Answer: 1.96x10^24 atoms
Explanation:
3.25*6.02214076*10^23 atoms = 1.96x10^24
It’s B. Substitution hope this helps
<u>Answer:</u> The unbalanced chemical equation is written below.
<u>Explanation:</u>
Unbalanced chemical equation does not follow law of conservation of mass.
In an unbalanced chemical equation, total number of individual atoms on the reactant side will not be equal to the total number of individual atoms on the product side.
The chemical equation for the reaction of diboron trioxide and magnesium metal follows:
Hence, the unbalanced chemical equation is written above.
Answer:
Here’s what I get.
Explanation:
- The atomic number is the number of protons in the nucleus of an atom.
- The number of protons determines the number of electrons.
- The number of electrons determines the chemical properties of the element,
Thus, the atomic number determines the identity of the element.
The atomic mass does not affect the chemical properties, so different isotopes of an element behave alike.
Hey mate
This is the answer
The elements potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.
Plsssssss mark me as brainliest
