There will be two atoms of phosphorus in the 1.75 mol of calcium phosphate.
Atoms are the smallest unit of matter. In a chemical reaction, the number of atoms shows the quantity of an element in the compound or reaction. Phosphorus is a chemical element that is preset in the periodic table.
In calcium phosphate, Ca3(PO4)2, the number of atoms can be calculated by counting the number of moles that is given in the equation.
The number of atoms of calcium is 3, and the number of phosphorus atoms is 2.
Now given the 1.75 mol of calcium phosphate, so the number of atoms of phosphorus will be the same in any number of moles of calcium phosphate. So there will be 2 atoms of phosphorus in the given equation.
Thus, the number of atoms is two.

Answer:
It has 2 phosphorus atoms in 1 mol
so for 1.75 mol =2×1.75

0.001011 g
0.000001101 kg
0.0001011 g
For this case, the first thing we are going to do is convert all the numbers to the same unit.
For this, we use the following conversion:
1 Kg = 1000 g
We then have the following numbers:
1) 0.00001101 kg = (0.00001101) * (1000) = 0.01101 g
2) 0.001011 g
3) 0.000001101 kg = (0.000001101) * (1000) = 0.001101 g
3) 0.0001011 g
Therefore, the largest amount in grams is:
0.01101 g
Answer:
0.00001101 kg = 0.01101 g

B)61.05 kJ
C)63.09 kJ
D)68.60 kJ
Energy released from changing the phase of a substance from the gas phase to liquid phase can be calculated by using the specific latent heat of vaporization. The heat of fusion of water at 0 degrees Celsius is 40.7 kJ/mol. Calculation are as follows:
Energy = 27.9 g (1 mol / 18.02 g) x 40.7 kJ/mol
Energy = 63.09 kJ
Answer:
C- 63.09 kJ
Explanation:
I have several degrees
For the given chemical reaction, 15 moles of sulfur are required to produce 15 moles of sulfur dioxide.
A chemical equation can be defined as a representation of a chemical reaction in the form of symbols of the substances. A chemical equation consists of contributing reactants in the reaction, formed products, and their physical states.
The chemical equation in which the number of atoms of each element is equal on both sides of the equation is called a balanced chemical equation.
The law of conservation of mass follows by a balancing of a chemical equation therefore, the total mass of the elements on the reactant side must be equal to the total mass of elements on the product side.
Given, the chemical equation is: S + O₂ → SO₂
From the above equation, we can say that one mole of sulfur produces one mole of sulfur dioxide.
Given the moles of the sulfur dioxide = 15 moles
The moles of sulfur required to make 15 moles of sulfur = 15 moles
Therefore, 15 moles of sulfur are required for the given conditions.

(2) molecular structures
(3) ionization energies
(4) nuclear charges
Answer:
Due to molecular structures.
Explanation:
The different forms of phosphorus (white, black or red) are allotropes of phosphorus.
They differ in molecular structures.
White phosphorus: It has four phosphorus which form a tetrahedral shape.
Black phosphorus : It has orthorhombic structure and due to interlinked six membered rings, it is least reactive.
Red phosphorus: It is formed on heating white phosphorus. It is initially amorphus and turns crystalline on further heating.
