PLEASE IM VERY CONFUSED

Directions: Write the formulas of the reactants and products, including the symbols for the state,
(s), (l), (g), (aq) - then balance the equations.

8. When a solution of hydrogen chloride is added to solid sodium bicarbonate (NaHCO3), the products are carbon dioxide, water and aqueous sodium chloride.

9. Ethyl alcohol (a liquid), C2H6O, burns in air to produce carbon dioxide and gaseous water.

10. Solid titanium (IV) chloride reacts with water, forming solid titanium (IV) oxide and aqueous hydrogen chloride.

11. During photosynthesis in plants, carbon dioxide and water are converted into glucose, C6H12O6, and oxygen gas.

12. Solutions of calcium hydroxide, Ca(OH)2 and nitric acid, HNO3, react to produce water and aqueous calcium nitrate, Ca(NO3)2.

8. the formula of the products are CO2(g) , H2O (l) and NaCl (aq)

Explanation:

s- solid

g- gas

l- liquid

aq- aqueous, means acid

These are the products of the equation, you can balance this by searching up a video on how to do so, or use a balance equations calculator online. Balancing is very easy tho.

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
