Hey there!:
Mass = ?
Volume = 35.5 mL
density = 3.6 g/mL
By the definition of density :
D = m / V
3.6 = m / 35.5
m = 3.6 * 35.5
m = 127.8 g
hope this helps!
Yes; every object has energy and you cannot create or destroy energy but you can transfer it.
Explanation:
Molecular equation: Chemical equation in which molecular formula of reactants and products are written
Complete ionic equation:Chemical equation in which ionic from if reactants reactants and products are written along with spectator ions (ions present on both sides of equation).
Net ionic equation :Chemical equation in which only ions of those reactant are written which giving product without spectator ions (ions present on both sides of equation).
(a) 
net ionic equation.
(b) 
Molecular equation
(c)
Net ionic equation.
(d) 
Complete ionic equation
Answer:
88%.
Explanation:
The percentage yield of lead sulfate in this experiment is 88% if 2.53 is divided by 2.85 and multiply by 100. The percentage yield can be calculated when the experimental yield is divided by theoretical yield and then multiply by 100. The percentage yield tells us about the actual yield that is gained in the end of experiment which is lower than theoretical yield.
