What volume of O2 at NTP is generated from 7.84 g of
FeSO, (NH4)2SO4.6H2O?


Answers

Answer:1.12 g

Explanation:Molar mass of compound ​FeSO4(NH4)2SO4.6H2O = 392.14 g mol-1

Number of moles of compound in 7.84g sample = 7.84 g/ 392.14 g mol-1

                                                                       = 0.02 mole

1 mole of sample contain 1 mole of Fe

So, 0.02 mole of sample would contain 0.02 moles of Fe.

Mass of Fe equivalent to 0.02 mole = 0.02 mol x molar mass of Fe

                                                    = 0.02 mol x 55.84 g mol-1

                                                   = 1.12 g

C. Solar power is a renewable energy source.
O
D. Solar power produces no carbon dioxide.

Answers

Answer: D.Solar power produces no carbon dioxide

Explanation:

Solar power produces no carbon dioxide. The solar panel's carbon footprint is roughly 20 times less than the carbon output of coal-powered electricity sources. Hence, option D is correct.

What is a solar power plant?

A solar power plant uses sunlight to get energy. As the sunlight is ample and renewable, one can use it to power up the home and business premises.

Biomass energy is an energy source that comes from plant materials such as wood, corn, sugarcane, and grasses, etc.

However, it needs less capital investment than setting up a solar power plant.

Solar Energy: The major advantage of solar is that the source of energy (sun) is free.

Hence, option D is correct.

how many grams of cacl2 can be produced from 50.0 grams of hcl

Answers

Answer:

76.0 g

Explanation:

Step 1: Write the balanced equation

2 HCl + Ca(OH)₂ ⇒ CaCl₂ + 2 H₂O

Step 2: Calculate the moles corresponding to 50.0 g of HCl

The molar mass of HCl is 36.46 g/mol.

50.0 g × 1 mol/36.46 g = 1.37 mol

Step 3: Calculate the number of moles of CaCl₂ produced from 1.37 moles of HCl

The molar ratio of HCl to CaCl₂ is 2:1. The moles of CaCl₂ produced are 1/2 × 1.37 mol = 0.685 mol.

Step 4: Calculate the mass corresponding to 0.685 moles of CaCl₂

The molar mass of CaCl₂ is 110.98 g/mol.

0.685 mol × 110.98 g/mol = 76.0 g

How many molecular orbitals are present in the valence band of a sodium crystal with a mass of 4.14 g

Answers

Answer:

Explanation:

Given that:

The mass of sodium crystal = 4.14 g

As a result, the number of atoms in the sodium crystal is:

[tex]=4.14 \g \times \dfrac{ 1 \ mol}{23.0 \ g }\times \dfrac{6.023 \times 10^{23} \ atoms}{1 \ mol}[/tex]

= 1.084 × 10²³ atoms

In the valence orbital of the sodium atom, there is just one electron.

As a result, the number of molecular orbitals produced by these atoms is= 1.084 × 10²³ molecular orbital

Because valence bands are created from occupied molecular orbitals, the number of valence bands created from the aforementioned molecular orbitals is:

[tex]= \dfrac{ 1.084 \times 10^{23}}{2}[/tex]

= 5.420 × 10²² orbitals.

If 2.45 g of iron are placed in 1,5 L of 0.25M HCl, how many grams of FeCl2 are obtained? Identify the limiting and excess reactants in this single replacement reaction. Fe + 2HCl = FeCl2 + H2

Answers

Answer:

5.56g of FeCl2 can be produced

Explanation:

To solve this question we must find the moles of each reactant. With the moles and the chemical equation we can find limiting reactant. With limiting reactant we can find the moles of FeCl2 and its mass as follows:

Moles HCl:

1.5L * (0.25mol / L) = 0.375 moles HCl

Moles Fe -Molar mass: 55.845g/mol-

2.45g * (1mol / 55.845g) = 0.0439 moles Fe

For a complete reaction of 0.375 moles HCl are needed:

0.375 moles HCl * (1mol Fe / 2mol HCl) = 0.1875 moles Fe

As there are just 0.0439 moles Fe, Fe is limiting reactant

1mol of Fe produce 1 mole of FeCl2, 0.0439 moles Fe produce 0.0439 moles of FeCl2. The mass is:

Mass FeCl2 -Molar mass: 126.751g/mol:

