H2C2O4, also written as (COOH)2, is Ethandioic acid, and, as evident by the name, is an acid, and not a base
Ca(OH)2 and KOH, Calcium Hydroxide and Potassium Hydroxide, respectively, are bases when dissolved in water, as they are able to release OH- ions.
Hydrogen Iodide, HI, when dissolved in water, is a strong acid. So, that is also not a base.

<u>Answer:</u> The correct answer is Ca(OH)_2\text{ and }KOH

<u>Explanation:</u>

Acids are defined as the chemical species that produces hydrogen ions on dissolving in water.

Bases are defined as the chemical species that produces hydroxide ions on dissolving in water.

We are given:

Chemical compounds having chemical formulas CH_3COOH,Ca(OH)_2,KOH\text{ and }HI

CH_3COOH is an organic acid and it produces CH_3COO^-\text{ and }H^+ ions

Ca(OH)_2 is a base and it produces Ca^{2+}\text{ and }OH^- ions

KOH is a base and it produces K^{+}\text{ and }OH^- ions

HI is an acid because it produces H^+\text{ and }I^- ions

Hence, the correct answer is Ca(OH)_2\text{ and }KOH

Place the following in order of increasing molar entropy at 298 K.
Genrish500 [490]

Answer:

SO < CO2 < C3H8

Explanation:

Entropy refers to the degree of disorderliness of a system. The standard molar entropy of a substance refers to the entropy of 1 mole of the substance vunder standard conditions.

The molar entropy depends on the number of microstates in the system which in turn depends on the number of atoms in the molecule.

C3H8 has 11 atoms and hence the highest number of microstates followed by CO2 having three atoms and least of all SO having only two atoms.

HELP.....From the information presented in the activity series of metals below (4 metals included), answer the following questio
san4es73 [151]

Answer:

a)there would be no reaction

Explanation:

The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.

In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.

 

Would aluminum replace magnesium to form a new compound or would there be no reaction?

Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.
