Answer:

This question is incomplete but the completed question is below

Which process takes place when large rocks crumble due to oxidation?

A) Erosion

B) Deposition

C) physical weathering

D) chemical weathering

The correct option is D

Explanation:

Weathering can simply be defined as the breakdown of the top surface of rocks. <u>From this definition, it can be deduced that the question describes a type of weathering</u>. Weathering can be of two types; Physical weathering and chemical weathering.

Physical weathering is caused by physical components of the environment such as temperature, water and some activities of living organisms. Physical weathering does not alter the chemical composition of the rock. A <u>chemical weathering</u> is caused by a reaction between the components of the rock and another substance. This type of weathering <u>involves a chemical reaction (for example oxidation)</u> which leads to the breakdown of the rock.

4. The picture shows a full moon.

Anuta_ua [19.1K]

Answer:

A full moon occurs when the Moon appears as a complete circle in the sky.

Explanation:

- We see it as a full orb because the whole of the side of the Moon facing the Earth is lit up by the Sun's rays.

- The moon shows no visible light of its own, so we only see the parts of the moon that are lit up by other objects.

Write a balanced chemical equation for the standard formation reaction of liquid acetic acid hch3co2.

Afina-wow [57]

The balanced chemical equation for the standard formation reaction of liquid acetic acid is given as ,

$2C(gr) +2H_{2} (g) +O_{2} (g)$ → $CH_{3} COOH(l)$

The reaction that form the products from their elements in their standard state is called formation of reaction .The acetic acid consist C , H , and O , So, determine their standard state . Carbon is graphite at 25°C and 1 atm , whereas hydrogen and oxygen are diatomic gases . Hence , we start with unbalanced reaction.

$C(gr) +H_{2} (g) +O_{2} (g)$ → $CH_{3} COOH(l)$

The balanced chemical equation for the standard formation reaction of liquid acetic acid as,

$2C(gr) +2H_{2} (g) +O_{2} (g)$ → $CH_{3} COOH(l)$

The combustion of liquid acetic acid is given as,

$CH_{3} COOH(l) + 2O(g)$ → $2CO_{2}((g) +2H_{2} O(l)$ ΔH =-873
