Answer: -
If 13.3 mole of Co(NO₃)₂ are reacted, 26.6 mole of NaNO₃ are produced.
Explanation: -
The balanced chemical equation for the production of NaNO₃ from Co(NO₃)₂ is
Co(NO₃)₂ + Na₂SO₄ → 2 NaNO₃ + CoSO₄
From the balanced equation we see that
1 mole of Co(NO₃)₂ gives 2 moles of NaNO₃
13.3 mole of Co(NO₃)₂ gives moles of NaNO₃
= 26.6 mole of NaNO₃
Hey there!
27 tells us the sum of protons and neutrons is 27.
Al tells us we have 13 protons.
3- tells us that there are 3 more electrons than protons.
13 + n = 27
neutrons = 14
13 + 3 = 16 electrons
27Al3- has 13 protons, 14 neutrons, and 16 electrons.
Hope this helps!
Carbonated drinks have the air under pressure so that carbon bubbles are forced into the drink, keeping it carbonated. So when you open a can, the air under pressure in the can comes out of the can at a high speed, making a "whooshing" sound. The gas law that applies to this concept is the Boyle's Law (PV=k or P1V1=P2V2).
Answer:
a physical change does not change the composition (what it's made of) as a chemical change would.

it take many long time but i dont know accurate time
