Which processes must happen for sand to eventually become metamorphic rock? In one to two sentences, name and briefly describe t
trapecia [35]

Answer:

Sand may be deposited as sediments that become sedimentary rocks after hardening, or lithifying. Extreme burial pressure, rising temperature at depth, and a lot of time, will transform just about any rock to become a metamorphic rock.

What is the molarity of a solution in which 7.1 g of sodium sulfate is dissolved in enough water to make 100. mL of solution?
Sidana [21]

Answer:

0.50 M

Explanation:

Given data

  • Mass of sodium sulfate (solute): 7.1 g
  • Volume of solution: 100 mL

Step 1: Calculate the moles of the solute

The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:

7.1g \times \frac{1mol}{142.02g} = 0.050mol

Step 2: Convert the volume of solution to liters

We will use the relation 1 L = 1000 mL.

100mL \times \frac{1L}{1000mL} =0.100L

Step 3: Calculate the molarity of the solution

M = \frac{moles\ of\ solute }{liters\ of\ solution} = \frac{0.050mol}{0.100L} =0.50 M

Select ALL answers that apply to the total energy of a wave:
Verdich [7]

Answer:

(A) The shorter the wavelength, the more total energy the wave contains.

(B) The longer the wavelength, the less total energy the wave contains.

Explanation:

The wavelength (λ), frequency (f) and energy (E) are interrelated. This relationship between them is represented in the following equations:

λ = v/f and E = hf

Where;

λ = wavelength (m)

f = frequency (Hz)

E = energy (Joules)

v and h represents speed of light and Planck's constants respectively.

Combining both equations, E = hc/λ

This equation shows that ENERGY (E) is directly proportional to the frequency (f) but inversely proportional to the wavelength (λ). This means that "the shorter the wavelength, the more total energy a wave contains" and vice versa.

However, the higher the frequency, the more the total energy the wave contains and vice versa.
