For neon, determine the moles and mass contained in a 29.9−L volume at a pressure of 481.1 torr at a temperature of 300.0 K.

Answers

Answer:

.7689 mol

15.516 g

Explanation:

Use the Ideal Gas Law, PV = nRT.

Make sure to use the correct ideal gas constant R. You can either put R in torr, or you can change the pressure to atm. I've just used the torr ideal gas constant.

481.1 torr * 29.9 L = n 62.364 LTorr/molK * 300 K

14384.89 = 18709.2n

n = .7689 mol

The molar mass of neon (remember that neon gas = Ne, it's not diatomic) is 20.18 g/mol from the periodic table.

.7689 mol * 20.18 g/mol = 15.516 g

What might happen to global atmospheric carbon levels if the polar ice caps were to melt?

Answers

If the Arctic became completely ice-free and phytoplankton productivity levels were maintained, Arrigo and his colleagues calculated that the new carbon sink could in theory absorb an extra 160 million tonnes of carbon each year.

If the polar ice caps were to melt then it could lift the lid of a new carbon sink capable of soaking up carbon dioxide.

What happens if the polar ice caps melt?

If all the ice protecting Antarctica, Greenland, and mountain glaciers around the sector were to melt, sea degrees might upward push about 70 meters (230 ft). the sea might cowl all of the coastal towns. And the land place would decrease considerably. but many cities, inclusive of Denver, might live to tell the tale.

How do melting ice caps affect the ecosystem?

Melting ice reasons more warming.

because they are darker in the shade, the ocean and land take in more incoming solar radiation and then launch the warmth to the environment. This reasons more global warming. in this way, melting ice causes more warming and so extra ice melts.

What one advantage of owning a solar car?

Answers

Answer:

The potential of energy availability at all locations where there is Sunlight

Explanation:

One advantage in owning a solar car is the potential of energy availability

The solar car source of energy is from the Sun which is readily available during the daytime where there is a clear sky. The energy from sunlight  is converted to to electrical energy by the photovoltaic cells on solar panels installed on the roof area of solar powered cars

The energy from the Sunlight is a form of renewable energy and therefore allows for better stability as well as the possibility of reuse of the energy

There are no emissions from the use of solar cars including noise, making the solar car very environmentally friendly.

Which type of reaction is described by the following equation Na2O (s) + 2CO2 (g) + H2) (g) Produces 2 NaHCO3 (s)

Answers

Answer:

If the reaction is going from left to right it would be synthesis, if going right to left it would be decomposition.

Explanation:

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

Left Side

Na = 2

O = 6

C = 2

H = 2

Right Side

Na = 2

O = 6

C = 2

H = 2

Ok so is balanced already, though initial equation in question had an error in regards to the left hand side the ) should have been an O.

Hmm

Na2O (s) + 2CO2 (g) + H2O (g) = 2 NaHCO3 (s)

If it was going from right to left would be decomposition

How many grams are in 0.572 moles of glucose, C6H12O6

Answers

Answer:

103.00

Explanation:

1 mole of Glucose

6 C = 6 * 12 = 72 grams

12H = 12 * 1 = 12 grams

6O = 6 * 16 =96 grams

Total          = 180 grams

0.572 moles of Glucose

1 mol of glucose = 180 grams

0.572 mols of glucose = x

x = 0.572 * 180

x = 103.00 grams

How many moles of neon (Ne) gas have a volume of 2.2 L and a pressure of
0.83 atm at 283 K?
(The universal gas constant is 0.0821 L.atm/mol.K.)
O A. 13 mol
O B. 0.11 mol
O C. 42 mol
O D. 0.079 mol

Answers

Answer:

D. 0.079 mol

Explanation:

This question involving the number of moles of neon (Ne) gas can be solved using the ideal gas law, also called the general gas equation.

The formula for the general gas equation is:

PV = nRT

Where;

P = pressure (atm)

V = volume (Litres)

n = amount of substance (mol)

R = ideal gas constant

T = temperature (K)

In this question, P is given as 0.83atm, V = 2.2L, R = 0.0821 L.atm/mol.K, T= 283K, n = ?

We calculate 'n' by making it the subject of the formula i.e.

PV= nRT

Divide both sides by RT, we have;

n = PV/RT

Hence, we input our values

n = 0.83 × 2.2 / 0.0821 × 283

n= 1.826 / 23.2343

n = 0.07859

Hence, n is approximately 0.079 mol

An electrical company charges 15 p per unit of energy (kWh).
Calculate the cost of running a 500 W freezer for a day. Show your working.

Answers

Answer:

180 p

Explanation:

Energy refers to the capacity of doing work.

Amount charged by an electrical company = 15 p per unit of energy (kWh)

As 1 W = 1000 kW,

[tex]500W=\frac{500}{1000}kW=0.5\,kW[/tex]

Also, 1 day = 24 hours.

Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour = [tex]15\times 0.5=7.5\,p[/tex]

Therefore,

cost of running a 0.5 kW freezer for a day ( 24 hours ) = [tex]7.5\times 24=180\,p[/tex]

Amount charged by an electrical company = 15 p per unit of energy (kWh)

As 1 W = 1000 kW,

[tex]500W=\frac{500}{1000}kW=0.5\,kW[/tex]

Also, 1 day = 24 hours.

Cost of running a 500 W freezer = 0.5 kW freezer for 1 hour = [tex]15\times 0.5=7.5\,p[/tex]

Therefore,

cost of running a 0.5 kW freezer for a day ( 24 hours ) = [tex]7.5\times 24=180\,p[/tex]

Calculate Rations. A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. if the input voltage is 120 V, what will the output voltage be?

Answers

Answer:

Output voltage = 600 V

Explanation:

Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = Voltage of input/voltage of output

10/50 = 120V/voltage of output

Voltage of output = 120 V/0.2

Voltage of output = 600 V
