Answer:
1) the carbon and hydrogen valence electrons
Explanation:
The lewis dot diagram illustrates how electrons are arranged round atoms in a molecule. The dots represents the;
1) the carbon and hydrogen valence electrons
Answer:
M
Explanation:
Equation for the reaction is as follows:
+ 
⇄ 
By Applying the ICE Table; we have
+ ⇄
Initial x 0.0025 M 0.0010 M
Change 0 0 0
Equilibrium x 0.0025 M 0.0010 M
![K_c =\frac{[CO_2]^2}{[CO]^2[O_2]}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%7B%5BCO_2%5D%5E2%7D%7B%5BCO%5D%5E2%5BO_2%5D%7D)
Given that 
; Then:
M
∴ The equilibrium concentration of CO = M
Answer:
y or z one of those two i think its z but im so sorry if im wrong if not z then try y also I learned this last year.
<span>I think There should be a valanced state in every atom. (Valanced state means, 8 electrons in the outer most orbit) In case take a atom has 8 electrons in the outer orbit, so when bonding the two atom to form a molecule, there is a Ionic Bond (because of both atoms has its own valanced electron(8 electrons in outer most orbit).</span>
Answer:
0.625 moles MgCl₂
Explanation:
Since you were given a molarity value and volume, you should use the molarity equation to find moles. The equation looks like this:
Molarity (M) = moles / volume (L)
To find moles, you need to (1) convert mL to L (by dividing by 1,000) and then (2) plug the numbers into the formula and simplify to find moles. The final answer should have 3 sig figs as the lowest amount of sig figs in a given value is 3.
<u>Step 1:</u>
650.0 mL / 1,000 = 0.6500 L
<u>Step 2:</u>
Molarity = moles / volume
0.962 M = moles / 0.6500 L
(0.962 M) x (0.6500 L) = moles
0.625 = moles
