Why are most anions basic in H2O? Give formulas of four anions that are not basic.
AVprozaik [17]

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.

Which of the following would be considered a compound?<br> He<br> CI<br> NaCl<br> B
kobusy [5.1K]

Answer:

NaCl

Explanation:

because He which is helium gas its an element alone,

Cl which is chlorine is a single element,

B which is Boron and its a single element,

but NaCl which is simply called table sugar is the combination between Na, sodium and Cl, chlorine , so its called a compound not an element.

4. The reaction of silver nitrate and potassium bromide yields silver bromide and potassium nitrate. If
Hatshy [7]

Answer:

1.) AgNO₃

2.) 0.563 moles AgBr

Explanation:

The limiting reagent is the reagent that is used up completely during a reaction. It can be identified by calculating which reactant produces the smallest amount of product. This can be done by determining the number of moles of each reagent (via molarity conversion). and then converting it to moles of the product (via mole-to-mole ratio).

AgNO₃ (aq) + KBr (aq) ---> AgBr (s) + KNO₃ (aq)

Molarity (M) = moles / liters

100 mL = 1 L

AgNO₃

45.0 mL / 100 = 45.0 L

1.25 M = ? moles / 0.450 L

? moles = 0.563 moles

KBr

75.0 mL / 100 = 0.750 L

0.800 M = ? moles / 0.750 L

? moles = 0.600 moles

In this case, there is no need to use the mole-to-mole ratio because all of the coefficients are one in the reaction (the amount of the limiting reagent used is the same amount of product produced). Since AgNO₃ produces the smaller amount of product, it is the limiting reagent.

In the writing of ionic chemical formulas, what factor is "crossed over" in the crossover rule?
Levart [38]

Ionic compounds are formed by the complete transfer of electrons between the atoms.  The atom which gains electron(s) forms anion whereas loss of electron(s) results in the formation of cation.  They are bonded to each other by electrostatic force of attraction between the negatively and positively charged atoms.


While writing the ionic chemical formula for binary ionic compound the rules are:

  • Writing the chemical symbol of the metals and non-metals involved in the compound formation.
  • The charge i.e. the absolute value of oxidation number of each metal is written on respective atoms.
  • The charge i.e. the absolute value of oxidation number are cross-multiplied that is the charge of first ion becomes the subscript of second ion and vice versa.

Hence, in the writing of ionic chemical formulas, the value of each ion's charge is "crossed over" in the crossover rule.
