Ms ( mass of solute): 33,6g
mss (mass of solution): 33,6+192g = 225,6g

C = ms/mss × 100%
C = 33.6/225.6 × 100%
C = 14,89% ≈ 14,9%

A gas at 127०C and 10.0 L expands to 20.0 L. What is the new temperature in Celcius? (HINT: You need to convert to Kelvins solve

Snowcat [4.5K]

Answer:

526.85K

Explanation:

Based on Charles's law, the volume of a gas is directly proportional to absolute temperature. The formrula is:

V₁ / T₁ = V₂ / T₂

Where 1 represents the initial state and 2 the final state of the gas

Using the values of the problem:

V₁ = 10.0L

T₁ = 127°C + 273.15K = 400.15K

V₂ = 20.0L

Thus, replacing in the formula:

10.0L / 400.15K = 20.0L / T₂

T₂ = 800K

In Celsius:

800K - 273.15 = 526.85K

Like several other bonds, carbon-oxygen bonds have lengths and strengths that depend on the bond order. Draw Lewis structures fo

aniked [119]

The order of increasing C-OC−O bond length is:

a < c < b < e < d

Therefore, the order of increasing bond strength is:

d < e < b < c < a

d< e < b < c < a

<h3>What is bond length?</h3>

The distance between the centers of two atoms that are covalently connected is known as the bond length. The number of bound electrons determines the bond's length (the bond order). The greater the attraction between the two atoms and the shorter the bond length are, the higher the bond order.

The average distance between the nuclei of two bound atoms in a molecule is referred to as bond length or bond distance in molecular geometry. It is a transferrable characteristic of a bond between atoms of fixed kinds that is comparatively independent from the other components of the molecule.

Bond length and bond order are related; the shorter the bond is when more electrons are involved in its production.

How do invertebrates affect the oxygen levels of compost and soil?.

Digiron [165]

Invertebrates affect the oxygen levels of compost and soil by reducing it.

<h3>How respiration works?</h3>

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

Every living organism undergoes the process of cellular respiration and make use of oxygen molecules in the process.

This means that invertebrates will make use of the oxygen gas present in compost and the soil for respiration, hereby reducing it.
