Given:
1 mole of compound synthesized from its elements
Temperature of the substances in their standard states = 25 degrees Celcius
First, gather data from reference books on the standard heats of formation of the elements. Then set up a balanced equation for the reaction. From there, calculate the heat of reaction.
<span>Charles' law says "at a constant pressure, the volume of a fixed amount of gas is directly proportional to its absolute temperature".
V </span>α T
Where V is the volume and T is the temperature in Kelvin of the gas. We can use this for two situations as,
V₁/T₁ = V₂/T₂
V₁ = 2.00 L
T₁ = 40.0 ⁰C = 313 K
V₂ = ?
T₂ = 30.0 ⁰C = 303 K
By applying the formula,
2.00 L / 313 K = V₂ / 303 K
V₂ = (2.00 L / 313 K) x 303 K
V₂ = 1.94 L
Hence, the volume of the balloon at 30.0 ⁰C is 1.94 L
Q = mass x specific heat x delta T 343 = 55.0 x specific heat ( 86.0 - 19.0 ) 343 = 3685 x specific heat specific heat = 0.0931 cal /g°C
Shoutout to @hihi67
Your answer is: 0.0931 cal/g degrees C
Have an amazing day and stay hopeful!

What is Metallic bond ?
- Metallic bond is a force that holds atoms together in a metallic substance.
Answer:
328 ml
Explanation:
We have given final volume =575.2 ml=0.575 L
Final concentration = 0.8012 M
We know that moles of copper(II) nitrate = final volume ×final concentration =0.8012×.0575=0.4606 moles
We have to find initial volume
So initial volume
