Answer:
D
Explanation:
A synthesis reaction is a reaction in which two or more reactants combine to form a given product.
If we look closely at option D, you will notice that sulphur and oxygen combined together to form sulphur dioxide. That is a typical example of chemical synthesis.
Hence;
S + O2 ----->SO2 is a synthesis reaction.
Answer:
it depends on the assignment but im down
Explanation:
Starting mass: 294
Mass ratio: 3/5
The molar mass of sodium is 22.99 ㅤ ㅤ ㅤ 22.99 (28) = 643.72 mol now multiply by avogrados number to find the number of atoms. ㅤ ㅤ ㅤ 643.72 (6.022 x 10^23) = 3.88 x 10^26 number of atoms
Since no choices are given, I will describe the reactivity of the element chlorine. A halogen is example of
nonmetal. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine. An example of is reactivity is the monochlorination of
an alkane, which involves substituting one of the hydrogen atom in the alkane and
exchange it with a chlorine atom.
CH₄ + Cl₂ → CH₃Cl + HCl
The H in methane is substituted with the
Cl in chloride.
