Answer:
4.36 g of Carbon
Solution:
Step 1: Calculate the %age of Carbon in given Solid as;
Mass of Carbon = 35.8 g
Mass of Hydrogen = 3.72
Total Mass = 35.8 g + 3.72 = 39.52 g
%age of Carbon = (35.8 g ÷ 39.52 g) × 100
%age of carbon = 90.58 %
Step 2: Calculate grams of Carbon in 4.82 g of given solid as;
Mass of Carbon = 4.82 g × (90.58 ÷ 100)
Mass of Carbon = 4.36 g
The loss or gain of electrons
Explanation:
The loss or gain of electrons determines if an atom will become a cation or anion.
A cation is a positively charge ion
An anion is a negatively charged ion.
In an atom, we have sub-atomic particles:
Protons are the positively charged particles
Electrons are negatively charged
Neutrons carry no charges
Only electrons can be lost or gained in chemical processes that forms cations and anions.
When a neutral atom gains electron, it has more electrons than protons. This makes it negatively charged and we call it an anion.
When a neutral atom loses an electron, the number of protons is more. We call it a cation.

Answer:
The answer to your question is: 234.7 cans
Explanation:
data
caffeine concentration = 3.55 mg/oz
10.0 g of caffeine is lethal
there are 12 oz of caffeine in a can
Then
3.55 mg ----------------- 1 oz
x mg -----------------12 oz (in a can)
x = 42.6 mg of caffeine in a can
Convert it to grams 42,6 mg = 0.0426 g of caffeine in a can
Finally
0.0426 g of caffeine ------------------ 1 can
10 g of caffeine ----------------- x
x = 10 x 1/0.0436 = 234.7 cans
Answer: C excess reactant
Reason: It is not catalyst because catalyst are not consumed. It is not product because it was one of the reactants. It is not limiting because there was excess left over.
