Answer: 51.4 g of NaClO will be produced.
Explanation:
To calculate the moles :
According to stoichiometry :
1 moles of require = 2 moles of
Thus 0.69 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 1 mole of
Thus 0.69 moles of give = of
Mass of
Thus 51.4 g of NaClO will be produced
No <span>it can not the absolute energy states of the reactants (E1) and products (E2) be measured in a chemical reaction
hope it helps</span>
Answer:
2 hydrogen and 1 oxygen
Explanation:
H2O
Hydrogen has the coefficient so you multiply 1 by 2 and it equals 2
Oxygen does not have any sub or coe so its automatically 1
Answer:
Oil has the smaller heat capacity. The effectiveness of the heat exchanger is 0.80.
Explanation:
Part 1:
In order to know which fluid has the smaller heat capacity we need to consider the heat equation below:
Q = CΔT, where Q is the heat exchanged, C is the heat capacity and ΔT is the variation in temperature.
As the heat exchange is the same for both fluids, the smaller the temperature variation, the smaller the heat capacity.
Water: ΔT = 120 °F
Oil: ΔT = 80 °F
Therefore, oil is the fluid with the smallest heat capacity.
Part 2:
The effectiveness of a counter-flow heat exchanger is given by the equation bellow:
Th1: initial temperature of the hot fluid
Th2: final temperature of the hot
Tc1: initial temperature of the cold fluid
First you should find no of mole.
a mole is a measurement of the number of number of grams in which there are 6.02 x 10^23 atoms/molecules of a substance.
1.468 moles of NH3 in 25 grams.
(25/17.0306) 1.468 x (6.02 x 10^23) = 8.837 x 10^23 molecules.
hope this help
