Answer: The temperature rise is 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water = 
Initial temperature = 
Final temperature = 
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is
Hey there!
Na is sodium, which has 11 protons.
The more realistic amount of neutrons for this atom to have is 12. 23 would be the sum of protons and electrons.
The atom has a charge of 1+, so there is one less electron than protons, so
11 - 1 = 10 electrons.
Your answer is d. it has 11 protons, 10 electrons, and 12 neutrons.
Hope this helps!
In order to determine the limiting reactant, we need to obtain the number of moles of each reactant and dividing this value with the stoichiometric coefficient of the reactant. The lowest value would pertain to the limiting reactant.
For S (32 g/mol)
number of moles of S = 5/32 = 0.15625
divide by the stoichiometric coefficient,1 = 0.15625
For H2SO4
number of moles of H2SO4 = 0.0510
divide by the stoichiometric coefficient,2 = 0.02551
Therefore the limiting reactant is H2SO4
Mass of each product when limiting reactant is fully consumed
mass of SO2 = 0.0510 mol H2SO4 * (3 mol SO2/ 2 mol H2SO4) * (64 g SO2/ 1mol SO2) = 4.896 g
mass of H2O = 0.0510 mol H2SO4 * (2 mol H2O/ 2 mol H2SO4) * (18 g H2O/ 1 mol H2O) = 0.918 g H2O
