A certain gas is present in a 15.0 LL cylinder at 2.0 atmatm pressure. If the pressure is increased to 4.0 atmatm the volume of
Helga [31]

Explanation:

According to Boyle's law,  pressure of a gas is inversely proportional to its volume at constant temperature and moles.

Mathematically,       P = \frac{k}{V}

where,     k = proportionality constant

Also, formula for initial pressure and volume is as follows.

              P_{i} = \frac{k_{i}}{V_{i}}

or,           k_{i} = P_{i} \times V_{i}

                          = 2 atm \times 15 L

                          = 30 atm L

Now, we will calculate the value of k_{f} as follows.

             k_{f} = P_{f} \times V_{f}

                         = 4 atm \times 7.5 L

                         = 30 atm L

Hence, as k_{i} = k_{f} this means that it signifies that gas obeys boyle's law.

When a radioactive isotope releases an alpha particle, the atomic number of the atom is (2 points)
natali 33 [55]
When alpha decay takes place, two protons and two neutrons are forcefully ejected from the nucleus in a way that looks very similar to a Helium nucleus. This type of decay causes the atomic mass of the parent particle to drop by four (four particles lost), but the atomic number drops by only two (two protons lost). Therefore, your answer is C.

The metric prefixes which is not one multiple of ten when moving forward or backward between prefixes is: none of the above

Option c is the correct answer

<h3>What is metric prefix?</h3>

A metric prefix simply refers to a unit prefix that precedes a basic unit of measure to indicate a multiple or sub-multiple of the unit.

So therefore, the metric prefixes which is not one multiple of ten when moving forward or backward between prefixes is: none of the above

Consider the structures of benzaldehyde and benzyl alcohol. Benzene ring with a CH2OH attached Benzene ring with an aldehyde gro
damaskus [11]

Answer:

no equivalent peak, upfield between 0 and 3 ppm

Explanation:

NMR stands for nuclear magnetic resonance. It is a spectroscopic technique that is used for observing the local magnetic fields around an atomic nuclei. It is used to study the chemical, physical and biological properties of the matter.

In the context, the structures of the benzaldehyde and the benzyl alcohol are distinguished by the proton NMR. The hydrogen atom of aldehyde appears downfield between 9 and 11 ppm and also there is no equivalent peak for the alcohol.

The methylene hydrogens will only be significant upfield between the 0 and 3 ppm peak between the given structures.
