How many grams of
diphosphorus trioxide, P2O3, are
required to produce 10.2 moles of
phosphorous acid, H3PO3?

P2O3 + 3H₂O → 2H3PO3

[?] g P₂O3

Answers

From the equation, we know that for every 2 moles of phosphorous acid produced, 1 mole of diphosphorus trioxide is consumed.

This means that we need to find the mass of 10.2/2 = 5.1 moles of diphosphorus trioxide.

The atomic mass of phosphorous is 30.973761998 g/mol.The atomic mass of oxygen is 15.9994 g/mol.

So, the formula mass of diphosphorus trioxide is:

2(30.973761998)+3(15.9994)=109.945723996 g/mol.

Thus, 5.1 moles have a mass of:

5.1(109.945723996), which is about 561 g (to 3 sf)

Answers

.A solution that serves as a pH indicator may be made using red cabbage, which is frequently available in homes. In essence, the color of the cabbage depends on the acidity of the solution and a pigment molecule called flavin or anthocyanin.

To determine whether a material is an acid or a base, red cabbage indicator is a purple-colored solution

Vinegar is an acid and its pH value is less than 7 and hence

Red color is produced

Baking soda is base and its pH value is greater than 7 and between 8-9  

and the color produced is sky blue

Bleach is the green which is also a basic and because the pH value is 10-11

Householder cleaner is having pH 11-13 which is basic and hence the yellow is the color of household cleaner .

A basic solution goes away from being basic and toward the center of the pH scale when an acid is introduced. The base is "neutralized" in this manner.

A 2. 75-l container filled with co2 gas at 25°c and 225 kpa pressure springs a leak. When the container is re-sealed, the pressure is 185 kpa and the temperature is 10°c. How many moles of gas were lost?.

Answers

Answer:

Moles Lost = 0.0335 moles

Explanation:

This type of question requires the Ideal Gas Law equation. The equation looks like this:

PV = nRT

In this formula,

-----> P = pressure (kPa)

-----> V = volume (L)

-----> n = number of moles

-----> R = constant (8.314 L*kPa/mol*K)

-----> T = temperature (K)

(Step 1)

To find how many moles were lost, you first need to find how many moles you had to begin with. This can be done by plugging the starting values into the equation and solving for "n". But first, you need to convert Celsius to Kelvin (by adding 273.15).

P = 225 kPa                  R = 8.314 L*kPa/mol*K

V = 2.75 L                     T = 25°C + 273.15 = 298.15 K

n = ?

PV = nRT

(225 kPa)(2.75 L) = n(8.314 L*kPa/mol*K)(298.15 K)

618.75 = n(2478.8191)

0.250 = n

(Step 2)

Next, you need to find the number of moles in the container after it has been re-sealed. The volume is the same because the container did not change. The process should be the same as above.

P = 185 kPa                   R = 8.314 L*kPa/mol*K

V = 2.75 L                     T = 10°C + 273.15 = 283.15 K

n = ?

PV = nRT

(185 kPa)(2.75 L) = n(8.314 L*kPa/mol*K)(283.15 K)

508.75 = n(2354.1091)

0.216 = n

(Step 3)

Finally, you can find the number of moles lost by subtracting the final amount of moles from the original amount. When doing this calculation, I used the value of the moles saved in my calculator (with more decimal places) to get a more accurate number.

Moles Lost = Initial Moles - Final Moles

Moles Lost = 0.250 moles - 0.216 moles

Moles Lost = 0.0335 moles

Explanation:

Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions

Example: Water decomposes into a mixture of hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances elements.

Each element is represented by a unique symbol. The notation for each element can be found on a periodic table of elements.

The elements can be divided into three categories that have characteristics properties: metals, nonmetals and semimetals. Most elements are metals, which are found on the left and toward the bottom of the periodic table. A handful of nonmetals are clustered in the upper right corner of the periodic table. The semimetals can be found along the dividing line between the metals and the nonmetals.

What would cause a nucleus to be unstable?

B. Too few quarks within the nucleus of the atom

D. An imbalance between the electrostatic and strong nuclear forces
SUBMIT

Answers

D

I don’t know how to explain it, but when there are 8 outermost outer nuclear electrons, it’s the most stable time, lose e- will make it unstable

The instability of the nucleus is due to an imbalance between the electrostatic and strong nuclear forces, which is option D.

A nucleus can become unstable if there is an imbalance between the electrostatic repulsion between protons and the strong nuclear force that holds the nucleus together. The electrostatic repulsion between protons tends to push them apart, while the strong nuclear force acts to hold the protons and neutrons together.

If the number of protons in the nucleus is too large, the electrostatic repulsion becomes stronger, making the nucleus unstable. Similarly, if the number of neutrons is too large or too small compared to the number of protons, it can also lead to an imbalance in the forces and instability of the nucleus.

Therefore, the correct option is option d.

Answers

the fireworks give off heat

The best explanation for why a firework being ignited is an example of an exothermic reaction and not an endothermic reaction is:

The fireworks give off heat.

Heat is emitted into the environment in an exothermic reaction. When a firework is lit, it undergoes a number of chemical processes inside the firework combination, which produces gases and produces a great deal of heat. Fireworks' distinctive visual display and audible effects are produced when heat is released as light and sound.

In contrast, heat is taken from the environment during an endothermic reaction. If a reaction were endothermic, it would need an outside energy source to continue, and because it would be absorbing heat from its environment, it would feel chilly to the touch.

However, because they release heat and energy and brighten the night sky, fireworks are instances of exothermic reactions.
