From the graph, check for their point of intersection and trace it down to the temperature axis.

The point of saturation is the point it gets to and from thence, the solution can no longer take in the salt anymore. From this point, it begins to form precipitate while the solution remains unchanged.

Thus bromine water will be decolorized by alkynes due to the presence of two pi bonds available for reaction!

Photosynthesis is the process of food-making in plants, it doesn't have any by-products that pose a threat to the environment. Infact, the plants use our waste product of respiration (Carbon dioxide) and uses it for the photosynthetic process and gives off oxygen as by-product.

The position of equilibrium will shift under the effects of changes in temperature, pressure and concentration.

Heat energy near the ice gets absorbed into the ice. The energy breaks the bonds of the ice, causing it to melt into liquid water. On other words, when ice melts, the energy gets absorbed into the water.

Vapour is the equilibrium state between the gases and liquid, and it can bounce back to its original form, liquid with constant temperature and pressure exerted on it.

Using the formula, \(\frac{C_{A}V_{A}}{C_{B}V_{B}} = \frac{N_{A}}{N_{B}}\), we have \(\frac{0.1 \times V_{A}}{0.3 \times 25} = \frac{2}{1}\) \(V_{A} = \frac{0.3 \times 25 \times 2}{0.1 \times 1}\) \(V_{A} = 150cm^{3}\)

Copper is not active enough to replace hydrogen in an acid. Also, nitric acid is a strong oxidizing agent which quickly oxidises hygrogen to water.

The empirical formula is always in the ratio of the smallest positive integer, hence, \(N_{2}O_{4}\) has an empirical formula \(NO_{2}\).

Any pure substance will have a specific melting and boiling point. The presence of impurities alters the boiling point of benzene.

\(Cl_{2} + H_{2}O \to HCl + HOCl\) The two compounds in the product end are acidic and hence, their mixture is acidic. Hence, the pH is < 7

\(1 mole = 6.02 \times 10^{23} atoms\) \(0.2 moles = 6.02 \times 10^{23} \times 0.2\) atoms = \(1.204 \times 10^{23}\) \(\approxeq 1.2 \times 10^{23}\)

It is determined by the difference in the electron structures of the atoms. These primarily are: The number of outer electrons, i.e the number of valence shell electrons released during a metallic bond.

Reaction: \(2AgNO_{3} + Zn \to Zn(NO_{3})_{2} + 2Ag\) The oxidation number of Zn in the reactant is 0, and in the product is +2. Therefor, it is oxidized.
