Answer:

To calculate the theoretical yield, determine the number of moles of each reactant, in this case the sole reactant ethanol. Convert the 100 g to moles; the molecular weight of ethanol is 46 g/mole, therefore: Since there is only one reactant, it is also the limiting reagent.

2. Describe How are the two forms of energy<br> carried by waves and matter related?
Kazeer [188]

Answer:

the energy of matter implies the motion of masses and the energy of the wave has no moving masses

The energy of the particles (matter) is the ability to do some work, therefore the energy can be of motion in the form of kinetic energy or in a configuration of the system called potential energy, the sum of these two energy is constant .

The wave is formed by a disturbance of the medium by matter, therefore for the formation of the wave matter supply energy, for example: in the form of movement, in the form of fluctuation of electric or magnetic field, etc.

The waves after being formed can move away from the matter that formed them, transporting the energy that alternately has kinetic and potential energy, but the total energy is constant.

Therefore the energy in matter is due to the movement of the same and the energy in the wave does not require the movement of matter, so it is a more efficient way of doing work.

In conclusion, the energy of matter implies the movement of masses and the energy of the wave has no moving masses.

What is the formula mass of the fictitious compound: AB2?
Rus_ich [418]
For a molecule AB2, 3.5g of A represents one molar fraction, and 8.00g B represents 2 molar fractions (or 4.0+4.0). Therefore, a direct ratio can be given as 3.5:4.0, or 1:1.14. This means a molecule AnBm will give a mass ratio for A:B of n:1.14xm

For a molecule AB, for every 1g of A, you will have 1.14g of B.

For a molecule AB2, for every 1g of A, you will have 2.28g of B.

For a molecule A2B3, for every 1g of A, you will have (1.14x3/2) 1.71g of B.

Polar solvents dissolve _____ solutes and non-polar solvents _____ solutes.
Nitella [24]

What takes pictures of clouds and storm systems from the exosphere
tamaranim1 [39]

The answer should be "Satellite." The satellite is placed in the exosphere which allows it to take pictures of the clouds from above, which is also how NASA gets most of it's pictures of the planet.

Hope this helps!
