Answer:

Here's what I get

From the scattering experiments, Rutherford concluded that the positive charge was concentrated in the nucleus of the atom.

This contradicted the plum pudding model, which assumed that the positive charge was uniformly distributed throughout the atom.

What is the percent of hydrogen by mass in CH4O?<br> (H:1.00 amu, C: 12.01 amu, O: 16.00 amu)
cricket20 [7]

The mass percent of hydrogen in CH₄O is 12.5%.

<h3>What is the mass percent?</h3>

Mass percent is the mass of the element divided by the mass of the compound or solute.

  • Step 1: Calculate the mass of the compound.

mCH₄O = 1 mC + 4 mH + 1 mO = 1 (12.01 amu) + 4 (1.00 amu) + 1 (16.00 amu) = 32.01 amu

  • Step 2: Calculate the mass of hydrogen in the compound.

mH in mCH₄O = 4 mH = 4 (1.00 amu) = 4.00 amu

  • Step 3: Calculate the mass percent of hydrogen in the compound.

%H = (mH in mCH₄O / mCH₄O) × 100%

%H = 4.00 amu / 32.01 amu × 100% = 12.5%

The mass percent of hydrogen in CH₄O is 12.5%.

Answer:

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.

How many grams of NaOH are required to neutralize 700 mL of 3.0 M HCl?
sveta [45]

A gram of NaOH required to neutralize 700 ml HCL is <u>84 grams.</u>

Neutralization or neutralization is a chemical response in which an acid and a base react quantitatively with each different. I

Moles of solute = Molarity × Liters of solution

                           = 3 × 0.7 L

                          = 2.1 mole

The molar mass of NaOH = 40

mass of NaOH = 40 × 2.1 g

                        =<u> 84 gram.</u>

A neutralization response may be described as a chemical reaction in which an acid and base quantitatively react together to shape salt and water as products. In a neutralization response, there's a combination of H+ ions and OH– ions that form water.

A neutralization response is when an acid and a base react to shape water and salt and includes the mixture of H+ ions and OH- ions to generate water. The neutralization of a sturdy acid and robust base has a pH equal to 7.
