Answer:
Bonding electron pairs
Explanation:
Sulfate (SO₄²⁻)
Valence electrons of sulfur = 6
Valence electrons of oxygen = 6
Charge = 2 (Negative which means that the electrons are being added)
The total number of the valence electrons = 6 + 4(6) + 2 = 32
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is:
<u>Since, all the electrons pairs around the central atom, sulfur is bonded. So, the electron pairs are bonding electron pairs.</u>
Answer:
"When a gas is trapped inside a container which has a fixed size (its volume cannot change) and the gas is heated, the particles will gain kinetic energy which will make them move faster. This causes the force on the walls of the container to increase and so the pressure increases."
I hope this helps you!
Answer:
36 electrons
Explanation:
<em>But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons.</em>
Answer:
Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light. LPG is another example of a familiar process in which both the chemical and physical changes take place.
Answer:
0.027mol
Explanation:
9M NaOH tells us that there is 9 mol of NaOH per L of NaOH
converting 3mL to L = 0.003L
0.003L * 9 mol/L = 0.027mol
