DENIUS [597]3 years ago
8 0

Answer:

density =mass/volume

Explanation:

volume is in mL

convert it into cm³

0.000025cm³

density=20/0.000025

20×10 power 6/25

0.8×10 power 6 g/cm³

or

0.8 g/ml

Answer: Density = 0.8 g/mL

Explanation: Density is the ratio between mass per unit volume

D= m/V

= 20 g / 25 mL

= 0.8 g/ mL

The process of ____ occurs when magma, lava, or a solute in a solution becomes a solid and the internal components will arrange
satela [25.4K]

Answer:

D. Crystallization

Explanation:

Let's clarify the irrelevant terms first.

  1. unification: This term has nothing to do with chemistry at all
  2. lithification: When the problem mentions magma and lava, you might think that this term is related to the process here. However, 'lithification' <em>do </em>have a precise meaning in geology. It refers to the process where sediments collapses into one single rock under pressure, which has nothing to do with the process mentioned here.

Now, for 2 terms that might confuse you: 'solidification' and 'crystallization' these also has precise scientific definition

Solidification is defined the process where substances in <em>liquid</em> phase changes its phase to <em>solid</em>. On first glance, this answer might seems correct, and yes, it is correct for this question. But not the <em>most</em> correct.

The keyword here is  

 'the internal components will arrange its self in an  organized pattern.'

Crystallization is a special case of Solidification where the atoms or molecules of liquid solidify by spontaneously arrange themselves in periodic, ordered, and organized pattern. It might or might not happen during solidification depending on cooling rate, viscosity of liquid, and other factors.

So, Crystallization is the most correct answer here.

During photosynthesis, ________.
ludmilkaskok [199]

Answer:

d. there is a net consumption of water and carbon dioxide

Explanation:

Photosynthesis, is the process whereby light energy is transform into chemical energy by

green plants and other photosynthesis capable organisms . In the process of photosynthesis, light energy is captured by green plants which it uses to convert carbon dioxide water, and minerals into energy-rich organic compounds and oxygen is evolved as a byproduct.

It is a chemical reaction taking place inside a plant, resulting in the production of food for the survival of the plant.

Photosynthesis takes place in the leaves of a plant in the presence of sunlight and.
