Answer:
Explanation:
The reaction is a precipitation reaction. In other words, the two aqueous solutions react to give the solid salt, potassium chloride (KCl) in this case.
Because the reaction product is a solid, the net ionic equation can be written as:
This is the resultant equation after removing spectator ions: sulfate and strontium.
The number of atoms present in carbon, specifically Carbon-12, is the number of atoms present in 1 gram of the substance. One moles of the substance weighs approximately 12.01 g/mole. The unit suggests that every mole of carbon weighs 12.01 grams.
Answer:
Answer in explanation
Explanation:
The reactivity or passiveness of an element depends solely on how close it is to attain a noble gas configuration. This means the closer an element is to attain a noble gas configuration, the greater its reactivity in both direction, positively or negatively.
Alkali metals belong to group 1 of the periodic table while halogens belong to group 17 of the periodic table. This means they are just one electron away from achieving the stability of a noble gas configuration. While alkali metals need to lose one electron to form a univalent positive ion, halogens news to gain one electron to form a univalent negative ion.
They tend to go about this vigorously and as such undergo several chemical reactions because of that single electron they neeed.
A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
Strong Acid has a lower pH level than a weak acid, weak acid pH level will be closer to 7 than the strong acid. Weak acid does not dissociate completely, therefore a weaker proton donor, thus higher pKa. Strong acids dissociates completely and release all of their hydrogen atom when dissolve in water.
