Answer:

D) Gases usually weigh less than solids

Explanation:

Gases don't have weight and solids do which automatically makes gases lighter because they don't have a mass like a solid.

Crude oil was formed by hydrocarbons or distillate from decaying animal matter migrating to stratigraphic traps like folds in the sedimentary rocks like anticlines which are dome-shaped folds in the rocks. 

In North America, the First Nations used the pitchy tar sands near Fort McMurray to waterproof their canoes long ago before the white man arrived.

In Alberta, the first successful oil well to be drilled was in approximately 1947 called the Leduc well and then oil drilling blossomed from there. Crude oil would be refined to process this oil at that time and broken down into fractions.
Large scale expansion of the oil industry got impetus from the widespread use of automobiles and planes in the early part of the 20th century and then once discoveries like the Leduc well were made, then it became apparent that it was possible to figure out where the oil was and then it blossomed.
In 1907. Leo Baekeland invented bakelite from petroleum ie a polymer. 
Nylon and polyester were developed from petroleum in the 1930's and 1941 respectively.,
In 1865, Edward Roberts, an American discovered that by exploding a torpedo with explosive powder in it in an oil well it could increase the well yield by up to 1200% 
Peak oil is estimated to be very soon between 2010 and 2030 or most likely before 2020 so anytime soon and after that the reserves are expected to diminish. The world should be converting strongly to alternative energy sources the sooner the better especially to prevent the potential pollution of pipelines and oil tankersl

It takes 26.8 mL of a 0.0700 M NaOH standard solution to neutralize a 250 mL sample of lactic acid (C3H6O3). What mass of lactic
Butoxors [25]
There is 1 OH- in 1 molecule of NaOH. 
Also, there is 1 H+ in 1 molecule of lactic acid.

So the reaction is simple.
so just equate the moles
moles of OH- in NaOH = moles of H+ in lactic acid
26.8 x 0.07 = 250 x Mole of lactic
Moles of lactic = 0.0075

so mass = 0.0075 x 90.8 =  0.681 g

In the reaction n2 + 3h2 ---> 2nh3, how many grams of nh3 are produced if 25.0 g n2 reacts with excess h2? question 10 option
Lisa [10]
Molar mass of N2 = 28

Moles of N2 = 25 / 28 = 0.89

So, moles of NH3 produce = 2 x 0.89 = 1.78 

Note: H2 is in excess. so no need to care about it.

Molarity of 0.50 mol sugar in 270 mL of solution.
EastWind [94]
<h3>Answer:</h3>

1.85 M

<h3>Explanation:</h3>

<u>We are given;</u>

  • Number of moles as 0.50 mol
  • Volume of the solution is 270 ml

But, 1000 mL = 1 L

  • Thus, volume of the solution is 0.27 L

We are required to calculate the molarity of the solution;

  • Molarity refers to the concentration of a solution in moles per liter.
  • It is calculated by dividing number of moles with the volume.

Molarity = Moles ÷ Volume

In this case;

Molarity = 0.50 moles ÷ 0.27 L

             = 1.85 Mol/L or 1.85 M

Therefore, molarity of the solution is 1.85 M
