4.8 moles of Kl are dissolved in 850 mL of water. What is the molarity of the solutions?

Answers

Answer 1
Hey there!

Molarity = 4.8/850 x 1000 =5.647mol/lit or 5.65M

Hope this helps you dear :)
Have a good day :)

In a covalent bond between Cl and H, ( ) tends to attract electron density from the other element in the bond.

Answers

Answer:

Cl

Explanation:

In a covalent bond between Cl and H, (Cl) tends to attract electron density from the other element in the bond.

Chlorine is more electronegative than hydrogen. In general, elements towards the top-right of the periodic table are more electronegative. This is because these elements are desperate for a few more electrons to fill their outermost shell (and have a full octet). The more electronegative an element is, the more it wants electrons. As a result, highly electronegative atoms have a greater pull on the electrons in a covalent bond.

The Keq for the decomposition of hydrogen iodide to form hydrogen and iodine as follows

2HI(g)

H2(g) + I2(g)

is 1.6 x 10–4. If the concentration at equilibrium of H2 and I2 are each 2 x 10–3 M, what is [HI]?

Answers

The equilibrium constant (Keq) is given for the reversible reactions. The concentration of hydrogen iodide will be 1.58 M.

What is Keq?

The equilibrium constant (Keq) is the proportion of the ratios of the concentration of the products to the reactants.

The balanced chemical reaction is shown as:

2HI  ⇔ H₂ + I₂

The equilibrium expression for the reaction can be given as:

Keq = [H₂] [I₂] / [HI]²

Given,

Equilibrium constant = 1.6 × 10⁻⁴

Concentration of dihydrogen = 2  × 10⁻³ M

Concentration of iodine = 2 × 10⁻³ M

The concentration of hydrogen iodide is calculated as:

1.6 × 10⁻⁴ = [ 2  × 10⁻³ M][2  × 10⁻³ M] ÷ [HI]²

[HI]² = 4  × 10⁻⁶ ÷ 1.6 × 10⁻⁴

= 2.5 M

[HI] = 1.58 M

Therefore, 1.58 M is the concentration of hydrogen iodide.

A gas has a pressure of 853.0 millibars at a temperature of 29.0 °C. If the volume is unchanged but the temperature is increased to 85.0 °C,
what is the new pressure of the gas?
=

Answers

The new pressure of the gas that initially have a pressure of 853.0 millibars at a temperature of 29.0 °C is 1011.17 millibars. Details about pressure can be found below.

How to calculate pressure?

The pressure of a given gas can be calculated using the following formula:

P1/T1 = P2/T2

Where;

P1 = initial pressure = 853.0 millibarsP2 = final pressure = ?T1 = initial temperature = 29°C + 273 = 302KT2 = final temperature = 85°C + 273 = 358K

853/302 = P2/358

358 × 853 = 302P2

305374 = 302P2

P2 = 305374 ÷ 302

P2 = 1011.17 millibars

Therefore, the new pressure of the gas that initially have a pressure of 853.0 millibars at a temperature of 29.0 °C is 1011.17 millibars.

The rule of three or is a way of solving problems of proportionality between three known

values and an unknown value, establishing a relationship of proportionality between all of

them. That is, what is intended with it is to find the fourth term of a proportion knowing the

other three. Remember that proportionality is a constant relationship or ratio between different

magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so

does the other (or when one magnitude decreases, so does the other), the direct rule of three

must be applied. To solve a direct rule of three, the following formula must be followed:

ab

cx

So

C*b

T =

In this case, it is possible to use the reaction stoichiometry of the reaction (that is, the

relationship between the amount of reagents and products in a chemical reaction) and the rule

of three to calculate the quantities of moles requested:
