Solve for x.
pv=xrt
Flip the equation.
rtx=pv
Divide both sides by rt.
rtx.rt = pv/rt
x = pv / rt
Hey! In order to answer this question, we need to understand the difference between mass and density. Mass is the property of matter that measures its resistance to its acceleration, while density is the measure of mass per volume.
Mass is independent as it just focuses on how heavy an object is while density isn't. It can be represented by this equation.
Density = Mass/Volume
If the iron block has more mass per volume than the gold. Then you can consider that the iron has a higher density than gold. However, only if both have the same amount of volume. If there is less or more, then it can fluctuate.
Answer:
A) CaF 2 (Calcium Fluoride)
C KBr (Potassium Bromide)
D) Mgl 2 (Magnesium Iodide)
Explanation:
All the above are electrolytes, because of their ability to dissociate/ionize when dissolved. Strong electrolytes completely ionize when dissolved, and not neutral molecules are able to form in the solution. Electrolytes are substances that conduct electric currents as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals (cathode and anode) of an electric circuit, respectively.
The scientist that developed the equation of wave mechanics is <span>Erwin Schrodinger that combined the works of Bohr and de Broglie. The electron
was a three dimensional wave circling the nucleus in a whole number of wavelengths
allowing the waveform to repeat itself as a stable standing wave (it can absorb
energy form a nearby source which is oscillating at a proper frequency)
representing the energy levels of Bohr model. He also said that Broglie’s model
was correct about the matter waves and the electrons are located in the atomic
space according to standing wave frequencies.</span>
