To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom.
A calorimeter experiment is a set-up that provides insulation so that no heat escapes to the surroundings and all energy can be accounted for. It can be done at either constant volume or constant pressure. So, the answer to this is knowing the mass of water, the specific heat which is an empirical data, and the change in temperature which can be measured using a thermometer. This experiment could measure the mass of an unknown substance added or the specific heat of the substance or the calorimeter. <em>The answer is D.</em>
Answer:
Do you have a picture
or can you state the reaction
Answer: The purpose of a hypothesis is to find the answer to a question.
Explanation:
A hypothesis is a statement which is written as a source of prediction which is based upon the assumption of the cause of a natural event or process. The purpose of the hypothesis is basically to find the relevant answers to the scientific question. It is based upon few evidences and the entire statement of the hypothesis is tested using experimental procedures.
If it’s (5.93 x 10^3) x (2.3 x 10^-2)
The answe is:
= 13.63 x 10^1
Round to the nearest two significant figures.
= 14 x 10^1
Making sure it’s in proper scientific notation.
[= 1.4 x 10^2]
