Answer:
c = 0.25 j/g.°C
Explanation:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
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
Given data:
Mass of metal = 50.0 g
Heat needed = 314 j
Initial temperature = 25°C
Final temperature = 50 °C
Specific heat = ?
Solution:
ΔT = 50 °C - 25°C = 25°C
Q = m.c. ΔT
c = Q / m. ΔT
c = 314 j / 50.0 g . 25°C
c = 314 j / 1250 g. °C
c = 0.25 j/g.°C
Answer : The number of moles of 
formed are, 0.69 moles.
Explanation : Given,
Moles of 
= 0.345 mol
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction, we conclude that
As, 1 mole of react to give 2 moles of
So, 0.345 mole of react to give 
mole of
Therefore, the number of moles of formed are, 0.69 moles.
Sharks exhibit a great diversity in their reproductive modes. There are oviparous (egg-laying) species and viv
Answer:
the Answer is the second one
Explanation:
mole=mass/molar mass
mole=?
molar mass=142.1g/mole
mass=10.0g
Answer = 23.2146762081 pounds.
