Answer:

sorry we don't know the answer.

Answer:

0.083 mol

Explanation:

Molar volume of gas at r.t.p = 24 dm³

Number of moles = volume(dm³) / 24

Number of moles = 2/24 = 0.083...

Answer:0.58 atm

Explanation:see attached photo

Answer:

\(P=0.583atm\)

Explanation:

Hello,

In this case, by using the ideal gas equation:

\(PV=nRT\)

We can compute the pressure as shown below, considering the given data and absolute temperature:

\(P=\frac{nRT}{V}=\frac{0.325mol*0.082\frac{atm*L}{mol*K}*(35+273)K}{14.08L}\\ \\P=0.583atm\)

A model can only have a certain number of factors, and most models assume that these factors are static, which might limit how accurately a model can simulate reality.

A scientific model is a representation of an idea, a system of ideas, or different types of processes or events that can be in the mathematical form or physical form.

Although models are incredibly useful, they do have some drawbacks. Details—All of the information about the items that models represent cannot be included. Maps, for instance, cannot depict all the specifics of the earth's features, such as mountains, valleys, etc.

Answer:

268ml

Explanation:

What would the volume of a gas be at -150C, if it has volume of 693ml at 45.0C?

V and T are related as V =kT

first, change all C into K since these are gas laws!

45C =45+273 =318K

-150C =-150+273 =123K

now 693ml=kX318

so k=693/123 =2.18

so new V=2.18 X 123=268ml

False. wood to energy source can release carbon dioxide when it is burned.so it can be considered as a renewable energy source.

Burning wood can release lots of carbon dioxide comparatively to other fossil fuels. plants and trees are considered as renewable energy source. because when it is cut again it grows. its is less dense energy source. Many solar power plants can convert carbon dioxide into fuels. and it can be recycle to other chemicals. Renewable energy emits between 11 to 750 g of carbon dioxide. As long as trees planted its a great source of renewable energy source. This also have many other environmental benefits.

Answer:

a. pH = 2 b. pH = 3 c. pH = 1 d. Unanswerable

Explanation:

pH = -log[H+] OR pH = -log{H3O+]

                    and inversely

pOH = -log[OH-]

1. Determine what substance you are working with, (acid/base)

2. Determine whether or not that acid or base is strong or weak.

a. 1.0 x 10^-2M HCl

HCl is a strong acid, therefore it will dissociate completely into H+ and Cl- with all ions going to the H+, therefore, the concentration of HCl and concentration of H+ are going to be equal, meaning we simply take the negative logarithm of the concentration of HCl and that would equal pH

pH = -log[H+]

pH = -log(1.0x10^-2)

pH = 2

b. 1.0 x 10^-3M HNO3

HNO3 like part a, is a strong acid, therefore it would simply require you to take the negative logarithm of the concentration of the compound itself, to find its pH.

pH = -log[H+]

pH = -log(1.0 x 10^-3)

pH = 3

c. 1.0 x 10^-1M HI

Like the previous parts, HI is a strong acid

pH = -log[H+]

pH = -log(0.10)

pH = 1

d. HB isn't an element, nor is it a compound so that would be unanswerable.

Answer: D

Explanation:

I would say D, because it makes sense for the temperature to decrease with depth because less sunlight means less heat. I'm not sure about the salinity 100% but I think it increases.

In refrigeration, the refrigerant is a substance that absorbs heat from the surrounding and dissipates it to produce cooling. The correct option is a. True.

What is thermal balance?

The thermal balance in a refrigeration system is achieved when the system has reached a stable state, that is, the amount of heat absorbed by the refrigerant is equal to the heat rejected by the refrigeration system. During the compression process, the refrigerant is compressed and pumped into the condenser where it undergoes condensation, i.e., it changes from a gas to a liquid by releasing heat.

In the condenser, the refrigerant rejects the heat that it absorbed in the evaporator and releases it to the surrounding. The condensation process reduces the number of vapor molecules in the refrigerant, which leads to an increase in the number of liquid molecules.

Therefore, the number of vapor molecules that condense into liquid equals the number of vapor molecules that the compressor pumps into the condenser. This is because the compressor has to maintain a constant flow of refrigerant in the refrigeration system to achieve thermal balance.

Hence, the statement is a) true.

Explanation:

222.01758 g/mol

3.1Computed Properties

To calculate the heat transferred, we can use the formula:

Q = m * c * ΔT

Where:

Q is the heat transferred

m is the mass of the water

c is the  specific heat capacity of water

ΔT is the change in temperature

Given:

Mass of water (m) = 160 grams

Specific heat capacity of water (c) = 4.18 J/g°C

Change in temperature (ΔT) = 27°C - 18°C = 9°C

Substituting the values into the formula:

Q = 160 g * 4.18 J/g°C * 9°C

Calculating the expression:

Q = 6028.8 J

Therefore, the heat transferred is 6028.8 Joules.

Explanation:

To know the distance, you need to be clear in the concept of distance.

According to the physics, the distance is a measurement that refers to the fact of how much an object has move from one point to another.

In this case, we have a person named Steve and he's walking through several points.

To calculate the distance that he moved, you just need to sum all the values of distance. In this case, it's not neccesary to do calculations regarding the components of the x or y axis, because we are not talking about displacement, where it actually counts. But in this case, we just need all the covered distance that Steven walked since the beggining.

So, no more talk, let's do calculations:

The mass of carbon dioxide in this is 264 g according to the given data.

The molar mass is basically the total mass in grams of the atoms that make up a molecule per mole. Molar mass is measured in grams per mole.

Combustion is the process of burning glucose in the presence of oxygen.

The balanced reaction is

\(C_6H_1_2O_6+6O_2---- > 6CO_2+6H_2O\)

As a result, each mole of glucose requires six moles of oxygen molecules.

Glucose has a molar mass of 180g per mole.

As a result, the reaction will be completed, with one mole of glucose reacting with six moles of oxygen to produce six moles of Carbon dioxide and six moles of water.

Carbon dioxide produced mass = moles X molar mass = 6 x 44 = 264 g

Thus, 264g will be the mass of the carbon dioxide produced.

Explanation:

To find the molecular formula, we would need to multiply the empirical formula by the whole number required to reach the molar mass of 62.00 g, which is likely to be C2H4O2.

To obtain the empirical formula, the percentage composition of each element must be converted to moles and divided by the smallest number of moles obtained. From the empirical formula, the molecular formula can be determined by multiplying the empirical formula by the whole number required to reach the desired molar mass.

The molar mass is the mass of a substance in grams that contains Avogadro's number of entities of that substance. It is usually expressed in units of grams per mole (g/mol). The molar mass is used to convert the amount of a substance in moles to its mass in grams.

Consider your personal preferences first because the colors you use in your home need to reflect those preferences as well as fit in with your lifestyle.

Light has an influence over the colors that can make them look stunning as well as dull. Different types of light sources such as incandescent, fluorescent, halogen, or LED will affect the way a color appears.

The orientation of the room such as the direction it faces or how much natural or artificial light is available can also affect how colors will appear in the room. So, consider the room specifications as well.

Consider fixed as well as furnished elements and accessories as they too have color. Take them into consideration to ensure that camouflaging or clashing doesn’t happen.

Consider the texture of walls whether they are smooth, rough, or in between. The texture will change the appearance of the color. Smooth walls will appear lighter while rough walls will appear darker.

Consider the kind of mood you want to set in a particular room. Different colors as well as their hues and combinations emote different feelings.

Consider the finishing if the paint whether to use gloss, semi-gloss, or satin to name a few. The finish of the t will have a lot to do with the final look of your color.
