I prefer using the slope formula because it’s easy to pick two numbers on a graph and solve for the slope with a simple equation.
Answer:
Explanation:
Option A is correct .. reactants bond breaks and form new bonds to form product
Answer: 1.47
Explanation:
The combined gas equation when pressure is constant:

where,
=original number of moles of air in the balloon = ?
= number of moles of air in the heated balloon = ?
= initial volume of gas = 
= final volume of gas = 
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get the final pressure of gas.


Therefore, the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon is 1.47
Answer:
"Freezing point and ability to react with oxygen" are chemical properties
Explanation:
The change of liquid into solid is the freezing point. The melting point is more than the freezing point in certain cases of mixtures for certain organic compounds like fats. As soon as the mixture freezes it becomes solid and which results in change in the composition from the liquid and solid in this way the it drastically reduces the freezing point. The melting point gets higher due to the pressure. This happens due to the release of heat of which results in the rise of temperature to the freezing point
.Also the reaction of elements with oxygen which leads to formation of new substance is also an chemical property
Hard question thx for the points give me brainlest points plz
