How many moles of atoms are in 9.00 g of 13c?

Answers

0.629 moles will be present in moles of atoms are in 9.00 g of 13 carbon atom.

What is a mole?

One mole of any substance is the amount of the substance which contain 6.023 × 10²³ atoms or molecule if the substance is atomic or molecular in nature and known as gram atomic mass.

Number of atoms in carbon is 9.00 grams and isotope are 13C,

Number of moles = weight of substance / mass of substance

Substituting the value in formula,

    Number of moles = 9.00 grams / 13

     Number of moles = 0.629 moles

Therefore, 0.629 moles will be present in moles of atoms are in 9.00 g of 13 carbon atom.

#SPJ2
The atomic weight of 13C should be pretty close to 13.0. (If you have the exact mass, use it in the problem.) So, 9.00 g / 13.0 g/mol = 0.692 moles Therefore, the answer should be 0.692 moles are in 9.00 g of 13C.

What you understand by macrocylic effect in coordination chemistry

Answers

Explanation:

The macrocyclic effect in coordination chemistry refers to the enhanced stability of metal complexes that have a macrocyclic ligand. A macrocyclic ligand is a ligand that forms a ring around the metal ion, forming a macrocyclic complex. This structure increases the enthalpy of the complex, making it more thermodynamically stable. In other words, the macrocyclic effect increases the stability of a metal complex by making the ligand more difficult to remove. This effect is especially important in biological systems, where macrocyclic ligands play a key role in many enzymatic reactions.

Why is it important to know what temperature scale is being used in a given situation?

Answers

It depends, for example, it is quite important to know the Kelvin scale (i.e 0 degrees Celsius is 273 K and -273 degrees Celsius is 0 K ) when dealing gases. But I don't know other situations where you would need to know other temperature scales.

Hope this helps and also if you are using Fahrenheit 1 Fahrenheit is -17.22 degrees Celsius 

When 1-iodo-1-methylcyclohexane is treated with NaOCH2CH3 as the base, the more highly substituted alkene product predominates. When KOC(CH3)3 is used as the base, the less highly substituted alkene predominates. Give the structures of the two products and offer an explanation.

Answers

Answer:

See explanation

Explanation:

In this case, we have 2 types of reactions. CH_3CH_2ONa is a strong base but only has 2 carbons therefore we will have less steric hindrance in this base. So,  the base can remove hydrogens that are bonded on carbons 1 or 6, therefore, we will have a more substituted alkene (1-methylcyclohex-1-ene).

For the  KOC(CH_3)_3 we have more steric hindrance. So, we can remove only the hydrogens from carbon 7 and we will produce a less substituted alkene (methylenecyclohexane).

See figure 1

I hope it helps!

Describe the relationship between predator and prey in a balanced ecosystem. Please help I'll give brainliest.

Answers

Answer:

predators are controlling the population of the species who are below them in the food pyramid . Also if the population of the preys decrease it will alternatively reduce the predator population .therefore the predator prey relationship balance an eco system.
