Answer:
H1 = 63.3 kJ
Explanation:
When the steam at 100C contacts your skin, it is first condensed to water at 100C. The heat involved with this change in state is calculated using the latent heat of vaporization:
Q = ML = (25.0 g)(2.256 kJ/g) = 56.4 kJ
The water at 100C is then cooled to 34C. The heat involved with this temperature change is calculated using the specific heat capacity. (Because a temperature <em>change </em>is used here, it is not necessary to convert °C to K in order for the units to properly cancel)
Q = mcΔt = (25.0 g)(1kg/1000g)(4190Jkg⁻¹K⁻¹)(100C - 34C) = 6913.5 J = 6.9135 kJ
The total heat H1 that is transferred to the skin is the sum of the two heat values above:
H1 = (56.4 kJ) + (6.9135 kJ) = 63.3 kJ

Answer:
The Phosphorylated glucose(glucose +inorganic phosphate), with the energy supplied from ATP hydrolysis formed glucose 6- phosphate, which is later converted to 2 molecules of fructose 6-phosphate- this is phosphorylation.And represented the fate of glucose -6-phosphate.
The fructose 6-phosphate are converted to triose phosphate- which is a 2-molecules of 3C compound. The latter is oxidized by NAD→ NADH+ to form intermediates in the glycolytic pathways .
These intermediates are converted to ribose 5-phosphates in the presence of transketolase and transaldolase enzymes.And they are finally converted to pyruvate in the glycolytic pathway with the production of 2ATPs per molecule of glucose.
Basically the phosphate pathway reaction is very slow due to enzyme catalysis.

Moles of acetic acid ,
Mole fraction of water :
Therefore, mole fraction of water in this solution is 0.645 .
Hence, this is the required solution.
Answer:
MgCl₂ + H₂ ---> 2 HCl + Mg
Explanation:
Since you have not given any products, I am going to assume that this is a single-displacement reaction. In these types of reactions, an element is being swapped for another in a compound. The unbalanced equation would look like this:
MgCl₂ + H₂ ---> HCl + Mg
Mg does not have a subscript of 2 because it can exist by itself. As you can see, the reaction is not balanced. On the left side, there is 1 Mg, 2 Cl, and 3 H. On the right side, there is only 1 of each. The balanced equation would look like this:
MgCl₂ + H₂ ---> 2 HCl + Mg
Now, there is 1 Mg, 2 Cl, and 2 H on both sides.
