Answer:
3284.3 kg is the mass of HCl needed to produce 5000 kg of CaCl₂
Explanation:
This is the reaction:
CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O
Let's convert the mass of the product to moles (mass (g) / molar mas)
Firstly we must convert kg to g
1 kg = 1000 g
5×10³ kg . 1000 g / 1 kg = 5×10⁶ g
5×10⁶ g / 110.98 g/mol = 45053.1 moles
Ratio is 1:2 So, let's make a rule of three:
1 mol of CaCl₂ was produced by the use of 2 moles of HCl
So 45053.1 moles of salt, were produced by, the double of moles
45053.1 mol . 2 → 90106.2 moles
Let's convert the moles, to mass (mol . molar mass)
90106.2 mol . 36.45 g/mol = 3284375 g → 3284.3 kg
The layer of Earth’s atmosphere that has the coldest temperature range is mesosphere
In the sun, two hydrogen nuclides react together to make an atom of helium. the process releases energy. This is nuclear fusion reaction. The Sun uses this reaction to release energy and heat.<span> Hydrogen nuclei fuse together to form helium nuclei and release energy. The formula that describes this reaction is the following: 1/1H+1/1H->3/2He</span>
<span>The
metallic properties that are caused by atoms rolling over each other in
metallic bonds are malleability and ductility.the atoms that are being rolled
over are delocalized electrons in the sea of electrons in the metallic bond
enable them to roll over when stress is applied.</span>
