Answer:
it has 79 protons
Explanation:
the atomic number is equal to the number of protons an element has.
<h3><u>Answer;</u></h3>
10 percent
<h3><u>Explanation;</u></h3>
- Probability is a number that describes how likely it is that an event will occur.
- In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
- Therefore; as a percentage;
1/10 × 100 = 10 percent
- Hence; The probability of each individual event occurring is 10 percent
Answer:
2Al + 6H2O --> 2Al(H2O)3 + 3H2
Explanation:
aAl + bH2O --> cAl(H2O)3 + dH2
To balance this equation, the Al(H2O)3 is first multiplied by c = 2 to even out the water molecule.
Since we have done that, the reactant water molecule is balenced with b = 3 so that the difference in the Hydrogen in the aluminum hydroxide molecule and the reactant water molecule, which is 6 goes to the H2 (d = 3) in the product.
Then, the Al metal is balanced with a = 2 and then the reaction is balanced.
2Al + 6H2O --> 2Al(H2O) + 3H2
