Answer:

23 g sodium

Explanation:

In chemistry, one mol (1mol) of a substance equals Avagadro's number or constant (6.02 × 10^23 atoms/particles/molecules).

According to this question in which the mass of different elements were given, the mass of the element that equals 6.02 × 10^23

Using the formula; mole = mass/molar mass

- Sodium = 23g/23g/mol = 1mol

- Krypton = 42g/84g/mol = 0.5mol

- Carbon = 24g/12g/mol = 2mol

- Pottasium = 78g/39g/mol = 2mol

Therefore, from the above illustration, it can be observed that only 23g of sodium contains 1 mol, hence, 23g sodium contains 6.02 × 10^23 atoms.

Answer:

To support the body, protect the organs, produce blood cells, and store calcium.

Assuming the reaction is complete, there should be no limiting reactant remaining after a reaction. This is because the limiting reactant, by definition, is "the reactant that is completely used up in a reaction."

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.

Explanation:

radiation is energy that comes from a source. (travels through the speed of light)

Answer:

The answer is 1.5 atm

Explanation:

Answer:

4 valence electrons

Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining

Answer:

The numer of valence electrons is defined as the number of electrons present in the outer most shell of the atom.So, in the case if selenium, there are 6.

Do a quick conversion: 1 moles Potassium Chloride = 74.5513 gram using the molecular weight calculator and the molar mass of KCl.

Answer:Static electricity can be created by rubbing one object against another object.

Explanation: This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge

Answer:

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Answer:pu-239

Explanation:

Pu-239 is regarded as the radioisotope requires long-term storage as the method of disposal, to protect living things from radiation exposure over time

Disposal of radioactive nuclear waste is often regarded as a problem.

The waste sources are:

Disposal of bomb-grade plutonium is often difficult.

The longer lived isotopes are:

The storage of the longer lived elements is through containment for the next several thousand of years.

The control or management of radioactive waste is a hard, multifaceted procedure.
