Answer:
carbohydrates are simple sugars which can be broken down to form 3 sugars.
which are , (maltose) (fructose) & (glucose)
Answer:
P=atm
Explanation:
The problem give you the Van Der Waals equation:
First we are going to solve for P:
Then you should know all the units of each term of the equation, that is:
where atm=atmosphere, L=litters, K=kelvin
Now, you should replace the units in the equation for each value:
Then you should multiply and eliminate the same units which they are dividing each other (Please see the photo below), so you have:
Then operate the fraction subtraction:
P=
And finally you can find the answer:
P=atm
Now solving for b:
Replacing units:
Multiplying and dividing units,(please see the second photo below), we have:
I’m almost positive the answer would be B. Electron promotion is when an electron “jumps” from a low energy level to a higher energy level.
Hope this helps!! (:
Answer : The specific heat of the metal is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water =
= mass of metal = 75 g
= mass of water =
= final temperature of mixture =
= initial temperature of metal =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the specific heat of the metal is,
