Yea but its not used very often
Answer:
0.013 moles Cl
Explanation:
Grams --> Moles Divide by Molar Mass
Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.
Set Up: (0.456 g Cl) (1 Cl / 35.5 g)
0.456 g * 1 = 0.456
0.456 / 35.5 = 0.01284507
Round to 0.013
Since you have not included the figures with the diagrams to select the right answer, I am going to explain the main differences that lead you to differentiate electrochemical cells.
There are four important terms needed to identify the electrochemical cells: electrolysis, electrochemical cells, electrolitc cells and voltaic cells.
1) Electrochemical cell: is a device that uses a chemical reaction (redox reaction) to produce electricity or that uses electricity to product a chemical reaction.
2) Electrolysis: is the production of a chemical reaction using electricity.
3) Electroltic cell: is one of the two types of electrochemical cell. It is that in which electricity is used to produce the chemical reaction, i.e. where electrolysis happens. For example, the decomposition of sodium chloride brines is done in an electrolitic cell.
4) Galvanic cell: is the other type of electrochemical cell. It is that in which chemical reactions (redox reactions) produce electricity. The battery of the car is an example of a galvanic cell.
Here you are asked to identify which diagram shows a voltaic cell.So, you need to lool at:
- a redox reaction is happening
- this redox reaction is producing electricity (not that the electricity is producing the reaction)
Remember that a redox reaction is where some atoms are being reduced (gaining electros) and others are being oxidized (losing electrons).
Tha information will let you to choose the righ diagram.
An inefficient appliance costs less to operate than an efficient one, because it takes more energy to do the same job is "False".
<u>Answer:</u> Option B
<u>Explanation:</u>
Energy efficiency is about utilizing less energy consuming appliances than inefficient appliance which consume more energy to do the similar job and support for avoiding high energy bills and unnecessary pollution in the process.
The choice for energy efficiency is "ENERGY STAR LABEL" makes it known to consumers or businesses that a product, home or building is more energy efficient than others on the market.
ENERGY STAR and its partners have managed to save nearly 4 trillion kilowatt-hours of electricity from American families and businesses in 2017 and resulted into 3 billion metric tons of greenhouse gas reductions.
Answer:
8 amino acids
Explanation:
Amino acids are referred to as organic compounds containing carboxylic acid functional groups and amine. Amino acids contain different elements such as nitrogen, hydrogen, carbon and oxygen. Examples of amino acids are glycine, glutamic acid and alanine. In the given alignment, there are 8 amino acids between the sequence of human and monkey.
