Explanation:

Osmosis is the movement of water molecules, across a semipermeable membrane, from a hypotonic solution to a hypertonic solution

Osmosis is critical in the maintenance of the right amount of water in the cells an organism. Water is a universal solvent and is especially important for biochemical activities of a cell. Osmosis maintains the right water homeostasis in cells.

Osmosis is useful in the absorption of water by the roots of the plants and the maintenance of transpirational pull that ensures herbecious plants remain upright.

Osmosis enables the opening and closing of plant stomata hence regulating the loss of water by the plants.

Which type of chemical reaction occurs in Ca + Cl2 mc009-1.jpg CaCl2?

gregori [183]

Answer : The correct option is, (a) Synthesis

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

$X+Y\rightarrow XY$

Combustion reaction : A chemical reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.

It is represented as,

$CH_4+2O_2\rightarrow CO_2+2H_2O$

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

$XY+AB\rightarrow XB+AY$

(X and A are the cations, Y and B are the anions)

The given reaction is, $Ca+Cl_2\rightarrow CaCl_2$

In this reaction, calcium combine with the chloride to form calcium chloride as a product.

Hence, the given type of reaction is a synthesis reaction.

Answer:

i. Molar mass of glucose = 180 g/mol

ii. Amount of glucose = 0.5 mole

Explanation:

<em>The volume of the glucose solution to be prepared</em> = 500 $cm^3$

<em>Molarity of the glucose solution to be prepared</em> = 1 M

i. Molar mass of glucose ( $C_1_2H_6O_6$ ) = (6 × 12) + (12 × 1) + (6 × 16) = 180 g/mol

ii.<em> mole = molarity x volume</em>. Hence;

amount (in moles) of the glucose solution to be prepared

= 1 x 500/1000 = 0.5 mole

3 NO2(g) + H2O(ℓ) −→

gulaghasi [49]

The balanced equation for the above reaction is as follows;
3NO₂ + H₂O --> 2HNO₃ + NO
stoichiometry of NO₂ to NO is 3:1
molar volume is where 1 mol of any gas occupies a volume of 22.4 L
volume of gas is directly proportional to number of moles of gas.
therefore stoichiometry can be applied for volume as well.
volume ratio of NO₂ to NO is 3:1
volume of NO₂ reacted - 854 L
therefore volume of NO formed - 854 L /3 = 285 L
volume of NO formed - 285 L
