Answer:

1.03 quarts

Explanation:

Both unities are from the volume, the milliliters (mL) is more usual worldwide than the American quart or just quart.

One quart is equivalent to 946.35 mL, so to transform mL in quarts, we should use the relation

1 quart ----------- 946.35 mL

x ----------- 975 mL

By a simple direct three rule:

946.35x = 975

x = 975/946.35

x = 1.03 quarts

Hess’s law

Delvig [45]

From the statement of Hess' law, the enthalpy of the reaction A---> C is +90 kJ

Hess' law of constant heat summation states that for a multistep reaction, the standard enthalpy of reaction is always constant and is independent of the pathway or intermediate routes taken.

From Hess' law, the enthalpy change for the reaction A ----> C is calculated as follows:

A---> C = A ---> B + B ---> C

ΔH of A---> C = 30 kJ + 60 kJ

ΔH = 90 kJ

Therefore, the enthalpy of the reaction A---> C is +90 kJ

The above reaction A---> C can be shown in the enthalpy diagram below:

A -------------------> C (ΔH = +90 kJ)

\ / (ΔH = +60 kJ)

(ΔH = +30 J) \ /

What is Ka for HCN(aq) H+(aq)+CN-(aq)?

snow_lady [41]

<h3> $\tt C.~Ka=\dfrac{[H^+][CN^-]}{[HCN]}$ </h3><h3>Further explanation </h3>

According to Arrhenius, acids are substances which, when dissolved in water, release Hions.

An HₓY acid in water will ionize:

HₓY (aq) ⇒ xH⁺ (aq) + Yˣ- (aq)

In general, the weak acid ionization reaction

HA (aq) ⇒ H⁺ (aq) + A⁻ (aq)

Ka's value

$\large {\boxed {\bold {Ka \: = \: \frac {[H ^ +] [A ^ -]} {[HA]}}}}$

So for HCN

HCN(aq)⇒H⁺(aq)+CN⁻(aq)

$\tt Ka=\dfrac{[H^+][CN^-]}{[HCN]}$

For water at 30C and 1 atm: a= 3.04x10^-4 k^-1 , k =4.52x10^-5 atm ^-1 = 4.46 x10^-10 m^2/N, cpm= 75.3j/9molk), Vm =18.1cm^3/mol

Lapatulllka [165]

Answer:

$C_{vm}$ of water at 30C and 1 atm is 256.834 J/mol·K.

Explanation:

To solve the question, we note the Maxwell relation such as

$C_{pm}-C_{vm}=\frac{9T\alpha ^2 V }{K}$

Where:

$C_{pm}$ = Specific heat of gas at constant pressure = 75.3 J/mol·K

$C_{vm}$ = Specific heat of gas at constant volume = Required

T = Temperature = 30 °C = 303.15 K

α = Linear expansion coefficient = 3.04 × 10⁻⁴ K⁻¹

K = Volume comprehensibility = 4.52 × 10⁻⁵ atm⁻¹

Therefore,

75.3 - $C_v$ = $\frac{9\times 303.15 \times (3.04 \times 10^{-1} 1.81 \times 10^{-5} }{4.52 \times 10^{-5} }$

$C_{vm}$ = $\frac{9\times 303.15 \times (3.04 \times 10^{-1} 1.81 \times 10^{-5} }{4.52 \times 10^{-5} }$ - 75.3 = 256.834 J/mol·K.
