How many moles of atoms are in 50 atoms Ba

Answers

moles of atoms in 50 atoms of barium are 301.15 × 10^23

We may determine how many chemicals or particles are included in one mole using Avogadro's number.Chemistry's fundamental building block is an atom. It is the smallest fraction of matter into which electrically charged particles cannot be released. It is also the smallest piece of substance with chemical element-like characteristics.A mole of any substance is equal to 6.023 x 10^23, or Avogadro's number. Additionally, it is employed to express concentrations in terms of moles per litre or molecular weight.The number of atoms in exactly 12 grammes of pure carbon-12 is the value of a mole.Chemical element barium has the chemical symbol Ba and atomic number 56. In group 2, it is the fifth element.

1 mole of substance = 6.023 x 10^23

so in 50 atoms of Ba = 50 × 6.023 × 10^23

= 301.15 × 10^23

Therefore, moles in 50 atoms of Ba is 301.15 × 10^23.

What is the significance of scientific notation?

The main reason for converting numbers to scientific notation is to make calculations involving unusually large or small numbers easier. Because zeros are no longer used to set the decimal point, all digits in a scientific notation number are significant, as demonstrated by the examples below.The primary reason for the importance of scientific notation is that it allows us to convert very large or very small numbers into much more manageable sizes. It is much easier to work with these numbers when they are written in scientific notation.

In this problem, there are two significant figures. The final answer should also have two significant figures.

All scientific notation should have a non-zero number, followed by a decimal point to it's right, followed by remaining significant figures after that. The first non-zero number is 1, so the decimal point should follow the 1.

Moving the decimal to the right decreases the power of ten. The current number can be expressed as

The substrate concentration of this enzyme operates at one‑quarter of its maximum rate is = 0.333.

What is the relationship between Km and substrate concentration?

In practice, Km is the concentration of substrate that allows the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate and requires a higher concentration of substrate to achieve Vmax."

Because Km is a constant, increasing the substrate concentration has no effect on it. The substrate concentration Km corresponds to the substrate concentration at which the reaction rate of the enzyme-catalyzed reaction is half of the maximum reaction rate Vmax.

How many molecules of water are required for the hydrolyzation of a polymer that is 22 monomer-long cellulose molecule?.

Answers

21 molecules of water are required for the hydrolyzation of a polymer that is 22 monomer-long cellulose molecule.

For hydrolyzation of 22 monomer-long cellulose molecule, 21 molecules of water are required. As for three monomer polymer there are 2 bonds so we require two water molecules.

The process of hydrolyzation is a step-by-step reaction in which-

The first step is the condensation of one glucose molecule to produce a 2 monomer-long chain, which releases one molecule of water.

The second step is reaction between the 2 monomer-long chain with other glucose molecule, which release an extra molecule of water.

These steps are repeated until 21 condensation reactions occurs, to give 22 monomer-long cellulose molecule.

The OH group from first monomer of the glucose unit and H group from second monomer is removed in the form of water molecules, when polymer bond is formed.

The reaction is known as the condensation reaction. It is referred to as the loss of water in a chemical reaction.

Therefore, 22 monomer long cellulose molecule indicates 21 reactions of condensation with release of 21 molecules of water.

Explanation:

The formula for finding a object's density is:
D = M/V, which means Density equals Mass divided by Volume.

In this case, our mass is 12.5 grams, our volume is 2.7mL, and our density is the unknown we are solving for.

One important thing to keep in mind when finding density is the type of measurements used. Fortunately in this case, we are dividing grams by ml, which have a 1:1 conversion rate.

To find our answer, we just divide 12.5 by 2.7 to get:

Answers

If there is a usual soda pop that contains 360 mL then the number of cans that can be filled from 2.0 L bottle are 5.5 pop cans.

Amount present in one soda can = 360 mL

Convert 2.0 L into mL

1 L = 1000 mL

2.0 L = 2.0 x 1000 mL

So, the total amount = 2000 mL

Number of can using 360 mL = 1

Question 1: The periodic table is arranged by various patterns. Is there a pattern with regard to ionic charge? In three to five sentences, explain your reasoning and provide specific examples.

Question 1 Answer: Negative ions increase in magnitude from right to left, whereas positive ions increase in magnitude from left to right. This is due to the fact that the left side of the periodic tale contains metals whereas the right side does not. As negative-charged electrons are always produced by metals, the element will become more positive when they are lost.

Question 2: Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. In three to five sentences, identify the direction of the change, and give two reasons for the change.

Question 2 Answer: The atomic number of sodium is 11, while neon is 10. Since neon has an outer shell made entirely of electrons, it doesn't interact with the other elements. The extra electron in sodium is located in the outer shell and there is one extra proton as well. By either losing one electron or gaining seven more, it might fill that shell. Since it will start losing that electron, sodium is a much more reactive element then neon.

Answers

Positive ions grow in magnitude from left to right, while negative ions grow in magnitude from right to left.

What are ions?

Any atom or collection of atoms with one or more positive or negative electrical charges is known as an ion.

The periodic table shows that there are more valence electrons on the right than the left. The maximum amount of ionic charge that an element can hold fluctuates as the number of valence electrons rises.

Second, metals on the periodic table's left side primarily produce positively charged ions. These ions get stronger over time, increasing in size.

The negative charges on the ions that non metals on the right side of the periodic table produce have a diminishing magnitude over time.

Heat and pressure form common rocks, but dramatic changes in their shape correspond to weathering because weathering breaks rocks from large structures into small mineral particles.
