Density = 0.70 g/mL
Mass = 80.0 g
Volume = ?
V = m / D
V = 80.0 / 0.70
V = 114.28 mL
hope this helps!
Answer:
7.92 .g . mL^-1
Explanation:
Data provided in the question
Water liters = 45.5 mL
Pace of iron = 28.5 gram
Rise in the water in the cylinder = 49.1 mark
So by considering the above information
As we know that

where,
Mass = 28.5 gram
Volume = 49.1 - 45.5
= 3.6 mL
So, the density is

= 7.92 .g . mL^-1
Basically we use the density formula by dividing the mass with the volume
Answer:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change

H2=Hydrogen is the answer to what is H2 in chemistry.
Answer:
it is a chemical reaction in which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.
