342.14 g/mol
Molar mass of Al= 26.98
Molar mass of S=32.06
Molar mass of O=16.00
(26.98)2+(32.06+(16.00×4))3=342.14
A neutral particle of an atom is located at the nucleus.
<h3>What are electron cloud?</h3>
Electrons are those negatively charged particles that are found revolving round an atom.
Electron cloud is defined as the model of an atom in which the atom consists of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.
A neutral particle is a nucleus because the nucleus of an atom is made up of neutral particles found within the nucleus of an atom which doesn't contain any charges.
An atom is defined as the smallest and indivisible part of an element which can take part in a chemical reaction.
An atom is made up of nucleus which consists of the proton (which is positively charged) and the neutron (which bears no charges at all).
Therefore, a neutral particle can be said to be an electron cloud.

Answer:
At room temperature water, milk and lemon juice are liquid while oxygen is gas.
Explanation:
The substances are liquid at room temperature if their normal melting points are lower than room temperature.
The melting point of oxygen is -218°C and boiling point is -189 °C that's why it is gas at room temperature.
Oxygen is diatomic gas O₂.
It is colorless and odor less.
The liquid and solid oxygen are pale blue in color.
It reactive with all other elements and form oxides except noble gases.
In diatomic form, under normal conditions oxygen is not harmful but in the from of ozone O₃ it is harmful if inhaled.
It is readily dissolve in a cold water.
Answer:
Explanation:
n CaCO3 = mass / m.wt
= 500 /( 40 + 12 + 16x 3)
= 5 mole
n CaO = 5 moles ( from the balanced equation we have 1:1 moles )
mass of CaO = nCaO X m.wt
5 x( 40 +16 )
= 280 grams
