Answer:

an ideal gas does not exist except as a conceptual notion, an ideal. Physicists and chemists idealized the behaviour of real gases so that they could explain these phenomena. Under conditions of low pressure and high temperature, all gases behave like real gases, even gases such as UF6 .

Answer:

hydropowered

Explanation:

 took the test

Hydropower is the energy source that produces the least amount of air pollution. Therefore, the correct option is option D.

Energy is The capacity or ability to do tasks, such as the ability to forcefully move an object. Energy can exist in a multitude of forms and can change from one to another, including thermal, mechanical, chemical, and nuclear energy. The flow of electric charges known as electrons is what generates electrical energy.

Energy is utilised to make a wide range of goods, power transportation, and power the appliances we use to heat and light our houses. The production of electricity is the main purpose of these various energy sources. All of these many energy sources contribute to the electrical power reserve that is then distributed to various locations via high-powered lines. Hydropower is the energy source that produces the least amount of air pollution.

Therefore, the correct option is option D.

Answer:

367.1 cm³

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 300 cm³

Initial temperature (T₁) = 40 °C

Final temperature (T₂) = 110 °C

Final volume (V₂) =?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273.15

Initial temperature (T₁) = 40 °C

Initial temperature (T₁) = 40 °C + 273.15

Initial temperature (T₁) = 313.15 K

Final temperature (T₂) = 110 °C

Final temperature (T₂) = 110 °C + 273.15

Final temperature (T₂) = 383.15 K

Finally, we shall determine the final volume (i.e the new volume) of the balloon. This can be obtained by using the Charles' law equation as illustrated below:

Initial volume (V₁) = 300 cm³

Initial temperature (T₁) = 313.15 K

Final temperature (T₂) = 383.15 K

Final volume (V₂) =?

V₁/T₁ = V₂/T₂

300 / 313.15 = V₂ / 383.15

Cross multiply

313.15 × V₂ = 300 × 383.15

313.15 × V₂ = 114945

Divide both side by 313.15

V₂ = 114945 / 313.15

V₂ = 367.1 cm³

Therefore, the new volume of the balloon is 367.1 cm³

According to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

According to the given chemical equation, 70.906 g of chlorine gives 117 g sodium chloride, thus, 2.4 g of sodium chloride will be produced, when 2.4×70.906/117= 1.45 g of Cl₂ reacts.

Thus, according to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.

Answer:

See explanation

Explanation:

We have been told in the question that the equation of the reaction is; 1 slice of cheese + 2 slices of bread = 1 Grilled cheese sandwich ( mole ratio is, 1:2:1) .

Then the reagents are 10 slices of cheese 30 slices of bread. It then follows that 10 slices of cheese should be combined with 20 slices of bread according to the mole ratio.

However, we have 30 slices of bread and 10 slices of cheese so cheese is the limiting reactant while bread is the reactant in excess.

Yes, the number of glilled chese sandwishes he can make is decided by the limiting reactant because it gets used up most.

Explanation:

Answer:

the particels becomes loose and wild, making gas happen when it is heated up

Liquids evaporate faster as they heat up and more particles have enough energy to break away. The particles need energy to overcome the attractions between them. At this point the liquid is boiling and turning to gas.

Answer:

The added salt will sink to the bottom

Explanation:

A saturated solution is that solution that contains the maximum amount of solute it can dissolve and ,hence, will no longer dissolve any more solute. This question is describing a water solution that is "saturated", this means that water can no longer dissolve any more solute because it has reached the maximum solute limit it can contain.

Hence, adding more solute to a saturated solution like the WATER being described in this question will result in the solute forming a PRECIPITATE at the bottom of the solution. Hence, in this water solution, adding salt to the saturated water solution will result in the added salt sinking to the bottom.

Explanation:

Answer:

1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

1. D

2. C

Explanation:

1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.

2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.
