Given the following balanced equation , if 5.00 moles of hydrogen gas and 5.00 miles
Answer:
Explanation:
The clock now has potential energy. When the alarm rings, the potential energy is converted into kinetic energy and sound energy.
Alarm clock runs due to the electrical energy. Due to the electric current, the electric motor rotates the blade. It means that the electrical energy is converted into mechanical energy.
The mechanical energy finally generates vibrations which cause sound.
Thus, energy transformation which takes place in alarm clock will follow the order-
Electrical to mechanical to sound.
Answer:
Let's assume that the erosion rate is "X/hour". The total volume of sand on a beach after 24 hours would be,
= total sand volume - (erosion rate per hour * 24)
= 1,278m - (X/hour * day)
Explanation:
Now assume that the erosion rate is 1 m per hour. Therefore, in 24 hours would be,
= 1,278m - (1/hour * 24)
= 1,278 - 24
= 1254 m.
The total number of protons and neutrons in an atom is called the mass number. You can find the mass numberfor any element. The mass number canbe found by rounding the average atomic mass to the nearest whole number.
as an example
6.25 is closer to 6 than 7 so it is 6
6. 50 is closer to 7 so it is 7
you have to look at the thenth digit. if the number is 4 or less you have to round it down
if the tenth digit is 5 or greather than you have to round it up.
Answer:
Components of crude oil can be separated through a process called <u><em>fractional distillation</em></u>.
Explanation:
Fractional distillation can be described as a method of distillation in which a liquid mixture is separated based on the different boiling points of the components present in the mixture. The components of crude oil have different boiling temperatures hence, they can be separated by the process of fractional distillation.
The fractionating column has high temperatures at the bottom so components with high temperatures are separated at the bottom. The upper columns have lower temperatures. Components with lower boiling temperatures get separated at the upper columns.
