Answer:

Hydrogen and oxygen are both nonmetals.

Explanation:

From general knowledge, we know that hydrogen and oxygen are both non metallic gases at room temperature. But if we did not know this, the question telling us that they bond together covalently should give us a very strong hint that they are non metallic substances because that's how non metals bond with each other.

If an acid is made from the anion SO42-, what would it's formula be?
KatRina [158]

<u>Answer:</u> The chemical formula of the compound formed is H_2SO_4

<u>Explanation:</u>

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

We are given:

An anion having chemical formula SO_4^{2-} named as sulfate ion

This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.

Hence, the chemical formula of the compound formed is H_2SO_4

Assume an original volume of blood of one deciliter (100 ml). if 5 ml of oxygen diffuses into the blood, 100 ml will be its final volume.

A tissue is made up of white blood cells, platelets, red blood cells, and other elements suspended in a liquid. Blood transports waste away and delivers nutrients and oxygen to the tissues. The entire amount of fluid moving through the heart's arteries, capillaries, veins, venules, and chambers is referred to as blood volume. Red blood cells (erythrocytes), white blood cells (leukocytes), platelets, and plasma are the elements that give blood volume.

The amount of water and sodium ingested, expelled by the kidneys into the urine, and lost through the digestive system, lungs, and skin determines blood volume. The amounts of salt and water that are consumed and excreted vary greatly.

For a certain reaction, Kc = 2.76×103 and kf= 6.54×10−4 M−2⋅s−1 . Calculate the value of the reverse rate constant, kr, given th
riadik2000 [5.3K]

Answer:

2.37x10⁻⁷ M⁻².s⁻¹

Explanation:

For a generic reversible reaction:

A + B ⇄ C + D

Kf is the constant of the formation of the products (C and D), Kr is the constant of the formation of the reactants (A and B), and Kc is the general equilibrium constant, which is:

Kc = Kf/Kr

2.76x10³ = 6.54x10⁻⁴/Kr

Kr = 6.54x10⁻⁴/2.76x10³

Kr =  2.37x10⁻⁷ M⁻².s⁻¹
