Answer:

Covalent bond is a bond that shared electrons between two neutral atoms.

Explanation:

The chemical link between any two ion or atom that is formed by sharing electron pairs is called as covalent bond. It is also known as molecular bond. Nonmetal atoms with relatively close or similar electronegativity values form a covalent bond. The major types of covalent bonds are polar and non-polar. When atoms share an equal number of electron pair, non-polar covalent bond is formed. In polar covalent bonds, the atoms share inequal pair of electrons. The compounds that are formed through covalent bonds have low boiling points and melting points. They have low enthalpies of vapourisation and fusion and are also highly flammable.

inn [45]

Answer : The molarity of solution is, 1.73 mole/L

Explanation :

The relation between the molarity, molality and the density of the solution is,

where,

$d=M[\frac{1}{m}+\frac{M_b}{1000}]$

d = density of solution = $0.876g/cm^3=0.876g/mL$

m = molality of solution = 2.41 mol/kg

M = molarity of solution = ?

$M_b$ = molar mass of solute (toluene) = 92 g/mole

Now put all the given values in the above formula, we get the molality of the solution.

$0.876g/ml=M\times [\frac{1}{2.41mol/kg}+\frac{92g/mole}{1000}]$

$M=1.73mol/L$

Therefore, the molarity of solution is, 1.73 mole/L

What is the concentration of hydrogen ions in a solution with a pH of 2.36?

Viefleur [7K]

Answer:

Explanation:

$pH = - log[H {}^{ + } ] \\ 2.36 = - log[H {}^{ + } ] \\ [H {}^{ + } ] = {10}^{ - 2.36} \\ [H {}^{ + } ] = 4.37 \times {10}^{ - 3} \: M$

A student determines the aluminum content of a solution by first precipitating it as aluminum hydroxide, and then decomposing th

Vladimir [108]

Answer: The student should obtain 1.103 g of aluminum oxide 

Explanation:

First we write down the equations that represent the aluminum hydroxide precipitation from the reaction between the aluminum nitrate and the sodium hydroxide:

Al(NO3)3 + 3NaOH → 3NaNO3 + Al(OH)3

Now, the equation that represents the decomposition of the hydroxide to aluminum oxide by heating it.

2Al(OH)3 → Al2O3 + 3H2O

Second, we gather the information what we are going to use in our calculations.

Volumen of Al(NO3)3 = 40mL

Molar concentration of Al(NO3)3 = 0.541M

Molecular Weight Al2O3 = 101.96 g/mol

Third, we start using the molar concentration of the aluminum nitrate and volume used to find out the total amount of moles that are reacting

$\frac{0.541moles Al(NO3)3}{1L} x\frac{1L}{1000mL} x 40mL Al(NO3)3 = 0.022moles Al(NO3)3$

then we use the molar coefficients from the equations to discover the amount of Al2O3 moles produced

$0.022moles Al(NO3)3 x \frac{1mol Al(OH)3}{1mol Al(NO3)3} X\frac{1mol Al2O3}{2molAl(OH)3} = 0.011 moles Al2O3$

finally, we use the molecular weight of the Al2O3 to calculate the final mass produced.

$0.011moles Al2O3 x \frac{101.96g Al2O3}{1mol Al2O3} = 1.103g Al2O3$
