Answer:
Explanation: The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.
Answer:
increase the rate of a reaction without being consumed by the reaction
Explanation:
- Enzymes are biochemical catalysts that increase the rate of chemical reactions.
- They increase the rate of a chemical reaction without being consumed by the reaction.
- Enzymes increase the rate of chemical reactions by decreasing the activation energy of the reactants.
- Catalysts such as enzymes do not affect the free energy change of a chemical reaction (delta G). Therefore, delta G for a catalyzed and non-catalyzed reaction is equal.
The more salt that is dissolved in the water, the less oxygen will be dissolved in it.
The higher the temperature of the water, the less oxygen will be dissolved it in.
Answer:
temperature before the increase in CO2 was a few degrees lower than temperature after the increase.
Explanation:
CO2 in the atmosphere has the property of trapping heat by absorbing it. So, with increase in the level of CO2 in the atmosphere the more heat will be absorbed by it and hence the temperature before the increase in CO2 was a few degrees lower than temperature after the increase.
Level of CO2 ∝ Temperature of the Earth
Answer:
The answer to your question is: letter B
Explanation:
Data
3.58 x 10⁴ cal to joules
1 calories --------------- 4.184 joules
3.58 x 10⁴ cal----------- x
x = ( 3.58 x 10⁴ x 4.184) / 1
x = 149787.2 joules
x = 1.5 x 10⁵ J
