What type of reaction produces a precipitate?
Pavlova-9 [17]
The correct answer is C.

Most of the time, double replacements produce one product that is soluble and one that is insoluble

This results in a precipitate within a liquid or aqueous solution

Hope this helps

Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider a mixture of six nitrogen molecules and six hydrogen molec
Nezavi [6.7K]

Answer:

a)  No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.

Explanation:

The balanced reaction between nitrogen and hydrogen molecules to give ammonia molecules is:

N_{2}(g)+3H_{2}(g) -->2NH_{3}

Thus one molecule of nitrogen will react with three molecules of hydrogen to give two molecules of ammonia.

We have six molecules of each nitrogen and hydrogen in the closed container and they undergo complete reaction it means the limiting reagent is hydrogen. For six molecules of nitrogen, eighteen molecules of hydrogen will be required.

So six molecules of hydrogen will react with two molecules of nitrogen to give four molecules of ammonia.

The product mixture will have

a) No molecules of hydrogen

b) four molecules of ammonia

c) four left molecules of nitrogen.

In a process called photosynthesis, plants use carbon dioxide and water, along with energy from sunlight, to produce sugar and o
Alex Ar [27]

24 molecules of H2O are needed by the plant to produce 4 molecules of sugar.

<h2>What is photosynthesis?</h2>

The process by which plants convert carbon dioxide, water, and sunlight into oxygen and sugar-based energy is known as photosynthesis.

<h3>The photosynthesis equation is as follows:</h3>

                   6CO2 + 6H2O + Sunlight → C6H12O6 + 6O2

The following three significant activities are involved in photosynthesis:

1. Chlorophyll absorbs light energy.

2. Water molecules are divided into hydrogen and oxygen and light energy is converted to chemical energy.

3. Carbon dioxide is converted to sugars.

         

Therefore, a plant needs four molecules of H2O and four molecules of CO2 to make one molecule of glucose or sugar, hence a plant needs 24 molecules of H2O and 24 molecules of CO2 to make four molecules of sugar.

How was the Periodic Table of Elements developed and how are the elements arranged on it?
saw5 [17]

Answer:

Following are the solution to this question:

Explanation:

Mendeleev has been the chemist that designed a periodic table for component identification based on the increasing number of elements. Thus, the is traditionally called a table parent and this periodic table had some drawbacks.

Consequently, Mosley rebuilt Mendeleev's periodic table to once again overcome this disadvantage. Which atoms were arranged as per the increasing order of atomic number instead of mass number. The traditional table, therefore, comprises seven horizontal lines regarded as cycles. But 18 control limits were named group lines.

The whole Periodical Tables is classified as a,p,d, and f block

S block, groups have 1 and 2.

P block, group has 13-18  

D block, group has 3 to 12

F block, – Two lines far below the periodic table.
