There 567 calories in 100 grams of peanut. In 100 grams of peanut, 49 gram is the fat, 26 grams of protein, 16 grams of carbohydrates, Sodium is 18 mg, Potassium is 705 mg. Calcium is present in peanut about 9%, Iron is 25% , Vitamin B-6 is 15%  and Magnesium is 42% of their total weight. Oil content is high in the Peanut so this is the reason for high calories in peanut. It is a good source of proteins and potassium.

How to balance chemical equations
Sonbull [250]
To balance a chemical equation, you want the same amount of elements to equal the same on both sides.

Step1. Write equation out
[CH4 + Cl2 ---> CCl4 + HCl] 
C:1; H:4; Cl:2      C:1; H:1; CL:5   /// Cl = 5 since 4Cl +  1Cl

The Carbon element is balanced, but Hydrogen isn't.
 So to balance it we will add a coefficient behind HCl, so now 

[CH4 + Cl2 ------> CCl4 + 4HCL]
C:1; H:4; Cl:2      C:1; H:4; CL:8 ///// Carbon and hydrogen are balanced, but now Chlorine is not. Now we balance that element by addind a coefficiant behind CL2////

[CH4 + 4Cl2 -----> CCl4 + 4HCl]
C:1; H:4; Cl:8      C:1; H:4; CL:8  ///// So now that we added a 4*Cl2, it equals to Cl:8. So now what most people want to see is if every element is at its lowest balance, so we see if we can any coefficient lower. Just like simplifying if possible.
