likely be the same
Explanation:
this is because we have one color that both atoms share (green). both sample 1 and sample 2 have green and another color. yet, since they share one color, they are likely similar
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.
the answer to your question is
M1V1=M2V2
V2=750-150=600 ml
0.75M*750 ml = M2*600
M2=0.75*750/600 ≈ 9.38 M
