5 carbons are in the molecule. Isotopes are atoms with a constant number of protons but a variable number of neutrons.

<h3>What factors affect an isotope's relative abundance?</h3>

Isotopes are atoms with a constant number of protons but a variable number of neutrons. Atomic masses vary among isotopes.

The proportion of atoms with a particular atomic mass that can be found in a sample of an element that is found naturally is known as the relative abundance of an isotope.

Relative abundance chemistry issues should be solved using the formula below:

(M1)(x) + (M2)(1-x) = M (E)

Issue illustration Determine the relative abundance of the isotopes if the masses of two different nitrogen isotopes are 0.42 amu for carbon-0.42 and 0.065 amu forcarbon-0.065.

Equation x = 0.996 can be found using algebra.

0.42 * 0.996 + 0.065 *0.996 = 0.424794.

5 carbons are in the molecule.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚C inside a freezer for a night. When he took it out, its new volu
ad-work [718]

Initial volume of the balloon = V_{1}= 348 mL

Initial temperature of the balloon T_{1} = 25.0^{0}C + 273 = 298 K

Final volume of the balloon V_{2} = 322 mL

Final temperature of the balloon = T_{2} = ?

According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.

\frac{V_{1} }{T_{1} } =\frac{V_{2} }{T_{2} }

On plugging in the values,

\frac{348mL}{298 K} =\frac{322 mL}{T_{2} }

T_{2} =276 K

Therefore, the temperature of the freezer is 276 K

How many grams of mercury can be produced if 18.0 g of mercury (11) oxide decomposes?
NARA [144]

Answer:

18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury

Explanation:

Mercury oxide has molar mass of 216.6 g/ mol. It gas a molecular formula of HgO.

The decomposition of mercury oxide is given by the chemical equation below:

2HgO ----> 2Hg + O₂

2 moles of HgO decomposes to produce 1 mole of Hg

2 moles of HgO has a mass of 433.2 g

433.2 g of HgO produces 216.6 g of Hg

18.0 of HgO will produce 18 × 216.6/433.2 g of Hg = 9.0 g of Hg

Therefore, 18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury
