Answer:

The percentage efficiency of the electrical element is approximately 82.186%

Explanation:

The given parameters are;

The thermal energy provided by the stove element, [tex]H_{supplied}[/tex] = 3.34 × 10³ J

The amount thermal energy gained by the kettle, [tex]H_{absorbed}[/tex]  = 5.95 × 10² J

The percentage efficiency of the electrical element in heating the kettle of water, η%, is given as follows;

[tex]\eta \% = \dfrac{H_{supplied} - H_{absorbed} }{H_{supplied}} \times 100[/tex]

Therefore, we get;

[tex]\eta \% = \dfrac{3.34 \times 10^3 - 5.95 \times 10^2}{3.34 \times 10^3} \times 100 = \dfrac{549}{668} \times 100 \approx 82.186 \%[/tex]

The percentage efficiency of the electrical element, η% ≈ 82.186%.

Answer:

Final pressure, P2 = 1088.89 atm

Explanation:

Given the following data;

To find the final pressure (P2), we would use the combined gas law.

Mathematically, the combined gas law is given by the formula;

[tex] \frac {PV}{T} = k [/tex]

[tex] \frac {P_{1}V_{1}}{T_{1}} = \frac {P_{2}V_{2}}{T_{2}} [/tex]

Substituting into the formula, we have;

[tex] \frac {1.19*715}{30} = \frac {P_{2}*1.12}{43} [/tex]

[tex] \frac {850.85}{30} = \frac {P_{2}*1.12}{43} [/tex]

[tex] 28.3617 = \frac {P_{2}*1.12}{43} [/tex]

Cross-multiplying, we have;

[tex] 28.3617 * 43 = 1.12P_{2} [/tex]

[tex] 1219.5531 = 1.12P_{2} [/tex]

[tex] P_{2} = \frac {1219.5531}{1.12} [/tex]

Final pressure, P2 = 1088.89 atm

Calculate the volume (in L) occupied by 3.40 g of NH3 at STP. (STP: 0 degree Celsius and 1 atmosphere of pressure).

Explanation:

To get the volume of ammonia gas at STP, calculate the number of moles of [tex]NH_3[/tex] in the given amount.

Number of moles of [tex]NH_3[/tex] gas is:

[tex]number of moles of NH_3 gas&=\frac{given mass of the gas}{its molecular mass} \\ &=\frac{3.40g}{17.0g/mol} \\&=0.2 mol.[/tex]

Since,

1 mol of any gas at STP occupies ------- 22.4 L of volume.

then,

0.2 mol of [tex]NH_3[/tex] occupies how much volume?

[tex]=>0.2 mol x \frac{22.4 L}{ 1.0 mol} \\=4.48 L[/tex]

Hence, the volume occupied by 3.40 g of ammonia at STP is --- 4.48 L.

(1) Seven electrons

1s² 2s²2p³

There are two electrons in the 2s subshell and three in the 2p subshell. The remaining two electrons are in the inner 1s subshell.

(2) 22 electrons

1s² 2s²2p⁶ 3s²3p⁶ 4s²3d²

There are two electrons in the 4s subshell and two in the 2p subshell. The remaining 18 electrons are in the inner subshells.

(3) 17 electrons

1s² 2s²2p⁶ 3s²3p⁵

There are two electrons in the 3s subshell and five in the 2p subshell. The remaining 10 electrons are in the inner subshells.

(4) n = 4, l = 2

(5) N=2 I=0 MI=0

(6) There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.

(7) n = 4 can hold up to 16 electrons

There are 4 sublevels; 42, 4p, 4d and 4f

4s (1 orbital), 4p (3 orbitals)

4d (5 orbitals), 4f (7 orbitals)

Maximum number of electrons in energy level: 16

s = 1 orbital

p = 3 orbitals

d = 5 orbitals

f = 7 orbitals

Add these up;

1 + 3 + 5 + 7 = 16

(8) 14 electrons If l = 3, the electrons are in an f subshell. The number of orbitals with a quantum number l is 2l + 1, so there are 2×3 + 1 = 7 f orbitals. Each orbital can hold two electrons, so the f subshell can hold 14 electrons.

Answer:

B. O2 is reduced when it accepts electrons and forms water.

Explanation:

During cellular respiration water is formed when oxygen receives electrons and picks up protons at the conclusion of the electron transport chain. The electron transport chain will stop functioning if there isn't enough oxygen to receive electrons (for example, because a person isn't breathing in enough oxygen), and ATP will no longer be created by chemiosmosis. Cells can't carry out the reactions they need to function if they don't even have enough ATP, and they may perish after a long period of time.

