In a given neutral atom, actually the number of protons
and electrons are equal. So ideally in this case the number of electrons should
also be 16. However we have an ionic charge of negative 2. Since it is
negative, this means there are 2 more electrons than protons, hence the answer
is:
<span>18 electrons</span>
Answer:
Decomposition reaction
Explanation:
2NO —> O2 + N2
The above equation clearly indicates decomposition because a single reactant (NO) produces two products (O2 and N2). Decomposition reaction is a reaction in which a single compound breaks down into two or more elements or compound as seen in the equation above.
An electromagent is being shown. Because the picture is showing how to put the lightnulb in and where it is
Answer:
(a) HCl
(b) HCl
(c) HCl
(d) HCl
Explanation:
<em>Given: </em>0.50 mol of CH₄ and 1.0 mol of HCl
Using stoichiometry we can calculate the answers to parts a, b, c, and d.
<h3>Part (a) </h3>
# of moles × Avogadro's number = # of atoms or molecules
Avogadro's number: 6.02 * 10²³
HCl has more atoms than CH₄.
<h3>Part (b) </h3>
This is calculated the same way as Part (a); HCl has more molecules than CH₄.
<h3>Part (c) </h3>
Molar mass of CH₄ = 16.04 g/mol
Molar mass of HCl = 36.458 g/mol
HCl has a greater mass than CH₄.
<h3>Part (d)</h3>
Assuming STP:
Molar volume of any gas at STP is 22.4 L/mol.
HCl has a greater volume than CH₄.
