=32 g/mol
From the balanced chemical equation,
2×2=4 g of hydrogen requires 32 g of Oxygen to react completely
Answer:
the second one filter for dissolved
Explanation:
Answer: m-%(Ca) = 40.08 / 110.98
Explanation: molar mass of CaCl2 is 40.08+ 2·35.45 = 110.98
Think you have one mole substance. It contains 40.08 g Ca
Between the ages of 40 and 50, the number of taste buds decreases, and the rest begin to shrink,losing mass vital to their operation. After age 60, you may begin to lose the ability to distinguish the taste of sweet, salty, sour, and bitter foods.
Answer:
higher temperature → more kinetic energy → more space between particles higher volume
Explanation:
Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature is directly proportional to the average kinetic energy of gas particles.
The following sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory:
higher temperature → more kinetic energy → more space between particles higher volume
