Total energy of an isolated system remains constant throughout time; this is referred to as conservation of energy.
Answer:
Electrically neutral atoms simply possess the same number of electrons as protons. This gives the objects a balance of both type of charge. There are <u>11 electrons</u> and 10 protons. This results in an imbalance of charge.

Answer:
The answer to your question is letter b) X
Explanation:
Data
W = 5 units
X = 6 units
Chemical reaction
2W + 3X ⇒ 3Y + Z
To determine which reactant is the limiting reactant, we must use proportions:
-Theoretical proportion W / X = 2 / 3 = 0.67
- Experimental proportion W / X = 5 / 6 = 0.83
As the experimental proportion is higher than the theoretical proportion, we conclude that the amount of W is higher in the experiment so the limiting reactant is X.
The average atomic mass in amu of element X is 58.42 amu
The average atomic mass is the sum of the mass number of each of the isotopes multiplied by their respective abundances.
So;
The average atomic mass of element X is;
(58 * 0.68) + (60 * 0.26) + (0.06 * 62)
= 39.44 + 15.26 + 3.72
= 58.42 amu
The average atomic mass in amu of X is 58.42 amu.
