11.Calculate the molar mass of Fe2(SO3)3

Answers

The molar mass of Fe2(SO3)3 is 351.8796 moles.

What is molar mass?

Molar mass is defined as the mass equivalent of an element's or a chemical compound's Avogadro number of atoms or molecules, respectively. A mole is defined as the quantity of atoms, molecules, or ions that are present in a substance. It is additionally referred to as the volume of material that contains the same number of discrete units.

Molar mass of Fe2(SO3)3

= 2 × 55.845 + 3 × 32.065 + 9 × 15.9994

= 111.69 + 96.195 + 143.9946

= 351.8796 moles.

The substance iron(III) sulfite, sometimes known as ferrous sulfite, has the chemical formula Fe2(SO3)3. The family of inorganic compounds known as iron(III) Sulphate, sometimes known as ferric Sulphate, has the formula Fe2(SO4)3(H2O)n.

Thus, the molar mass of Fe2(SO3)3 is 351.8796 moles.

Topic 1 Homework Homework – Due in 13 hours T2HW Question 16 - Challenge Homework – Unanswered The distance from San Francisco to Los Angeles is approximately 385 miles. You and your friends decide to cycle from San Francisco to Los Angeles. If the distance between the cities is about 385 miles and your doctor tells you that you need to drink 1 L of water for every 1 km that you cycle, how many Lof water will each cyclist need to drink on the journey? Enter your answer as a number using 3 significant figures without units. Do not enter the word "liters" as part of your answer. 1609 m = 1.0 mi Numeric Answer Unanswered

Answers

Answer:

Each cyclist will need to drink 619 l

Explanation:

Hi there!!

First, let´s convert the miles to kilometers:

If 1.0 mi = 1609 m, then 385 mi will be:

385 mi · (1609 m/ 1.0 mi) · (1 km/ 1000 m) = 619 km

Now, if each cyclist need to drink one liter water per kilometer ( I think that´s a lot of water!), for the entire journey each cyclist will need to drink:

619 km · 1 l/km = 619 l

Then, each cyclist will need to drink 619 l.

1. When an object wants to stay at rest or wants to stay in motion unlessan outside force comes and disturbs it.*

Answers

Newton's first law of motion describes inertia. According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.

Write the expression for the equilibrium constant Kp for the following reaction. Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH3 )2 as (P NH3)2. If either the numerator or denominator is 1, please enter 1 2 MoO3(s) ↔ 2 MoO2(s) + O2(g)

Answers

The expression for the equilibrium constant Kp for the following reaction is $K_p = (po_2)$

Equilibrium constant:

It refers to the ratio of the concentration of products to the concentration of reactants where each raised to the power of their stoichiometric ratios. It is expressed as K.

Since the given expression is

MoO3(s) ↔ 2 MoO2(s) + O2(g)

So, the above expression should be considered for constant kp

Answer: $K_p={(p_(O_2))}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K$

$K_p$ is the constant of a certain reaction at equilibrium for gaseous reactants and products.

For the given chemical reaction:

$MoO_3(s)\rightleftharpoons 2MoO_2(s)+O_2(g)$

The expression of for above equation follows:

$K_p={(p_(O_2))}$

As solids do not exert pressure, $MoO_3$ and $MoO_2$ are not involved.
