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
Molecular formula of ascorbic acid is
Molar mass of ascorbic acid =
Converting 500.0 mg of ascorbic acid to moles: We use molar mass of ascorbic acid to convert mass to moles.
Converting 500.0 mg of ascorbic acid to molecules: The conversion factor used is 1 mole =
The most probable answer is: (a) <span>The black pot emits heat at a faster rate than the silver pot. It means the black pot conducts heat at a higher rate than the silver pot, that's why it cooled off faster. It also means that the silver pot retains heat better and is more of an insulator.</span>
Molarity=(initial molarityxinitial volume)/final volume
M=(3.5x25.4)/166.7=0.533 M
