Chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms. Chemical reactions are represented by balanced chemical equations, with chemical formulas symbolizing reactants and products. For specific chemical reactants, two questions may be posed about a possible chemical reaction. First, will a reaction occur? Second, what are the possible products if a reaction occurs? This
Answer:
Iodine (I)
Explanation:
The atomic mass of Arsenic (As) is 74.92 amu. Also, we know that Halogen Group consists of following elements.
Fluorine, Chlorine, Bromine, Iodine, Astatine and Tennessine
And in given four options only Chlorine and Iodine belongs to halogen family. And we know that the atomic mass of chlorine is 35.45 amu which is less than that of Arsenic, therefore Iodine with atomic mass of 126.90 amu is the correct answer.
Answer:
Mixtures
Explanation:
Matter can be classified as a compound and a mixture.
This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
