The type of chemical bond depends on the substances taking part in it. If the substances are metal and non-metal, then the bond between them is ionic. If two substances are metal, then the bond between them is metallic. If two substances are non-metal, then the bond is covalent.
So basically put this:
Metal + Nonmetal = Ionic
Metal + Metal = Metallic
Nonmetal + Nonmetal = Covalent
A. It absorbs energy.
reactants are located on the left side of the equation, meaning energy among with other reactants were needed to get the reaction going, so it absorbed energy, which is also the endothermic process. The opposite of that would be having energy on the right side with the products which means that the reaction would've released energy which is the exothermic process. Hope this helps!
Answer:
No
Explanation:
It is given that :
Amount of the clear aqueous solution = 4 L
Temperature of the clear solution = 22°C
The solution remain clear even after an unknown amount of X compound is dissolved in the solution.
Then the water is evaporated under vacuum and the remaining precipitates weighs 0.56 kg.
Therefore, from the above data, we cannot calculate the solubility of the compound X that is added to the clear aqueous solution at 22°C.
The substance which gets dissolved is known as solute and the substance where the solute is dissolved is known as the solvent.
The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
Circular lines on topographic map is called Contour lines these lines shown on two dimension map and depict elevation on the ground . the distance of each contour line is set to represent a certain level of elevation with zero being sea level . mostly map use distance between coutour lines is 10 m
