Answer:
A. Offspring are genetically identical to the parent.
That's the answer. I hope it helps!
Answer:
To find the number of neutrons we would subtract the number of protons from mass number of an atom.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example:
The mass number of carbon is 12 amu and it has six protons thus to find the number of neutrons we would subtract the 6 from 12 and get number of neutrons.
12- 6 = 6 neutrons
Answer:A metal can only displace another metal from a compound if it is located above it in the reactivity series. A displacement reaction happens when a more reactive metal (one that forms positive ions more easily) displaces a less reactive metal from a compound.
Explanation:
Answer: The coefficient for is 12.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 12 molecules of oxygen in balanced chemical equation. Thus the coefficient for is 12.
Answer:
tend to form ionic bonds by losing electrons making these atoms positive charge.
