O and 100 - X % by mass of MgSO
4
.7H
2
O. 5.0 g of mixture will contain 0.05X g CuSO
4
.5H
2
O and 5.0 - 0.05X g MgSO
4
.7H

Pls mark it as branliest answere thanks
Probably protons because when it changes it becomes a whole new element
Talk about photosynthesis, the nitrogen cycle carbon cycle etc. For websites I suggest Brittanica or really any secure website that ends in .org, they tend to be the most accurate.
When carbon bonds with 4 hydrogen atoms which is methane having sp3 structure so it is tetrahedral. electricity is conducted by electrons so graphite conducts by free and delocalised sea of electrons.
