Name the compound Cd(MnO4).

Starting with a vessel of temperature 50.1°C, a pressure of 6263.MmHg and volume 461.1mL, what is its final volume, in liters, i

il63 [147K]

Answer:

The value of final volume inside the vessel $V_{2}$ = 5.17 ml

Explanation:

Initial pressure $P_{1}$ = 6263 mm Hg = 8.24 atm = 835 K pa

Initial temperature $T_{1}$ = 50.1 ° c = 323.1 K

Initial volume $V_{1}$ = 461.1 ml = 0.0004611 $m^{3}$

Final temperature $T_{2}$ = - 95.8 ° c = 177.2 K

Finial pressure $P_{2}$ = 411 atm = 41644.6 K PA

We know that

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

Put all the values in the above equation

⇒ 835 × $\frac{0.0004611}{323.1}$ = 41644.6 × $\frac{V_{2} }{177.2}$

⇒ $V_{2}$ = 5.07 × $10^{-6}$ $m^{3}$

⇒ $V_{2}$ = 5.17 ml

This is the value of final volume inside the vessel.

HClO4+P4O10=H3PO4+Cl2O7 how do you balance this?

Tom [10]

12 HClO₄ + 1 P₄O₁₀ → 4 H₃PO₄ + 6 Cl₂O₇

<h3>Explanation</h3>

Balance by the conservation of atoms.

Assign coefficient 1 to the species with the largest number of elements and atoms. H₃PO₄ contains three elements. Each of its molecule contains eight atoms, that's two more than the six atoms in a HClO₄ molecule. Start by assigning H₃PO₄ a coefficient of 1.

? HClO₄ + ? P₄O₁₀ → 1 H₃PO₄ + ? Cl₂O₇

There are now three H atoms, one P atom on the product side. H₃PO₄ is the only product that contains H and P atoms. As a result, there should be the same number of H and P atoms on the reactant side.

Among all reactants, only HClO₄ contains H atoms. Each HClO₄ molecule contains one H atom. Three H atoms correspond to three HClO₄ molecule.
Among all reactants, only P₄O₁₀ contains P atoms. Each P₄O₁₀ molecule contains four P atoms. One P atom corresponds to 1/4 of a P₄O₁₀ molecule.

Thus

3 HClO₄ + 1/4 P₄O₁₀ → 1 H₃PO₄ + ? Cl₂O₇

There are three Cl atoms in three HClO₄ molecules. HClO₄ is the only species that contains Cl among all reactants. There are three Cl atoms on the reactant side and shall be the same number of Cl atoms on the product side.

Cl₂O₇ is the only molecule that contains Cl among the products. Each Cl₂O₇ molecule contains two Cl atoms. Three Cl atoms will correspond to 3/2 Cl₂O₇ molecules.

3 HClO₄ + 1/4 P₄O₁₀ → 1 H₃PO₄ + 3/2 Cl₂O₇

Multiply both sides by the least common multiple of the denominators to eliminate the fraction. The least common multiple in this case is four.

12 HClO₄ + 1 P₄O₁₀ → 4 H₃PO₄ + 6 Cl₂O₇

From E=mc²=hv show that wavelength=h/mv

barxatty [35]

Explanation:

To show - from E=mc²=hv show that wavelength=h/mv

Proof -

Given that,

E = mc²

E = hν

By equating both the equations, we get

mc² = hν

Because real particles do not travel at the speed of light, De Broglie submitted velocity ( v ) for the speed of light ( c ).

mv² = hν

Through the equation λ , de Broglie substituted v/λ for ν and arrived at the final expression that relates wavelength and particle with speed.

mv² = hv/λ

⇒λ = hv/mv²

⇒λ = h/mv

Hence showed.

Which of these substances, when dissolved in water, is a strong electrolyte? which of these substances, when dissolved in water,

Norma-Jean [14]

Option C. It is sodium nitrate because it is a strong electrolyte that comes from a strong acid (HNO3) and a strong base (KOH). It becomes a strong electrolyte when it dissolves in water, its formula is NaNO3, which is a compound that forms nitrate together with potassium nitrate and is obtained by chemical synthesis.
