Answer:

HO2; Hydroperoxyl

Explanation:

Since there are two oxygen molecules, and one hydrogen molecule, it can be classified as a hydroperoxyl molecule.

It is an inorganic compound with the following characteristics

  • Covalent compound (O,H are nonmetals)
  • Valence of O (O must form an octet): 6
  • Valence of H: 1
  • Total valence electrons: 13
  • Molar mass: 33.01 g/mol

5) Determine the mass if lithium hydroxide that is produced when 12.87 g of lithium
netineya [11]

Answer: 26.54 grams

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of lithium nitride}=\frac{12.87g}{34.83g/mol}=0.369moles

Li_3N+3H_2O\rightarrow 3LiOH+NH_3  

Li_3N is the limiting reagent as it limits the formation of product and H_2O is the excess reagent

According to stoichiometry :

As 1 moles of Li_3N give = 3 moles of LiOH

Thus 0.369 moles of O_2 give =\frac{3}{1}\times 0.369=1.108moles  of LiOH

Mass of LiOH=moles\times {\text {Molar mass}}=1.108moles\times 23.95g/mol=26.54g

Thus  26.54 g of LiOH will be produced from the given mass.

10 moles of carbon dioxide has a mass of 440 g. What is the relative formula mass of carbon dioxide?
Ksenya-84 [330]

Answer: 44g

Explanation: The formular for finding Moles is ;

Moles =  Mass / Molar Mass or Formular Mass.

Base on this question; Moles = 10, Mass = 440g, and Formular Mass = ?

Making 'Formular Mass', subject of the formular; we thus have;

Formular mass = Mass / Moles = 440/ 10 = 44g

When multiplying numbers in scientific notation what do you do with exponents?
Basile [38]

Answer:

Subtract them.

Explanation:

''''"Since all number in scientific notation have base 10, we can always multiply them and divide them. To multiply two numbers in scientific notation, multiply their coefficients and add their exponents. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents."""""

I was actually learned about this in school just found an source.
