If the element has a charge of +2 it has lost two electrons giving it an overall positive charge making it a cation. In order to find the number of electrons, take the elements atomic number and subtract two since it lost two electrons
When a volcano erupts it releases a large amount of dust, smog, rock, and other materials. Basically, these bits and pieces float to form a metaphorical dust cloud. These clouds can often block out the sun like an ordinary cloud; however, because the cloud is dark, even less sun will be able to get through. So because the sun can't reach the ground, the temperature might decrease.
There would be a direct result as an increase in the solute temperature will result in increase in its solubility. A greater amount of solute molecules will possess more kinetic energy and will be distributed and in container.
The following reaction: H2 + I2 → 2HI, is an example of synthesis reaction
<u>Explanation:</u>
<u>Synthesis reaction:</u>
- In simple words, synthesis reaction can be stated as two or more material merge to form a new material.
- A synthesis reaction is always exothermic since they deliver power in the form of heat and light.
- When the metal and nonmetals are combined they produce an ionic compound.
- A synthesis reaction is essentially the reversal of decomposition reaction.
- The example of Synthesis reaction would be
- 2 H2(g) + O2(g) -->2 H2O(g)
- 3 H2(g) + N2(g)--> 2 NH3(g)
<u></u>
I think it would be these three answers ionic , covalent , and polar covalent