0.0439 moles Fe * (126.751g / mol) =

5.56g of FeCl2 can be produced

Calculate the mass of oxygen in 30 g of CH NH COOH?​

Answers

Molar mass of CH2NH2COOH - 75

Given mass of CH2NH2COOH - 30

Moles of CH2NH2COOH = Given mass/ Molar mass

moles of CH2NH2COOH = 30/75 = 0.4 mol

One mole of CH2NH2COOH contains 32 gram of oxygen

0.4 mole of CH2NH2COOH will contain = 0.4 × 32= 12.8 g of oxygen

Answer- the mass of oxygen in 30 g of CH2NH2COOH is 12.8 gram!

The mass of oxygen in 30 g of CH₂NH₂COOH is 12.8 g.

We'll begin by calculating the mass of 1 mole of CH₂NH₂COOH and the mass of oxygen in the compound.

1 mole of CH₂NH₂COOH = 12 + (2×1) + 14 + (2×1) + 12 + 16 + 16 + 1 = 75 g

Mass of oxygen in CH₂NH₂COOH = 16 + 16 = 32 g

Thus,

75 g of CH₂NH₂COOH contains 32 g of Oxygen.

With the above information, we can obtain the mass of oxygen in 30 g of CH₂NH₂COOH. This can be obtained as follow:

75 g of CH₂NH₂COOH contains 32 g of Oxygen.

Therefore,

30 g of CH₂NH₂COOH will contain = (30 × 32) / 75 = 12.8 g of Oxygen.

Thus, 12.8 g of Oxygen is present in 30 g of CH₂NH₂COOH

An archaeologist finds 14C in a sample of material to be decaying at 20 Geiger Counter clicks per second. A modern equivalent sample of the same material decays at 160 clicks per second. The half-life of 14C is 5,730 years. How old is the sample

Answers

Answer:

17188 years

Explanation:

Recall the formula;

0.693/t1/2 = 2.303/t log(No/N)

t1/2 = half life of 14C

No = initial activity of 14C

N = activity of 14C at time t

t = age of the sample

Substituting values

0.693/5730= 2.303/t log(160/ 20)

1.21 * 10^-4= 2.0798/t

t = 2.0798/1.21 * 10^-4

t = 17188 years

What is the entropy change in the environment when 5.0 MJ of energy is transferred thermally from a reservoir at 1000 K to one at 500 K

Answers

Answer:

The entropy change in the environment is 3.62x10²⁶.

Explanation:

The entropy change can be calculated using the following equation:

[tex]\Delta S = \frac{Q}{k_{B}}(\frac{1}{T_{f}} - \frac{1}{T_{i}})[/tex]

Where:

Q: is the energy transferred = 5.0 MJ

[tex]k_{B}[/tex]: is the Boltzmann constant = 1.38x10⁻²³ J/K  

[tex]T_{i}[/tex]: is the initial temperature = 1000 K

[tex]T_{f}[/tex]: is the final temperature = 500 K

Hence, the entropy change is:

[tex] \Delta S = \frac{5.0 \cdot 10^{6} J}{1.38 \cdot 10^{-23} J/K}(\frac{1}{500 K} - \frac{1}{1000 K}) = 3.62 \cdot 10^{26} [/tex]                                    

Therefore, the entropy change in the environment is 3.62x10²⁶.

what is the minimum mass of ethylene glycol that must be dissolved in 14.5 kg of water to prevent the solution from freexing at -14.2

Answers

Answer:

The minimum mass of ethylene glycol = 6.641 Kg

Explanation:

[tex]\Delta T_f= T_f-T_f'\\T_f'=T_f-\Delta T_f[/tex]

Where T_f = freezing point of pure solvent water, 0°C

T_f'= Freezing point of solvent after mixture

K_f = Freezing point depression constant = 1.86 °C/m

Moecular weight of ethylene glycol = 60 g/mol

Weight of ethylene glycol = 14.5 Kg= 14.5×10^3 g

molality of ethylene glycol

[tex]m = \frac{weight}{mol.wt} \times\frac{1000}{V}[/tex]

Substitute the values to calculate m

[tex]m = \frac{w}{60} \times\frac{1000}{14.5\times1000}[/tex]

by formula

[tex]0-(-14.2) =1.86\frac{w}{60} \times\frac{1000}{14.5\times1000}[/tex]
