Answer:
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:
Explanation:
Step 1: Carbon and oxygen react to form carbon monoxide:
..[1]
Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:
..[2]
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :
3 × [1] + 2 × [2]
CO gas will gas cancel out form both sides ans we will get the net chemical equation:
According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.
Answer:
D. 1.0 x 10-8.43
Explanation:
The pH is an unit of concentration in chemistry used to determine the acidity -or basicity- of a particular solution. Is used in quality control to determine the security of a product for consumers.
The equation is:
pH = -log [H₃O⁺]
As pH = 8.43:
8.43 = -log [H₃O⁺]
10^-8.43 = [H₃O⁺]
1.0x10 -8.43 = [H₃O⁺]
Right option is:
<h3>D. 1.0 x 10-8.43
</h3>

Answer:Well There is many ways to increase friction between objects. One being rubbing the two objects together quicker and harder. If there is any sort of wetness or anything related to that make sure to dry the surface between the two objects you want to create friction between so it will be more effective.
