Answers
Answer:
R717
Explanation:
For an equipment room having R717 in the systems, a refrigerant detector is not needed. Provided the mechanical ventilation systems are working continuously so that the leaked refrigerant is being thrown out of the room

Answer:
Option A = 1:1
Explanation:
The atoms of calcium and sulphur when react their ration is 1:1. The charge on calcium is +2 and on sulphur is -2.
Ca⁺²S⁻²
The +2 and -2 charges are cancel out and overall charge will be zero.
CaS
so their atomic ratio will be 1:1

What is Avogadro's number?
The Avogadro number is the proportionality factor which is the number of particles such as atoms, molecules, or ions in one mole of a substance.
Avogadro's number possesses a numeric value of 6.022 × 10²³ reciprocal moles. Avogadro's constant is named by Stanislao Cannizzaro after the scientist Amedeo Avogadro.
Given, the mass of the carbon in sample = 6 g
The number of atoms of one mole of carbon = 6.022 × 10²³
The atomic mass of one mole of carbon = 12 g
It means 12 g of the carbon has atoms = 6.022 × 10²³ carbon atoms
Then 6 grams of carbon will have atoms = (6/12) × 6.022 × 10²³
= 3.011 × 10²³ carbon atoms
Therefore, the atoms of carbon in 6 g of sample of carbon are 3.011 × 10²³ atoms.

Convert moles to atoms [moles * 6.02 x 10^23] = Atoms
Half of 6.02 x 10^23 is 3.01 x 10^23 so here is our answer.
