nydimaria [60]2 years ago
4 0

Answer:

2HgO --> 2Hg + O2 is a decomposition reaction, in which mercury oxide is decomposed into the element mercury and oxygen gas. A decomposition reaction is one in which a more complex substance is broken down into its simpler components.

Hope this helps!

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (
SCORPION-xisa [38]

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

Molarity = \frac{moles}{volume(in L)}\\= \frac{0.5 moles}{2.00 L}\\= 0.25 M

Thus, we can conclude that molarity of this solution is 0.25 M.

Why do Group 12 elements have different properties than Group 13<br> elements?
blagie [28]
Group 12 Elements have two valence electrons while Group 13 Elements have three valence electrons.
Number of valence electrons tend to determine factors like reactivity. So elements with different number of valence electrons will have different properties.
That is why G12 and G13 have different properties

During an ice age, land can move and specific areas can be permanently changed. true or false
givi [52]

Answer: The given statement is true.

Explanation:

It is known that due to increase in temperature ice melts. Therefore, during ice age there is also melting of ice and solid state of water changes into liquid state of water.

Therefore, this water moves from its initial place and changes its position result in the change of land and specific areas.

Thus, we can conclude that the statement during an ice age, land can move and specific areas can be permanently changed is true.
