Answer:
Ba^2+ (aq) +SO4^2- (aq) →BaSO4(s)
Explanation:
you really need to learn how to do this yourself - its really important throughout level chem, pre-ap chem, and especially if you plan on moving on to ap chem!!
Sunlight is a renewable perpetual resource, while oil is a nonrenewable
resource.
The balanced reaction:
<span>4Na + O2 = 2Na2O
We use the relation of the substances and the amount of sodium to determine the theoretical yield of the reaction. This yield is the amount produced if all the reactant is consumed.
2.55 mol Na (2 mol Na2O / 4 mol Na) ( 61.98 g / 1 mol ) = 79.02 g Na2O
Percent yield = 75.0 / 79.02 x 100 = 94.91%</span>
Answer:
V is proportional to StartFraction n over p EndFraction.
Explanation:
Let us remind ourselves of the statements of both Boyle's law and Avogadro's laws.
Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Avogadro's law states that at the same temperature and pressure, equal volumes of gases contain equal number of molecules.
Hence ;
V α 1/P (Boyle's law)
V α n (Avogadro's law)
V α n/p (combination of Boyle's law and Avogadro's law)
Answer:
neutron
Explanation:
neutron and proton has approximately the same mass .proton is positively charged but neutron has no charge
