Answer:

Chemical Properties of Nonmetals :

Nonmetals are poor conductors of heat and electricity. ...

Unlike metals, nonmetals aren't malleable and ductile.

Nonmetals react more with metals than with nonmetals.

Usually, nonmetals react with other nonmetals in high temperature.

Most nonmetals do not react with air in room temperature.

What is the mole ratio of H2O to C8H8?

zepelin [54]

Answer:

Mole ratio for a compound

The chemical formula tells us the mole ratio.

CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms.

Mole ratio for a reaction

The balanced chemical reactions tells us.

C12H22O11 + 12 O2  12 CO2 + 11 H2O

1 C12H22O11 molecule: 12 O2 molecules : 12 CO2

molecules : 11 H2O molecules.

Determine the molar solubility of AgBr in a solution containing 0.150 M NaBr. Ksp (AgBr) = 7.7 × 10-13.

lesya692 [45]

Answer:

Molar solubility of AgBr = 51.33 × 10⁻¹³

Explanation:

Given:

Amount of NaBr = 0.150 M

Ksp (AgBr) = 7.7 × 10⁻¹³

Find:

Molar solubility of AgBr

Computation:

Molar solubility of AgBr = Ksp (AgBr) / Amount of NaBr

Molar solubility of AgBr = 7.7 × 10⁻¹³ / 0.150

Molar solubility of AgBr = 51.33 × 10⁻¹³

<u>Answer:</u> The mass of morphine is 0.059 grams

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of sulfuric acid solution = 0.0116 M

Volume of solution = 8.92 mL

Putting values in above equation, we get:

$0.0166M=\frac{\text{Moles of sulfuric acid}\times 1000}{8.92}\\\\\text{Moles of sulfuric acid}=\frac{0.0116\times 8.92}{1000}=1.035\times 10^{-4}mol$

The given chemical equation follows:

$2C_{17}H_{19}NO_3+H_2SO_4\rightarrow \text{Product}$

By Stoichiometry of the reaction:

1 moles of sulfuric acid reacts with 2 moles of morphine

So, $1.035\times 10^{-4}mol$ of sulfuric acid will react with = $\frac{2}{1}\times 1.035\times 10^{-4}=2.07\times 10^{-4}mol$

To calculate the mass of morphine for given number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Molar mass of morphine = 285.34 g/mol

Moles of morphine = $2.07\times 10^{-4}mol$

Putting values in above equation, we get:

$2.07\times 10^{-4}mol=\frac{\text{Mass of morphine}}{285.34}\\\\\text{Mass of morphine}=(2.07\times 10^{-4}mol\times 285.34g/mol)=0.059g$

Hence, the mass of morphine is 0.059 grams

Choose the statement below that is TRUE.

Leni [432]

Answer: Option (a) is the correct answer.

Explanation:

A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.

For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

$CH_{3}COOH(aq) \rightleftharpoons CH_{3}COO^{-}(aq) + H^{+}(aq)$

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.

For example, HCl is a strong acid and when dissolved in water it dissociates completely.

$HCl \rightarrow H^{+} + Cl^{-}$

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.
