Complete a write up about the elements in Ammonia and explain how the elements bounded to create the new substance.

Answers

Answer 1

Answer:

Explanation:

Ammonia consist of nitrogen and hydrogen.

Chemical equation:

N₂ + H₂    →   NH₃

Balance chemical  equation:

N₂ + 3H₂    →   2NH₃

We can see that nitrogen and hydrogen react with each other and from ammonia.

Nitrogen is present in group 5A.  The atomic number of nitrogen is 7.  Its atomic mass is 14 amu.  It has 5 valence electron.

Electronic configuration:

N₇ = 1s² 2s² 2p³

we can see there are five electron in outer most shell. Thus, nitrogen needs three more electrons to complete the octet.  When it combine with other atoms it gain three electron from them

While hydrogen is present in group 1A. It has one valence electron. In ammonia (NH₃) when nitrogen react with hydrogen it gain three electrons thus three atoms of hydrogen combine with one atom of ammonia because one hydrogen atom can share only one electron. Covalent bond is formed between nitrogen and hydrogen and new substance formed is called ammonia.

If a sample of copper is 215g, how many moles of copper atoms are in the sample?

Answers

Answer:

3.38 moles.

Explanation:

The following data were obtained from the question:

Mass of copper (Cu) = 215 g

Number of mole of copper (Cu) =...?

The number of mole of copper (Cu) in 215 g can be obtained as follow:

Mass of copper (Cu) = 215 g

Molar mass of copper (Cu) = 63.55 g/mol

Number of mole of copper (Cu) =...?

Mole = mass /Molar mass

Mole of Cu = 215/63.55

Mole of Cu = 3.38 moles

Therefore, 3.38 moles of copper (Cu) is present in the sample.

What mass of ethanol will All
a 250.0 ml container if its
density is 0.789 g/ml?

Answers

Answer:

The answer is 197.25 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 250 mL

density = 0.789 g/ml

So we have

mass = 250 × 0.789

We have the final answer as

197.25 g

Which of the following is NOT a characteristic of a compound?
A. has different properties from the elements that formed it
B. pure substance made of two or more elements
C. can be represented by a chemical formula
D. different samples have different properties

Answers

Answer:

I think it's D

sorry if I'm wrong.

Explanation:

Options that are not characteristics of compound in the question is D. different samples have different properties.

A compound can be regarded as a substance which is formed by chemical  combination of two or more elements.Examples of compound are water ( H2O), Sodium chloride ( NaCl)

Some of the properties of a compound are;

A compound will always has a different properties which is different from the properties of each of the elements making up the compound.A compound are formed as a result of  two or more elements that combined chemically.A compound can be identified with its chemical formula.

Therefore, option D is correct because a compound will only has its own properties not that

If a football is 625 mL volume and 0.64 g/mL density what is the mass

Answers

the mass is 400

explanation

the formula for density is density equals mass divided by volume so you plug in .64 for the density and 625 for the volume. .64= m/625. to solve for mass you would multiply both sides by 625 to get the mass

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps

Answers

The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂

Further explanation  

Equalization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]

1. Coefficient

KClO₃ ⟶ aKCl + bO₂

2. Equation

K ⇒ left =1, right=a ⇒a=1

Cl⇒ left =1, right=a ⇒a=1

O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5

The equation turns into :

KClO₃ ⟶ KCl + 1.5O₂

multiplied by 2

2KClO₃ ⟶ 2KCl + 3O₂

Answers

Answer:

Explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.

Which symbol and unit of measurement are used for resistance?
symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R

Answers

Answer:

Unit of resistance is Ω (Omega).

Explanation:

The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :

V = IR

R is resistance

Its unit is Omega and it is represented by Ω.

The unit of the electrical resistance is ohm Ω

The symbol of resistance is R.

Hence Option A) Symbol: R, Unit : Ω is the correct answer

What is resistance?

Resistance is simply the measure of the opposition to current flow in an electrical circuit.

Ohm’s law states that the potential difference between two points is directly proportional to the current flowing through the resistance.

V = I × R

Where;

V is the voltage or potential difference. I is the current.R is the resistance.

The unit of the electrical resistance is ohm Ω

The symbol of resistance is R.

Hence Option A) Symbol: R, Unit : Ω is the correct answer

Find the percent of oxygen in CaClO3)2 Show your work

Answers

So in calcium chlorate, there is one calcium, 2 chlorines, and 6 oxygens. To find the percent of oxygen in the compound, find the weight of the oxygen and divide it by the total weight of the compound:

weight of oxygen (95.94g/mol) / weight of entire compound (206.98g/mol)
= 0.4635

Finally, to convert this to a percentage you multiply it by 100

0.4635 x 100 = 46.35% Oxygen by mass

True

Explanation:

There are two ways to tell elements apart from each other: the atomic number or the number of protons. The atomic number tells the number of protons in the element.

For example:

There are two given elements. One has 3 protons and an atomic number of 3 while the other has 7 protons and an atomic number of 7. Which one is Lithium?

Lithium has an atomic number of 3, which means it has three protons, which means Lithium is the one with 3 protons.
