Answer:
A is the answer i am pretty sure
The Milliliters that occupy when its pressure is 755 mmhg is calculated using Bolyes law fomula
that is P1v1 = p2 V2
p1= 735mmhg
V1= 350 Ml
P2= 755 mm hg
V2= ?
from the formula above V2 is therefore= p1V1/P2
= 350 x735/755= 340.73 Ml
→ 
is the balanced form of the chemical equation.
<h3>What is the balanced equation?</h3>
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products.
12 hydrogen, 35 oxygen, and 22 hydrogens are present on both sides of the reaction.

It’s the third diagram. Gases are by far the least dense of the three main states of matter. Liquids and solids are of comparable density. Liquids assume the shape of their containers, and solids have a definite shape.
You can describe the particles of each state on the nanoscale to contribute more. Particles of a solid mostly vibrate in place and are rigidly locked together. Particles of a liquid flow past each other more, but are still tightly packed. Particles of a gas seldom even collide and have minimal attractions to each other.
You can expand on this by discussing the kinetic energy of each particle. Gases are the most energetic. Liquids second most. Solids least.
