To which of the three main chemical classes does Mercury (Hg) belong?
a) It's not an element in the periodic table
b) Metalloids
c) Non-metals
d) Metals

Answers

Answer:

Metals

Explanation:

It is a transition metal

The periodic table has a lot of different properties in how it is presented, one of these, is that the elements are separated in blocks by their properties.

From its position in the table, we can see that the correct option is d) metals.

The general way of knowing if an element is a metal or not, is to look if it is the D block in the periodic table.

This block contains all the transition metals (not all the metals) but every element in it is a metal. If we look for the mercury, we can see that it is in block D, just next to gold (Au).

Just from this, we can conclude that mercury is a metal, so the correct option is d.

Why the bond in water molecule os polar covalent bond, while than in chlorine molecule is pure covalent bond? Give reason? ​

Answers

Explanation:

The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side). We say that the water molecule is electrically polar.

1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g

Answers

Molarity is a unit of concentration defined as the number of moles of solute (the substance being dissolved) per volume of solution (the solvent in which all the solute is dissolved). Mathematically, molarity is expressed as

[tex]M = \frac{\text{ mol solute}}{\text{ L solution}}[/tex].

In this question, we are given the molarity and the volume of a solution of NaCl. We can use this information to calculate the number of moles of NaCl present in the solution. Rearranging the equation to solve for moles of solute, we multiply the molarity by the volume of the solution (the units for volume must be in liters, so 125 mL is expressed as the equivalent 0.125 L):

[tex](8.59 \text{ M})(0.125 \text{ L}) = 1.07 \text{ moles of NaCl}.[/tex]

The question asks for the number of moles of NaCl in this solution, so number 3 would be correct.

Why can more sugar be dissolved in hot water than cold water (more solute be dissolved in hot solvent then cold solvent)

Answers

sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. when water is heated, the molecules gain energy and because of that, move faster. as they move faster, they come in contact with the sugar more often, causing it to dissolve faster.

Compare the seasons on Titan to the seasons on Earth.

After six hours, the researcher observes and sketches the two cells as shown. What change in the cells occurred during the six hours the cells remained undisturbed? A.Osmosis occurred in the salt water cell sample because the water from inside the cell moved out of the cell to a lower concentration, causing the cell to shrink. B.Osmosis occurred in the freshwater cell sample because the water from outside the cell moved into the cell to a higher concentration, causing the cell to grow. C.Osmosis occurred in the salt water cell sample because the salt from outside the cell moved into the cell to a lower concentration, causing the cell to shrink. D.Osmosis occurred in the freshwater cell sample because the salt from inside the cell moved out of the cell to a higher concentration, causing the cell to grow.
