Answer: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Density = mass/volume = 16.31/8.29 = 1.96 g/mL.
Hope this helps!
Ethyl benzoate, (C9H10O2)<span>, is an </span>ester<span> formed by the condensation of </span>benzoic acid (which is a carboxylic acid)<span> and </span><span>ethanol (alcohol)
When you see a molecule named like *****yl ****ate it's probably an ester. Its name regroup the name of the carboxylic acid (which ends by "ate") and an alkyl (derivated from the alcohol)</span>
They move around more, think of it like if they jumping around because it's hot.
Answer is: 20.0g H - 20.0 moles; 0.50 g Na - 0.022 moles; 2.0 x 102 mg H2O - 0.011 moles.
1) m(H) = 20.0 g; mass of hydrogen.
n(H) = m(H) ÷ M(H).
n(H) = 20 g ÷ 1 g/mol.
n(H) = 20.0 mol; amount of hydrogen.
2) m(Na) = 0.50 g; mass of sodium.
n(Na) = m(Na) ÷ M(Na).
n(Na) = 0.5 g ÷ 22.98 g/mol.
n(Na) = 0.022 mol; amount of sodium.
3) m(H₂O) = 200 mg ÷ 1000 mg/g.
m(H₂O) = 0.20 g; mass of water.
n(H₂O) = m(H₂O) ÷ M(H₂O).
n(H₂O) = 0.2 g ÷ 18 g/mol.
n(H₂O) = 0.011 mol; amount of water.
