Which of the following is the conjugate acid of H2P04- ?
A. HAP04
O B. PO 3-
O C. HP04-2
O D. H3PO4

Answers

Answer:

phosphoric acid H3PO4

The conjugate acid of H₂PO⁴⁻ is H₃PO₄. Therefore, option D is correct.

A conjugate acid is a species that is formed when a base accepts a proton (H⁺). It is the species that is one proton (H⁺) more acidic than the original base.

The base is the species that can accept a proton (H⁺), and the conjugate acid is the species that is formed when the base accepts the proton. The conjugate acid has one additional proton compared to the base.

Conjugate acids play an important role in acid-base reactions as they are formed when bases accept protons, and they can donate protons in subsequent reactions to regenerate the original base.

Which action would cause the chair to move to the left?
A. Applying 100 N of force to the chair from the left
B. Applying 200 N of force to the chair from the left
O c. Applying 200 N of force to the chair from the right
O D. Applying 100 N of force to the chair from the right

Answers

In order to overcome static friction, a force greater than 175 N would need to be applied to the chair, so we can eliminate A and D. Since you want to move the chair to the left, you’d have to push from the right, so the correct answer is
C) applying 200 N of force to the chair from the right

What is chemical change?

Chemical change is a reaction in which breaking and forming of new bonds take place. One molecule completely converted to totally different molecule. The number of atoms remains same

One famous example of chemical change is the rusting of iron. The color, odor and arrangements of atoms in products are very much different from reactant. Chemical change are mostly irreversible in nature.  Physical change is just opposite of chemical change. Phase change is an example of physical change.

Find the percent of oxygen in CaClO3)2 Show your work

Answers

So in calcium chlorate, there is one calcium, 2 chlorines, and 6 oxygens. To find the percent of oxygen in the compound, find the weight of the oxygen and divide it by the total weight of the compound:

weight of oxygen (95.94g/mol) / weight of entire compound (206.98g/mol)
= 0.4635

Finally, to convert this to a percentage you multiply it by 100

0.4635 x 100 = 46.35% Oxygen by mass

If a sample of copper is 215g, how many moles of copper atoms are in the sample?

Answers

Answer:

3.38 moles.

Explanation:

The following data were obtained from the question:

Mass of copper (Cu) = 215 g

Number of mole of copper (Cu) =...?

The number of mole of copper (Cu) in 215 g can be obtained as follow:

Mass of copper (Cu) = 215 g

Molar mass of copper (Cu) = 63.55 g/mol

Number of mole of copper (Cu) =...?

Mole = mass /Molar mass

Mole of Cu = 215/63.55

Mole of Cu = 3.38 moles

Therefore, 3.38 moles of copper (Cu) is present in the sample.
