Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.

Answer:
Climate change will make plants—and us—thirstier. The combined effects of increased CO2 levels and warmer temperatures will increase water consumption by vegetation. That will lead to water declines in streams and rivers like the Ashepoo River in South Carolina

Answer:
0.1 liters of NaOH.
Explanation:
When the acid solution is neutralized we have:
Where:
: is the number of moles of the acid
: is the number of moles of the base
: is the concentration of the acid
: is the concentration of the base = 0.1 M
: is the volume of the acid = 10000 L
: is the volume of the base =?
The concentration of the acid can be calculated from the pH:
![pH = -log([H^{+}])](https://tex.z-dn.net/?f=%20pH%20%3D%20-log%28%5BH%5E%7B%2B%7D%5D%29%20)
![[H^{+}] = 10^{-pH} = 10^{-6} M](https://tex.z-dn.net/?f=%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D%20%3D%2010%5E%7B-6%7D%20M%20)
Now, we can find the volume of the base:
Therefore, the amount of NaOH needed to neutralize the solution is 0.1 liters.

Answer:
An alcohol thermometer can easily measure the boiling point of a colorless liquid that boils at 100 °C.
A mercury thermometer can easily measure the boiling point of a colorless liquid that boils at 82 °C.
A mercury thermometer can easily measure the freezing point of a colorless liquid that freezes at −50 °C.
or An alcohol thermometer can easily measure the freezing point of a colorless liquid that freezes at −110 °C.

Standard Temperature and Pressure (STP) is 0 degree Celsius and 1 atm. We also know that 1atm= 101.3 kPa. Thus, set 3 is the best choice.
Hope that would help :))
