Answer:

All the given elements belong to the second period of the periodic table

Explanation:

Let's locate the elements with the given atomic numbers:

  • Z = 3, this corresponds to lithium (Li);
  • Z = 4, this corresponds to beryllium (Be);
  • Z = 5, this corresponds to boron (B);
  • Z = 6, this corresponds to carbon (C);
  • Z = 7, this corresponds to nitrogen (N);
  • Z = 8, this corresponds to oxygen, (O);
  • Z = 9, this corresponds to fluorine, (F).

Now notice that each of these 9 elements can be found in the same row of the periodic table. This is period 2. We may then summarize that all of these elements belong to the same period, period number 2.

When the pressure on 2.5 liters of oxygen is decreased from 2.0 atm to 1.0 atm, the volume of the gas
uranmaximum [27]

Answer:

volume of the gas is 5.0L

Explanation:

Using Boyle's law that state the pressure of a gas is inversely proportional to volume of it occupies when temperature is constant, it is possible to write:

P₁V₁ = P₂V₂

<em>Where P is pressure, V is volume and 1 and 2 are initial and final states.</em>

<em />

If initial volume is 2.5L, initial pressure is 2.0atm and 1.0atm is final pressure, final volume is:

2.0atm*2.5L = 1atm V₂

5.0L = V₂

Thus, <em>volume of the gas is 5.0L</em>.

Would you expect an organic compound to be soluble in water why
RSB [31]

Answer: All organic compound depends on  H-bonding with water. more stronger H-bonding with water more will be soluble.

Explanation:

1. It depends primarily upon the function groups of that compound. It also depends on the size of the compound.  

2. some organic compound which soluble in water for example: alcohols, ethers, carboxylic acids.  Because of the functional groups attached to the organic structure (the C-H backbone) are what effect the solubilities.Like carboxylic acids and alcohols form hydrogen bonds with the water, helping to solubilize it.  

3. Take alcohols for example: methanol, ethanol, and isopropanol are all completely soluble in water. By the time you get to butanol and some of the larger alcohols, including those with more complex structures, they tend to be less soluble.
