How many grams of Na2So4 would be formed if 0.75 moles of NaOH reacted?
Nata [24]

Answer:

\boxed{\text{53 g }}

Explanation:

You don't give the reaction, but we can get by just by balancing atoms of Na.

We know we will need the partially balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

M_r:                                 142.04  

             2NaOH + … ⟶ Na₂SO₄ + …  

n/mol:      0.75

1. Use the molar ratio of Na₂SO₄ to NaOH to calculate the moles of NaF.

Moles of Na₂SO₄ = 0.75 mol NaOH × (1 mol Na₂SO₄/2 mol NaOH

= 0.375 mol Na₂SO₄

2. Use the molar mass of Na₂SO₄ to calculate the mass of Na₂SO₄.

Mass of Na₂SO₄ = 0.375 mol Na₂SO₄ × (142.04 g Na₂SO₄/1 mol Na₂SO₄) = 53 g Na₂SO₄

The reaction produces \boxed{\text{53 g }} of Na₂SO₄.

In an acid-base neutralization reaction 43.74 ml of 0.500 m potassium hydroxide reacts with 50.00 ml of sulfuric acid solution.
timama [110]
The   neutralization reaction between  potassium  hydroxide  and  sulfuric  acid   is  as  follows
2KOH  +  H2SO4 ---> K2SO4  +  2H2O

number  of   moles  of  KOH=  (43.74  x  0.500)/  1000=  0.02187 moles

the  reacting ratio  of  KOH  to H2SO4  is  2:1  therefore  the   moles  of  H2SO4  is  =  0.021187/2=  0.01094 moles

concentration(molarity) = ( 0.01094/50 ) x 1000=  0.2188M

What energy does satellite use
MAXImum [283]
Hello!

The Sun is the main source of providing energy for the satellites. There are solar panels on the satellites to get solar energy from the sun. The sun does provide solar energy and since it's the main source of energy for the satellites, that leaves you with your answer which is solar energy.

I hope this helped!

I am, yours most sincerely,
