87.07 torr
Explanation:
n:7.7059 g-5.9203 g= 1.7856 g
Molar mass of benzene = 78.11g/mol
n=1.7856 g /78.11g/mol= 0.023 mol
T= 273 + 28 = 301 K
PV=nRT.
Weget
P=nRT/V
P=(0.023 mol x 8.3 J/molK x 301 K) / 0.00495m3= 11608. 3Pa= 87. 07 Torr
Answer: 87. 07 Torr
OK,lisen to me slowly,
all define you.all thing
1.Look at peridoic table which one is solid or others.
For example:hydrogen is air.
And you gonna explain what is hydrogen,
2.After look periodic table you will be able to know every element.
3.Dont forget to check your homework.!!
Answer:
Explanation:
Naming of the ionic compounds:-
- The name of the cation is written first and the the name of the anion is written after the name of the cation separated by single space.
- The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
-
In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.
Hence, given ionic compound:-
Cobalt(II) phosphate
So, Cobalt will have a positive charge of +2
Phosphate is
So, the formula is :-
Co
2 3
It is one of the end products of cellular respiration that is generated during the electron transport stage.
I hope this helps. <span />
