Answer: Nucleus
Explanation:
<em>The </em><em><u>nucleus</u></em><em> is like a conductor of an orchestra because both control and coordinate activities. </em>
In a cell, the nucleus is considered to be the most important organelle due to it being the control center. Like a conductor does in an orchestra, the nucleus controls and coordinates activities to ensure the cell's survival.
It does this primarily by controlling protein synthesis due to it being the structure that houses DNA which in turn contains the instructions for synthesizing protein.
Answer:
Theoretical yield: 13.9 g
Percent yield: 94 %
Explanation:
The reaction is:
CaCO₃ → CaO + CO₂
We see that the reaction is correctly balanced.
1 mol of calcium carbonate can decompose to 1 mol of calcium oxide and 1 mol of carbon dioxide.
We convert the mass to moles: 24.8 g . 1mol / 100.08g = 0.248 moles
As ratio is 1:1, 0.248 moles of salt can decompose to 1 mol of oxide.
We convert the moles to mass: 0.248 mol . 56.08g /1mol = 13.9 g
That's the theoretical yield.
To determine the percent yield we think:
(Determined yield / Theoretical yield) . 100 → (13.1 / 13.9) . 100 = 94 %
If the net force is doubled, the acceleration would also be doubled.
This is the answer
