Answer : The conversion used is,
Explanation :
The conversion used :
For example : To convert 10 feet into inches.
From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be,
Final answer:
When converting from feet to inches, use the conversion factor 12 inches/1 foot. This way, the unit 'foot' cancels out and leaves 'inches', performing the conversion. An example is converting 5 feet to inches is 5 times 12, which equals to 60 inches.
Explanation:
When you're converting units, such as feet to inches, the main guideline is to set up your conversion factor in a way that cancels out the unit you want to convert from and leaves you with the unit you want to convert to. In this case, since you're converting from feet to inches, you'll be using the fact that there are 12 inches in 1 foot as your conversion factor. Therefore, when converting, the conversion factor should be set up as 12 inches/1 foot. This in essence means you're multiplying by the number 1, which doesn't change the value, just the units.
For instance, if you have 5 feet and you want to convert this to inches, you'll set your conversion factor up as 12 inches/1 foot, with inches in the numerator and feet in the denominator, to cancel out feet. Multiply 5 feet by the conversion factor (12 inches/1 foot), the result would be 60 inches. Here, the 'feet' units cancel leaving the answer in inches, completing the conversion.

Answers
6. Activation energy is the difference in energy between the reactant and the transition state. The energy of the reactant and the transition state are 5 kJ/mol and 15 kJ/mol respectively. The activation energy for this reaction is 10 kJ/mol.
7. The change in free energy for the reaction is the difference in energy between the reactant and the product. The energy of the reactant and the product are 5 kJ/mol and 10 kJ/mol respectively. The change in free energy for the reaction is 5 kJ/mol.
8. There are no intermediates involved in this reaction.
9. There is only one transition state involved in the reaction mechanism. The transition state is indicated by the highest point of the graph.
10. The reaction is endergonic overall. The energy of the product is higher than the energy of the reactants, which is only possible if energy is absorbed by the reaction.

Hello,
In this case, such nomenclature expresses the amount of both phosphorous and chlorine atoms via prefixes for the sub indexes of each atom into the molecule, thus, as phosphorous is prefixless one infers that there is just one phosphorous and five chlorides since the prefix for such atom is penta. Therefore, the correct formula is:
Hence, the answer is (a)

With the Ideal Gas formula.
Further Explanation
The ideal gas equation is an equation that presents the relationship between the pressure and volume of a gas with the temperature and the number of moles of the gas itself. This ideal gas equation is based on the laws of Boyle, Charles, and Avogadro.
This equation is generally written as
-PV = nRT
Boyle's Law (T = C)
Boyle's Law about the nature of gas was first created by Robert Boyle (1627¡1691). Boyle found experimentally that at a constant temperature, the pressure in a closed container would be inversely proportional to the volume of the gas. This means that if we press the gas and large volumes to small volumes, the gas pressure will rise, conversely if we expand the gas from small volumes to large volumes, the gas pressure will decrease. The process of pressing gas from large volumes to small volumes is called the compression process. While the process of changing the volume of gas from a small volume into a large volume is called the expansion process.
Gay Lussac Law (V = C)
The Gay Lussac Law was first coined by Joseph Louis Gay-Lussac (1778 - 1850) a chemist from France. Lussac's Gay Law states that under constant volume conditions, an increase in gas pressure will be directly proportional to an increase in gas temperature. This means that the gas in a closed container with a volume does not change (V0 = V1), so if the gas is heated from the initial temperature T0 to the final temperature T1 will cause the gas pressure also rises from the initial pressure (p0) to the final pressure (p1).
Charles Law (P = C)
Charles' ideal gas law is also called the law of constant pressure, first created by Jacques Alexandre Cesar Charles (1746 - 1823) a chemist from France. Charles's Law says "Under conditions of constant gas pressure, the volume of a gas will increase in proportion to the increase in temperature of the gas". This means that if we have a cylinder-piston system that can move up and down freely, then when the gas in the system is heated so that the temperature rises from T0 to T1, then to keep the gas pressure in the cylinder constant, the volume of gas will expand from the condition V0 to V1.

question no 1 answer is compounds
Final answer:
Elements combine to form millions of compounds. The force holding atoms together in these combinations are chemical bonds. Each electron has a negative charge, electrons are always moving, and have more energy the farther they are from the nucleus.
Explanation:
The elements can combine in many ways to create compounds, which amount to millions. When atoms connect or adhere to each other to shape those compounds, it happens through chemical bonds. In an atom, each electron has a negative charge, a characteristic that's vital for the creation of chemical bonds. Electrons are in constant movement, which means we cannot exactly determine their positions. As for the energy level of these electrons, those farther away from the nucleus have, in general, more energy than the ones located closer to the nucleus.
