Answer: In a compound with molecular formula X_2Y_3 ,the valency of Y and X are 2 and 3 respectively.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

The given compound is X_2Y_3 where X and Y combine and their oxidation states or valencies are exchanged and written in simplest whole number ratios. Thus the oxidation state or valency of X is 3 and that of Y is 2.

Name 2 different types of local winds and explain each.please.
marshall27 [118]
1. Planetary Winds:

The winds blowing through­out the year from one latitude to another in response to latitudinal differences in air pressure are called “planetary or prevailing winds”. They involve large areas of the globe.

4. Periodic Winds:

Periodic winds change their direction periodically with the change in season, e.g., Monsoons, Land and Sea Breezes, Mountain and Valley Breezes.

Which gas law (choices are Charles' Law, Gay-Lussac's Law, or Boyle's Law) explains each scenario:
Sedaia [141]

Explanation:

Air bags help lessen injuries in an automobile crash is application of Boyle's law:

Boyle's law states that at constant temperature, the volume of given mass of a gas is directly proportional to the pressure changes.

According to this law, the volume of the air bag will increase. The bag will become bigger as a result of decrease in the gas pressure in the bag.

The bag was packed with gases under high pressure and their volume decreases appreciably. After a collision, pressure reduces and the gas expands.

helium balloon decreases in size when you put it into a freezer

A can of spray paint will explode if tossed into a fire

Both are application of Charles's law:

 According to this law "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".

The helium balloon decreases in size because the temperature is lowered. The particles will keep tending towards a state of rest.

A can spray paint explodes because the gas in it will keep expanding as the temperature increases in a fire.
