Answer:
The answer is D
Explanation:
Although natural processes continually form fossil fuels, such fuels are generally classified as non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. ... The use of fossil fuels raises serious environmental concerns.

Answer:
11·699
Explanation:
Given the concentration of hydroxide ion in the solution is 5 × 
M
Assuming the temperature at which it is asked to find the pH of the solution be 298 K
<h3>At 298 K the dissociation constant of water is
</h3><h3>∴ pH + pOH = 14 at 298 K</h3><h3>pOH of the solution = -log( concentration of hydroxide ion )</h3>
∴ pOH of the given solution = - log(5 × = -0·699 + 3 = 2·301
pH of the given solution = 14 - 2·301 = 11·699
∴ pH of the solution = 11·699
Ok so all are in the alkali family also they are all metals and in group 1 but I think the one that might reacts quickest is Li because it has less AMU
Answer:
1.5 moles
Explanation:
To find the number of moles of HCl in 500 mL of a 3 M solution of HCl, we consider moles in 1 liter/ 1000 mL.
3 moles HCl is contained in 1000 mL
x moles is HCl is contained in 500 mL
Hence the number of moles of HCl in 500 mL is 1.5 moles.
Our coefficients would be:
C12H22O11: 1
O2: 12
CO2: 12
H2O: 11
Why?
With the coefficients, our reactants would be:
12 carbons, 22 hydrogens, and 35 oxygens.
To obey the law of conservation of mass, we would have to have an equal amount of each of those elements on the products side, since so much of that element needs to form an equal amount on the other side.
So, with those coefficiens, our products would be:
12 carbons total, 35 oxygens total, and 22 hydrogens total. If we compare to the reactants side, they are all equal!
And, since 1 or 11 cannot be simplifyed any smaller, we know the equation is completely balanced.
Hope I could help!
