Answer:

Group II (Second left group)

Valency = 2

More Information :

The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia, and baryta. These oxides are basic (alkaline) when combined with water.

The elements are

  • beryllium (Be)
  • magnesium (Mg)
  • calcium (Ca)
  • strontium (Sr)
  • barium (Ba)
  • radium (Ra).

How many moles of SO2 will be produced from 11.5 moles of O2?
pshichka [43]

Explanation:

Respuesta: La masa atómica del carbono (C) es 12 g/mol; para el oxígeno (O) es de 16 g/mol. Esto significa que 6.022 x 1023 átomos de carbono pesan 12 gramos. Según esto, el peso molecular del CO2 es: 12 g/mol [C] + 2 x 16 g/mol [O2] = 44 g/mol

The effect of a catalyst on an equilibrium is to ________. Select one: a. increase the rate of the forward reaction only b. slow
Georgia [21]

Answer:

E

Explanation:

A catalyst is a substance which alters the rate of a chemical reaction. We check for the correctness of each of the options as follows:

A. Is wrong.

A catalyst can increase the rate of the forward and backward reaction

B. Is wrong

A catalyst does not slow the reverse reaction only. This particular case is the case of a negative catalyst

C is wrong

A catalyst has no effect on the equilibrium nor the equilibrium constant

D is wrong

Catalyst has no effect on equilibrium value

E is correct

Although Catalysts has no effect on equilibrium or its constant value, it can increase the the rate at which equilibrium is achieved by speeding up the reaction through bringing down the activation energy

A is a d-aldohexose and B is an L-aldohexose. they afford the same optically active aldaric acid after dilute nitric acid oxidat
Alexeev081 [22]

Answer:

D-Glucose and L-Glucose

Explanation:

Aldohexose are the sugars which have six number of carbons and ends up in having an aldehyde group at one end. When dilute nitric acid is treated with any of them, the molecule gets oxidized (gets oxygen) and therefore turns into carboxylic acid.

The name of A is D-Glucose, and B is L-Glucose. Please find the structural formula attached.
