What is empirical formula of N306?

Answer:

No

Explanation:

In order for glucose to be produced inside the mixture, photosynthesis has to take place. The photosynthetic process requires a series of steps within an organelle called the chloroplast. The chloroplast contains the chlorophyll and other enzymes that are necessary for photosynthesis.

Once the chlorophyll is isolated, it becomes separated from the enzymes necessary for the completion of photosynthesis, and the process is truncated. When light is shined on the mixture, the majority would instead be lost as heat while some cause the chlorophyll molecules to glow.

Answer:

4.9 x 10²²hockey pucks

Explanation:

Given parameters:

Number of moles of hockey  = 0.0814moles

Unknown:

Number of pucks there = ?

Solution:

A mole of a substance is made up of Avogadro's number of particles.

Therefore;

       1 mole of hockey pucks will contain 6.02 x 10²³ hockey pucks

       0.0814 mole of hockey pucks will contain :

                              0.0814 x 6.02 x 10²³ = 4.9 x 10²²hockey pucks

Answer:

decomposition reaction

Explanation:

The reaction equation is given as:

      _Ca(OH)₂  →   _CaO    +   _H₂O

This reaction is a decomposition reaction in which a single reactant breaks down to give two or more products.

To balance the equation, we assign variables a, b and c, then we use a mathematical approach to solve the problem;

          aCa(OH)₂  →   bCaO    +   cH₂O

Conserving Ca : a = b

                    O:  2a  = b + c

                   H:   2a = 2c

let a  = 1, b = 1 , c = 1

Explanation:

Hi for this one u just need to remember and use the equation.

[tex]moles = \frac{mass}{mr} [/tex]

then u find mr of potassium which is 39.1.

then u do

[tex] \frac{20}{39.1} [/tex]

you get the answer as 0.5115 write ur answer to 3 significant figures which will be 0.512 moles .

Explanation:

Given parameters:

Number of atoms of Sucrose  = 5.25 x 10²⁹atoms

Unknown:

Number of moles  = ?

Solution:

To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.

             6.02 x 10²³ atoms makes up 1 mole of an atom

             5.25 x 10²⁹ atoms will contain = [tex]\frac{5.25 x 10^{29} }{6.02 x 10^{23} }[/tex]  = 872093.02moles

Answer:

554.13 grams

Explanation:

The mass of 5.82 mol of MgCl2 is 552.9g. Details about how to calculate mass can be found below.

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.

According to this question, there are 5.82 moles of MgCl2. The mass is calculated thus:

molar mass of MgCl2 = 24 + 35.5(2) = 95g/mol

mass of MgCl2 = 95g/mol × 5.82 moles

mass of MgCl2 = 552.9g

Therefore, the mass of 5.82 mol of MgCl2 is 552.9g.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{3.01 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{3.01}{6.02} = 0.5 \\ [/tex]

Answer:

All measurements have a degree of uncertaintyregardless of precision and accuracy. This is caused by two factors, the limitation of the measuring instrument (systematic error) and the skill of the experimenter making the measurements (random error).

Answer:

This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

Explanation:

The atomic number is the number of protons  ( p + ) . In a neutral atom, the number of electrons  ( e − )  equals the number of protons. Mass number is the sum of the protons and neutrons  ( n 0 )  of a particular isotope. If you have mass number and atomic number, subtract the atomic number from the mass number to get the number of neutrons.  ( Mass number ) − ( atomic number ) = number of neutrons .

There are:

9 protons

9 electrons

10 neutrons

Fluorine is the element in question, as its atomic number is  9 . You would name this particular isotope using the mass number. It would be called fluorine-19.

The nuclear or isotopic notation would be  19 9 F
