What is produced when an acid reacts with a metal?a. Salt and hydrogen
c. Water and base
b. Carbon and salt
d. Carbon dioxide and water

Answers

Answer 1

Answer:

Answer: Option (a) is the correct answer.

Explanation:

When an acid reacts with a metal then there occurs formation of a salt along with liberation of hydrogen gas.

For example, $Zn + 2HCl \rightarrow ZnCl_(2) + H_(2)$

Here, Zn (zinc) is the metal which when added to hydrogen chloride acid them it leads to the formation of salt zinc chloride and hydrogen gas.

This type of reaction is also known as single displacement reaction.

Thus, we can conclude that salt and hydrogen is produced when an acid reacts with a metal.

Answer 2

Answer: The answer should be A. The metal will replace the hydrogen as the cation which will result in the a salt and hydrogen gas. An example is Mg reacting with HCl which produces MgCl₂ (salt) and H₂ (hydrogen).

I hope this helps. Let me know if anything is unclear.

Answers

The bond between Br atoms in an Br2 molecule is concealment and is formed by sharing of two valence electrons.

Final answer:

The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.

Explanation:

The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.

In a covalent bond, atoms share electrons to complete their outer electron shell. In the case of a Br2 molecule, each Br atom has 7 valence electrons and needs 1 more electron to achieve a stable octet arrangement, so they share one pair of electrons to achieve this.

The bond between Br atoms in a Br2 molecule is covalent and is formed by the sharing of two valence electrons.

which of the molecules listed below directly donates a nitrogen atom for the formation of urea during the urea cycle?

Answers

Aspartate directly donates a nitrogen atom from the formation of urea during the urea cycle.
The argininosuccinate synthase reeaction links aspartate and citrulline via the amino group of aspartate and provides the second nitrogen of urea.

20 Which term is defined as a measure of the disorder of a system?(1) heat (3) kinetic energy
(2) entropy (4) activation energy

Answers

Entropy is the term defined as a measure of the disorder of a system. This occurs mainly when the thermal energy is not available for the mechanical things.

Heat is a measure of energy in a medium
Kinetic energy is a measure of energy in an object that's resulting in movement
Activation energy is the amount of energy required to start a chemical reaction
Entropy is a measure of disorder in a system
The answer is Entropy
