Mendeleev arranged the elements in rows in order of increasing mass so that elements with similar properties were in the same column.
So, the answer will be When Mendeleev organized elements in his periodic table in order of increasing mass, elements with similar properties were in the same Column.
Answer:
In the reaction ocurrs a nucleophilic substitution of a primary alkyl bromide, where the nucleophile is CH3O-.
Explanation:
Nucleophilic substitution is a type of substitution reaction in which a nucleophile replaces an atom or group in an electrophilic position of a molecule, called a leaving group.
It is a type of fundamental reaction in organic chemistry, where the reaction occurs on an electrophilic carbon. Although nucleophilic substitution reactions can also take place on covalent inorganic compounds.
Answer:
Explanation:
To convert from moles to grams, we must use the molar mass. This is found on the Periodic Table. Look for Phosphorous or P.
- Phosphorus (P): 30.973762 g/mol
We can use this number as a ratio.
Multiply by the given number of grams: 15.62
Flip the fraction so the grams of phosphorus cancel.
Divide.
The original measurement of grams has 4 significant figures, so our answer must have the same.
For the number we calculated, that is the ten thousandth place. The 9 in the hundredth thousandth place tells us to round the 2 to a 3.
There are 0.5043 moles of phosphorus in 15.62 grams.
The reaction will shift toward the reactants if the volume is cut in half.
<h3 /><h3>Reactants </h3>
The initial components of a chemical reaction are called reactants. Chemical bonds between reactants are broken and new ones are created in order to create products. Reactants and products are listed on the left and right sides, respectively, of the arrow in a chemical equation.
Substances on both sides of an arrow that points left and right are both reactants and products in a chemical process (the reaction proceeds in both directions simultaneously). A chemical equation that is balanced has the same amount of atoms of each element in the reactants and products. Around 1900–1920 is when the word "reactant" was first used. There are instances when the word "reagent" is interchangeable.
