Answer:

Communication skills are the abilities you use when giving and receiving different kinds of information. Some examples include communicating new ideas, feelings or even an update on your project. Communication skills involve listening, speaking, observing and empathising. It is also helpful to understand the differences in how to communicate through face-to-face interactions, phone conversations and digital communications like email and social media.

Consider the reaction:

Fofino [41]

The mass in grams of NH₃ produced from the reaction is 3.4 g

<h3>Balanced equation</h3>

We'll begin by writing the balanced equation for the reaction. This illustrated below:

N₂ + 3H₂ -> 2NH₃

From the balanced equation above,

1 dm³ of N₂ reacted to produced 2 dm³ NH₃

<h3>How to determine the volume of NH₃ produced</h3>

From the balanced equation above,

1 dm³ of N₂ reacted to produced 2 dm³ NH₃

Therefore,

2.24 dm³ of N₂ will react to produce = 2.24 × 2 = 4.48 dm³ of NH₃

<h3>How to determine the mass of NH₃ produced</h3>

We'll begin by obtained the mole of 4.48 dm³ of NH₃. Details below:

22.4 dm³ = 1 mole NH₃

Therefore,

4.48 dm³ = 4.48 / 22.4

4.48 dm³ = 0.2 mole of NH₃

Finally, we shall determine the mass of NH₃ as follow:

Molar mass of NH₃ = 17 g/mol
Mole of NH₃ = 0.2 mole
Mass of NH₃ =?

Mass = mole × molar mass

Mass of NH₃ = 0.2 × 17

Mass of NH₃ = 3.4 g

What happens when sodium and cholorine are mixed

tigry1 [53]

Answer:

The short of it is you would create salt.

Explanation:

If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.

AZX symbol of a cation with 13 neutrons

Svet_ta [14]

The AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+

AZX is a symbol which stands for;

A is the mass number
Z is the atomic number or the number of protons

X is the chemical symbol of the element

Note, cations are positively-charged ions having more protons than electrons due to loss of one or more electrons.

Sodium ion represented as Na+ is a cation which lost one electron. It has 13 neutrons and 11 protons.

But the mass number of an element, A is the sum of protons and neutrons of the element.

Thus, for Na+

A = 13 + 11 = 24

Z = 11

X = Na+

Therefore, the AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+

Toluene, C7H8, is used in the manufacture of explosives such as TNT (trinitrotoluene). A 1.500 g sample of liquid toluene was pl

dusya [7]

Answer:

There were 63.67 kJ liberated

If 1 mol of toluene was burned, there would be liberated 3906 kJ / mole

Explanation:

Step 1: Data given

Mass of the toluene sample = 1.500 grams

The temperature of the calorimeter rose from 25.000 °C to 26.413 °C

<em>Write the balanced chemical equation for the reaction in the calorimeter.</em>

C7H8(l) + 9O2(g) ⇒ 7CO2(g) + 4H2O(l)

<u>Step 2:</u> Calculate Q of the calorimeter

Q = C * Δt

Q = 45.06 kJ/ °C * ( 26.413 - 25)

Q =<u> 63.67 kJ </u>

<u>Step 3:</u> Calculate moles of toluene

Moles toluene = mass toluene / molar mass toluene

Moles toluene = 1.500 grams /92.14 g/mol

Moles toluene = 0.0163 moles

<u>Step 4:</u> Calculate energy per mole

energy per mole = 63.67 kJ / 0.0163 moles = 3906 kJ / mole

I have my chemistry EOC tomorrow, and I need to know how to calculate the molar mass of a compound. Specifically ones set up lik

yuradex [85]

Answer:

357.475

Explanation:

First you need periodic table and you have to look for mass

Fe = 3 x 55.845 = 167.535

P = 2 x 30.97 = 61.94

o = 4 x 2 so 8 oxygen = 8 x 16 = 128

add all and you get 357.475
