Answer:
Oxygen
Explanation:
If two balloons are filled with hydrogen gas and helium gas respectively, then we want to identify what gas is in each balloon, we have to do so by exposing the both balloons to flame in an oxygen atmosphere.
Hydrogen combines with oxygen in the presence of a flame with quite a loud sound and the flame is sustained but when a flame is brought near helium gas in a balloon, the gas will only make a little sound when exposed to the flame and extinguish the flame.
The reason for the explosion of the gas in the hydrogen balloon is that combustion of hydrogen gas is exothermic. The heating up of surrounding air molecules leads to a sudden explosion.
However, the helium balloon makes a little sound when the balloon is ruptured releasing helium gas which extinguishes the flame.
It would be weathering because of all the heat and pressure.
THE ANSWER IS: <u>737.5</u>
I JUST TOOK THE QUIZ!!!!
the answer is c, more heat is being released.
When water turns to steam,
D) the water absorbs energy which causes the water molecules to have more kinetic and potential energy changing their configuration from a liquid to a gas.
Hope this helps! :)
