Explanation:
1. 2,3-dimethylhexane
2. 2,4-dimethylhexane
3. 2,5-dimethylhexane
4. 3,4-dimethylhexane
Below are the structures of the isomers.
Matter is the basic unit of all things in the world, whether living or nonliving. It is not only useful in chemistry, but also to other fields of science like physics. Physics deals with motion, so it has something to do with matte especially the movement of molecules for solids and fluids.
Answer:
Aluminum oxide
Explanation:
Just answered and was right
Answer:
2.00 M
Explanation:
The formula mass of aluminum oxide is 2(27)+3(16)=102 g/mol.
So, there is 1 mole of solute in 500 mL=0.5 L of solution
Now, we can use the equation molarity = (moles of solute)/(liters of solution)
- molarity = 1/0.5 = <u>2.00</u><u> </u><u>M</u>
2moles
1.20moles
0.5mole
Explanation:
Given parameters:
Mass of He = 8g
Mass of Zn = 78g
Volume of oxygen gas= 11.2L
Unknown:
Number of moles of He, Zn = ?
Number of moles of oxygen gas = ?
Solution;
Number of moles of substances is given as :
Number of moles =
molar mass of He = 4g/mol
molar mass of Zn = 65.4g/mol
Number of moles of He = = 2moles
Number of moles of Zn = 1.20moles
For gases at STP;
Number of moles =
Number of moles = = 0.5mole
