Answer:

Explanation:

Modern Agriculture - The agricultural practices with modern technique like Fertilizers, Innovative hybrid seed, and utilization of machine call modern Agriculture.

Advantages -

Feeding to the population without scarcity of food grains.

Optimum Utilization of land (Crop intensity more then 300%)

Increased production of food grain.

Global Market - even our mangoes available at US and we are getting California apple too.

Due to factories and Machine use this industry is growing to and empowering good employment.

I hope this helps you :)

An unknown compound has the following chemical formula:

Softa [21]

Answer:

Formula of the compound = $P_2O_5$

Explanation:

Given,

No. of mole of O = 8.20 mol

No. of mole of P = 3.30 mol

Chemical formula = $P_2O_x$

Ratio of P and O = $\frac{2}{x}$

$\frac{2}{x} =\frac{3.3}{8.20} \\x \times 3.3 = 8.20 \times 2\\x = \frac{8.20 \times 2}{3.3} \\x=4.9969\\ = 5$

formula of the compound = $P_2O_5$

An electrochemical cell is constructed using electrodes with the following half-cell reactions.

marshall27 [118]

Answer:

E cell = +1.95 V

Explanation:

At Anode : Oxidation reaction takes place

At Cathode : Reduction reaction takes place

The reaction with lower value of reduction potential will undergo Oxidation

$Mn^{2+}(aq)+2e^{-}\rightarrow Mn(s)$ E = -1.18 V

This equation undergo oxidation reaction and become:

Anode(Oxidation-Half) :

$Mn(s)\rightarrow Mn^{2+}(aq)+2e^{-}$ E = +1.18 V

Cathode(Reduction-Half) :

$Fe^{3+}(aq)+e^{-}\rightarrow Fe^{2+}$ E =+0.77 V

To balance the reaction multiply reduction-Half with 2.We get :

$Fe^{3+} +2Mn(s)+\rightarrow Fe^{2+} + 2Mn^{2+}$

Note that E is intensive property , do not multiply E of oxidation-half with 2

Ecell = 0.77 -(-1.18)

E = +1.95 V

Benjamin Franklin invented the lightning rod as a way to prevent lightning from causing damage to property or people. Use this s

Lilit [14]

Answer:

By 1750, in addition to wanting to prove that lightning was electricity, Franklin began to think about protecting people, buildings, and other structures from lightning. This grew into his idea for the lightning rod. Franklin described an iron rod about 8 or 10 feet long that was sharpened to a point at the end.
