  • A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
  • A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
  • Additionally, the chemical formula shows the number of each type of atom in a molecule.
  • In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.

HOW DOES ENERGY FROM THE<br> SUN ULTIMATELY CAUSE THE<br> BLADES ON THESE WIND<br> TURBINES TO MOVE?
Anarel [89]
Energy in wind comes from the sun. for example, when the Earth’s surface absorbs the suns energy, it turns to heat. wind is produced by uneven heating from the earths surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. The blades on the wind turbine move from the wind. i hope that made sense, if it didn’t i’m sorry, i hoped that hep though!

Consider a balloon with volume V. It contains n moles of gas and has an internal pressure of P. The temperature of the gas is T.
Stels [109]

Given that the gas inside the balloon is an ideal gas, then the ideal gas equation can be used to describe the system. I think the correct answer from the choices listed above is option B. If the balloon is heatedto a temperature of 15.5T while it is placed under a high pressure of 15.5P, then the volume of the balloon stays the same since the change in temperature corresponds to same degree of change with pressure.

N76 [4]

Answer:

d. O2 > CoQ > FAD > NAD+

Explanation:

O2 > CoQ > FAD > NAD+

Because the reason is O2 is the last electron acceptor in the chain for a reason. FAD is also introduced later in the ETC(Electron transfer chain) than NAD+ and generates less ATP.
