Answer:
Tin(IV) Oxide + Carbon = Tin + Carbon Monoxide
Explanation:
Answer:
2HCI + Na2S ----> H2S + 2NaCl
Explanation:
For a balanced chemical equation, the number of moles of atoms on the reaction side must equal the number of moles of atoms on the product side, in accordance with the law of conservation of mass.
The correct answer is:
2HCI + Na2S ----> H2S + 2NaCl
Since it has equal number of moles of each atom on both sides of the equation: 2 atoms each of hydrogen, chlorine, and sodium on both sides of the equation as well as 1 atom of sulphur on both sides of the equation.
1. One reason it is liquid while the mineral are always solid.
2. It came from organic materials
A covalent bond is formed between two atoms by sharing electrons. The number of bonds an element forms in a covalent compound is determined by the number of electrons it needs to reach octet.
I believe its 10^23 u r saying
then no. of moles= 9.03*10^23/6.02*10^23=1.5mole
