Answer:
The correct answer is C.
Explanation:
To solve this problem, we should first recall possible units for mass and volume. Mass can be represented with units of grams, kilograms, etc. Volume has units of cubic meters, cubic centimeters, etc.
Therefore, since we know that density is mass divided by volume, the only answer that makes sense here is C. grams per cubic centimeter (where per signifies that grams are being divided by cubic centimeters).
Hope this helps!
Say the dereference between the two is that "Exo" means "outside" and "Endo" means "inside" meaning one pulls heat inside (endothermic) and the other expels heat (exothermic)
Answer:
The answer to your question is below
Explanation:
A qualitative property of matter is a property characteristic of a substance like color and flavor.
A quantitative property of matter is a property when we get a number.
A) it's a circular shape is a qualitative property because the shape is a qualitative property and shape is not represented by a number.
B) its mass is 1.5 kg is a quantitative property because we know a number of this mass.
C) it tastes like chocolate is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.
D) it is 30 cm in diameter it is a quantitative property, we know the exact dimension of it.
E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.
Answer:
atomic mass 112.4 and Cadmium (Cd)
Explanation:
You have 73.35 g of MO.
After the reaction the O is removed and you only have M which the mass is 64.21 g.
With that you can calculate the mass of O removed:
Mass of O = 9.14 g
Mass = AM * moles ; (AM : Atomic Mass)
9.14 = 16 * moles
moles = 9.14 / 16
moles = 0.57125
The formula of the metal oxide is MO, meaning it has 1 mole of M per mole of O. 73.35 had 0.57125 moles of O, then it also had 0.57125 moles of M, and the remaining mass of 64.21 g represents those moles
Mass = AM * moles ; (AM : Atomic Mass)
64.21 = AM * 0.57125
AM = 64.21/0.57125 = 112.4 amu
The metal with an atomic mass of 112.4 is Cadmium (Cd), therefore the metal oxide is CdO
Answer:
Hydrogen bonding is the major intermolecular attraction responsible for the relatively high boiling points of alcohols.
