Which non metal is highly reactive

Which Non Metal Is Highly Reactive

Answers

Answer 1

Answer:

element fluorineThe most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal.

It will be less because pressure is directly proportional to temperature

You are studying the boiling points of liquids with some fellow students. You have two liquids of different molecular weights, and you test each of them twice. You find that the one with a lower molecular weight also has a lower boiling point. You would like to be more confident with the pattern you are noticing. What are two possible next steps? In one to two sentences, give specific, different examples of how the experiment could be extended, assessed, or improved.

Answers

The boiling points of two or three other pairs of liquids in which one liquid has a lower molecular mass than the other can be studied in order to see if the pattern is consistent.

The boiling point of a substance refers to the temperature at which its vapor pressure is equal to the atmospheric pressure. The boiling point of a substance has a lot to do with its molecular mass.

Generally, substances that has a higher molecular mass has a higher boiling point except other factors at at work. In order to confirm whether the pattern that you are noticing about molecular weights and boiling point is consistent, three other liquids with different molecular masses, one being higher than the other can be studied and their boiling points compared.

Tom pushes on a 50-kilogram box with a force of 25 newtons. Assuming the surface on which the box moves is frictionless, at what rate does the box accelerate?

Answers

Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 [tex]m/s^2[/tex].

Given the following data:

Mass of box = 50 kilogramForce = 25 newtons.

To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:

Mathematically, Newton's Second Law of Motion is given by the formula;

[tex]Force = mass \times acceleration[/tex]

Making acceleration the subject of formula, we have:

[tex]Acceleration =\frac{Force}{mass}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Acceleration = \frac{25}{50}[/tex]

Acceleration = 0.5 [tex]m/s^2[/tex]

Oxygen is produced by the reaction of sodium peroxide, Na2O2 , and water.
2 Na2O2 (s) + 2 H2O(l) ---> O2(g) + 4 NaOH(aq)
Calculate the mass of Na2O2 in grams needed to form 5.20 g of oxygen.

Answers

Answer: 23.53g

Explanation:

5.2/(2x16) = 0.1625 mol

0.1625 x 2 = 0.325 mol

0.325 x (23 x 2 + 16 x 2) = 78 x 0.325 = 23.53g

Determine the mass of O(2-) ions in 3 mol of alumina (Al2O3). Molar mass of O = 16)

Answers

Considering the rule of three and molar mass of O, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.

By multiplying the number of moles by the subscripts next to each atom, you get the amount of each element present in the compound. IIf the same atom appears more than once in the compound, you must add its amounts.

So, in 1 mole of Al₂O₃, you have 2 ions of O²⁻.

Then you can apply the following rule of three: if 1 mole of the compound contains 2 ions of O²⁻, 3 moles of the compound contains how many ions of O²⁻?

[tex]amount of ions of O^{2-} =\frac{3 moles of Al_{2} O_{3} x2 ions of O^{2-}}{1mole of Al_{2} O_{3} }[/tex]

amount of ions of O²⁻= 6 ions

Being the molar mass of O 16 g/mole, this is the amount of mass that a substance contains in one mole, then the mass of O²⁻ can be calculated as:

6 x 16 g/mole= 96 grams

Finally, the mass of O²⁻ ions in 3 mol of alumina Al₂O₃ is 96 grams.

How many grams of CO2 are produced using 0.29 moles of O2?

Answers

The mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The reaction between carbon and pxygen atom is exprssed as:

C + O2 -> CO2

From he balanced equation, we can see that 1 mole O2 reacted to produce 1 mole of CO2.

Hence if 0.29 moles of CO2 was used in the reaction, the number of moles of CO2 produced will be 0.29 moles as well.

Mass of CO2 = number of moles * molar mass

Mass of CO2 = 0.29 * (12 + 32)

Mass of CO2 = 0.29 * 44

Mass of CO2 = 12.76grams

Hence the mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

Read the following chemical equations.

Reaction 1: 2KI + H2O2 2KOH + 12
Reaction 2: Cl2 + H2 → 2HCI

Which of the following statements is true for both the chemical equations?

A. I is oxidized in reaction 1 and Cl2 is oxidized in reaction 2.

B. I is reduced in reaction 1 and Cl2 is reduced in reaction 2.

C. I is oxidized in reaction 1 and Cl2 is reduced in reaction 2.

D. I is reduced in reaction 1 and Cl2 is oxidized in reaction 2.​

Answers

This problem is providing two reduction-oxidation (redox) reactions in which the oxidized and reduced species can be identified by firstly setting the oxidation number of each element:

Reaction 1: 2K⁺I⁻ + H₂⁺O₂⁻  ⇒2K⁺O⁻²H⁺ + I₂⁰

Reaction 2: Cl₂⁰ + H₂⁰ ⇒ 2H⁺CI⁻

Next, we can see that iodine is being oxidized and oxygen reduced in reaction #1 and chlorine is being reduced and hydrogen oxidized in reaction #2 because the oxidized species increase the oxidation number whereas the reduced ones decrease it.

In such a way, the correct choice is C.

6.5 moles of AgCl can be formed from 6.5 moles of Ag.

STOICHIOMETRY:

According to this question, silver reacts with hydrochloric acid to form silver chloride and hydrogen gas as follows:

2Ag + 2HCl → 2AgCl + H2

Based on this balanced equation, 2 moles of silver (Ag) produces 2 moles of silver chloride (AgCl).

This means that 6.5 moles of Ag will produce (6.5 × 2)/2 = 6.5 moles of AgCl.
