Answer:
A fan is a common house appliance which is attached to the ceiling and uses an electric motor to rotate blades or paddles in a circular motion. Ceiling fans help cool a room by moving air which causes evaporative cooling. Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts.
where you have
Hours Used Per Day:5
Power Use (Watts): 75
Price (kWh): 0.01
then you have
Cost Per Hour=0.0075
Cost Per Day= 0.0375
Cost Per Month=1.14
Cost Per Year=13.69
kWh Per Day: 0.38
Water is amphoteric with both the acidic and basic characters.
<u>Explanation:</u>
As per the Bronsted Lowry theory of acids and bases,
Water has its own ability to either donate or accept hydrogen ions or protons.
- If it accepts a proton then it is termed as basic
- To accept a proton it should have a lone pair of electrons.
- If it donates a proton then it is termed as acidic
- If the water has the ability to accept as well as donating proton then it has both the acidic and basic characters and so it is termed as amphoteric in nature.
Answer:
11.3 g of are produced from 36.0 g of
Explanation:
1. The balanced chemical equation is the following:
2. Use the molar mass of the , the molar mass of the and the stoichiometry of the balanced chemical reaction to find how many grams of are produced:
Molar mass = 18
Molar mass = 17
Therefore 11.3 g of are produced from 36.0 g of
