Let's say one of our bicycles tires has a volume of 30.0 Liters at 300 K. What will happen if
we double the volume?

Answers

Answer:

I think that temperature will be cut in half.

When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!

How many miles are in 27.4 g of NO2

Answers

Answer:

0.59 moles

Explanation:

Given mass = 27.4 g

Molar mass of NO₂ = 46 g/mol

We need to find the number of moles. We know that,

No of moles = given mass/molar mass

Put all the values,

[tex]n=\dfrac{27.4}{46}\\\\n=0.59[/tex]

Hence, there are 0.59 moles of NO₂ .

what is the difference between autotrophs and heterotrophs?

Answers

Answer:

Autotrophs have the ability to synthesize their own food from the substances surrounding them. Examples of this are photosynthesis or chemical energy. Heterotrophs cannot synthesize their own food. They have to get their nutrition from other animals or plants.

In shorter terms, autotrophs are plants. Heterotrophs are humans.

If I have 4.4 moles of nitrous oxide (laughing gas) that is kept at 32.9 °C in a container under 1.6 atm, what is the volume of the container? (R = 0.0821 (L*atm)/(mol*K))

Round your answer to 1 decimal place.

Answers

Answer:

Explanation:

Using the ideal gas equation as follows:

PV = nRT

Where:

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

Based on the information provided in this question;

P = 1.6atm

n = 4.4 moles

R = 0.0821 L*atm/mol*K

T = 32.9°C = 32.9 + 273 = 305.9K

How many moles of Chlorine gas are required to produce 5.35 moles of NaCl in this
reaction?

Answers

Answer:

2.675 moles of Chlorine gas are required

Explanation:

Chlorine gas, Cl2, reacts with NaBr to produce NaCl and Br2 as follows:

Cl2 + 2NaBr → 2NaCl + Br2

Where 1 mole of chlorine gas produce 2 moles of NaCl

Thus, to produce 5.35 moles of NaCl are required:

5.35mol NaCl * (1mol Cl2 / 2mol NaCl) =

2.675 moles of Chlorine gas are required

At which position in its orbit was the Moon located during the 2015 supermoon total lunar eclipse?

Answers

On September 27, 2015, a rare total lunar eclipse of a supermoon occurred. A supermoon occurs when the entire lighted half of the Moon faces Earth (full Moon phase) and the Moon is at its closest point to Earth in its orbit.

The moon was located at position C in its orbit during the 2015 supermoon total lunar eclipse.

What is a supermoon lunar eclipse?

A supermoon can be described as a full moon that nearly coincides with perigee which is the closest that the Moon comes to the Earth in its elliptic orbit as results in a slightly larger-than-usual apparent size of the lunar disk can be viewed from the earth.

Perigee syzygy is the technical name of the Earth-Moon-Sun system or a full Moon around perigee. The association of the Moon with oceanic and crustal tides claims that the supermoon phenomenon can be associated with an increased risk of events such as volcanic eruptions and earthquakes, but no such connection has been found.

In the 21st century, there are 87 lunar eclipses in total, of which 6 are micro moons and 28 are supermoons. A supermoon lunar eclipse was seen in the September 2015 lunar eclipse.

A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
to 500 mL?

Answers

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml.  V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

How many moles of hypomanganous acid, H3MnO4, are contained in 22.912 g?

Answers

Answer:

0.188mol

Explanation:

Using the formula as follows:

mole = mass/molar mass

Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)

= 3 + 55 + 64

= 122g/mol

Mass of H3MnO4 is given as 22.912 g

Hence;

moles = 22.912 ÷ 122

number of moles = 0.188mol

What is the molarity when 25.0 g of the compound NaClO3 is placed in 85.0 mL of solution?

Answers

Answer: Molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.

Explanation:

Given: Mass = 25.0 g

Volume  = 85.0 mL (1 mL = 0.001 L) = 0.085 L

Molarity is the number of moles of a substance divided by volume in liter.

Hence, molarity of given solution is calculated as follows.

[tex]Molarity = \frac{mass}{Volume (in L)}[/tex]

Substitute the values into above formula as follows.

[tex]Molarity = \frac{mass}{volume (in L)}\\= \frac{25.0 g}{0.085 L}\\= 294.12 M[/tex]

Thus, we can conclude that molarity when 25.0 g of the compound [tex]NaClO_{3}[/tex]is placed in 85.0 mL of solution is 294.12 M.

milk sours because of a chemical reaction that takes place between some of the chemicals that make up the milk. Why does a carton of milk left out on a countertop sour sooner than a carton of milk left in the refidgerator

Answers

Answer: A lower temperature slows down the reaction that causes souring, making the milk last longer in the refrigerator.

Explanation:

Milk is made up of different constituents which includes:

--> water,

--> fat,

--> proteins,

--> lactose (milk sugar) and minerals (salts).

Milk is also considered to be a heterogeneous mixture because of the presence of fat and water which are two immiscible liquid phases that are present.

Milk contains a sugar called lactose. It also contains harmless bacteria called lactobacillus, which uses lactose for energy and creates lactic acid as a by-product. It is the lactic acid which makes milk taste sour. Therefore when milk is kept at a LOWER temperature, these bacteria growths are limited but at a HIGHER temperature such as room temperature, the growth is increased. As they increase in growth, the bacteria makes use of the lactose for energy and creates lactic acid as a by-product as earlier mentioned, leading to the sour taste observed.
