Burning wood to power engines and machines ushered in the Industrial Revolution in 1769.Coal became the major fuel in the early
Sloan [31]

Answer:

Natural gas combustion equation:

CH4 + O2 ==> CO2 + 2 H2O + HEAT

Octane or oil combustion equation:

2C8H18 + 25 O2 ===> 16CO2 + 18 H2O.

If these fuels were replaced by self-sustaining energy sources, the contamination of the environment would be less, since their combustion generates toxic compounds that damage the ozone layer, promoting the greenhouse effect, increasing the Earth's temperature and also promoting the increase in the passage of ultraviolet radiation.

Explanation:

The combustion reactions are exothermic, and irreversible, they can be complete and incomplete combustions.

They always consist of oxygen as a reagent and water and carbon dioxide as a product (complete), in the case of the incomplete the difference is that the products vary and there may be waste or chemical compounds that failed to burn.

COMPARE: Identify three ways that a biologist’s research is similar to an astronomer’s.
dalvyx [7]
  1. Biologist and astronomer both use tools that magnify  so they are able to view minute objects. Astronomers use telescopes while biologists use microscopes.
  2. They both require data science due to the enormous data they are collecting that needs to be analyzed. Astronomers are collecting data on millions of stars and galaxies. Biologists require data science to analyze the enormous genomic data from populations.
  3. Both fields involve making new  discoveries due to the enormity of the scale in their scopes. Biologists and astronomy attempt to find new planets and those that could harbor extra-terrestrial life while biology attempts to find new undiscovered species of organisms on earth.

A 100-w light bulb is about 16% efficient. how many joules of heat energy are siddipated by the bulb each second
pickupchik [31]

Answer:

84 Joules are wasted per second.

Explanation:

An efficiency of 16% means 84% is wasted as heat energy.  

Therefore;

For a 100W bulb;

Heat wasted = 84/100 × 100 W

                      = 84 W

Therefore;

84 W or 84 joules are wasted as heat per second
