In this exercise we have to use the knowledge of lunar eclipse to identify the alternatives that correspond to this effect, as follows:

A lunar eclipse happens when the Earth is between the Moon and the Sun, at times when they are aligned. Depending on the position of the Moon, it is total, partial or penumbral. Different stages of a lunar eclipse on a full moon night.

Now,  use the knowledge of solar eclipse to identify the alternatives that correspond to this effect, as follows:

Solar eclipse is an astronomical phenomenon that occurs when the Moon is positioned between the Earth and the Sun, hiding the light emitted by the star towards the planet.

Answer:

35.0g of ice at 0 degrees

Explanation:

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.

Answer:

480 mL

Explanation:

15L  of  0.38M of NH3(aq.) means that we require 15x0.38 moles of NH3.

this is to be provided by 15M x V.  

Where V is volume in Liters.

These are equal  

⇒15M x V = 15x 0.48  

Hence, Volume required V = 0.48L =480mL

Specific Heat Formula: q = mcΔT

Step 1: Define

[Given] m = 38.8 g

[Given] q = 181 J

[Given] ΔT = 36.0 °C - 25.0 °C = 11.0 °C

[Solve] c

Step 2: Solve for Specific Heat

Step 3: Check

Follow sig fig rules and round. We are given 3 sig figs.

0.424086 J/g °C ≈ 0.424 J/g °C

Answer:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.
