.00 moles of 
and asked to calculate the grams of hydrogen present in it. It's a two step conversion problem. In first step we convert the moles of the compound to moles of hydrogen as one mol of the compound contains 7 moles of hydrogen. In next step the moles are converted to grams on multiplying the moles by atomic mass of H. The calculations are shown as:
= 14.0 g H
So, there are 14.0 g of hydrogen in 2.00 moles of .
