Liquid antacids contain suspensions of bases like aluminum hydroxide and magnesium hydroxide. These are usually the bases that can neutralize the stomach acids.
The chemical equation representing the neutralization reaction of stomach acid, HCl and antacid, aluminum hydroxide: Three moles of hydrochloric acid reacts with one mole aluminum hydroxide to give the salt, aluminum chloride and three moles of water.
Answer:
<u>C. 0.5M</u>
Explanation:
Molarity =
Moles of solute/ Liters of solution (L)
5.0 moles/10L = 0.5 M

When exercising, we respire. When we do not do exercise that often, our muscles will not be able to withstand long amounts of exercise due to lack of oxygen. This is called Anaroebic Respiration. This is when glucose turns to Lactic Acid immediately. Anaerobic respiration releases less energy.
Answer:
V = 267.2 L
Explanation:
Given data:
Volume of balloon = ?
Mass of helium = 2.50 g
Temperature of gas = 180°C
Pressure = 0.87 atm
Solution:
Number of moles of helium:
Number of moles = mass/molar mass
Number of moles = 2.50 g/ 4 g/mol
Number of moles = 0.625 g
Volume of helium:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
0.87 atm× V = 0.625 mol × 0.0821 atm.L/mol.K×453 K
V = 232.45 atm.L /0.87 atm
V = 267.2 L
