Answer:

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over 300 naturally-occurring isotopes are known.

Answer:

The answer is "\bold{CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)}"

Explanation:

When HCI is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:

CH_3COONa\ (aq) + HCl\ (aq)\longrightarrow CH_3COOH\ (aq) + NaCl\ (aq)\\\\

 In this, the CH_3COOH is a weak acid so, it not completely dissociated.

CH_3COONa \ (aq) \ \ and \ NaCl were strong electrolytes they are completely dissociated.

The HCl is a strong acid so, it is completely dissociated So, the net ionic equation is:

CH_3COO^{-} \ (aq) + H^{+}\ (aq) \longrightarrow CH_3COOH \ (aq)

Luda [366]
<h3>Further explanation </h3>

In general, some people equate mass and weight.

Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)

Steps that can be taken  to find the mass :

  • 1. Weigh graduated cylinder (empty)
  • 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml
  • 3. Weigh again graduated cylinder + poured alcohol
  • 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first step

Alina [70]

Answer:

N - 1s²2s²2p³

Explanation:

Nitrogen is located in the p-block of the periodic table (groups 13-18) and is on the 2nd period.

The 2nd period tells us the principal energy level (a quantum number) is n = 2. Therefore, it must have already filled up the 1s sublevel.

The groups 13-18 on period 2 tells us that the 2s sublevel is also filled.

Nitrogen is located in Group 15. That means that there are 3 electrons that have filled the 2p sublevel, out of a possible 6.

Therefore, our electron configuration is 1s²2s²2p³

2p³ (Shorthand Config)

[He] 2s²2p³ (Noble Gas Config)

This is an example of Innovation.

<h3>What is an Innovation?</h3>

Innovation is the application of concepts in a way that results in the creation of new products or services or enhances the provision of existing ones. Innovation is defined as "a new or altered entity realizing or dispersing value" by ISO TC 279 in the standard ISO 56000:2020. Others have different definitions, but they all place an emphasis on the novelty, development, and dissemination of concepts or technologies.

The creation of more efficient goods, procedures, services, technology, works of art, or business models, which innovators then make available to consumers, governments, and society as a whole, is a common way that innovation occurs. Innovation and invention are not the same thing, but they are related.
