What are some similarities and differences between physical and chemical weathering

2 answers:

4 0

Similarities:
they both made sediment into soil
they both form the earth
they both made sediments have cracks

differences:
physical is reliant usually on contact with atmospheric condition

chemical transforms rocks into sediments while physical only breaks it down

chemical uses chemical reactions

(a brainliest would be appreciated)

compressibility - is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change. (D)

Flammability - ability of a chemical to burn or ignite, causing fire or combustion. (B)

Heat of Combustion - The amount of heat released per unit mass or unit volume of a substance when the substance is completely burned. (A)

Reactivity - the state or power of being reactive or the degree to which a thing is reactive (C)

Hope this helps!!

Examples 36

brilliants [131]

2x = 350- x

3x = 350

x = 350/x

therefore,

x = 116.67cm.

so, (350 - x)cm³ = (350- 166.67)cm³ = 233.33cm³

Hence distance covered by gas A is 116.67cm that by B is 233.33cm

Determine the grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

irina [24]

There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

<h3>What is the mass of a substance?</h3>

The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.

To determine the energy from the 8g of carbohydrate, we have:

= 8g × 4 kcal/g (the corresponding calories of food type)

= 32 kcal

The energy from 2g of fat = 2g × 9 kcal/g

= 18 kcal

The energy from protein is calculated as:

= 140 kcal - 32 kcal - 18 kcal

= 90 kcal

The required mass of the protein in grams is:

$\mathbf{= 90 \ kcal \times \dfrac{1}{4 \ kcal }}$

= 22.5 grams

Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.

You are given two acidic solutions of equal concentration and volume: HCl (aq) and HF (aq). Which solution would dissociate more

GREYUIT [131]

Answer:

HCl will dissociate more fully and produce more H₃O⁺ ions.

Explanation:

HCl is strong acid and it dissociate fully and produce more H₃O⁺ ions as compared to the HF.

Although H-F is stronger bond as compared to the HCl but stability of product also count, and fluorine ions F⁻ which are formed after dissociation are not more stable as Cl⁻ ions.

Both F⁻ and Cl⁻ are carried -1 charge, but in case of chloride ions negative charge is spread over large surface area while in case of fluorine it is restricted to small surface. Thus F⁻ are becomes unstable.

Thus in dissociation equilibrium is shifted to wards HF and cause lower dissociation.
