Answer:
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis
have a pH greater than 7, and turn blue-purple in universal
indicator.
Explanation:
Answer:
Order of the cycle:
Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
Explanation:
<u>Step -1:</u>
Carbon dioxide is taken in by plants during photosynthesis.
<u>Step -4;</u>
The animal eats a plant and uses its carbohydrates for energy.
<u>Step - 3</u>
The animal releases the carbon dioxide back into the atmosphere during respiration.
<u>Step -2</u>
The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Therefore, order of the cycle is Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.
Answer: Diagram 4
Explanation: Diagram 1 represents a state in which particles are closely packed , thus cannot be a representation of gas.
Diagram 2 represents a state in which particles are loosely packed , thus can be a representation of gas.
Diagram 3 represents a state in which particles are closely packed , thus can be a representation of a solid.
Diagram 4 represents a state in which particles are loosely packed , thus can be a representation of gas. It also represents the particles in ionized form. Particles are existing as ions bearing positive and negative charges.
Ph is the most important chemical soil property in terms of nutrient availability
