The combustion reaction of acetylene has a balanced equation
C2H2+3O2--->2H2O+2CO2
Using the ratio 1:3:2:2, if 1.10 mols of CO2 are produced, assuming complete combustion, than that means that 0.55 mols of acetylene (C2H2) must have been combusted. The molar mass of acetylene is 26, so the answer is 26*0.55 = 14.3 grams
BPA, or bisphenol A, is in most plastics and it is toxic to humans because it can bind to the estrogen hormone and greatly alter your body's natural functions from there. It can also bind to your thyroid hormone.
Answer:
1x10^-3M
Explanation:
Data obtained from the question include:
pH = 3
[H3O+] =?
The concentration of the hydronium ion [H3O+] can be obtained by using the formula pH = - Log [H3O+] as illustrated below:
pH = - Log [H3O+]
3 = - Log [H3O+]
Divide through by - 1
- 3 = Log [H3O+]
Take the anti-log of - 3
[H3O+] = 1x10^-3M
Therefore, the concentration of the hydronium ion [H3O+] is 1x10^-3M
An ionic compound consists of a metal AND a non-metal.
<em>Option A:</em>
Oxygen and fluorine are non-metals.
<em>Option B:</em>
Sodium and aluminium are non-metals.
<em>Option C:</em>
Calcium is a metal and chlorine is a non-metal.
<em>Option D:</em>
Nitrogen and sulfur are non-metals.
Thus, the answer is C.
