8 0

Answer:

<h3>the true statement is an atom contains the same number of electron and proton</h3>

Explanation:

let us see the behaviour of the sub atomic particles

  1. nutrons and protons found in the nucleus of an atom
  2. an atom have the same number of electron and proton but they have different charge
  3. nutron is chargeless particle
  4. most mass of the atom concentrated in the nucleus of an atom
  5. electrons have almost 0 mass from an atom
  6. mass of proton and mass of nutron are equvalent or almost equal

there are many properties of subatomic particles i have listed some of them above .

AnnyKZ [126]

Answer:

E

Explanation:

A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap

Sugar is used to fill a box that has a volume of 200 cm3. The sugar weighs 316 grams. What is the density of sugar? (Ignore the
lions [1.4K]

<u>Answer:</u> The density of sugar is 1.58g/cm^3

<u>Explanation:</u>

To calculate the density of a substance, we use the equation:

Density=\frac{Mass}{Volume}

We are given:

Mass of sugar = 316 g

Volume of box = 200cm^3

Putting values in above equation, we get:

\text{Density of sugar}=\frac{316g}{200cm^3}\\\\\text{Density of sugar}=1.58g/cm^3

Hence, the density of sugar is 1.58g/cm^3

A gas has a mass of 3.82 g and occupies a volume of 0.854 L. The temperature in the laboratory is 302 K, and the air pressure is
Rzqust [24]

The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

<h3>How to calculate molar mass?</h3>

The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.

However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:

PV = nRT

Where;

  • P = pressure
  • V = volume
  • n = number of moles
  • T = temperature
  • R = gas law constant

1.04 × 0.854 = n × 0.0821 × 302

0.888 = 24.79n

n = 0.888/24.79

n = 0.036mol

Molar mass of gas = 3.82g/0.036mol

Molar mass = 106.66g/mol

Therefore, the molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.
