Answer:

3.4\times 10^3 eggs are produces are in a month.

Explanation:

Quantity of eggs produced by the chicken in a month = 284 dozens

1 dozen = 12 eggs

Number of eggs in a month:

284 dozens = 284\times 12 eggs =3,408 eggs\approx 3.4\times 10^3 eegs

3.4\times 10^3 eggs are produces are in a month.

Calculate the Molarity of 89.94 g NaCl is dissolved in 1249 mL of solution.<br><br> e
Dmitriy789 [7]

Answer:

Molarity = 1.23 M

Explanation:

Given data:

Molarity of NaCl = ?

Mass of NaCl = 89.94 g

Volume of solution = 1249 mL ( 1249/1000 = 1.249 L)

Solution:

First of all we will calculate the number of moles of NaCl.

Number of moles = mass/molar mass

Number of moles = 89.84 g/ 58.5 g/mol

Number of moles = 1.54 mol

Molarity:

Molarity = Number of moles of solute / volume of solution in L

Molarity = 1.54 mol / 1.249 L

Molarity = 1.23 M

Write the empirical formula for at least four ionic compounds that could be formed from the following ions
andreyandreev [35.5K]

Answer:

NH₄CN,  NH₄IO₃,  Fe(CN)₃,  Fe(IO₃)₃

Explanation:

Cations (positively charged ions) can only form ionic bonds with anions (negatively charged ions). However, you can't just simply put one cation and one anion together to form a compound. Each compound needs to been neutral, or have an overall charge of 0. When cations and anions do not have charges that perfectly cancel, you need to modify the amount of each ion in the compound.

1.) NH₄CN

-----> NH₄⁺ and CN⁻

-----> +1 + (-1) = 0

2.) NH₄IO₃

-----> NH₄⁺ and IO₃⁻

-----> +1 + (-1) = 0

3.) Fe(CN)₃

-----> Fe³⁺ and CN⁻

-----> +3 + (-1) + (-1) + (-1) = 0

4.) Fe(IO₃)₃

-----> Fe³⁺ and IO₃⁻

-----> +3 + (-1) + (-1) + (-1) = 0
