HELP ASAP 20 PTS!!!Fireworkium (Fw): This element has 15 protons and 15 electrons in its neutral atom.

Toothium (T): This is a nonmetal with an average atomic mass number close to 19.

Floatium (Fl): This is a gas that the aliens often use to fill balloons and blimps. It contains two protons in its nucleus.

Breathium (Bt): This element is a nonmetal and has one less proton than an atom of Toothium and has an atomic mass close to 16 amu.

Lightium (Lg): This is a gas that does not react with other elements. It glows when it is heated in a lamp or vacuum tube. It contains one more proton in its nucleus than Toothium.

Rottoneggium (Re): This is a nonmetal with one less electron than Mustarium. It has a total of 16 electrons in its electron cloud.

I honestly don't understand

Answers

Answer 1

Answer: Basically they are asking you to find the element that is most closely associated with these clues.

1. Fireworkium: 15 protons and 15 electrons? No problem. We can see that the atomic number is 15, in which in real life, the element is Phosphorous. (Phosphorous is a common element in fireworks for an explosive personality and colors)

2. Toothium: A nonmetal with average mass number close to 19? We check the periodic table once more and find that Fluorine is our answer. (Notice that fluorine is in toothpaste, which is why they decided the name Toothier)

3. Breathium: Now honestly, I didn't even have to check the periodic table but just realize that we breath Oxygen. But if you want the straight answer, Oxygen is a nonmetal which has an atomic mass close to 16, and surprise, it has one less proton than Fluorine.

4.Lightium: Immediately we see that since this gas does not react with other elements, it is a noble gas. If it glows in a lamp or vacuum tube, we can also see it is of a light origin. If it has one more proton than Toothium (Fluorine) than we can immediately see that in the periodic table, our answer is Neon.

5. Rottoneggium: We can immediately guess sulfur. The straight way shows that it has 16 electrons, and the non-ion atom should also have 16 protons. Therefore, our answer is Sulfur.

6. I just realized I forgot Floatium: If it has 2 protons, we look in the periodic table and see that our answer is Helium.

If a gas occupies 22.4 L at 0.265 atm, then what will the pressure be in atmospheres if the gas occupies 35.52 L? Assume all othervariables are held constant
A)0.167 atm
B)0.437 atm
C)0.886 atm
D)149 atm

Answers

Answer:

The new pressure is 0.167 atm

The correct answer is option A

Explanation:

Step 1: Data given

Volume of the gas = 22.4 L

Pressure of the gas = 0.265 atm

The volume increases to 35.52 L

Step 2: Calculate the new pressure

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 0.265 atm

⇒with V1 = the initial volume = 22.4 L

⇒with P2 = the new pressure = TO BE DETERMINED

⇒with V2 = the increased volume = 35.52 L

0.265 atm * 22.4 L = P2 * 35.52 L

P2 = (0.265 atm * 22.4 L) / 35.52 L

P2 = 0.167 atm

The new pressure is 0.167 atm

The correct answer is option A

What is the purpose of a catalyst in the production of hydrogen?

Answers

Answer:To speed up the rate of hydrogen production

Explanation:

In the preparation of Hydrogen from the action of dilute acid on zinc metal, few drops of Copper(II)tetraoxosulphate(VI) solution is added to speed up the rate of production.

The hydrogen produced is shown in the equation below

Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)

Thus, Copper(II)tetraoxosulphate(VI) solution, a catalyst is used to speed up hydrogen production.
