The correct answer is option A.
D = M/V
The density of a substance is the ratio of its mass to its volume.
Density = mass / volume
or D = M/V
The unit of density is gram per milliliter or g/ml, when mass is expressed in gram or g and the volume is expressed in milliliter ml.
If we know the mass and volume of a substance we can calculate its density using the formula for density.
Answer: atoms do have 3 subatomic particles but the nucleus is positive and the nucleus consists of protons and neutrons. Its positive because neutrons have no charge and protons have a positive charge. There are only electrons on the shells so no neutrons or protons on the shells
Explanation:
Explanation:
The most reactive metals are found on the left of the periodic table, in the blue column, known as the alkali metals. Their reactivity increases as we go down column (group) one. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting.
Answer:
449.5 g
Explanation:
Silver sulfate- Ag2SO4
M(Ag)=107 g/mol => M(Ag2)=214 g/mol
M(S)=32 g/mol
M(O)=16 g/mol => M(O4)=64 g/mol
M(Ag2SO4)=310 g/mol
n=1.45 mol
m(Ag2SO4)=M(Ag2SO4)*n=310 g/mol *1.45 mol= 449.5 g
Answer:
strong nuclear force
Explanation:
1, a force that acts on charged particles
2, a force that holds atomic nuclei together
3, gravity, weak nuclear, electromagnetic, strong nuclear
4, strong nuclear force
5, Gravity and the electromagnetic force have infinite ranges while the nuclear forces have very small ranges.
100% :)
