If you mean: 6h+7 then 6*5 plus 7 = 37
58
It is: 16-(3*4) = 4
It is: (5*12)-2 = 58
The expression h + 56 can't be simplified. If you assign a value to h, you can calculate the sum.

If you mean: 6 = x-1 then the value of x is 7
It is: 16-(3*4) = 4
It is: (5*12)-2 = 58
To find the Ka value for HF, we can use the equation for the dissociation of HF into H⁺ and F⁻ ions: HF ⇌ H⁺ + F⁻. First, calculate the initial concentration of HF using the given pH. Then, determine the concentrations of H⁺ and F⁻ ions at equilibrium. Finally, use these concentrations to calculate the Ka value using the equation Ka = [H⁺][F⁻] / [HF].
Do you mean h/2 -6 = 10 if so then the value of h is 32
To calcualte NCV you need calorific value on GAR, H on gar and Total moisture.
