Answer:
A new element
Explanation:
As you add mopre and more protons and electrons and neutrons it keeps on crating new.
20.91200832 g of must be dissolved in 0.504 L of a solution to make a 0.56 M solution.
What is the molarity of a solution?
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.
Given data:
The volume of solution= 0.504 L
Molarity of = 0.56 M
Step 1: Calculating the mass of
Putting the given values in the equation.
Moles of solute = 0.28224
Molar mass of = 74.093 g/mol
Now, put the values in the formula.
Mass of =20.91200832 g
Hence, 20.91200832 g of must be dissolved in 0.504 L of a solution to make a 0.56 M solution.

Answer:
CH₄ and N₂O are not likely to be biologically important greenhouse gases for tree growth
Explanation:
From the discussion of the experiment testing the given hypothesis in the question, all the gases tested, CO2, N2O and CH4 are all green house gases. The aim of the experiment was to ascertain the impact of the selected greenhouse gases on plant biomass. It was observed that CO2 does lead to increase in plant biomass while N2O and CH4 did not.
A proper deduction from the experiment will be 'CH₄ and N₂O are not likely to be biologically important greenhouse gases for tree growth'.
Answer:
It has two sigma bonds ( the single bonds between each H and C) plus one pi bond and one sigma bond that consitute the double bond between C and O. It contains three covalent bonds, one . Hydrogen Bond Donor Count: 0: Computed by Cactvs 3.4.
