Answer:<em> A transfer of electrons occurs when fluorine and calcium react to form an ionic compound. This is because calcium is in group two and so forms ions with a two positive charge. ... A pairs of shared electrons makes one covalent bond. The compound formed is known as a molecule***</em>
The correct option is (a) H₂S : SO₂ = 2 : 2 and O₂ : H₂O = 3 : 2
<h3>What is molar Ratio ?</h3>
Molar ratio also known as stoichiometry is the ratio in which the reactants and products are either formed or reacted in the given equation
the balanced equation is as follows ;
2H₂S + 3O₂ --> 2SO₂ + 2H₂O
molar ratio can be determined by the coefficients of the compounds in the balanced reaction.
coefficient is the number in front of the chemical compound
coefficients for the compounds in this reaction are as follows ;
- H₂S - 2
- O₂ - 3
- SO₂ - 2
- H₂O - 2
therefore, correct option is (a) H₂S:SO₂ = 2:2 and O₂:H₂O = 3:2

Answer is: cesium sulfide.
Formula for ionic compound is: Cs₂S.
Ionic compound <span>electrically </span>neutral, cesium has charge +1 (2· (+1) = +2) and sulfur has charge -2.
Cesium sulfide is whide powder, soluble in water, pyrophoric in dry air, reductant.
No atoms are lost or made during the chemical reaction so the total mass of the products is equal to the total mass of the reactants. In an atom, protons and neutrons contribute to the mass and since the number of them doesn’t change, the mass doesn’t either.
Answer: Chyme
Explain: Chyme passes from the stomach to the small intestine. Further protein digestion takes place in the small intestine.
