Answer:

4, 16,

Explanation:

SI2 is sulphur diiodide. Sulphur is in group sixteen (six valence electrons) while iodine is in group 17(seven valence electrons).

Since there are two iodine atoms and one sulphur atom, the molecule has twenty valence electrons. Out of these twenty valence electrons, only four are bonding electrons. The other sixteen electrons include the four nonbonding electrons found on sulphur and the twelve non bonding electrons found on the two iodine atoms having six nonbonding electrons each.

Luda [366]
If you’re referring to he red stuff- the liquids can be ethanol, toluene, kerosene, or isoamyl acetate. They’re transparent so they’re made more visible with red dye. (So I’d guess the answer is ethanol)

Answer:

Бардык белгилүү авиация мыйзамдарына ылайык, аары учуу мүмкүнчүлүгү жок. Канаттары өтө эле кичинекей, семиз денесин чече албайт. Албетте, аары баары бир учат. Себеби аарылар адам мүмкүн эмес деп эсептеген нерсеге маани бербейт.

When substances react chemically to create a new substance, will that new substance have the same physical and chemical properti
Makovka662 [10]

Answer:

When a chemical reaction occur, new substances are formed. The physical and chemical properties of new substances are different from initial substance.

Explanation:

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible.

These changes occur due to chemical reactions.

These may not be observed with naked eye.

Examples:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood .

Boiling of egg: that change the chemical composition of protein in the egg.

Physical change:

The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.

These changes were reversible.

They have same chemical property.

These changes can be observed with naked eye.

Examples:

Water converting to Ice.

Water converting to gas.

In this water molecule remain the same only they rearrange themselves that change its state of mater not composition.
