Answer:
the heat exchange between the system and the surrounding medium
Explanation:
The first law of thermodynamics states that: "Energy can neither be created nor destroyed, but can convert from one form to another"
It is represented mathematically as:
<span>Δ e=q-w
where:</span>
<span>Δ e is the total change in the system's internal energy
q is </span><span>the heat exchange between the system and the surrounding medium
w is the work done either on the system or by the system
Hope this helps :)

1747.2 ml of HNO3 is required to reach methyl orange endpoint.
Explanation:
Number of moles of NaOH solution having 17.5 gram NaOH in 350ml of water.
Atomic weight of NaOH = 40 g/mol
thus number of moles= 17.5/40
= 0.437 moles
Now the molarity of the solution is calculated as
M=n/C
= 0.437/O.35 LITRES
= 1.248 M solution of the base
the molarity of acid is given as 0.25 M of HNO3
From the formula
M1V1=M2V2 we can calculate the volume of HNO3 required to make solution acidic.
1.248*350= 0.25*v2
v2= 1.248*350/0.25
= 1747.2 ml
Thus 1747.2 ml of HNO3 is required.
Answer:

Answer:
84.27 g
Explanation:
<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>
Step 1: Calculate the moles of atoms of hydrogen
The molar ratio of C₃H₈ to H is 1:8.
10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H
Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen
The molar mass of hydrogen is 1.008 g/mol.
83.60 mol × 1.008 g/mol = 84.27 g
