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 %
What? Is this a question or....

Explanation:
Glucose is the most common form of sugar in the blood and the body's primary source of energy. Glucose is derived from the meals we eat or produced by the body from other chemicals. The circulation transports glucose to the cells. Several hormones, including insulin, regulate blood glucose levels.
a simple sugar that is a component of many carbohydrates and is a vital source of energy in living things.
Blood sugar, often known as glucose, is the most common sugar present in the body. It is your body's major source of energy and comes from the food you eat. Glucose is carried by your blood to all of your body's cells, where it is used for energy.
Answer:
I believe the answer is D
Explanation:
C is not correct
The answer is
