Answer: he gave him a map of somewhere
Explanation:
Answer:
The answer is
<h2>0.24 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of cork = 2.88 g
volume = 12 mL
The density is
We have the final answer as
0.24 g/mL
Hope this helps you
Number 18 is correct, number 19 is the particles speed up and the substance expands, and number 20 is decrease in volume
Answer:
Specific heat of substance = 0.897 J/g.°C
Explanation:
Given data:
Specific heat of substance = ?
Mass of substance = 25.0 g
Heat absorbed = 493.4 J
Initial temperature = 12.0 °C
Final temperature = 34°C
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 = 34°C -12.0°C
ΔT = 22°C
493.4 J = 25 g ×c× 22°C
493.4 J = 550 g.°C ×c
c = 493.4 J / 550 g.°C
c = 0.897 J/g.°C
Answer:
will be not soluble in water
Explanation:
LiOH is a strong base. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a strong electrolyte. Hence it gets completely dissociated in aqueous solution.
is a sparingly soluble salt. Hence it is not dissociated and hence dissolved in water. This is due to the fact that both 
and 
ions are similar in size. Hence crystal structure of is quite stable. Hence is reluctant to undergo any dissociation in aqueous solution.
