Answer:
Final temperature = 
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .

Answer:
a. Dipole-dipole bonding
Explanation:
SO2 has dipole-dipole bonding. This is because of the difference in the electronegativities of Sulphur and oxygen. Moreover, the lone pair of electrons on S gives it bent shape with a net dipole unlike CO2 which has a linear shape.( This why CO2 does not have any dipole moment).
So, the correct answer is a.
Answer:
6792.1 g
Explanation:
Dimensional analysis:
376.92 mol H2 * (2 mol h2o / 2 mol h2) * (18.02g h2o / 1 mol h2o)
6792.1 g
They are called guard rails
