Answer:
83.20 g of Na3PO4
Explanation:
1 mole of Na3PO4 contains 3 moles of Na+.
Mole of Na ion to be prepared = Molarity x volume
= 0.700 x 725/1000
= 0.5075 mole
If 1 mole of Na3PO4 contains 3 moles of Na ion, then 0.5075 Na ion will be contained in:
0.5075/3 x 1 = 0.1692 mole of Na3PO4
mole of Na3PO4 = mass/molar mass = 0.1692
Hence, mass of Na3PO4 = 0.1692 x molar mass
= 0.1692 x 163.94
= 83.20 g.
83.20 g of Na3PO4 will be needed.
Answer:
Plants and animals are pH sensitive. The growth of plants is dependent on the nature of the soil. If the pH of the soil is greater than 7 and is alkaline, then the plants cannot grow in the soil.
Explanation:
<span>A flashlight is an electric-powered light source; the light source is a light bulb or an LED. The electrical energy is converted into visible light. Flashlights can be hand-held or mounted to a platform. Light from a lighting, on the other hand, is formed by exciting electrons to a higher state. </span>
The type of energy which is present between the repulsion interaction is the highest potential energy.
<h3>What is potential energy?</h3>
Potential energy is the amount of energy that is possess by any body with respect to the electric charge posses in that and other factors also.
- When molecules have a high attraction force then they have the low potential energy in them.
- When molecules have a great repulsion between them then they have the great potential energy in them.
- And molecules have the middle amount of potential energy then they have the balanced interaction.
Hence, molecules in which repulsion interaction is present will have highest potential energy.
