<span><span>N2</span><span>O5</span></span>
Explanation!
When given %, assume you have 100 g of the substance. Find moles, divide by lowest count. In this case you'll end up with
<span><span>25.92 g N<span>14.01 g N/mol N</span></span>=1.850 mol N</span>
<span><span>74.07 g O<span>16.00 g O/mol O</span></span>=4.629 mol O</span>
The ratio between these is <span>2.502 mol O/mol N</span>, which corresponds closely with <span><span>N2</span><span>O5</span></span>.
Answer:
1/4th
Explanation:
KE = .5mv^2
So when we decrease the velocity by half, we end up losing three fourths of net energy due to that value being squared.
The Calvin Cycle is the process that will be the last one to be affected by shorter periods of daylight. Carbon dioxide goes in the interior of a leaf through pores of plants, which is called stomata and spreads into the stroma of the chloroplast this is the site of the Calvin cycle reactions, wherein sugar is produced and synthesized. These reactions are also called the light-independent reactions because they are not directly driven by light.
When comparing the reactivity of aluminum or magnesium to the reactivity of silver, we will find that both aluminum and magnesium are more reactive than silver.
Therefore, magnesium or aluminum can both replace the silver in the silver sulphide.
That's why <span>a piece of aluminum or magnesium can be used to remove tarnish, which is mostly silver sulfide, on silverware.</span>
