Answer:
1 × 10^10 years
Explanation:
The current distance of the Moon from the Earth = 400,000 km
Every year, the Moon moves: 40 millimeters away from the Earth
From the question:
1 millimeter = 1 x 10^-6 kilometers
40 millimeters =
= 40 ×1 × 10^-6km
= 4 × 10^-5km
= 0.00004km
In approximately how many years will the moon be twice as far from the Earth as it is now, assuming that nothing else changes?
Twice as far = 400,000km × 2
= 800,000km
0.00004km = 1 year
400000km =
= 400,000km/0.00004km
= 10000000000years
= 1 × 10^10 years
First we need to find the limiting reactant. This is the reactant that is theoretically consumed completely first. Theoretical yield is how much product is produced given the limiting reactant is consumed and the percent yield is the fraction of the actual products produced and the theoretical products produced.
The limiting reactant is <span>Pb(<span>C2</span><span>H3</span><span>O2</span><span>)2.
The theoretical yield is </span></span>1.2373008g and you should get the Percent yield which is Actual yield/theoretical yield. <span />
