Answer:
mass- the amount of matter in an object
balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
Answer:a
Explanation:
Given
![[H^+]=5.3\times 10^{-4}\ M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D5.3%5Ctimes%2010%5E%7B-4%7D%5C%20M)
and 
Also ![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
therefore 
Thus 
and ![pOH=-\log [OH^{-}]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E%7B-%7D%5D)
![[OH]^{-1}=10^{-10.25}](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D10%5E%7B-10.25%7D)
![[OH]^{-1}=1.88\times 10^{-11}\ M](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D1.88%5Ctimes%2010%5E%7B-11%7D%5C%20M)
As the pH is less than 7 therefore solution is acidic
That statement is <em>false</em>.
"Condense" is what a gas does when it turns into liquid, and that's something that happens when the gas is cooled, not heated.
Answer:
MASS is measured in KILOGRAMS
Weight is measured in NEWTONS
Explanation:
Answer: it is better to use renewable energy. Some of the benefits are: The main advantage is the practically zero emission of greenhouse gases (GHG) and other pollutants that affect climate change.
They help decrease pollution-related illnesses.
It does not need large amounts of water for its operation.
