Answer:
The volume of gold is 3.3 cm³.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m³.
Other units are given below,
g/cm³, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of gold = 63 g
Density of gold = 19.32 g/cm³
Volume of gold = ?
Solution:
d = m/v
v = m/d
v = 63 g/ 19.32 g/cm³
v = 3.3 cm³.
Answer:
Covalent compounds don't contain ions because they make bonds by sharing electrons. In addition, they don't have any charge carries that are free to move so they can't carry electric current
Explanation:
compressibility - is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. (D)
Flammability - ability of a chemical to burn or ignite, causing fire or combustion. (B)
Heat of Combustion - The amount of heat released per unit mass or unit volume of a substance when the substance is completely burned. (A)
Reactivity - the state or power of being reactive or the degree to which a thing is reactive (C)

4 moles
Explanation:
Given parameters:
number of moles of reacting NO = 24moles
Equation of the reaction:
4C₃H₆ + 6NO ⇒ 4C₃H₃N + H₂O + N₂
Solution:
The moles is synonymous the quantity of matter that contains the avogadro's number of particles.
To solve this problem, we must ensure that the given equation is balanced by simply inspecting.
The equation is balanced by inspection.
From the balanced equation;
6 moles of NO reacted to produce 1 mole of nitrogen gas
24 moles of NO will therefore produce 
= 4 moles
