Answer:
The answer is "From Chemical to Mechanical.".
Explanation:
In this question, chemical energy is an organic compound that includes contains energy from certain chains for the exergonic responses that happen when fuels emitters inside the form of heat throughout a chemical process, in which the skin converts the chemical energy in food into mechanical energy and heat.
Answer:
The mole fractions:
Explanation:
The reaction described is:
The limiting reactant is the HBr (oxygen is in excess).
a) The mass (in moles) balance for this sistem:
(the 0.78 is because of the fractional conversion)
(the 1.25 is because of the oxygen excess)
There is only one degree of freedom in this sistem, you can either deffine the moles of HBr you have or the moles of Br2 you want to produce. The other variables are all linked by the equations above.
b) Base of calculation 100 mol of HBr:
The mole fractions:
Equation: M1V1 = M2V2
Where M = concentration & V = volume
Step 1: Write down what is given and what you are trying to find
Given: M1 = 6.00M, V1 = 2.49mL, and V2 = 50.0mL
Find: M2
Step 2: Plug in the values into the equation
M1V1 = M2V2
(6.00M)(2.49mL) = (M2)(50.0mL)
Step 3: Isolate the variable (Divide both sides by 50.0mL so M2 is by itself)
(6.00M)(2.49mL) / (50.0mL) = M2
Answer: M2 = 0.30M
*Don't forget sig figs & units!
The answer is D or 4,3,2!
