Answer:
Cp= 1.005 kJ/kg °C = 1.005 kJ/(kg*K) = 1.005 J/g°C = 4.206 J/g°C = 0.776 BTU/lb°F
Explanation:
for the specific heat
1) Cp= 1.005 kJ/kg °C * (1 °C/ 1 K) (temperature differences) = 1.005 kJ/(kg*K)
2) Cp= 1.005 kJ/kg °C * (1000 J/ kJ)* (1 kg/1000 gr) = 1.005 J/g°C
3) Cp= 1.005 kJ/kg °C * (4.186 kcal/kJ) = 4.206 J/g°C
4) Cp= 1.005 kJ/kg °C * (1 BTU/1.055 kJ)* (0.4535 kg/lb)*(1.8°C/°F)= 0.776 BTU/lb°F

B 16g/56g x 100%
C 40g/56g x 100%
D 40g/100% x 56g
Answers
Answer:
C 40 g/56 g × 100 %
Explanation:
Calculate the mass of each component and the total mass.
Element Atomic mass/u No. of atoms Subtotal mass/u
Ca 40.08 1 40.08
O 16.00 1 16.00
Total = 56.08
The formula for mass percent is
% by mass = Mass of component/Total mass × 100 %
In this problem
% Ca = mass of Ca/mass of CaO × 100 %
% H = 40.08 g/56.08 g × 100 %
The percentage composition of calcium (Ca) in CaO is option C.
- Here we have to determine the mass of every component and even the total mass.
Element Atomic mass/u No. of atoms Subtotal mass/u
Ca 40.08 1 40.08
O 16.00 1 16.00
Total = 56.08
- The mass percent formula is
Therefore, we can conclude that the correct option is C.

FALSE
Answers
Answer:
True
Explanation:
The boiling point of a liquid is the temperature at which the vapour pressure of the liquid equals the pressure of the surrounding atmosphere.
When a liquid is heated, the vapour pressure gradually increases till it matches the ambient pressure. Gas bubbles begin to form within the liquid, rise to the surface and then burst up to release gas. At this point, we say the liquid is boiling.
The lower the surrounding pressure, the lower the boiling point of a liquid and vice versa. Water boils at lower temperature in high altitudes because of lower pressure as compared to sea level.
Correct option: True.
Reactant A contains 85.1 J of chemical energy. Reactant B contains 87.9 J of chemical energy. Product C contains 38.7 J of chemical energy. If the reaction absorbs 104.3 J of chemical energy as it proceeds, how much chemical energy must product D contain? Explain your answer.
Answers
Answer: 238.6 J
Explanation:
According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only be transformed from one form to another.
Endothermic reactions are those in which heat is absorbed by the system and thus the energy of products is higher than the energy of reactants.
For the given reaction:
Energy of A = 85.1 J
Energy of B = 87.9 J
Energy on reactant side = Energy of A + Energy of B + Energy absorbed 85.1 + 87.9 + 104.3 = 277.3 J
Energy on reactant side = Energy on product side = 277.3 J
Energy on product side = Energy of C + Energy of D
277.3 J = 38.7 J + Energy of D
Energy of D = 238.6 J
Thus chemical energy product D must contain is 238.6 J
The law of conservation of energy states that energy is not created or destroyed during chemical reactions. The total amount of energy in the reactants, plus the energy absorbed during the reaction, must be equal to the total energy of the products.
Product D contains (85.1 J + 87.9 J + 104.3 J) – 38.7 J = 238.6 J of chemical energy.
