How many liters of 4.0 NaOH solution will react with 1.8 mol H2SO4

Chemistry
1 answer:
wlad13 [49]3 years ago
8 0

Answer:

0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.

Explanation:

2NaOH(aq)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)

According to reaction, 1 mole of sulfuric acid reacts with 2 moles of sodium hydroxide.

Then 1.8 moles of sulfuric acid will react with:

\frac{2}{1}\times 1.8 mol=3.6 mol moles of NaOH.

Molarity of NaOH = 4.0 M

Moles of NaOH= n = 3.6 mol

Volume of NaOH = V

M=\frac{n}{V(L)}

V=\frac{n}{M}=\frac{3.6 mol}{4.0 M}=0.9 L

0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.

The reaction can be described using the equation: 2C2H25O24CO22H2O. How much C2H2is needed to react with 68.1 g of O2to produce
Sophie [7]

Answer:

22.13g

Explanation:

We'll begin by writing a balanced equation for the reaction. This is illustrated below:

2C2H2 + 5O2 —> 4CO2 + 2H2O

Next, we'll calculate the mass of C2H2 and O2 that reacted from the balanced equation. This is illustrated below:

Molar Mass of C2H2 = (12x2) + (2x1)

= 24 + 2 = 26g/mol

Mass of C2H2 that reacted from the balanced equation = 2 x 26 = 52g

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 that reacted from the balanced equation = 5 x 32 = 160g

Now, we can obtain the mass of C2H2 that will react with 68.1g of O2 as follow:

From the balanced equation above,

52g of C2H2 reacted with 160g of O2.

Therefore, Xg of C2H2 will react with 68.1g of O2 i.e

Xg of C2H2 = (52x68.1)/160

Xg of C2H2 = 22.13g

Therefore, 22.13g of C2H2 is needed to react with 68.1g of O2

How does temp affect the phase of a substance
notka56 [123]

Answer:

state of matter

Explanation:

so take water for example, water has a melting point and a boiling point right? So if it's below 0 degrees, then it's in its solid phase. If the temperature is above 0 degrees, then the water starts to melt into its liquid phase. Then when the temperature is above 100 degrees, water starts to boil and become its gas phase. This is the same for all substances. The only difference is different substances have different melting and boiling points so the numbers will be different depending on your substance. hope this helped!
