Answer:

[tex]0.16\; \rm mol[/tex].

Explanation:

[tex]\rm H_2[/tex] and [tex]\rm N_2[/tex] react to produce [tex]\rm NH_3[/tex] through the following reaction:

[tex]\rm 2\; N_2 + 3\; H_2 \to 2\; NH_3[/tex].

The ratio between the coefficients and [tex]\rm NH_3[/tex] and [tex]\rm H_2[/tex] is:

[tex]\displaystyle \frac{n({\rm NH_3})}{n({\rm H_2})} = \frac{2}{3}[/tex].

This coefficient ratio would be the ratio between the quantity of [tex]\rm NH_3[/tex] produced and the quantity of [tex]\rm H_2[/tex] consumed in this reaction only if [tex]\rm H_2\![/tex] is a limiting reactant.  

The other reactant in this reaction, [tex]\rm N_2[/tex], is in excess. Hence, [tex]\rm H_2[/tex] would be the limiting reactant. Hence, the coefficient ratio could be used to find the quantity of [tex]\rm NH_3[/tex] produced in this reaction.

[tex]\begin{aligned}n({\rm NH_3}) &= \frac{n({\rm NH_3})}{n({\rm H_2})} \cdot n({\rm H_2}) \\ &= \frac{2}{3} \times 0.24\; \rm mol \\ &= 0.16\; \rm mol \end{aligned}[/tex].

Explanation:

The mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.

Answer:

LiCl because the total negative charge on Cl is one.

Explanation:

Lithium has a charge of 1+ and Chlorine has a charge of 1-.

There are two types of chemical compound one is covalent compound and other is ionic compound. LiCl because the total negative charge on Cl is one. The correct option is option A.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Ionic compounds are hard, these have higher melting and boiling point than the covalent compounds. Li act as cation Li⁺ and Cl act as Cl⁻. These two combine to form LiCl. LiCl is an ionic compound.

Therefore, LiCl because the total negative charge on Cl is one. The correct option is option A.

From the chemical equation it is clear that, one mole or 16 g of methane gas gives 2 moles or 36 g of water. Then, 15 g gives 33.7 g of water. The actual yield is 23.8 g. Then the percent yield is 70.6%.

Percent yield of a reaction is the ratio of its actual yield to the theoretical yield multiplied by 100. The theoretical yield is calculated from the balanced chemical equation of the reaction.

molar mass of methane gas = 16 g/mol

molar mass of water = 18 g/mol

16 g of methane gives 2 moles or 36 g of water. Then 15 g of methane will gives:

(15×36)/16 = 33.7g

The actual yield of water = 23.8 g

then,

percent yield = 23.8 g/33.7 g × 100 = 70.6%.

Therefore, the percent yield of water is 70.6%.

Explanation:

The cell represents the basic unit of life and any living organism.

One example of specialized cells in the body are the sex cells.

The sex cells are primarily concerned with reproduction and perpetuation of life. The cells undergo meiosis to produce haploid gametes. Male and female gametes then fuse together during fertilization to give rise to diploid zygotes which eventually give rise to new organisms.

Answer: 0.245 m/s

Explanation:

So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s

Explanation:

Since methane gas is at 1 atm and 273 K, it is at standard temperature and pressure(STP).

One mole of every gas occupies 22.4 dm^3 at STP, and vice versa. So,

22.4 dm^3 at STP of CH4=1 mol=12+4(1)=16 g

0.462 L(0.462 dm^3) at STP of CH4

=(16 g×0.462 dm^3)/22.4 dm^3

=0.33 g

Explanation:

Infrared spectroscopy is concerned with transitions between vibrational energy levels. Each infrared active vibration leads to a change in dipole moment.

A ketone compound contains the -C=O group whose signal normally occurs at about 1710 cm-1.

A conjugated ketone is one in which the -C=O group is attached to the -C=C  group. This leads to delocalization and reduces the electron density of the C=O  double bond, which weakens this bond hence lowering the stretching frequency of the  -C=O bond from  1710 to about 1680cm-1.

Answer:

The final temperature of the mixture is 71.43 ⁰C

Explanation:

Given;

mass of ice, m₀ = 50 g

initial temperature of the ice, t₀ = 0 ⁰C

mass of water, m₁ = 500 g

initial temperature of water, t₁ = 75 ⁰C

specific heat capacity of ice, C₀ = 2.093 J/g⁰C

specific heat capacity of water, C₁ = 4.186 J/g⁰C

Let the final temperature of the mixture = T

The heat lost by the water = The heat gained by the ice

m₁c₁ (75 - T) = m₀c₀ (T - 0)

500 x 4.186 x (75 - T) = 50 x 2.093 x T

156975 - 2093T = 104.65T

156975  = 104.65T   +   2093T

156975  = 2197.65T

T = 156975 / 2197.65

T = 71.43 ⁰C

Therefore, the final temperature of the mixture is 71.43 ⁰C
