If you mean carbs, then you don't eat as much pasta and bread and stuff like that. So practically, all of the good stuff. Use techniques. Tell yourself that it will make you thinner if you don't eat it. I also tell myself that I am stronger than this and that food shouldn't control me. It might or might not work for you.
Hope I could help!
Answer:
As hydrogen is more electronegative than boron, in BH3 the oxidation number of hydrogen should be taken as -1. (E. N. of B = 2.0 & E. N. of H = 2.1)
Suppose, oxidation number of B is x.
So, we can write, x + 3*(-1) = 0
=> x = +3
Therefore, oxidation num

Answer:
Q = 3.21 kJ
Explanation:
First, with the heat of hydration and the lattice energy, we can actually calculate the difference between those two to get the heat evolved per mole. In this case it would be:
657 - 639 = 18 kJ/mol
Now, the expression to get the heat is:
Q = m*ΔE
We already have the energy, now we need to get the moles of the cesium chloride.
The molar mass of cesium chloride is 168.36 g/mol, so the moles:
mole = 30/168.36 = 0.1781 moles
Finally the heat:
Q = 0.1781 * 18
Q = 3.21 kJ
