Answer:

reaction goes backward

as pressure decreases reaction shifts to more no of moles side that is 4 moles on left side

Lemur [1.5K]

Explanation:

Common ion effect is defined as the effect which occurs on equilibrium when a common ion (an ion which is already present in the solution) is added to a solution. This effect generally decreases the solubility of a solute.

Equilibrium reaction of strontium sulfate and sodium sulfate follows the equation:

$RbClO(s)\rightarrow Rb^{+}(aq.)+ClO^{-}(aq.)$

$HClO(aq)+H_2O\rightleftharpoons H_3O^+(aq.)+ClO^{-}(aq.)$

According to Le-Chateliers principle: If there is any change in the variables of the reaction, the equilibrium will shift in the direction in order to minimize the effect.

In the equilibrium reactions, hypochlorite ion is getting increased on the product side, so the equilibrium will shift in the direction to minimize this effect, which is in the direction of hydrogen hypochlorite.

Thus, the addition hypochlorite ions will shift the equilibrium in the left direction.

The dissociation of hydrogen hypochlorite is suppressed due to the common ion effect.

Answer:

The answer is " $42537.93 \ C$ ".

Explanation:

Molar mass : $Z_n = 65.38 \ \frac{g}{mol}\\\\$

$\to Zn^{2+} + 2e^{-} = Zn\\\\$

$\therefore\\\\ \to 65.38 \ g \ of\ Z_n \ require: \\\\ \to 2 \times 96500\ C\\\\\to 14.41 \ g\ require,\\\\ \to \frac{(14.41 \times 2 \times 96500)}{65.38} \ \frac{g}{mol} = 42537.93 \ C$

What is the symbol of an ion with 16 protons, 18 neutrons, and 18 electrons? what is the symbol for an ion that has 16 pro-tons,

Goshia [24]

When we go to periodic table, Sulfur is an element that has 16 protons and 16 electrons.

when there is 18 electrons, with number of two electrons more than protons. This makes it an ion and the ion has a -2 charge.

So when there is16 protons, 18 neutrons, and 18 electrons the symbol is S⁻².

The neutrons have no charge but they add only mass to the elements. So when there is 16 neutrons, it doesn't change the symbol of ion.

A 34.0 gram sample of an un-known hydrocarbon is burned in excess oxygen to form 93.5 grams of carbon dioxide and 76.5 grams of

natka813 [3]

Answer:

The answer to your question is CH₄

Explanation:

Process

1.- Write the possible chemical reaction

CxHy + O₂ ⇒ CO₂ + H₂O

2.- Calculate the amount of carbon in the reaction

Molecular mass of CO₂ = 12 + 32 = 44 g

44 g of CO₂ ------------------- 12 g of carbon

93.5 g of CO₂ ---------------- x

x = (93.5 x 12) / 44

x = 25.5 g of carbon

3.- Calculate the mass of hydrogen in the sample

Molecular mass of water = 2 + 16 = 18 g

18 g of water ------------- 2 g of hydrogen

76.5 g of water -------- x g of hydrogen

x = (76.5 x 2) / 18

x = 8.5 g of hydrogen

4.- Calculate the moles of carbon and hydrogen in the sample

12g of carbon ------------- 1 mol

25.5g of carbon ---------- x

x = (25.5 x 1) / 12

x = 2.12 moles of carbon

1 g of hydrogen ----------- 1 mol

8.5 g of hydrogen -------- x

x = (8.5 x 1) / 1

x = 8.5 moles of hydrogen

5.- Divide both number of moles by the lowest number

carbon = 2.12 / 2.12 = 1

hydrogen = 2.12 = 8,5 / 2.12 = 4

6.- Write the molecular formula

CH₄
