Answer:
atoll
Explanation: this is correct, pls give me brainliest
Actually the correct answer must be:
The limiting reactant in the reaction is the one which has
the lowest ratio of moles available
over coefficient in the balanced equation
This is because the actual mass or number of moles of the
reactant does not directly dictate if it is a limiting reactant, this must be
relative to the other reactants.
So the answer is:
e. none of the above
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
