Answer:
The volume of the rock is 2 mL
Explanation:
The level to which the graduated cylinder is filled with water by Abby = 3 mL
The level to which the graduated cylinder after the rock is dropped in = 5 mL
Therefore;
The volume of the rock = The level to which the graduated cylinder after the rock is dropped in - The level to which the graduated cylinder is filled with water by Abby
The volume of the rock = 5 mL - 3 mL = 2 mL
The volume of the rock = 2 mL.
linguistic and sociolinguistic should be your answer.
Answer:
<u>D) A base.</u>
Explanation:
A base in chemistry is something that is slippery, hence it being a soap.
Dry, white powder, soluble in water to form a slightly basic solution
Answer:
Specific heat capacity = 0.24 j/g.°C
Explanation:
Given data:
Mass of metal = 82.4 g
Heat absorbed = 846 j
Change in temperature = 67°C - 25°C
Specific heat capacity = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 67°C - 25°C
ΔT = 42°C
Q = m.c. ΔT
846 j = 82.4 g . c. 42°C
c = 846 j / 3460.8 g.°C
c = 0.24 j/g.°C
