Answer:

Balanced chemical equation:

2Na + Cl₂ → 2NaCl

Explanation:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.

Chemical equation:

Na + Cl₂ → NaCl

Balanced chemical equation:

2Na + Cl₂ → 2NaCl

Ionic compound:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

True or false: If the pressure is constant, as the temperature of a gas increases the volume increases.

DerKrebs [107]

Answer:

False.

Explanation:

Because if there is more space in the container for the gas to move, there is less pressure. There would be a decrease in the pressure

<h3>Explanation:</h3>

<u>Step 1: Define</u>

5.26 mol Fe₂(SO₄)₃

<u>Step 2: Identify Conversions</u>

Molar Mass of Fe - 55.85 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Fe₂(SO₄)₃ - 2(55.85) + 3(32.07) + 12(16.00) = 399.91 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 5.26 \ mol \ Fe_2(SO_4)_3(\frac{399.91 \ g \ Fe_2(SO_4)_3}{1 \ mol \ Fe_2(SO_4)_3})$
Multiply/Divide: $\displaystyle 2103.53 \ g \ Fe_2(SO_4)_3$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

2103.53 g Fe₂(SO₄)₃ ≈ 2100 g Fe₂(SO₄)₃

Does sound have color? why do you have this opinion (base your answer on wavelengths)

mash [69]

Answer:

Yep. Many of the sounds we associate with white noise are actually pink noise, or brown, or green, or blue. In audio engineering, there's a whole rainbow of noise colors, each with its own unique properties, that are used to produce music, help relaxation, and describe natural rhythms like the human heartbeat.

A cube has a mass of 42 grams and a volume of 15 cubic centimeters. What is it’s density?

deff fn [24]

Answer:

2.8g/cm³

Explanation:

Given parameters:

Mass of cube = 42g

Volume of cube = 15cm³

Unknown:

Density of the cube = ?

Solution:

Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:

Density = $\frac{mass}{volume}$

So;

Density = $\frac{42}{15}$ = 2.8g/cm³
