Answer:
between metal and nonmetal ions
Explanation:
We can arrange the following entities from sizes smallest to
largest in:
<span><span>
1.
</span>Carbon atom. Consider the
carbon atom in the periodic table which evidently small in size. Like any other
atom such as hydrogen and oxygen.</span>
<span><span>
2.
</span>Monomer. Is a singular molecule
that can combine itself with elongated chains and other molecules. And thus form,</span>
<span><span>3.
</span>Polymer. Polymers are
made from a complex amalgamation of monomers.</span>
<span><span>4.
</span>Macromolecule. And thus
the macromolecules from the word macro are the biggest component. Which forms the
lipid, proteins, RNA enzymes in the cell. <span>

Answer:
1.
2.
Explanation:
1.Momentum is given as the product of mass by velocity of an object.
Momentum,
m=1,500kh, v=6m/s
2.Momentum,
m=7800kg, v=30m/s
new mass=7800+800=8600
As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.
Answer:
Empirical formula is CH₄
Molecular formula = C₂H₈
Explanation:
Mass of carbon = 37.5 g
Mass of hydrogen = 12.5 g
Molecular weight = 32 g/mol
Molecular formula = ?
Empirical formula = ?
Solution:
Number of gram atoms of C = 37.5 g /12g/mol = 3.125
Number of gram atoms of H = 12.5 g / 1.008 g/mol= 12.4
Atomic ratio:
C : H
3.125/3.125 : 12.4 /3.125
1 : 4
C : H : = 1 : 4
Empirical formula is CH₄
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 32 / 16
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 ( CH₄)
Molecular formula = C₂H₈
