You’d need to mix over have the mass of the 450 gram solution
Answer:
Bond angle is defined as the angle between two or more bonds or bonded electron pairs in a compound.
Explanation:
a) O−O−O angle of O3 - <120°
b) F−B−F angle of BF3 - 120°
c) F−O−F angle of OF2 - <109.5
d) Cl−Be−Cl angle of BeCl2 - 180°
e) F−P−F angle of PF3 - 109.5°
f) Cl−Si−Cl angle of SiCl4 - 90°
This chemical reaction can also be written as
2C2H6+7O2-->4CO2+6H2O
This is a chemical reaction because reactants are converted into products. This is the combustion of ethane where ethane and oxygen have been converted into carbon dioxide and water
Answer: 5.4
Explanation: The Law of Impenetrability says that two objects can't occupy the same space at the same time; therefore, the pennies and the water can't occupy the same space at the same time. Without the pennies the water level read 20.6 mL, dropping in the pennies gives a level of 26.0.
The Period Table of Elements has more elements that have been discovered since Mendeleyev's time.
In the modern table the elements are arranged with increasing atomic number. In Mendeleyev's table, they were arranged with increasing atomic weight.
