The helium would expand into the air of the room. Depending on how big the room is, and the amount of helium in the jar, it could cause damage to health. The only way this would happen is if the room was small and the jar was big.
I hope this helps!
Answer : Option D) Sodium Chloride.
Explanation : Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure surrounding the liquid.
On the basis of bonding, the compound which has highest boiling point is sodium chloride.
Alcohol are found to have boiling point approximately as 78.37 °C.
Glucose usually melts at 146 °C.
Water boils at 100°C.
Sodium chloride has boiling point 1413 °C.
So, it is easy to identify that NaCl (sodium chloride) has highest boiling point amongst the given choices.
Answer:
26.8g
Explanation:
The formula of the compound given is:
Cu₂CrO₄
Given:
Number of moles = 0.11
To find the mass, we use the expression below:
Mass = number of moles x molar mass
Molar mass of Cu₂CrO₄ = 2(63.6) + 52 + 4(16) = 243.2g/mol
Now insert the parameters and solve;
Mass = 0.11 x 243.2 = 26.8g
Answer: less humidity, no precipitation and cooler temperatures
Explanation: I just did the assignment
Answer : The new volume of the balloon is, 22.4 L
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = 22.6 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above formula, we get the final volume of the gas.
Therefore, the new volume of the balloon is, 22.4 L
