Answer:
-1043,8 KJ
Explanation:
Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.
Successes in your homework!
Answer: here is a description of what they look like since I cannot see the diagram.
Mitochondria- wavy line
Ribosomes- little dots
Chromosome- X
Nucleus- Circle with bite taken out of it
Endoplasm- Bubble
Nuclear membrane- Outer layer/bubble
Golgi-wavy circle thing
Vacuole- Bigger circle (but not nucleus)
Cytoplasm- its the jelly on the inside
Cell wall- only in plant cells, looks like a box
Cell membrane- The outmost part of the animal cell, the barrier.
I sure hope this helps!!!
Answer:
The answer to your question is 52.35 g of O₂
Explanation:
mass of oxygen = ?
mass of KClO₃ = 66.8 g
Chemical balanced reaction
KClO₃ ⇒ 2 KCl + 3O₂
Process
1.- Calculate the molar mass of KClO₃ and Oxygen
KClO₃ = 39 + 35.5 + (16 x 3) = 122.5 g
O₂ = 16 x 6 = 96 g
2.- Write proportions to solve this problem
122.5 g of KClO₃ ----------------- 96 g of O₂
66.8 g ----------------- x
x = (66.8 x 96) / 122.5
x = 6412.8/122.5
x = 52.35 g of O₂
Answer:
C. Digestion is the answer.
Reducing agent is an compound/atom, that loses an electron and is oxidized.
0.........+I.............+II............0
Ca + 2HCl ----> CaCl₂ + H₂
Calcium is oxidized --- it's reducing agent (reductant).
Hydrogen is reduced --- HCl is oxidizing agent.
