Explanation:
If the resources run out and there is no way to get them all motors will have to be switched to solar or some other source.
Brainliest please!!!!!
Let our basis for answering this item be 1 mol of the given substance. Then, we calculate for the equivalent mass by multiplying the number of moles with the molar mass.
mass = (102.13 g/mol)(1 mol) = 102.13 g of substance
Then, we calculate for the amount of sulfur and fluorine each using the percentage given.
sulfur = (0.6279)(102.13 g) = 64.13 g of sulfur
fluorine = (1 - 0.6279)(102.13 g) = 38 g of fluorine
Then, calculate for the number of moles of the sulfur and fluorine by dividing the calculated mass by the molar mass of each.
moles of sulfur = (64.13 g)(1 mol/32 g) = 2 mols suflur
moles of fluorine = (38 g)(1 mol/19 g) = 2 mols fluorine
The molecular formula of the substance is S₂F₂.
<em>ANSWER: S₂F₂</em>
A proton<span> is one of the most </span>important<span> types of subatomic particles. </span>Protons <span>combine with electrons and neutrons to </span>make<span> atoms. </span>Protons<span> are nearly the same size as neutrons and are much larger than electrons. ... </span>Protons<span> are composed of two up quarks and one down quark.......Hope this helps can you mark me brainliest?</span>
Answer:
A collapse of the population is rotting, food is not enough and livelihoods have become unfeasible to decrease the number of individuals again.
Another way is to generate mutations to generate a species more vulnerable to decreasing numbers.
In this way the overpopulation is controlled.
Explanation:
In ecosystems, if an increased population breaks the balance of this and begins a new constant adaptation of the extinction of some and overpopulation of others, which may be some chains break or remain unstable.
