Because it is extremely hot.
One electron is shared between ethane, H3-C-C-H3
Answer:
1.693 atm
Explanation:
According to Boyle's Law, an inverse relationship exists between pressure and volume. ... The relationship for Boyle's Law can be expressed as follows: P1V1 = P2V2, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change under a constant temperature and ideal behaviour
P1V1 = P2V2
P1 = 5.08
V1= 1.19L
P2=?
V2= 3.57L
P1V1 = P2V2
5.08x 1.19 = P2(3.57L)
6.0452/3.57 = P2 = 1.693 atm
It will be too high or too low, depending on whether the liquid forms a positive or negative meniscus.
The final temperature is -138 °C.
Explanation:
Using the equation of specific heat
We can easily find the final temperature of a 73.174 g of copper sample. As we know that specific heat is the amount of energy required to raise the temperature of the object to 1°C.
The specific heat of copper is known as 0.387 J/g°C and the initial temperature is said as 102 °C . The mass is given as 73.174 g. The heat released is 6800 J.
Since the heat is released the Q value will be negative.
Thus, the final temperature is -138 °C.
