write a balanced chemical equation showing how an aqueous suspension of this compound reacts to the addition of a strong acid. use h to represent the strong acid.

Answers

Answer 1

The balanced chemical equation showing how an aqueous suspension of chromium(III) hydroxide (Cr(OH)3) reacts to the addition of a strong acid (H+) is: Cr(OH)3 + 3H+ → Cr3+ + 3H2O

What is chemical equation?

A chemical equation uses chemical formulas and symbols to clearly depict a chemical reaction. It displays the reactants on the left and the products on the right, with an arrow separating them. The equation lists the names and amounts of the constituent parts of the reaction. For instance:

2H2 + O2 → 2H2O

This equation illustrates how oxygen gas (O2) and hydrogen gas (H2) react to form water (H2O). The stoichiometric ratios, denoted by the coefficients in front of the formulas, show the relative amounts of each substance involved in the reaction.

When a strong acid, represented by H+, is added to an aqueous suspension of chromium(III) hydroxide, the chromium(III) hydroxide acts as a base and accepts the proton (H+). In the balanced equation, three H+ ions react with one molecule of chromium(III) hydroxide, resulting in the formation of chromium(III) ion (Cr3+) and three water molecules (H2O).

Chromium(III) hydroxide has the ability to react with the strong acid due to the presence of hydroxide ions (OH-) in its structure. The hydroxide ions can accept protons from the strong acid, causing the formation of water. This reaction demonstrates the amphiprotic nature of chromium(III) hydroxide, as it can act as a base and accept protons when reacting with a strong acid.

how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by about 200N demonstrate newtons 2nd law

Answers

Answer:

The answer is below

Explanation:

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.

Let F = force, m = mass of object, v = velocity of object, mv = momentum.

F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.

Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:

F = m(dv / dt)

200 N = m[(5 m/s - 0 m/s) / (1 s)]

200 = 5m

m = 40 kg

A sample of an oxide of nitrogen is found to contain 30.4% nitrogen. What is its empirical formula?

Answers

Answer:

If nitrogen = 30.4% then oxygen = 100-30.4 = 69.6%

divide each % value by atomic mass

N = 30.4/14 = 2.17

O = 69.6/16 = 4.35

Divide each y smaller:

N = 2.17/2.17 = 1

O = 4.35/2.17 = 2

Explanation:

"The empirical Formula will be [tex]NO_{2}[/tex]."

What is empirical formula?

In chemistry, an empirical formula is the simplest thought of the entire number quantity of atoms in a molecule.

It is given that N = 30.4%.

The % of O can be determined as: 100-30.4%= 69.65.

Now, after dividing % value with atomic mass, we get.

Mass of  N= 14 and Mass of O = 16.

N= 30.4/14= 2.17

O = 69.6/ 16= 4.35

It can be seen that N has less number as compared to O . So, divide each with 2.17.

N= 2.17/2.17 = 1

O = 4.35/2.17=2

So the empirical formula will be [tex]NO_{2}[/tex].

What mass of MnCl2 is produced when 0.091 g of Cl2 is generated?

Looking at the equation, we need a 4:1 ratio of HCl to MnO2 to make the reaction work, let's see if we have four times as much of the HCl.

As we can see, we have less than the amount of HCl we need for all of the MnO2 to react, therefore the HCl is the limiting reactant.
For the theoretical yield of Cl2, we need to determine how many mols will be produced. As we can see by the equation, four mols of HCl make one mol of Cl2.
Molar Mass of Cl2:

To calculate the actual yield, we multiply the theoretical yield by the final percentage:

Therefore, the actual yield of chlorine is 18.11

The mass of MnCl2 that is produced when 0.091 g of Cl2 is generated is 0.16 g.

Molar mass of MnCl₂ = 55 + 35.5(2) = 126 g/mol

Molar mass of Cl₂ = 35.5(2) = 71 g/mol

If 71 g of Cl₂ gives 126 g of MnCl₂

0.091 g of Cl₂ will give ? of MnCl₂

cross multiply

mass of MnCl₂  produced  = 0.091 × 126 / 71

mass of MnCl₂  produced  = 11.466 / 71

Answer: The ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20 is [tex]1s^22s^22p^63s^23p^5[/tex]

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neutrons and number of protons.

Mass number =  number of neutrons + number of protons

37 = 20 + number of protons

number of protons = 17

The atomic number is specific to an element, and the element with atomic number 17 is chlorine.

Electronic configuration represents the total number of electrons that a neutral element contains.

How many pounds of ice are required to absorb 4900 kJ of heat as the ice melts? The heat of fusion of water is 0.334 kJ/g.

Answers

Answer:

m = 32.34 pounds of ice.

Explanation:

In this case we need to use the following expression of heat:

q = m * ΔHf   (1)

Where:

q: heat absorbed in J or kJ

m: mass of the compound in g

ΔHf: heat of fusion of the water in kJ/g

We are asked to look for the mass of ice in pounds, so after we get the grams, we need to convert the grams to pounds, using the following conversion:

1 pound --------> 453.59 g   (2)

So, we have the heat and heat of fusion, from (1) let's solve for the mass, and then, using (2) the conversion to pounds:

q = m * ΔHf  

m =  q / ΔHf

m = 4900 / 0.334 = 14,670.66 g of ice

Now, the conversion to pounds:

m = 14,670.66 g * 1 pound/453.59 g

m = 32.34 pounds of ice.

What would the [OH-] of a solution that has a pOH of 2.7 be?

Answers

Answer:

The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³

Explanation:

The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution.

pOH indicates the concentration of hydroxyl ions [OH-] present in a solution. In this way, pOH is defined as the negative logarithm of the activity of hydroxide ions, that is, the concentration of OH- ions:

pOH= -log [OH⁻]

In this case, pOH has a value of 2.7. Replacing:

2.7= -log [OH⁻]

and solving:

[OH⁻]=10⁻² ⁷

you get:

[OH⁻]≅ 2*10⁻³

The [OH⁻] of a solution that has a pOH of 2.7 will be 2*10⁻³
