• An element in group 2, period 4 has similar properties with

babymother [125]

Answer: Elements in Group 2

Explanation: The periodic table was arranged by Dmitri Mendeleev specifically around similarites in their chemical behaviors. He found that as atomic number increases, at some point an element starts to react in a manner similar to a previous one. When that happened, he would place the larger element under the smaller one, and eventually noticed a periodicity in the table. Elements in a column (Groups) had similiar chemical properties. We know today that these similarities are due to the electron configuration, and that these configurations repeat themselves. He left gaps in the table when he could find an existing element with properties similar to others in that group. I big leap of faith, but it worked. Elements for those missing boxes were eventually discovered.

The property which primarily controls how much water can be present as a gas is:

Assoli18 [71]

The temperature of the air is the property which primarily controls how much water can be present as a gas.

Meteorology is the study of the atmosphere. It primarily focuses on weather which is defined as the condition of the atmosphere at a certain time and place. It changes every day depending on earth location. There are five factors that affect weather namely, temperature, pressure, humidity, wind and precipitation.

The question above primarily talks about humidity-the amount of water vapor in the air. As the temperature increases, the air or gas can hold more water. The warmer the air is, the more water it can possibly hold as vapor.

According to the following reaction, how many grams of iron(II) chloride will be formed upon the complete reaction of 21.6 grams

velikii [3]

Answer:

37.58 g of FeCl₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe + 2HCl —> FeCl₂ + H₂

Next, we shall determine the mass of HCl that reacted and the mass of FeCl₂ produced from the balanced equation. This is can be obtained as follow:

Molar mass of HCl = 1 + 35.5 = 36.5 g/mol

Mass of HCl from the balanced equation = 2 × 36.5 = 73 g

Molar mass of FeCl₂ = 56 + (2×35.5)

= 56 + 71

= 127 g/mol

Mass of FeCl₂ from the balanced equation = 1 × 127 = 127 g

SUMMARY:

From the balanced equation above,

73 g of HCl reacted to produced 127 g of FeCl₂.

Finally, we shall determine the mass of FeCl₂ produced by the reaction of 21.6 g of HCl. This can be obtained as follow:

From the balanced equation above,

73 g of HCl reacted to produced 127 g of FeCl₂.

Therefore, 21.6 g of HCl will react to produce = (21.6 × 127)/73 = 37.58 g of FeCl₂.

Thus, 37.58 g of FeCl₂ were obtained from the reaction.

Explanation:

The nitro group is characterized by being a very strong inhibitor. Nitrobenzene nitration is checked at a reaction rate that is 10 times lower than that of benzene. The nitro group is characterized by being a goal counselor. The chemical reaction of nitrobenzene nitration with nitric and sulfuric acids, 93% of the substitution is verified in the target position.
