Answer:
false
Explanation:
Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. ... Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and elec
Ni(s) + CuSO₄(aq) → Cu(s) + NiSO₄(aq)
Ni + Cu²⁺ + SO₄²⁻ → Cu + Ni²⁺ + SO₄²⁻
Ni + Cu²⁺ → Cu + Ni²⁺

2.3 M is the molarity of a solution that contains 2.3 moles of solute in 1.0 liter of solution.
Explanation:
Data given:
volume of the solution = 1 litre
number of moles of the solute = 2.3 moles
Molarity of a solution is given by number of moles of a given solute in a given volume in litres.
The unit of molarity = moles/litre
The formula used to calculate molarity is given by:
molarity =
Putting the values in the equation,
molarity =
molarity = 2.3
Thus the molarity of the given solution is 2.3 moles/litre.
The molarity of the solution is also written as 2.3 M.
Answer:
Scientists consider human to be" carbon creatures" because carbon atoms form the backbone or foundation of pretty much the essential biological molecules floating around in our bodies (except water, of course.) All in all, scientists can consider humans to be " carbon creatures" because our skin, hair and cells are all made out of molecules that contain huge amounts of carbon.
Hope this helps! God bless!
