Answer 1
An electron in motion generates an electromagnetic field and is in turn deflected by external electromagnetic fields. When an electron is accelerated, it can absorb or radiate energy in the form of photons. Electrons, together with atomic nuclei made up of protons and neutrons, make up the

The net ionic equation for the acid-base reaction of hydrochloric acid with phosphine is PH3(aq) + H⁺(aq)  → PH⁺₄ (aq)

What is a Chemical reaction?

A chemical reaction shows us how substances interact which brings about  changes in the  composition of the  reactants. Two types of Chemical reactions includes:

the net ionic equation balanced chemical equation.

The net ionic equation of a  chemical equation tells us only elements and ions directly involved in the chemical reaction.

Now for the reaction of hydrochloric acid, HCl with phosphine, PH3,

First write the aqueous substances in their ionic components

PH3(aq) + HCl(aq)→ PH4Cl(aq)

PH3(aq) + H⁺(aq) +Cl⁻(aq) → PH⁺₄ (aq) + Cl⁻(aq)

Then we  remove the ions that do not take part in the reaction,  Cl⁻(aq)

So we are left with

PH₃(aq) + H⁺(aq)  → PH⁺₄ (aq)

Therefore, the net ionic equation for the reaction of hydrochloric acid with phosphine is PH₃(aq) + H⁺(aq)  → PH⁺₄ (aq)

Carbon dioxide in the air dissolves in rain as it falls to Earth. This results in the formation of carbonic acid, a weak acid. Explain why the student blowing into test tube B is similar to the process of forming slightly acidic rain.

Answers

Explanation:

Acid rain :

Acid rain is also known as acid deposition. It may be defined as a form of precipitation of the acidic components like nitric acid or sulfuric acid and fall to the earth surface from the atmosphere.

In the context, the student doing the experiment blows air in to the test tube B containing chalk dipped in water is similar to the process of acidic rain as it results in the formation of a weak carbonic acid when the carbon dioxide present in the air mixes with the chalk in the form of calcium carbonate.

Carbon dioxide reacts with water to from carbonic acid which dissociated into hydrogen ion and hydrogen carbonate ion.

Diffrentiate between atoms and ions.

Answers

Hello. What is an Atom?
The smallest unit of matter. It is indivisible and consists of neutrons, electrons and protons. Atoms can take part in chemical reactions. Combination of atoms together forms molecule. Always the number of protons and electrons are equal. Independent life may or may not be feasible within a solution. Nucleus of the atom is formed by protons and neutrons. Surrounding the nucleus are the electrons.

What is an Ion?
Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions. If an atom is charged electrically it is considered an ion. If an atom contains maximum number of electrons than protons, then it is called anion. If an atom contains maximum number of protons than electrons, then it is called cation. Independent existence in a solution. When an atom gains or loses electrons, ion is formed. Hope it helps

Explain how NOTHING is ZERO, but ZERO is more than NOTHING?

Answers

Answer:

Nothing can be zero, but zero isn't nothing. If someone asks you if you have money and you say "I've got nothing!" when you actually don't have a cent, then you have zero money. However, zero is a number, so it itself is something, therefore more than nothing. So technically, you do have something.

When zero is on a number line, you could classify it as nothing, but it is the number between 1 and -1. Hypothetically speaking, if you took the zero away, wouldn't the number line be the same?

Zero isn't positive or negative. The number zero on a graph, or in a coordinate can tell you where something is. Zero can be a word to describe if something is existent, or non-existent.

Calcium carbide ( CaC2) reacts with water to produce acetylene (C2H2) as shown in the unbalanced reaction below: CaC2(s)+H2O(g)->Ca(OH)2(s)+C2H2(g). How many grams of H2O are required to completely react with 82.4g of CaC2

Answers

Answer:
46.3g H2O

Explanation:
start by balancing it: CaC2(s) + 2H2O(g) -> Ca(OH)2(s) + C2H2(g)

then use factor label method to solve

82.4g CaC2 x (1 mol CaC2/64.10g CaC2) x (2 mol H2O/1 mol CaC2) x (18.016g H2O/1 mol H20) = 46.3g H2O

The given reaction can be balanced as follows: CaC2 + 2H2O → Ca (OH)2 + C2H2. Grams of water required to completely react with 82.4 g of CaC2 is 46.28 g.

What is a balanced reaction?

In balanced reaction, the number of each and every element on both side is balanced. In the given reaction to balance the number of H and O, add 2 to H₂O so that, all the species will be equal in number on both side.

Now, as per the balanced reaction, 2 moles of water is required to reacts with 1 mole of CaC2.

Mass of one mole of water = 18 g/mol.

                                   2 mole = 36 g

Mass of one mole of CaC2 = 64.09 g/mol

Thus 36 g of water is required to react with 64.09 grams of calcium carbide. Mass of water required to react with 82.4 g of calcium carbide is calculated as follows:

Mass of water = (36 g×82.4 g)/64.09 g = 46.28 g

Hence, 46.28 grams of water is required to completely react with 82.4 g of calcium carbide.

Explanation:

The acceleration of an object given it's mass and it's net force can be found by using the formula

[tex]acceleration = \frac{force}{mass} \\ [/tex]

From the question

force = 60 N

mass = 12 kg

a) 1.0000
b) 1.000

d) 1.0

Answers

I am pretty sure it’s d, 1.0 hope that helps!

To find the difference between 1.0051 and 5.1 x 10⁻³, subtract the second number from the first number from its decimal form.Thus, the correct option is A.

First, convert 5.1 x 10⁻³to decimal form:

5.1 x 10⁻³ = 0.0051 is the decimal form of the given number 5.1 x 10⁻³.

Then subtract the 2 numbers that is,0.0051 from 1.0051:

1.0051 - 0.0051 = 1.0000 which has 4 digits after the decimal.

So, the difference between  the two numbers 1.0051 and 5.1 x 10⁻³ is 1.0000.

Thus,the correct option is a) 1.0000 which is the difference between 1.0051 and 5.1 x 10⁻³.

Answers

Answer:

A. 8.8 g.

B. 5.3 g.

C. 449 g.

Explanation:

A. Determination of the mass of CO2.

Mole of CO2 = 0.2 mole

Molar mass of CO2 = 12 + (2×16)

= 12 + 32

= 44 g/mol

Mass of CO2 =?

Mole = mass /Molar mass

0.2 = mass of CO2 /44

Cross multiply

Mass of CO2 = 0.2 × 44

Mass of CO2 = 8.8 g

B. Determination of the mass of Na2CO3.

Mole of Na2CO3 = 0.05 mole

Molar mass of Na2CO3 = (2×23) + 12 + (3×16)

= 46 + 12 + 48

= 106 g/mol

Mass of Na2CO3 =?

Mole = mass /Molar mass

0.05 = mass of Na2CO3 /106

Cross multiply

Mass of Na2CO3 = 0.05 × 106

Mass of Na2CO3 = 5.3 g

C. Determination of the mass of Fe(OH)2.

Mole of Fe(OH)2 = 5 moles

Molar mass of Fe(OH)2 = 55.8 + 2(16 + 1)

= 55.8 + 2(17)

= 55.8 + 34

= 89.8 g/mol

Mass of Fe(OH)2 =?

Mole = mass /Molar mass

5 = mass of Fe(OH)2/89.8

Cross multiply

Mass of Fe(OH)2 = 5 × 89.9

Mass of Fe(OH)2 = 449 g.
