Drag the tiles to the correct locations. Each tile can be used more than once, but not all tiles will be used. One or more locat

ions will remain empty. Carbonyl sulfide has the chemical formula COS. Carbon has four valence electrons, and oxygen and sulfur each have six valence electrons. Complete the Lewis structure for this covalent compound.

Answer:             xx           xx

                         xxOxxCxxSxx

Explanation:

Sorry for the structure, but since Oxygen and Sulfur belong to group of six they want to share two electrons. Carbon belonging to group four wants to share 4 since its valence shell has four electrons.

Therefore the resulting Lewis structure is linear (like carbon dioxide) with two pairs of lone pairs in each O and S atoms and 0 lone pairs in carbon and two double bond.

When a piece of zinc metal is carefully placed in a beaker of strong acid, bubbles form on the surface of the metal and begin to
kati45 [8]

Answer:

A.  a new substance is being produced.

Explanation:

The bubbles most likely indicates that a new substance is being produced by this reaction. In essence, we describe this sort of change as chemical change.

In a chemical change, new substances are usually produced. They are accompanied by the evolution or absorption of energy.

The reaction of Zinc with a strong acid to produce bubbles on the surface of the metal indicates a chemical change and the formation of a new kind of substance.

Take for example, let zinc reacts with hydrocholoric acid, HCl;

   Zn         +      2HCl      →    ZnCl₂     +     H₂

Since Zn is higher than Hydrogen in the activity series, it will displace it from HCl and liberate hydrogen gas as a product. This will cause the bubbles observed in the reaction.

This is a chemical change and new products have been formed.

B and D are wrong because they are both physical changes.

C is wrong because no information about such is provided by the problem statement.

So, when a piece of zinc metal combines with a strong acid, a new kind of substance is produced.

Read the following chemical equation. Mg(s) + H+ Cl− → Mg2+ Cl− + H2 What most likely happens during this reaction?
spin [16.1K]

Answer:

Magnesium loses two electrons.

Explanation:

  • As clear from the reaction Mg converted from <em>Mg(s) to Mg²⁺</em>, so Mg converted from the oxidation state (0) to (2+).

<em>∴ Mg losses two electrons.</em>

  • Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.

<em>So, the correct choice is Magnesium loses two electrons.</em>
