the number of protons will tell you what elements it is. T or F plzz help​

Answers

Answer:

True

Explanation:

There are two ways to tell elements apart from each other: the atomic number or the number of protons. The atomic number tells the number of protons in the element.

For example:

There are two given elements. One has 3 protons and an atomic number of 3 while the other has 7 protons and an atomic number of 7. Which one is Lithium?

Lithium has an atomic number of 3, which means it has three protons, which means Lithium is the one with 3 protons.

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.

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

explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps

Answers

The balance of chemical equation : 2KClO₃ ⟶ 2KCl + 3O₂

Further explanation  

Equalization (balance) of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

[tex]\tt KClO_3\Rightarrow KCl+O_2[/tex]

1. Coefficient

KClO₃ ⟶ aKCl + bO₂

2. Equation

K ⇒ left =1, right=a ⇒a=1

Cl⇒ left =1, right=a ⇒a=1

O ⇒ left = 3, right = 2b ⇒3=2b, b = 1.5

The equation turns into :

KClO₃ ⟶ KCl + 1.5O₂

multiplied by 2

2KClO₃ ⟶ 2KCl + 3O₂

The maximum amount of statie friction between this chair

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

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.
