What is the chemical equation for photosynthesis?
1. What is the chemical equation for photosynthesis?
Sun,and Water
Sorry wrong
Jawaban:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Penjelasan:
sorry if wrong

5. Does each of the following describe a physical change or a chemical change.
Jawaban:
1. "Melting an ice cube." This describes a physical change because the ice cube is changing from a solid to a liquid, but its chemical composition is not changing.
2. "Burning a piece of paper." This describes a chemical change because the paper is reacting with oxygen to produce heat, light, and ash, which are all different substances than the original paper.
3. "Cutting an apple into slices." This describes a physical change because the apple is being physically altered (cut into slices) but its chemical composition is not changing.
4. "Mixing vinegar and baking soda." This describes a chemical change because the vinegar (an acid) and baking soda (a base) are reacting to produce carbon dioxide gas and water, which are different substances than the original vinegar and baking soda.
5. "Freezing water to make ice." This describes a physical change because the water is changing from a liquid to a solid, but its chemical composition is not changing.
6. 3 Factors that caused the unbalanced ecosystem.
Basically, the threat to the balance of this ecosystem is caused by the scarcity of animals and plants due to the following 3 factors:
-low reproductive rates,
-natural disasters,
-human activities that harm the environment.
translate:
Pada dasarnya, ancaman keseimbangan ekosistem ini disebabkan karena adanya kelangkaan hewan dan tumbuhan akibat 3 faktor berikut ini:
-tingkat reproduksi yang rendah,
-bencana alam,
-aktivitas manusia yang merugikan lingkungan.
7. balance the following chemical equations...KOH+...H3PO4=...K3PO4+H2O
3 KOH + 1 H3PO4 => 1 K3PO4 + 3 H2O
8. Write a balanced chemical equation describing the reaction of zinc and hydrochloric acid !
Answer :Reaction Metal Metal =Zn(s) Hydrochloric acid solution =HCl(aq) Zinc Chloride =ZnCl2(aq) Hydrogen Gas =H2 (g) Zn(s)+HCl (aq) -->ZnCl2(aq)+H2 (g) EquateZn(s) +2HCl(aq)-->ZnCL2 (aq) +H2 (g)
9. solve each of the following equation 30+7y=-2y-6
Jawab:
Penjelasan dengan langkah-langkah:
30+7y=-2y-6
7y + 2y = - 6 - 30
9y = -36
y = -36/9
y = -4
10. Find the value of x of absolute value in the following equation: | 4 - 3x | = | -4 |
|4 - 3x| = |-4| |4 - 3x| = 4 , , 4 - 3x = 4 -3x = 4 - 4 -3x = 0 x = 0 . . 4 - 3x = -4 -3x = - 4 - 4 -3x = -8 x = 8/3
11. Solve the following equation:2y - 7 = 7y - 27y = __
y = 4
Penjelasan dengan langkah-langkah:
2y-7 = 7y-27
2y-7y = -27+7
-5y = -20
y = 4
12. Find the value of x of the following equation. x2+(x+2)2
Jawab:
(x + 2)² = (x + 2) (x + 2)
=x.x + x.2 + x.2 + 2.2
=x² + 2x + 2x + 4
=x² + 4x + 4
x² + x² + 4x + 4=2x² + 4x + 4
