Explanation:

Scientists debated about the nature of electromagnetic radiation for more than 200 years because they could not distinguish if the radiations were made up of waves or just particles. This debate was between 1600 to the early part of 1900s.

Some scientists believed that electromagnetic radiations were made up of purely waves.
Some were of the school of thought that the radiations consists of jsut particles.
The wave-particle theory by Albert Einstein provided solution to this debate.
He simply propounded that electromagnetic radiations are made up of both waves and particles.

Today, it is widely accepted and known that electromagnetic radiations consists of both waves and particles.

Calculate the percent yield if 52.9 g of ethanol reacts to produce 26.7 g of ether.

blagie [28]

Answer:

The % yield is 62.7 %

Explanation:

Step 1: the balanced equation

2CH3CH2OH(l) → CH3CH2OCH2CH3(l) + H2O(l)

Step 2: Data given

mass of ethanol = 52.9 grams

molar mass of ethanol = 46.07 g/mol

mass of ether = 26.7 grams

Molar mass of ether = 74.12 g/mol

Step 3: Calculate moles of ethanol

Number of moles = Mass / molar mass

Moles of ethanol = 52.9 grams / 46.07 g/mol

Moles of ethanol = 1.15 moles

Step 4: Calculate moles of ether

For 2 moles of ethanol consumed, we have 1 mole of ether produced

For 1.15 moles of ethanol consumed, we have 1.15/2 = 0.575 moles of ether produced

Step 5: Calculate mass of ether

Mass = moles * Molar mass

Mass ether = 0.575 moles * 74.12 g/mol = 42.62 grams = theoretical yield

Step 6: Calculate % yield

% yield = (26.7 / 42.62) * 100 = 62.7%

The % yield is 62.7 %

Currently proven global reserves are expected to be largely exhausted within the next 50 years. Uranium-238 A Coal B Natural gas

Komok [63]

Answer:

Option (D)

Explanation:

Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.

It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.

It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.

Thus, the correct answer is option (D).
