What is the attraction between molecules within a substance called? adhesion capillary action cohesion polarity.

the rocky planet was exposed to harsh and forceful solar winds, which blew the Martian atmosphere away.

Another option for thickening the atmosphere of Mars, and, in turn, raising the temperature of the planet, would be to set up solar-powered, greenhouse-gas producing factories.

Considering the definition of ideal gas and gas laws, The Ideal Gas Law not apply and gases are considering real under conditions of high pressure low pressure.

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other.

In other words, an ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces, so they do not interact with each other.

Gases in general are ideal when they are at high temperatures and low pressures.

On the other hand, the gas laws are a set of chemical and physical laws that allow us to determine the behavior of gases in a closed system. The parameters evaluated in these laws are pressure, volume, temperature, and moles.

Summary

The Ideal Gas Law not apply and gases are considering real under conditions of high pressure low pressure.

Answer:

its A and D

Explanation:

Answer: Neutral

Explanation: This is because, in the ph scale, greater than 7 indicates base or alkaline (basic), while less than 7 indicates that it is acidic.

Based on the stoichiometry of the reaction, 15.27 g of Sulfur are required to produce 42.0 g of FeS.

A stoichiometry of a reaction shows the ratio in which reactant molecules will combine to form products.

The balanced equation of the reaction is given below:

Fe + S -----> FeS

Molar mass of sulfur = 32 g

molar mass of iron = 56 g

molar mass of FeS = 88 g

32 g of sulfur produces 88 g of FeS

mass of sulfur that will produce 42.0 g of FeS = 32/88 * 42 = 15.27 g

Therefore, 15.27 g of Sulfur are required to produce 42.0 g of FeS.

Answer:

transpiration

Explanation:

Transpiration is when water moves up a plant stem, because water has surface tension due to cohesion.

In water, the H is slightly positive and the O2 are both slightly negative. This creates bonds between the H and O of another molecule. This causes water to be sticky, and when water moves up a plant, other molecules are also pulled up.

3.The further out and the closer the the equator a place on Earth is the warmer it is due to the fact that the sun directly hits countries on the equator and takes in heat faster then the north and south pole. Countries on more of a curve are colder due to the fact they are more curved and it is harder for the heat to be taken in at a curve.

B is center point line passing through earth and it's placed right infront of sun so b would have highest temperature

The solute in this case would be sodium chloride and sucrose.

Solutes are substances capable of dissolving in solvents to give homogenous mixtures known as solutions.

In this case, both sodium chloride and sucrose were added to water - water is acting as the solvent.

Sodium chloride is soluble in water and so also is sucrose.

Thus, a homogenous mixture of sodium chloride and sucrose would result.

Answer:

answer in picture

Explanation:

When temperature increases, the air molecules gets energy. The air molecule starts moving randomly. The pressure is increased in the tire.

Entropy is defined as a measure of randomness or disorder of a system. disorder increases over time. Energy disperses.

In tire, it is filled with air molecules, its nothing but oxygen, nitrogen, sulpurdioxide, carbondioxide etc. when the outer side temperature increases, tire starts heating.

Heat is nothing but one type of energy, energy will transfer in to molecule. Molecule starts vibrating, hitting to walls this will increases the temperature and pressure increases.

Thus, if outer temperature increases. Pressure also increases.

I have 22.4 litre of methane gas

Answer:

The  percent composition of glucose  in the  mixture  is 85 % (Answer E)

Explanation:

"percent  composition of glucose = (mass of glucose /  mass  of the mixture) x 100

Step 1:  calculate the mass  of glucose ( C6H12O6)

mass of glucose =  moles of glucose  x  molar mass  of glucose

molar  mass of C6H12O6  = [( 12 x6) + ( 1  x12) + ( 16 x6)= 180 g/mol

mass  is therefore= 1.3 moles x 180g/mol = 234  grams

Step 2: calculate  the percent composition

= mass of glucose /mass of mixture x 100

= 234 g/276 g  x 100  = 85 %(answer E)"

Answer:

(80.0, 20.0) The statement states that 80% of the compound is carbon. To acheive the amount of carbon in a 100 g sample, you need to multiply the weight of the sample by the percentage of carbon in the compound. Recall that 80%=80/100=.8 .8*100g=80g of carbon. The same process goes for the hydrogen. .2*100g=20g hydrogen.  Explanation:
