Answer:

As a result, electrolyte solutions readily conduct electricity. ... By contrast, if a compound dissociates to a small extent, the solution will be a weak conductor of electricity; ... Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. ... Explain why some molecules do not dissolve in water.

If 2.00 g of N2 occupies 1.25 L space, how many moles of N2
uranmaximum [27]

Answer:

n₂ =1.4 mol

Explanation:

Given data:

Mass of nitrogen = 2 g

Initial Volume occupy by nitrogen = 1.25 L

Final volume occupy by nitrogen = 25.0 L

Final number of moles = ?

Solution;

Formula:

V₁ / n₁ = V₂ / n₂

Number of moles of nitrogen:

Number of moles = mass/ molar mass

Number of moles = 2 g/ 28 g/mol

Number of moles = 0.07 mol

Now we will put the values in formula:

V₁ / n₁ = V₂ / n₂

n₂ = V₂× n₁ /V₁

n₂ = 25 L × 0.07 mol /  1.25 L

n₂ = 1.75 L. mol / 1.25 L

n₂ =1.4 mol

One agent of chemical weathering is _______________ which combines with water to form carbonic acid
ololo11 [35]
I believe the answer is carbon dioxide. Because when carbon dioxide and water combine in the atmosphere it forms a very weak acid called carbonic acid, which falls to the Earth's surface as precipitation.

Five pulses are generated every 0.112 s in a tank of water. What is the speed of propagation of the wave if the wavelength of th
DedPeter [7]

Answer:

The answer to the question is

The wave speed is 53.57 cm/s

Explanation:

The speed of a wave is the distance covered by the wave per unit time.

Wave speed is given by

v = f×λ

where v = The velocity of the wave

f = The wave frequency

λ = The wavelength of the wave

the speed v of the wave can also be expressed interms of the period as

v = λ/T

The freuency of the given wave is f = 5/(0.112 s) = 44.64 Hz and the wavelength is λ = 1.20 cm

Therefore the speed of the wave = 44.64 Hz × 1.20 cm = 53.57 cm/s

In an acid-base neutralization reaction 38.74 ml of 0.500 m potassium hydroxide reacts with 50.00 ml of sulfuric acid solution.
DaniilM [7]

Answer:

0.2 M.

Explanation:

  • For the acid-base neutralization, we have the role:

The no. of millimoles of acid is equal to that of the base at the neutralization.

<em>∴ (XMV) KOH = (XMV) H₂SO₄.</em>

X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),

M is the molarity.

V is the volume.

  • For KOH:

X = 1, M = 0.5 M, V = 38.74 mL.

  • For H₂SO₄:

X = 2, M = ??? M, V = 50.0 mL.

∴ M of H₂SO₄ = (XMV) KOH/(XV) H₂SO₄ = (1)(0.5 M)(38.74 mL)/(2)(50.0 mL) = 0.1937 M ≅ 0.2 M.
