Answer:
the answer to your problem is A.Subscript...BRAINLIEST
Answer:
height(h)=10 m
acceleration due to gravity (g)=10 m/s^2
mass (m)=?
potential energy=67
or,mgh= 67
or,m×10×10=67
or,m=67/100
or,m=0.67 kg
Therefore,m= 670 grams
Its strontium and oxygen.
A balanced chemical reaction equation is one in which the number of atoms of each of the atoms are the same on both sides of the reaction equation.
<h3>Balanced reaction equation</h3>
A balanced reaction equation is a type of reaction equation in which the number of atoms of each reactant on both sides of the reaction equation are the same.
Let us now try to balance each reaction;
- 2H2 + O2 ----> 2H2O
- S8 + 12O2 -------> 8SO3
- 2HgO ----> 2Hg + O2
- Zn + 2HCl ------> ZnCl2 + H2
Hence a balanced chemical reaction equation is one in which the number of atoms of each of the atoms are the same on both sides of the reaction equation.
