In physics, the force of attraction between two objects is gravitational force.<span>Isaac Newton's law of universal gravitation defines the concept of gravitational force, stating that a gravitational attraction exists between all objects.
Hope this helps!! :D</span>
The number of Na atoms in the reactants = 2
<h3>Further explanation</h3>
Every chemical reaction involves compounds that can act as reactants or products
The reactants will react to produce products
The reactants are usually written on the left side of the reaction, while the products on the right side of the reaction
Reaction
2 NaCl + H₂SO₄ → 2 HCl + Na₂SO₄
The element with atomic number 11 = Na(Natrium)
The number of atoms of the element that reacts or is produced can be seen from the reaction coefficient and the number of atoms in the compound
Na in NaCl = 1 atom
From equation, cofficient for NaCl = 2, so number of atoms of Na=2 x 1 = 2
The most common allotropes are:-
White phosphorus
Red phosphorus
The red one is an intermediate phase between white and violent phosphorus.
The bacteria in nasty environment undergoes multiple fission.
<h3><u>Explanation</u>:</h3>
The bacteria is a unicellular prokaryotic organisms that are found in each and every places of the world. They can survive in extremes of temperatures and pH. They can save themselves through special processes in the extreme climates.
The bacteria undergoes multiple fission in these climates. They cover themselves up with a strong and tough capsule inside which they undergo several Binary fissions. This leads to the formation of multiple cells enclosed with a capsule.
With the return of the favourable climate, the capsule rupture and these newly formed cells come out.
