The ____________ (size/color) of crystals formed depends on the speed of evaporation.

serg [7]

The right answer is the size.

Crystallization is the operation that consists, of a solution (solvent + solute) or a molten solid, to form a crystallized solid. The solute crystallizes in general in a predefined geometrical form (cubic, face-centered cubic, etc.), including or not solvent molecules (eg pure NA2SO4 or [Na2SO4, 10H2O]). The form or chemical formula of the crystals may depend on the crystallization temperature.

There are two ways of crystallization: The dry way and the wet way (in solution)

In crystallization in solution: the solute is initially in the liquid phase in a solvent. It is crystallized (solidification ordered according to a regular structure) within the solution either by solvent evaporation, or by cooling the solution, or both.

Answer: Oxygen

Explanation:I hope it helps . i have breifly explained it .

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

Grade7 science how populaation changes quiz biotic and abiotic

Greeley [361]

Answer:

Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.

Support irnas claim,using two pieces of evidence from the scientists experiment,figures 1 through 7, and both tables. Explain wh

Ulleksa [173]

Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical) or the order of nucleotides (biological evidence).

<h3>What is scientific evidence?</h3>

Scientific evidence refers to the observations that can be used to support (or reject) a working hypothesis.

Scientific evidence is variable depending on the field but it is always collected by observational or experimental procedures.

In conclusion, Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical evidence) or the order of nucleotides (biological evidence).
