Answer:
B,C,D
Explanation:
The yield of CCl4 depends on the amount of CH4 in a 1:1 ratio. The amount of Cl2 is twice that of CH4 hence some must be left over. To ensure that all the Cl2 is used up, more CH4 must added to the system.
Answer:
Mass = 84.82 g
Explanation:
Given data:
Number of molecules of CaSO₄ = 3.75× 10²³
Mass in gram = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
3.75× 10²³ molecule × 1 mol / 6.022 × 10²³ molecules
0.623 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.623 mol × 136.14 g/mol
Mass = 84.82 g
Answer:
Strong acids and bases both denature proteins by severing disulphide bonds and at higher temperatures, can break proteins into peptides, or even individual amino acids.
