Answer is D, they are compressible
Answer:
3.2 cm X 2.8 cm X 2.6 cm/ 1 cube - not exact
1 mL - exact
1 cm³ - exact
12 cubes/ 1 tray - exact
268.8 mL/tray - not exact
Explanation:
We can use the picture attached below to solve this problem. The first part is not exact because Sally is using a ruler to measure the cube which would have a margin of error, regardless of how small. The is exact, since that is the actual accurate exchange. Next, since there are 12 cubes in a single ice tray this measurement is also exact. Lastly, since Sally's initial measurement of the cubes is not exact, then the final calculated value will also not be exact.
The best example of immiscible liquids is
a polar liquid and a nonpolar liquid that do not dissolve into one another.
Explanation:
Immiscible averages that the fluids don't dissolve in each other – oil and water are an example. It is probable to swing up the juices and get them to mix but they soon separate. Departing immiscible liquids is done solely using a separating funnel.
Explanation:
It is known that relation between heat energy and temperature change is as follows.
Q =
where, q = heat energy
m = mass of the solution or solvent
= change in temperature
Hence, putting the given values into the above formula as follows.
Q =
=
= 34650 J
Now, calculate the energy of photons at wavelength 3.02 mm as follows.
E =
where, h = planks constant =
c = velocity of light = m/s
= wavelength = 3.02 mm = m (as 1 m = 1000 mm)
Therefore, putting the given values into the above formula as follows.
E =
=
= J
Now, the number of photons required of energy J/photon for the total energy of 34650 J as follows.
n =
=
= photons
or, = photons
Thus, we can conclude that the minimum number of photons present are .
Answer:
5.30x10²³g
Explanation:
A mole can be understood as an amount of something.
One mole of eggs are 6.022x10²³ eggs
One mole of atoms are 6.022x10²³ atoms
One mole of molecules are 6.022x10²³ molecules
And 1 mole of M&M are 6.022x10²³ M&M. As 1 M&M weighs 0.88g, 1 mole will weigh:
0.88g*6.022x10²³ =
<h3>5.30x10²³g</h3>
