How many moles of potassium hydroxide are needed to completely react with 2.94 moles of aluminum sulfate according to the follow
fiasKO [112]

Answer:- Third choice is correct, 17.6 moles

Solution:- The given balanced equation is:

Al_2(SO_4)_3+6KOH\rightarrow 2Al(OH)_3+3K_2SO_4

We are asked to calculate the moles of potassium hydroxide needed to completely react with 2.94 moles of aluminium sulfate.

From the balanced equation, there is 1:6 mol ratio between aluminium sulfate and potassium hydroxide.

It is a simple mole to mole conversion problem. We solve it using dimensional set up as:

2.94molAl_2(SO_4)_3(\frac{6molKOH}{1molAl_2(SO_4)_3})

= 17.6 mol KOH

So, Third choice is correct, 17.6 moles of potassium hydroxide are required to react with 2.94 moles of aluminium sulfate.

Identify the missing information for each atom or ion. Note that the atoms and ions are not necessarily neutral.
zimovet [89]

Answer:

Number of neutrons: 44

Number of protons: 34

Number of electrons: 36

Explanation:

The atomic number of Se (Selenium) is 34

Mass number is 78

Number of neutrons = mass number - atomic number = 78 - 34 = 44

Number of protons is the same as the atomic number

Number of protons = 34

Selenium ion has a charge of -2. This means it accepts two more electrons

Number of electrons = atomic number + 2 = 34 + 2 = 36
