A dichromate ion has 56 valence electrons. Valence electrons are the electrons that are present in an atom which are responsible or allows the formation of a chemical bond. When you draw the lewis structure of a dichromate ions, you will have to calculate the valence electrons by (6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 + 6 ) – (-2) = 56.
Answer:
It has greater concentration of hydronium ion than hydroxide ions
Answer:
40 C atoms
Explanation:
Step 1: Write organic compound
10C₄H₁₀
We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.
We are given that we have 10 moles of C₄H₁₀.
Therefore, we have 4 · 10 = 40 atoms C
if you go to a desert and your in the middle of nowhere you get thirsty and have no water and need to find water to drink so the sun is the reason it heats faster than water in the desert
