Which of the following statements concerning electrolytes and nonelectrolytes is/are true? 1. Some molecular substances are electrolytes. 2. All electrolytes are ionic substances. 3. Strong electrolytes partially ionize in solution.

Some molecular substance are electrolytes

Electrolytes are referred to as chemical compounds that can dissolve readily in water to form ions. The ions produced can conduct electricity through the solution.

Nonelectrolytes on the others end are chemical compounds that do not conduct electricity when dissolved in water. This is because they do not form ions when dissolved in water.

1. Some molecular substances are electrolytes

Explanation:

Electrolytes are electrically conducting solutions when dissolved in water and are found in cells .

In this case , all molecular substances can’t be electrolytes

Not all electrolytes are ionic. They could be ionic or covalent.

A strong electrolyte is known for its complete ionization in water and not for anything partial.

electrical power

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