25 PRECENT

Explanation:

The question is: If 40 g of a compound C6H10O5 are dissolved in 500 g of water, determine the boiling point of this solution. (Water: boiling temperature 100 ° C and Kb = 0.52 ° C / m).

Answer: The boiling point of given solution is [tex]100.256^{o}C[/tex].

Explanation:

Given: Mass of solute = 40 g

Mass of solvent = 500 g (1 g = 0.001 kg) = 0.5 kg

[tex]K_{b} = 0.52^{o}C/m[/tex]

Molality is the moles of solute present in kg of solvent.

Moles is the mass of substance divided by its molar mass. Hence, moles of [tex]C_{6}H_{10}O_{5}[/tex] (molar mass = 162.141 g/mol) is calculated as follows.

[tex]Moles = \frac{mass}{molar mass}\\= \frac{40 g}{162.141 g/mol}\\= 0.246 mol[/tex]

Now, molality of the solution is calculated as follows.

[tex]Molality = \frac{molesof solute}{mass(in kg)}\\= \frac{0.246}{0.5 kg}\\= 0.492 m[/tex]

The boiling point is calculated as follows.

[tex]\Delta T_{b} = K_{b}m[/tex]

where,

m = molality

Substitute the values into above formula as follows.

[tex]\Delta T_{b} = K_{b}m\\= 0.52^{o}C/m \times 0.492 m\\= 0.256^{o}C[/tex]

As the boiling point of water is 100 degree Celsius. So, the boiling point of solution is as follows.

[tex](100 + 0.256)^{o}C\\= 100.256^{o}C[/tex]

Thus, we can conclude that the boiling point of given solution is [tex]100.256^{o}C[/tex].

Answer: Covalent bonding is when atoms of different elements  share electrons

Explanation: Taking Methane CH₄

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, sharing of electron is the only basis for the formation of covalent bond in methane.

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

Carbon has an electrical configuration of 2,4. Hydrogen only has one electron in its valence shell, whereas carbon contains four electrons. In order to create methane, carbon forms a covalent connection with four hydrogen atoms, sharing its four electrons with them.

Therefore, sharing of electron is the only basis for the formation of covalent bond in methane.

Explanation:

In Bohr's theory, electrons are found in specific regions in space called orbits. These orbits are also called energy levels. An electron may move from one energy level to another by absorbing or emitting energy.

In the wave mechanical model, electrons are not found in a particular region in space according to Heisenberg's uncertainty principle.

We rather define a certain region in space where there is a high probability of locating the electron. This region in space where there is a high probability of locating the electron is called an orbital.

Hence, in the Bohr's model of the atom,electrons can surely be found in orbits while in the wave mechanical model, the orbital is a probability function that describes a region in space where an electron may be found.

Answer:

For 1: 6.68 g of nitrogen dioxide will contain [tex]8.73\times 10^{22}[/tex] number of molecules

For 2: The given amount of nitrogen dioxide molecules has a mass of 41.31 g.

Explanation:

According to the mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex] ......(1)

We are given:

Mass of nitrogen dioxide = 6.68 g

Molar mass of nitrogen dioxide = 46 g/mol

Putting values in equation 1, we get:

[tex]\text{Moles of nitrogen dioxide}=\frac{6.68g}{46g/mol}=0.145mol[/tex]

Using above concept:

If 1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules

So, 0.145 moles of nitrogen dioxide will contain = [tex](0.145\times 6.022\times 10^{23})=8.73\times 10^{22}[/tex] number of molecules

Hence, 6.68 g of nitrogen dioxide will contain [tex]8.73\times 10^{22}[/tex] number of molecules

We are given:

Molecules of nitrogen dioxide = [tex]5.41\times 10^{22}[/tex] molecules

Using the above concept:

If [tex]6.022\times 10^{23}[/tex] number of molecules are present in 1 mole of a compound

So, [tex]5.41\times 10^{22}[/tex] number of molecules will be present in = [tex]\frac{1mol}{6.022\times 10^{23}}\times 5.41\times 10^{22}=0.898[/tex] moles of nitrogen dioxide

We know, molar mass of nitrogen dioxide = 46 g/mol

Using equation 1:

[tex]0.898mol=\frac{\text{Mass of nitrogen dioxide}}{46g/mol}\\\\\text{Mass of nitrogen dioxide}=0.898mol\times 46g/mol=41.31g[/tex]

Hence, the given amount of nitrogen dioxide molecules has a mass of 41.31 g.
