Answer:

94.74 moles of NO₂ are produced.

Explanation:

Given data:

Volume of oxygen gas = 3714 L

Temperature = 273 K

Pressure = 1 atm

Moles of NO₂ produced = ?

Solution:

Chemical equation:

4NH₃  + 7O₂   →      4NO₂ + 6H₂O

Number of moles of oxygen:

At STP one mole of any gas occupy 22.4 L volume. Thus, 3714 L gas contain,

3714 L× 1  mol / 22.4 L

165.8 mol

now we will compare the moles of oxygen and nitrogen dioxide.

                    O₂         :        NO₂

                     7           :          4

                   165.8      :        4/7×165.8 = 94.74 mol

Thus, 94.74 moles of NO₂ are produced.

Answer:

f = 1.09 × 10¹⁵ Hz

Explanation:

Given data:

Frequency of wave = ?

Wavelength of wave = 2.73 ×10⁻⁷ m

Solution:

Formula:

Speed of light = frequency × wavelength

speed of light = 3× 10⁸ m/s

by putting values,

3× 10⁸ m/s = f × 2.73 ×10⁻⁷ m

f = 3× 10⁸ m/s  / 2.73 ×10⁻⁷ m

f = 1.09 × 10¹⁵s⁻¹

s⁻¹ = Hz

f = 1.09 × 10¹⁵ Hz

Answer:

The Lewis dot diagram is supposed to have dots on each side. What's incorrect is that there isn't a dot on the bottom, only the left and right side and the top. What's correct about this is that there are 5 outer valence electrons, and they correctly put 5 dots, even though they're in the wrong place.

Explanation:

The given Lewis dot diagram of nitrogen is correct for the number of valence electrons for nitrogen. However, they are not correctly placed because two of them are lone pairs and only these two are shown as paired. Remaining three electrons have to be represented as single electrons.

Lewis dot structure of an element represent its valence electrons shown  as dots around the atom. The lone pair of electrons are shown as paired dots and other electrons as single dots.

For compounds, a Lewis diagram shows the bonded and non bonded electrons between bonded atoms. Nitrogen is 7th element and it contains 7 electrons in which 5 are valence electrons.

Nitrogen contains one lone pair of electrons. They have to be shown as paired dots in the Lewis structure. In the given diagram there are two pairs of electrons which is incorrect. Three electrons have to be shown as single dots.

Answer:

310.53 g of Cu.

Explanation:

The balanced equation for the reaction is given below:

CuSO₄ + Zn —> ZnSO₄ + Cu

Next, we shall determine the mass of CuSO₄ that reacted and the mass Cu produced from the balanced equation. This can be obtained as follow:

Molar mass of CuSO₄ = 63.5 + 32 + (16×4)

= 63.5 + 32 + 64

= 159.5 g/mol

Mass of CuSO₄ from the balanced equation = 1 × 159.5 = 159.5 g

Molar mass of Cu = 63.5 g/mol

Mass of Cu from the balanced equation = 1 × 63.5 = 63.5 g

Summary:

From the balanced equation above,

159.5 g of CuSO₄ reacted to produce 63.5 g of Cu.

Finally, we shall determine the mass of Cu produced by the reaction of 780 g of CuSO₄. This can be obtained as follow:

From the balanced equation above,

159.5 g of CuSO₄ reacted to produce 63.5 g of Cu.

Therefore, 780 g of CuSO₄ will react to produce = (780 × 63.5)/159.5 = 310.53 g of Cu.

Thus, 310.53 g of Cu were obtained from the reaction.

Explanation:

Answer:

3 M

Explanation:

Molarity is calculated by dividing the moles of the solute by the liters of solution. In this problem, we are given that the mass of the solution is 353.4 g and that the mass of the solute (H2SO4) is 25% of this.

Thus, you get that the mass of the solute is 88.35 g.

Next, you must convert the mass of the solute into moles. You must use the periodic table to find the molar mass of the solute in order to do the conversion.

Thus, you get that the number of moles of solute is 0.90.

Molarity is then = 0.90 mol/.300 L = 3 M.

The molarity of a 300ml solution of mass 353.4 g which is 25%by mass H₂SO₄ is 2.94 molar.It is calculated from the number of moles of sulphuric acid.

Molarity is a term used to represent the concentration of a solution. Mathematically it is the ratio of the number of moles of solute to the volume of solution in liter.

