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

hydrated CoCl2 is a deep purple color. After being heated for a long time, it turns into its anhydrous form, which is sky blue.
ch4aika [34]

Answer:

Physical change

Explanation:

It is a physical change because a physical change involves alteration in physical properties or appearance in color, sizes e.t.c but no new substances is formed. From the question, CoCl2 undergo a physical change because it's physical property which is color changed , its composition is not altered or no new substances is formed during the reaction.

Is a gold necklace a element, compound, or a mixture
Akimi4 [234]

Answer:

It would be an element my dear.

--------------------------------------------------------------------------------------------

Pure gold is an element. That is, it is not a combination of other materials. However, gold used in jewelry is usually a “mixture”, called an alloy mixed with other metals to harden it, to change the color as in copper makes the pink or rose gold that is currently enjoying great polarity.
