When a block of ice is placed in a frying pan, it is first in a solid state, meaning that the particles are moving slowly and are tightly compacted together as well as vibrating. As the the temperature of the pan increases, the state of matter will go from a solid to a liquid, which will cause the thermal energy in the ice cube to increase and the particles will go from a vibrating state, to sliding state. By this time the ice will now be water. As the temperature of the pan continues to increase, the water will eventually become water vapor and turn into a gas because as the particles are heated, they will move faster causing them to expand.
Historically, the left hemisphere was seen as the dominant hemisphere of the brain.
Hope I helped! :)
The question is incomplete, here is the complete question:
A student sets up the following equation to convert a measurement. (The stands for a number the student is going to calculate.) Fill in the missing part of this equation.
<u>Answer:</u> The measurement after converting is
<u>Explanation:</u>
We are given:
A quantity having value
To convert this into , we need to use the conversion factors:
1 kPa = 1000 Pa
Converting the quantity into , we get:
Hence, the measurement after converting is
Answer:
1.092 moles of Mg
Explanation:
Avogadro's number is a constant that define the number of particles (Such as atoms, molecules, electrons, ions) that you have in 1 mole. That means in 1 mole you have 6.022x10²³ of the particle in question.
If you have 6.578x10²³ atoms of Mg -and 1 mole of Mg contains 6.022x10²³ atoms of Mg-:
6.578x10²³ atoms of Mg × (1 mole Mg / 6.022x10²³ atoms of Mg) =
<h3>1.092 moles of Mg</h3>
