Hello there!
I am not really sure which part you are talking about but let me answer some of them.
First, you need to read the information they gave you about glucose etc..
13- What is produced in photosynthesis?
"Photosynthesis is essential for all life on earth, because it provides food and oxygen."
Thus, the answer is: Photosynthesis produced food and oxygen.
14- What is the glucose used for?
"The glucose produced is used by the plant for energy and growth."
Thus, the answer is: The glucose used for energy and growth of the plants.
15- What is the oxygen used for?
"The oxygen produced is released into the air for us to breath."
Thus, the answer is: The oxygen used for us to breath.
I hope this helps!
Let me know if you have questions about the answer.
Agree with the statement like most of human achievements chemistry has been used as well as misused.
Science help in development of culture and promoting human civilization but human misused this achievements in their self interest. Like innovation of nuclear power system helps in increasing nation's development but at the same time man is misusing this atomic energy for making powerful bomb.
Explanation:
Human achieved their success in various field with the help of science and technology. Every aspects of things has two side. Its depend upon us which one we will take off. Specifically chemistry the hard core science contributes a lot in upgrading civilization like innovation of nuclear power system which can reduce the use of other conventional energy resources which is much needed for our future generation.
But our so called society and civilization use this technological and scientific achievements in a negative way and produce nuclear bomb to fulfill their self interest.
Answer:
1. CrCl₃ 2. MnO₂ 3. MgCO₃
Explanation:
For a compound to be neutral, we need the same number of positive charges and negative charges.
1. Cr³⁺ ions and Cl⁻ ions. We will need 1 Cr³⁺ cation and 3 Cl⁻ anions. The chemical formula is CrCl₃.
2. Mn⁴⁺ ions and O²⁻ ions. We will need 1 Mn⁴⁺ cation and 2 O²⁻ anions. The chemical formula is MnO₂.
3. Mg²⁺ ions and CO₃²⁻ ions. We will need 1 Mg²⁺ cation and 1 CO₃²⁻ anion The chemical formula is MgCO₃.
