Answer:
36.0 mL
Explanation:
First, write the balanced reaction.
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Calculate the moles of Ba(OH)₂:
0.500 mol/L × 0.0450 L = 0.0225 mol Ba(OH)₂
Use stoichiometry to find moles of HCl:
0.0225 mol Ba(OH)₂ × (2 mol HCl / mol Ba(OH)₂) = 0.0450 mol HCl
Now calculate the volume needed at the given concentration.
0.0450 mol HCl × (1 L / 1.25 mol) = 0.0360 L HCl
You need 36.0 mL of 1.25 M HCl.
Answer:
Explanation:
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Answer:
A
Explanation:
The mallet transfers kinetic energy, then that energy is transferred to the orange ball, then the purple ball, thus making the purple ball move

Answer:
The answer to your question is: letter A
Explanation:
A. Gas particles are in constant motion. This statement is true because this theory says that Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.
B. Gas particles attract each other. This statement is false because this theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
C. Gas particles lose their energy during collisions. This statement is false, this theory says that none of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.
D. Gas particles stick to the walls of their container. This statement is false, the theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
