Answer:</h3>
2 H₂ + O₂ → 2H₂O
<h3>
Explanation:</h3>
- The equation that shows the conservation of atoms is the balanced one.
- In this case, the balanced equation is;
2 H₂ + O₂ → 2H₂O
Because it has 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
- Chemical equations are balanced to obey the law of conservation of mass that requires the mass of the reactant to be equal to the mass of the products.
- Balancing chemical equations makes the number of atoms of each element in the equation equal, thus conserving the mass in the chemical reactions.
Answer:
A. 25Mn45^+
B. 45Rh69^+2
C. 53I142^-
D. 97Bk^243
Explanation:
Generally Atomic mass (A)= no of protons (p) + no of neutrons (n)
No of Neutrons (n)=A-p
No of protons = Atomic number
Symbol for nulclide: zX^A
Z is Atomic number, A is Atomic mass
And X is symbol of element
Answer:
210
Explanation:
according to vectors since they are in two different direction u minus them
F1 =10 F2=220
F1 has a forward direction
while f2 goes backward
