<u>Answer:</u> Four ionic compounds formed will be
<u>Explanation:</u>
Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.
We are given:
Two cations having formulas
Two anions having formulas
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
The four ionic compounds are:
- When iron ion and chloride ions combine, it results in the formation of compound. This is named as iron (II) chloride.
- When iron ion and oxide ions combine, it results in the formation of compound. This is named as iron (II) oxide.
- When chromium ion and chloride ions combine, it results in the formation of compound. This is named as chromium (IV) chloride.
- When chromium ion and oxide ions combine, it results in the formation of compound. This is named as chromium (IV) oxide.
Hence, the four ionic compounds formed will be
Answer:
exothermic reaction
when compounds dissolve they produce heat hence a chemical reaction that produces heat is known as endothermic reaction.
The definition of authentic is something that is original or true and not a copy of anything else.

Answer:
Basicity is the number of replacable hydrogens of an acid in aqueous or basic medium. Three –OH are present (attatched with P atom ) . These three –OH produces three H+ ions. Number of replaceable hydrogen ions in H3PO4 is 3
Answer:
• 1.62432 moles of nitrogen
• Tire Pressure: 2.74 * 10⁵ Pa
• The tires will burst
• Pressure: 244 kPa
Explanation:
• We can determine the number of moles of nitrogen using the formula pV = nRT, where p = pressure, V = volume, n = number of moles, R = gas constant, and T = absolute temperature.
Now remember we have our initial pressure in kilopascals so let's convert to pascals (249 pascals). The volume is given in liters, so let's convert into m². And the initial temperature is given in Celsius ⇒ our absolute temperature in Kelvins.
Respectively the moles of nitrogen in each tire should be:
• We can solve this part similarly. All our values will be the same, besides the temperature, as we have to consider both the initial and final temperature here.
-
• The text mentions that the tires will burst when the internal pressure reaches 269kP. From part #2 we know that the final pressure will be, in kilopascals, 274kP. As 274 > 269, the tires will burst in Death Valley.
• We would want the final temperature = breaking pressure. Therefore,
