For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be produced
Answer:
29.9 g of CO₂ will be produced by the reaction.
Explanation:
This is the reaction:
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
First of all, we state the moles of each reactant:
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
The solid salt is the limiting reactant. Ratio is 2:1
2 moles of acid can react to 1 mol of salt
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
As we only have 0.680 moles of salt, we do not have enough.
Let's work at the product side. Ratio is 1:1
1 mo of salt can produce 1 mol of gas
0.680 moles will produce 0.680 moles of gas
We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂
The number of grams of Co2 should be produced is 29.9 g.
Calculation of the number of grams:Since
CaCO₃(s) + 2HCl (aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
So,
68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate
51.6 g . 1 mol/36.45g = 1.46 mol of acid.
Now the ratio should be 2:1 for the solid salt
And, there is 2 moles of acid can react to 1 mol of salt
So,
1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles
Now the product side the ratio is 1:1
So, that means
1 mo of salt can produce 1 mol of gas
So, the no of grams should be
= 0.680 mol . 44g / 1mol
= 29.9 g of CO₂

What causes infrared light to hit the ground?
Answer: The water vapor, carbon dioxide, methane, and other trace gases in the earth's atmosphere absorb the longer wavelength. These are all reasons why infrared waves hit the ground.
The water vapor, carbon dioxide, methane, and other trace gases in the earth's atmosphere absorb the longer wavelength. These are all reasons why infrared waves a part of electromagnetic spectrum hit the ground.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

non-Metals:
Nitrogen.
Oxygen.
Helium.
Sulfur.
Chlorine.
Explanation/Answer:
Metal atoms have only a few electrons in their outer shell whereas non-metal atoms have lots of electrons in their outer shell. This means that metals tend to react with non-metals. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal.
