Which agents cause both chemical and physical weathering

1 answer:

8 0

Weathering is the process by which rocks are broken down by either physical or chemical means. Physical weathering involves physical factors that cause mechanical break down of rocks while chemical weathering involves chemical reactions between the contents of the rocks and other factors such air (oxygen). Agents of weathering are the factors that cause or enhance both physical and chemical weathering. Some of these factors cause both physical and chemical weathering these includes water and temperature.

Choose the FALSE statement.

Mariana [72]

Answer:

C. The half-life of C-14 is about 40,000 years.

Explanation:

The only false statement from the options is that the half-life of C-14 is 40,000yrs.

The half-life of an isotope is the time it takes for half of a radioactive material to decay to half of its original amount. C-14 has an half-life of 5730yrs. This implies that during every 5730yrs, C-14 will reduce to half of its initial amount.

All living organisms contain both stable C-12 and the unstable isotope of C-14
The lower the C-14 compared to the C-12 ratio in an organism, the older it is.

How many moles of chlorine (Cl) atoms are in a sample of 1.72 × 1022 atoms?

Ainat [17]

<span>1mole of Cl atoms contain the Avogadro's number 6x10 exp 23(10 to the power of 23)
there for xmoles of Cl atoms is contained in 1.72x1022atoms
xmoles =1.72x1022 divided by 6x10exp 23
2.93 exp -23moles(2.93 x10 to the power of -23)

Hope It helped Let me know if did!!!!

A 5.00 mL sample of hydrochloric acid is titrated with 0.1293 M ammonia (a base). If the titration required 28.15 mL of ammonia,

Sladkaya [172]

Answer:

1. C = 0.73 M.

2. pH = 0.14

Explanation:

The reaction is the following:

HCl + NH₃ ⇄ NH₄⁺Cl⁻

From the titration, we can find the number of moles of HCl that were neutralized by the ammonia.

$n_{a} = n_{b}$
