Atomic number of C is 6. Hence, there are 6 electrons in carbon.
The electronic configuration of carbon is 1s2, 2s2, 2p2
Here, there are 2 unpaired electron. However, C2+ ions have 2 electrons less as compared to C.
Hence, electronic configuration of C 2+ ion is 1s2, 2s2. All the electrons are paired in this system. So there are no unpaired electrons in C 2+ ion.
Answer:
36.08%
Explanation:
We are given the overall formula of the compound as: CuSO4•5H2O
Now, atomic mass of the elements are;
Cu = 63.55 g/mol
S = 32.07 g/mol
O = 16 g/mol
H20 = 18.02 g/mol
Now, let's calculate the total mass of the compound:
(63.55 g/mol) + (32.07 g/mol) + 4(16 g/mol) + 5(18.02 g /mol) = 249.72 g/mol
From the above, water in the compound is 5(H20)
Thus, total water atomic mass = 5 × 18.02 = 90.1 g/mol
Thus, percentage of water = (atomic mass of water/total mass of compound) × 100%
Percentage of water = (90.1/249.72) × 100% = 36.08%
Hello!
<span>Carbonic acid is referred to as volatile acid because it is produced from a gas that evaporates quickly.
Volatility is the likeliness of a substance to vaporize. That is the tendency of the substance to pass to the gaseous phase. That means that these substances have a high vapor pressure. Coming from a gas, Carbonic Acid has a high tendency to pass to the vapor phase.
Have a nice day!</span>
Answer:
The reaction between zinc and acetic acid is a single-replacement reaction. During this type of reaction basically one element replaces one compound.
The balanced equation for the reaction between zinc and acetic acid is
Zn(OH)_2 +2CH_3 COOH ----> Zn(CH_3COO)_2+2H 2O
Or this might help too!
Balanced Chemical Equation
A balanced chemical equation is defined as the chemical equation which has an equal number of atoms on both sides of the reaction arrow. A balanced chemical equation is based on the law of conservation of mass.

Answer:
The volume of the gas will be 573.52 mL.
Explanation:
Boyle’s law states that <u>the pressure of a fixed amount of gas at a constant temperature is inversely proportional to the volume of the gas</u>.
The equation for Boyle's law is:
P₁V₁ = P₂V₂
We want to know V₂, that is, the volume of the container after the compression. We rearrange the equation and calculate:
V₂ = P₁V₁ ÷ P₂
V₂ = 1.14 atm × 815 mL ÷ 1.62 atm = 573.52 mL
