Answer:

You are moving because the Earth and everything in our solar system is constantly moving. ... As the Earth rotates, it also moves, or revolves, around the Sun. The Earth's path around the Sun is called its orbit. It takes the Earth one year, or 365 1/4 days, to completely orbit the Sun.

Write the parts of the ear in their correct order of transfer of vibrations. to the brain.
dimaraw [331]

Answer:

The sound waves travel from the outer ear and in through the auditory canal, causing the eardrum, or tympanic membrane, to vibrate. This, in turn, causes the three small bones, known as the ossicles, or the hammer, the anvil and the stirrup, in the middle ear to move.

What volume of ethanol (density = 0.7893 g/cm3) should be added to 450. ml of water in order to have a solution that freezes at
AysviL [449]
According to this formula :
ΔTf= i Kf m
i is van't Hoff factor= 1
Kf = 1.86 
m the molality we need to assume it 
m= x moles of C2H5OH / Kg of mass 
∴ 15 = 1 * 1.86 * ( x moles of C2H5OH/ 0.45 kg)
∴X = 3.629 moles 
mass = no.of moles x molar mass of C2H5OH
          = 3.629 X 46 = 167 g 
∴the volume = mass / denisty
                      = 167 / 0.7893 = 211.57≈ 212 mL

Please use the below balanced equation to answer this question.    2H2(g)  +  O2(g)  ->   2H2O(l) How many grams of water wil
Blizzard [7]
At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L 
This rule is applied to O₂
22.4 L volume occupied by 1 mol
Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol
stoichiometry of O₂ to H₂O is 1:2
then the number of moles of water produced - 3.72 mol x 2= 7.44 mol
mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g
correct answer is D
