Answer:

Q = 9460 Kj

Explanation:

Given data:

Mass of copper = 2kg

Latent heat of vaporization = 4730 Kj/Kg

Energy required to vaporize 2kg copper = ?

Solution:

Equation

Q= mLvap

It is given that heat required to vaporize the one kilogram copper is 4730 Kj thus, for 2 kg

by putting values,

Q= 2kg ×  4730 Kj/Kg

Q = 9460 Kj

The transfer of a phosphate group to a molecule or compound is called The transfer of a phosphate group to a molecule or compoun
ki77a [65]

Answer:

Phosphorylation

Explanation:

Phosphorylation is the term used to describe the transfer of a phosphate group (PO34-) from a donor to a receptor molecule or compound. The process of phosphorylation is usually catalysed by a biological enzyme called KINASE.

Phosphorylation can either be addition of an inorganic phosphate to a molecule. For example, addition of phosphate group to ADP to form ATP, or the donation of a phosphate group to another molecule, e.g transfer of phosphate from ATP to glucose to form glucose-6-phosphate during glycolysis.

Equal volumes of 1 molar hydrochloric acid (hcl) and 1 molar sodium hydroxide base (naoh) are mixed. after mixing, the solution
Mademuasel [1]
HCl is a strong acid therefore complete ionisation takes place 
HCl ---> H⁺ + Cl⁻
1 mol of HCl dissociates to form 1 mol of H⁺
NaOH is a strong base therefore complete ionisation takes place 
NaOH ---> Na⁺ + OH⁻
1 mol of NaOH dissociates to form 1 mol of OH⁻ ions
equal number of moles of HCl and NaOH will dissociate to give out an equal number of moles of H⁺ and OH⁻ ions.
H⁺ + OH⁻ --> H₂O
equal amount of H⁺ and OH⁻ together forms H₂O
since all the H⁺ and OH⁻ have now reacted to form water molecules the solution now becomes neutral as there are no excess H⁺ ions to make the solution acidic and no excess OH⁻ ions to make the solution basic.

Therefore the solution will be neutral.
