1.0 mg/mL
a) Convert <em>grams to milligrams
</em>
Mass = 1.0 g × (1000 mg/1 g) = 1000 mg
b) Convert <em>litres to millilitres
</em>
Volume = 1 L × (1000 mL/1 L) = 1000 mL
c) Calculate the <em>density
</em>
ρ = mass/volume = 1000 mg/1000 mL = 1.0 g/mL
Answer:
a usually reversible change in the physical properties of a substance, as size or shape
<u>For example:</u>
Freezing a liquid is a physical change.
Answer:
Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol)
Explanation:
Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol) is an organic compound with the formula (CH3)2CHCH2OH (sometimes represented as i-BuOH). Hope this helped!
A) The half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases
Explanation:
The rate at which elements decays radioactively is directly proportional to the number of atoms present in it. This is a simple first-order kinetics.
The half-life of a radioactive element is the time taken for half of the radioactive nuclei to disintegrates.
The shorter the half life, the larger the decay constant and the faster the decay process. If a radioactive decay is fast, the mass of the reactants will decrease significantly with time thereby producing more of the daughter isotopes.
The reactant in a radioactive decay are the parent isotopes. The products are the daughter isotopes.
