Answer:
B. Convert mass percents to moles and then divide by the smallest mole value to get subscripts
Explanation:
The empirical formula is the smallest whole number ratio the elements in a compound can possess. According to this question, to derive the empirical formula of a compound from its percent composition of elements that make it up, the following steps are followed:
- First, since the elements are in percentage, one would assume the total mass of the compound is 100g and take each percentage as the mass of each element. For example, if a compound contains 16% oxygen, it means that 16g of oxygen is present.
- Next, we convert the mass of each element to moles by dividing the mass value by the molar mass of each element. For example, 16g of oxygen will be 16g/16g/mol = 1mol
- Next, we divide each mole value by the smallest mole value to get the subscript of each element that will be used in the empirical formula.
Answer:
To the right.
Explanation:
The chemical equilibrium is a state of a reactant system in which they are not observed changes as time goes by, even though the reaction continues. In other words, the chemical equilibrium is established when there are two opposite reactions which take place simultaneously at the same speed.
The variation in the concentration of any of the species involved in the equilibrium varies the value of the concentrations of the remaining species in the equilibrium.
In this case the concentration of one of the reaction reagents varies, increasing it since there is a greater amount of CO. This causes the balance to change to the products to compensate for the reaction. Then the balance goes to the right.
Explanation:
The lewis dot structure or electron dot structure is a notation that shows only the chemical symbol of the element surrounded by dots to represent the valence electrons.
- The chemical symbol represents the nucleus and all electrons except the valence electrons.
- The dots are arranged at the four sides of the symbol pairs called lone pairs.
- Those that are unpaired are called odd electrons.

A is the answer im pretty sure
Silver is the densest as it is lower on the periodic table containing more protons and nuetrons and electrons
