If it takes 38.70 cm^3 of 1.90M NaOH to neutralize 10.30cm^3 of H2SO4 in a battery. What is the concentration of the H2SO4?

Answers

Answer:

3.57 M

Explanation:

The reaction that takes place is:

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

First we calculate how many NaOH moles reacted, using the given concentration and volume:

38.70 cm³ = 38.70 mL1.90 M * 38.70 mL = 73.53 mmol NaOH

Then we convert NaOH moles into H₂SO₄ moles, using the stoichiometric coefficients:

73.53 mmol NaOH * [tex]\frac{1mmolH_2SO_4}{2mmolNaOH}[/tex] = 36.765 mmol H₂SO₄

Finally we calculate the concentration of H₂SO₄:

36.765 mmol H₂SO₄ / 10.30 mL = 3.57 M

Answers

Answer:

Acids are sour in taste. Acids react with carbonates and hydrogen carbonates to form a salt, water, and carbon dioxide gas. Extremely active metals such as Potassium (K), Calcium (Ca), Sodium (Na), etc tend to explode when combined with acids. Weak Acids like Carbonic Acid doesn't act with any metal at all.

Explanation:

moles of NH₃ = 11.9g/17.03 g/mol = 0.699 mole

moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole

Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams

%Yield = Actual Yield/Theoretical Yield x 100%

= 18.5g/20.963g x 100% = 88.25%

Answer:

same process as last solution I did for you except the mole ratio isn't 1:1 here it is 2:1 so you diveide the moles of NH3 by 2 to get the urea moles

here I got 88.16% yield

What is the pH of a solution with a (H+] = 0.80 M? *Please round your answer to the appropriate number of significant figures. Your answer can be in standard notatic "e" in place of x10.*​

Answers

Answer:

The pH of a solution with a (H+] = 0.80 M is [tex]9.6 e^{-2}[/tex]

Explanation:

As we know

pH = -[log H+]

Substituting the value of H+ ion concentration in the above equation, we get -

pH = -log [0.80]

pH [tex]= -[-0.096] = 0.096 = 9.6 e^{-2}[/tex]

How many milliliters of 0.25M H2SO4 can be prepared from 57 mL of a 3.0M solution of H2SO4?

Answers

Answer:

Why ? Because 1 molecule of H2SO4 gives 2 H+ ions per molecule while only one H+ ion is required to neutralize 1 molecule of KOH. So, 1 molecule of H2SO4 can neutralize 2 molecules of KOH. Hence, we would require 525 ml of 0.03 M H2SO4 to neutralize 525 ml of 0.06 M KOH. How will we prepare 525 ml of 0.03 M H2SO4 ?

Explanation:

Now, we have 0.025 M H2SO4 and we do not know how much volume we have.

We will use the standard N1 X V1 = N2 X V2 for this calculation.

N1=0.025 M; V1=unknown; N2=0.03 M and V2=525 ml.

So V1= (0.03 X 525)/(0.025) = 630 ml.

According to the molar concentration, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case  of 2 solutions,it is calculated as, M₁V₁=M₂V₂ substitution gives V₁=3×57/0.25=684 ml.

Thus, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.

What is the ideal gas equation?

The ideal gas equation can be defined as an equation that describes the behavior of an ideal gas. This equation gives by the product of the volume and pressure is equal to the product of the moles of gas, gas constant, and absolute temperature.

The mathematical form of the ideal gas law is given as follows:

PV = nRT

Where n is the moles, V is the volume, R is the universal gas constant and P is the pressure.

The temperature of the N₂ , T =  0° C = 273 K

The pressure of the gas at STP, P = 1 atm

The value of the universal gas constant, R = 0.082 atm L/K mol

The number of moles of N₂, n = 0.881 mol

Fill in the values n, R, P, and T in the equation, and we get:

1 × V = 0.881 × 0.082 × 273

V = 19.72 L

why is atomic radi measured using the nuclues from 2 of the same atoms

Answers

Explanation:

Atomic radii is measured using the distance between nucleus of 2 atoms rather than the distance between the nucleus and outermost shell because:

- There is no clear/sharp boundary of the orbital. This is why it is called an electron cloud.

- Also, the exact location of the electron is not known. What is known is the probability of finding the electron there.

Due to this, it is not possible to measure the atomic radii precisely. That's why the distance between the nucleus of two atoms is used.
