Answer:

0.075 moles of product formed.

Explanation:

Given data:

Number of moles of oxygen = 0.30 mol

Number of moles of oxygen = 0.15 mol

Number of moles of product formed = ?

Solution:

Chemical equation:

4Na + O₂       →    2Na₂O

Now we will compare the moles of Na₂O with oxygen and sodium.

                Na           :           Na₂O

                  4            :              2

                  0.15       :          2/4×0.15 = 0.075 mol

                O₂           :           Na₂O

                  1            :              2

                  0.30       :          2/1×0.30 = 0.6 mol

Less number of moles of Na₂O are produced by sodium thus it will limit the yield of  Na₂O and act as limiting reactant while oxygen is in excess.

The addition of phosphate to a chemical compound is called A. glycolysis. B. oxidation. C. reduction. D. phosphorylation.
stich3 [128]

Answer:

Option (D)

Explanation:

Phosphorylation can be simply defined as the addition of a phosphate group to an organic and inorganic molecule. This process helps in regulating the processes that occur in the cells. It leads to the growth and development of cells and this process is efficiently carried out with the help of enzymes like kinase. It also plays an important role in transferring the signals within the cells, synthesis, and functioning of proteins within the cells, and storing as well as releasing of energy.

Thus, the correct answer is option (D).

What three tests must all theories pass to be considered a "proven" theory?
VladimirAG [237]

 In order to become a scientific theory the three categories that it must pass are the following: 


1) Can the phenomena be recreated in a laboratory setting? 


2) Can variables be changed, yet still result in like observations? 


3) Is the phenomena truly natural or was it the result of a man-made force enacting upon it?

If a person had the values for an objects density and volume, what value can be calculated
zavuch27 [327]

Hello there! With the values of density and volume, you would be able to find the object's mass.

Density is found by dividing the mass by the volume, so you could place in the values of the density and the volume to get the mass.

For example:

500 = mass/10

The 500 being density and 100 being volume. You would use simple math rules and multiply 10 by 500, and you'd get 5000, therefore using the density and volume values and giving you the mass.

I hope I could help you and have a great day!

nignag [31]

Answer:

Both b/c a chemical formula tells you how many and a sketch formula shows how they are bonded together.

Molecular formulas show how many atoms of each element one molecule of a compound contains. Note: Ionic compounds are generally crystalline solids with high melting points. Other compounds, however, have very different properties.
