Answer:

The specific heat capacity of silver metal is 0.021485 J/g°C.

Explanation:

The specific heat capacity of silver metal can be found out by using the formula,

Q = (mass) (ΔT) (Cp)

Given,

mass = 75 grams

Q = 56.4 j

ΔT = 35°C

Substituting values,

56.4 = (75)(35)(Cp)

Cp = 0.021485 J/g°C.

Silver nitrate can be produced by dissolving metallic silver in concentrated nitric acid, with an addition product being hydroge
geniusboy [140]

Answer:

2Ag(s) + 2HNO₃ (aq)  →  2AgNO₃(aq)  +  H₂(g)

Explanation:

Metallic silver = Ag (s)

Concentrated nitric acid = HNO₃ (aq)

Product being hydrogen gas = H₂(g)

2Ag(s) + 2HNO₃ (aq)  →  2AgNO₃(aq)  +  H₂(g)

Be careful AgNO₃ doesn't precipitate

Calculate the [OH-] and the pH for a solution of 0.24M methylamine, CH3NH2. Kb = 3.7 X 10-4.
Naddika [18.5K]

Answer:

[OH^-]=9.24x10^{-3}M.

pH=11.97.

Explanation:

Hello,

In this case, since the ionization of methylamine is:

CH_3NH_2(aq)+H_2O(l)\rightleftharpoons CH_3NH_3^+(aq)+OH^-(aq)

The equilibrium expression is:

Kb=\frac{[CH_3NH_3^+][OH^-]}{[CH_3NH_2]}

And in terms of the reaction extent x which is equal to the concentration of  OH⁻ as well as that of CH₃NH₃⁺ via ice procedure we can write:

3.7x10^{-4}=\frac{x*x}{024-x}

Whose solution for x via quadratic equation is 9.24x10⁻³ M since the other solution is negative so it is avoided. Therefore, the concentration of OH⁻ is:

[OH^-]=x=9.24x10^{-3}M

With which we can compute the pOH at first:

pOH=-log([OH^-])=-log(9.24x10^{-3})=2.034

Then, since pH and pOH are related via:

pH+pOH=14

The pH turns out:

pH=14-pOH=14-2.034\\\\pH=11.97

Best regards.

Which oxide(s) of manganese have a mass percent of the metal that is greater than 50%?MnO MnO2 Mn2O3All of these210
gtnhenbr [62]

Answer:

All of these oxides of manganese have a mass percent of metal greater than 50%

Explanation:

Step 1: Data given

Molar mass of Mn = 54.94 g/mol

Molar mass of O = 16 g/mol

<em><u>Step 2: Calculate mass % of Mn in MnO</u></em>

Molar mass of MnO = 54.94 + 16 = 70.94 g/mol

% Mn = (54.94/70.94)*100 % = 77.45 %

<u><em>Step 3: Calculate % of Mn in MnO2</em></u>

Molar mass of MnO2 = 54.94 + 2*16 = 86.94 g/mol

% Mn = (54.94/86.94) * 100% = 63.19 %

<u><em>Step 4: Calculate % of Mn in Mn2O3</em></u>

Molar mass of Mn2O3 = 2*54.94 + 3*16 = 157.88 g/mol

% Mn = ((2*54.94)/157.88)*100 % = 69.6 %

All of these oxides of manganese have a mass percent of metal  greater than 50%
