Answer:

Consuming electricity: Burning fossil fuels emits CO2, with coal releasing twice as much of the gas as petroleum. Worldwide, fossil fuels generate 85 percent of electricity. The number of coal-burning plants will increase as China and India continue to industrialize.

What types of mixtures are these? (Homogeneous Mixture Hetergeneous Mixture)
salantis [7]

Explanation: A <u>homogeneous mixture</u> is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout.

A<u> heterogeneous mixture</u> has components whose proportions vary throughout the sample. The components of a heterogeneous mixture are visible and not uniform throughout. A heterogeneous mixture is simply any mixture that is not uniform in composition.

a) Peanuts and almonds mixed  together in a bowl  : The components(Peanuts and almonds) are visible in a bowl and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

b) Bucket full of sand and gravel  : The components(sand and gravel) are visible in a bucket and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.

c) Cup of tea and sugar  : The components(tea and sugar) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

d) Food coloring dissolved in water : The components(Food coloring and water) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

What is the mass (in grams) of 9.93 Ă— 1024 molecules of methanol (CH3OH)?
WINSTONCH [101]

Answer is: mass of methanol is 528.32 grams.

N(CH₃OH) = 9.93·10²⁴; number of methanol molecules.

n(CH₃OH) = N(CH₃OH) ÷ Na (Avogadro constant).

n(CH₃OH) = 9.93·10²⁴ ÷ 6.022·10²³ 1/mol.

n(CH₃OH) = 16.49 mol; amount of substance.

m(CH₃OH) = n(CH₃OH) · M(CH₃OH).

m(CH₃OH) = 16.49 mol · 32.04 g/mol.

m(CH₃OH) = 528.32 g.

what is the molarity of a concentrated hbr solution if the solution is 27.7% hbr by mass and has a density of 1.24 g/ml
givi [52]
Answer: 
         M = No.of moles of solute / Volume of solution in litres
  HBr: H = 1 x 1 = 1       Br = 1 x 80   
             Molar mass : 81 g / mol
  a.  n = 27.7% / 100 =0.277 g / (81 g / mol) = 0.0034 mol
       
       density = 1.24 g/ml ; D= m / v
               
  b.   65.32 ml x 1 L / 1000 mL = 0.065 L

    
   c. M= n / V
          = 0.0034 mol / 0.065 L
       M= 0.052 mol / L

The molarity of the concentrated HBr solution is 0.052 mol/L
