Why are alkali metals more reactive than alkaline earth metals?

1 answer:

5 0

A: It takes more energy to remove two valence electrons from an atom than one valence electron. This makes alkaline Earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.

The light reactions of photosynthesis use _____ and produce _____. The light reactions of photosynthesis use _____ and produce _

SashulF [63]

<h2>Input = $NADP^+$ , water and Output = $NADPH + O_2$ </h2>

Explanation:

The light reactions of photosynthesis use water and produce Oxygen, NADPH.

The equation for photosynthesis :

$6 CO_2 + 6 H_2O$ → $C_6H_12O_6 + 6 O_2$

The process of photosynthesis in two stages -

The first stage is called the light reaction in which the light energy from the sun is captured and converted into chemical energy stored in the form of ATP and NADPH

The second stage is the process of conversion of ATP molecules to sugar or glucose (the Calvin Cycle)

For a light reaction -

Net Input is of, $NADP^+$ , $Light, Water, ADP$

Net Output is of, $ATP, NADPH, O_2$

Give the structures of both 1,2 and 1,4 adducts resulting from reaction of 1 equivalent of hcl with 1,3-pentadiene

GrogVix [38]

1,3-pentadiene has two double bonds which are conjugated, which undergo electrophilic addition reaction on reacting with $HCl$ .

The structure of 1,3-pentadiene is shown in the image.

When strong acid such as $HCl$ reacts with 1,3-pentadiene, the electrophilic addition reaction can occur either on double bond at 1,2-position or at 3,4-position. The reaction that occurs is shown in the image.
