Which elements would have properties similar to those of boron (B) ? Se , Li , and Be Al , Ga , and In C, N, and O Na , Mg , and
n200080 [17]

Answer:

option B= Al, Ga and In

Explanation:

Properties of Boron group:

  1. These elements are belongs to boron group which is thirteen group of periodic table. There are six elements are in this group boron, aluminium, gallium, indium, thallium and nihonium.
  2. They are also called p-block elements because their valance electrons are present in p subshell.
  3. All these elements have three valance electrons.
  4. Boron is metalloid while other elements are metals.
  5. Their oxidation state is +3 because of tendency to lose three valance electrons and create positive charge.
  6. Their atomic sizes increases down the group with increase of atomic number.
  7. Their ionization energies decreases down the group because of increase of atomic radius and ease of removing of electrons.

Answer:

Option A. Dense water floats.

Explanation:

Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.

However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.

A base has a molarity of 1.5M w.R.T the hydroxyl ion concentration. If 7.35 cm3 of this base is taken and diluted to 147 cm3, th
daser333 [38]

Answer:

0.077M is the concentration of the hydroxyl ion

Explanation:

Dilution factor is the ratio between the aliquot that is taken of a solution and the total volume of the diluted solution.

For the problem, dilution factor is:

7.53cm³ / 147cm³ =<em> 0.05122</em>

To obtain molarity of a diluted solution you must multiply dilution factor and initial molarity of the solution, thus:

1.5 M × 0.05122 = <em>0.077M is the concentration of the hydroxyl ion</em>
