Allotropes are elements on the periodic table that have more than one crystalline form . There are three forms of the element carbon : Diamond, Graphite, and Fullerenes. Isotopes are atoms of the same element with the same atomic number but have a different mass number.

Ok so the gravitational force the moon exerts on earth is very small. The ocean, however, is affected by it. How gravity works (in a simplistic sense) is that, when you are closer to something, the force is stronger. So, when the moon is close to Earth (at Perigee) the force of gravity is stronger. So the moon pulls the water more towards itself. This results in higher waves occurring when the moon is closer (at perigee) than at apogee.

aliina [53]

Answer:

40.3 for the unit that represents the minimum amount of magnesium oxide I beilieve.

Explanation:

Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. Taking just one atom of Mg and one atom of O you will get a mass of 16.0 + 24.3 = 40.3.

Hope this helps! Please tell me if you have any questions :))

svlad2 [7]

Answer:

n = 0.573mol

Explanation:

PV = nRT => n = PV/RT

P = 1.5atm

V = 8.56L

R = 0.08206Latm/molK

T = 0°C = 273K

n = (1.5atm)(8.56L)/(0.08206Latm/molK)(273K) = 0.573mol
