<h3>Answer:</h3>

Stomata

<h3>Explanation:</h3>

Photosynthesis refers to the process that takes place in green plants and some algae.
During the process, water and carbon dioxide are converted to nutrients or organic compounds using energy from sunlight.
The process takes place in the chloroplast on the leaves of green plants.
The water used during photosynthesis comes from the soil and then transported by xylem tissue to the leaves where the process takes place.
Carbon dioxide enters the leaves through the stomata which are the sites for gaseous exchange.
Sunlight is trapped by green pigments on the leaves known as chlorophyll.

Which of the following abilities is NOT a physical property of matter?

Morgarella [4.7K]

Answer:

Ability to react chemically with other substances is not a physical property.

Explanation:

The ability to dissolve in other substance can be both physical and chemical property.

It depend upon the type of solute, solvent and reaction between them.

For example, if NaCl is dissolved in water it gives sodium and chloride ions which are behaving different from the original compound. it will be chemical change but if water is evaporated it will give back sodium chloride and than it will be a physical change.

But if dissolved substances make the mixture not compound it will than a physical change, and solubility will consider a physical property.

Physical properties:

The properties which are not associated with change in chemical composition are called physical properties.

Example

Density, color, hardness, conductance, melting point, boiling points all are physical properties.

Chemical properties:

The properties which are associated with change in chemical composition are called chemical properties.

Example:

Toxicity, flammability, heat of combustion etc.

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

The reaction of Hydrogen and oxygen:

H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)

What volume of water is needed for 0.196 mol of CdCl2 to prepare a 3.91 M solution? L

Brilliant_brown [7]

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Explanation:

Data given:

moles of Cd $Cl_{2}$ = 0.196 Moles

Molarity of the solution = 3.91 M

Volume in litres =?

molarity is calculated by the formula:

molarity = $\frac{number of moles}{volume in litres}$

putting the values in the above formula and rearranging it for volume:

volume = $\frac{number of moles}{molarity}$

volume = $\frac{0.196}{3.91}$

volume = 0.050 litres

0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.

Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.
