Considering the Charles' law, the new temperature of the gas at 200 L is 546 K.

Charles' law establishes the relationship between the volume and the temperature of a gas sample at constant pressure and says that when the temperature is increased the volume of the gas also increases and that when it cools the volume decreases. That is, the volume is directly proportional to the temperature of the gas.

Mathematically, Charles's law is expressed as:

V÷T=k

where:

Analyzing an initial state 1 and a final state 2, it is fulfilled:

V₁÷T₁=V₂÷T₂

In this case, you know:

Replacing in the definition of Charles' law:

100 L÷ 273 K= 200 L÷T₂

Solving:

(100 L÷ 273 K)×T₂= 200 L

T₂= 200 L÷(100 L÷ 273 K)

T₂= 546 K

Finally, the new temperature of the gas is 546 K.

Answer:

KMnO4

Explanation:

For a compound of 100g

K has 24.74% or 24.74 g

=> 24.74/39.10 = 0.63

Mn has 34.76% or 34.76g

=> 34.76/54.95 = 0.63

O has 40.50% or 40.50g

=> 40.50/16 = 2.53

So K:Mn:O = 0.63:0.63:2.53

If divided by 0.63 => 1:1:4

Then the empirical formula is KMnO4

Consider the stoichiometry of the reaction, which is the ratio of reactant particles to product particles in the reaction. So in this reaction, the stoichiometry is:

2 : 1 : 2 : 2

Therefore, if you have 30 moles of water, than you have 30 moles of sodium hydroxide, 15 moles (30÷2) of hydrogen gas, and 30 moles of sodium.

The chemical equilibrium is also dynamic just like the physical equilibrium. Among the given conditions, the reaction is irreversible is not a condition for dynamic equilibrium. The correct option is C.

The chemical equilibrium is dynamic in nature. The observable properties of the system like pressure, concentration, colour, etc. become constant at equilibrium and remain unchanged thereafter.

It is in chemical equilibrium the rate of forward reaction becomes equal to the rate of reverse reaction (reversible). The chemical equilibrium can be attained only if the system is a closed one.

Some ionic compounds contain a roman numeral because they are formed from transition metals that can have different oxidation states or charges.

Transition metals have several valence electrons, which means they can lose different numbers of electrons and form ions with different charges.

For example, iron (Fe) can form two different ions, Fe²⁺ and Fe³⁺, depending on whether it loses two or three electrons, respectively. These ions have different charges and can form different ionic compounds with other elements.

To indicate the charge on the transition metal ion in an ionic compound, a roman numeral is added to the metal name. The roman numeral corresponds to the charge on the metal ion, and it helps to specify which ion is present in the compound.

For example, FeCl2 is iron(II) chloride, which contains the Fe²⁺ ion, and FeCl₃ is iron(III) chloride, which contains the Fe³⁺ ion. Without the roman numeral, it would be unclear which iron ion is present in the compound, and this could affect the properties and behavior of the compound.

Therefore, the use of roman numerals is important for accurately describing and understanding the composition of ionic compounds containing transition metals.

The alpha helix and beta sheet are found at the secondary level of protein organisation. The alpha helix and beta sheet are the two most common secondary structures found in proteins.

The primary structure of a protein is the linear arrangement of amino acids. In contrast, the secondary structure refers to the regular and recurring structural patterns that form due to hydrogen bonding interactions between the backbone atoms of the protein.

The alpha helix is a right-handed helix formed by a hydrogen bond between the carbonyl group of one amino acid and the amino group of another amino acid four residues away. On the other hand, the beta-sheet consists of two or more beta strands linked together by hydrogen bonds to form a flat, pleated sheet-like structure.

The substance that would be separated last by decreasing the temperature from its initial value depends on the specific system and the phase diagram of the substances involved.

In general, as the temperature of a system decreases, the substances with the highest melting or boiling points will be separated last, as they require the highest amount of energy to transition from a liquid or gas phase to a solid phase.

For example, if you have a mixture of water (H2O) and sodium chloride (NaCl) at room temperature and decrease the temperature, water will freeze into ice at 0°C (32°F), while sodium chloride will remain in a liquid state until it reaches its freezing point of 801°C (1474°F). Therefore, in this case, sodium chloride would be separated last by decreasing the temperature from its initial value.

So it is likely that some combination of these elements and their compounds were used to produce the red, green, and yellow fireworks.

The melting point of a liquid can vary widely depending on the specific substance. However, in general, liquids have a melting point at or above room temperature, since they are in a fluid state at that temperature.

For example, the melting point of water, which is a common liquid, is 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. However, there are many liquids that have much higher or lower melting points than water.

The mass of the gas released is 3.98 grams - 438 grams = -434.02 grams.

Mass is a measure of the amount of matter present in an object. It is the amount of inertia a body has, meaning it is the measure of the resistance of a body to change in its motion when subjected to an external force. Mass is usually measured in kilograms, grams, or pounds. Mass is distinct from weight, which is a measure of the force of gravity acting on an object.

This result is negative because the mass of the gas is not actually being weighed, but is instead being calculated by subtracting the mass of the tablet after the reaction from the mass of the tablet before the reaction. The negative result indicates that the mass of the gas released is less than the mass of the tablet before the reaction.

Answer:

This is a simple example of a two-player game known as the Prisoner's Dilemma. The payoffs represent the benefits or costs of different strategies chosen by the players. The equilibrium of the game is the combination of strategies that neither player has an incentive to change given the strategy of the other player.

In this game, both players can choose to either "Cooperate" or "Cheat". The payoffs for each combination of choices are given in the matrix below:

Player 2: Cooperate Player 2: Cheat

Player 1: Cooperate (5,5) (12,2)

Player 1: Cheat (2,12) (9,9)

The dominant strategy for both players is to "Cheat". This means that, regardless of the choice of the other player, each player will do better by choosing "Cheat" rather than "Cooperate".

However, if both players choose "Cheat", they will get a lower payoff than if they both choose "Cooperate". Therefore, there is an incentive for both players to choose "Cooperate" instead of "Cheat". This is the paradox of the Prisoner's Dilemma: even though both players would be better off if they cooperated, the dominant strategy leads to a suboptimal outcome.

The Nash equilibrium of the game is the combination of strategies in which neither player has an incentive to change given the strategy of the other player. In this case, the Nash equilibrium is the combination of "Cheat" and "Cheat" because this is the dominant strategy for both players, and there is no other combination of strategies that both players would prefer. However, the "Cooperate" and "Cooperate" outcome would be a more desirable outcome for both players, but they cannot achieve it without cooperation.

A hydrate is a compound containing a specific mass of water in the form of H₂O. To determine the molecular formula of the hydrate,[anhydrous solid⋅xH₂O.

], moles of water per mole of anhydrous solid (x). Step of the hydrate formula :

Considering a 210.4 g sample of Epsom salt hydrate, heating MgSO₄.xH₂O. releases water, so the mass of the resulting anhydrate is 120.4 g. What is the molecular formula of this hydrated sulfate?

= 210.4 g MgSO₄.H₂O. - 120.4 g MgSO₄

= 90 g H2O.

= 90 g H₂O/ (18 g/mol H₂O) = 5 mol H₂O.

= 120.4 g MgSO₄ /(120.4 g/mol MgSO₄ ) = 1 mol MgSO₄.

= 5 mol H₂O /1 mol MgSO₄ = 5:1.

Since there are 5 moles of H₂O for every mole of MgSO₄, the molecular formula is MgSO₄.5H₂O. There are therefore 5 molecules of water in the formula of hydrated sulphate.
