there are more to this than just two of those. the answer is volvox and euglena
Answer:
<h3>The answer is 122.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 7 mL
density = 17.5 g/mL
We have
mass = 17.5 × 7
We have the final answer as
<h3>122.5 g</h3>
Hope this helps you
Answer: There are 0.056 moles present in 3.45 g of
.
Explanation:
Given : Mass = 3.45 g
Moles is the mass of substance divided by its molar mass.
Hence, moles of
(molar mass = 61.98 g/mol) is as follows.

Thus, we can conclude that there are 0.056 moles present in 3.45 g of
.
D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.
