Answer:
So the molar mass of C4,H10 is
58.12g mole -1
Answer;
The above statement is true
upon heating a copper sample will expand, leading to a lower density
Explanation;
-The density of solids decreased with increase in temperature and vice versa. The increase in temperature causes the volume of the solid to increase which as a result decreases the density as Density=Mass/Volume. The temperature of a body is the average kinetic energy of the molecules present in it.
In other words; The temperature of a body is the average kinetic energy of the molecules present in it. Therefore; when heat is supplied ( or temperature is increased) the average kinetic energy increases which increases the volume and thus density decreases.
ºC = ( ºF - 32 ) / 1.8
ºC = 95 - 32 / 1.8
ºC = 63 / 1.8
= 35 ºC

Answer:
B. 16
Explanation:
Cl -35 and Cl-33 have the same number of protons because it is the same element Cl.
Their masses are different because they have different number of neutrons.
Cl- 33 has 2 neutrons less than Cl-35.
35 - 33 = 2
If Cl-35 has 18 neutrons, then Cl-33 has 18-2=16 neutrons.