The mass percent of substance is the ratio of mass of that substance to the total mass. Here, the total mass of the solution is 353.4 g and the solute acid is 25% by mass. Thus mass of the solute is :

353.4 × 25 /100 = 88.3 g.

The molar mass of sulphuric acid is 100 g/mol. Thus number of moles of solute is 88.3 g/100 g/mol = 0.88 moles.

The volume of the solution is 300 ml or 0.3 liter. Now, the molarity of the solution can be calculated as follows:

Molarity = no.of moles of solute/volume in L

              = 0.88 mol / 0.3 L

              = 2.94 mol/L.

Hence, the molarity of the solution is 2.94 molar.

Answer:

The carbon dioxide molecule is linear and centrosymmetric at equilibrium. The carbon–oxygen bond length is 116.3 pm, noticeably shorter than the bond length of a C–O single bond and even shorter than most other C–O multiply-bonded functional groups. Since it is centrosymmetric, the molecule has no electrical dipole.

Answer: Gravity is considered a universal force because it acts between any two masses anywhere in the universe.

Answer:

Gravity (from Latin gravitas 'weight'[1]), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light[2]—are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Answer:

V = 53.83 L

Explanation:

Given data:

Number of moles = 2.00 mol

Temperature = 45°C (45+273 = 318 K)

Pressure = 98.6 KPa (98.6/101 = 0.97 atm)

Volume of gas = ?

Solution:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

0.97 atm × V = 2.00 mol × 0.0821 atm.L/mol. K × 318 K

V = 52.22 atm.L/0.97 atm

V = 53.83 L

Answer:

The scientific method is a process that can be used to answer any questions . The process begins when a scientist makes an observation. Then, they do research to learn more about the topic and write a hypothesis. The scientist will make predictions and conduct an experiment, eventually coming to a conclusion. They will share their results with other scientists to help further discovery.

Explanation:

The Scientific method is process used to observe, predict and explain phenomena around us. It involves a series of steps listed as follows:

1. Making observations: the scientist must be a keen observer of events around him

2. Ask questions: the scientist asks questions based on the observations

3. Form a hypothesis and make predictions: the scientist puts forward a reasonable explanation for the observations known as hypothesis. Predictions are then made and tested upon.

4. Experimentation: experiments are conducted to test the hypothesis and the predictions made.

5. Analysis of data and conclusion: the result of the experiments are analysed and conclusion are then drawn.

6. Communication of results: the results obtained from the experiments are then shared with other scientists to aid further research and discoveries.

The amount of 10.5 g magnesium carbonate is needed to make 5.0g of magnesium oxide.

So, option D is correct.

Given that, Magnesium carbonate decomposes on heating to form magnesium oxide and carbon dioxide as

                  MgCO₃ → MgO + CO₂

Molar mass of MgCO₃ = 24 + 12 + 48 = 84 g/mole

Molar mass of  MgO = 24 + 16 = 40g/mole

40 gram MgO is produced  from 84 gram of MgCO₃

1 gram of MgO produced  from  [tex]\frac{84}{40}=2.1[/tex] gram of MgCO₃

Therefore, 5 gram of MgO produced  from [tex](5*2.1=10.5gram)[/tex] of MgCO₃

Thus, option D is correct.

Answer:

16 neutrons.

Explanation:

From the question given above, the following data were obtained:

Mass number = 30

Atomic number = 14

Neutron number =?

Next, we shall determine the number of protons present in the isotope. This can be obtained as follow:

The atomic number of an element is simply defined as the number of protons present in the atom of the element. Thus,

Atomic number = Proton number

Atomic number = 14

Therefore,

Proton number = 14

Finally, we shall determine the number of neutons present in the isotope as follow:

Mass number = 30

Proton number = 14

Neutron number =?

Mass number = Proton + Neutron

30 = 14 + Neutron

Collect like terms

Neutron = 30 – 14

Neutron = 16

Therefore, the isotope contains 16 neutrons.

Answer:

V₂ =  1.92 L

Explanation:

Given data:

Initial volume = 0.500 L

Initial pressure =2911 mmHg (2911/760 = 3.83 atm)

Initial temperature = 0 °C (0 +273 = 273 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

by putting values,

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 3.83 atm × 0.500 L × 273 K / 273 K × 1 atm

V₂ = 522.795 atm .L. K / 273 K.atm

V₂ =  1.92 L
