.
Explanation:
It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.
So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of
then it known as standard state of substance.
Thus, we can conclude that standard state refers to 1 atm and
.
Some minerals tend to look alike.
Given :
A 10.99 g sample of NaBr contains 22.34% Na by mass.
To Find :
How many grams of sodium does a 9.77g sample of sodium bromine contain.
Solution :
By law of constant composition , in any given chemical compound, the elements always combine in the same proportion with each other.
Therefore , percentage of Na by mass in NaBr will be same for every amount .
Percentage of Na in 9.77 g NaBr is 22.34 % too .
Gram of Na =
.
Hence , this is the required solution .
Answer:
40/220 ×100=18.6 is all I got I know that by heart so um yea
Explanation:
I believe that the answer you have that best answers the question would be a compound. Because mayonnaise are not an element on the periodic table, and not a colloids.
