50% of the planets are made mainly of gas true or false
ella [17]

Answer: I think the answer is true

Explanation: If you think about it, the terrestial planets ( being  venus, earth, mars, and mercury) are made up very little gas which are carbon dioxide, nitrogen and oxygen, and the gas giants ( being jupiter, saturn, neptune, and uranus) have gases such as hydrogen and helium. Thus meaning, the terrestial planets could be a part of it and the gas giants are the most. So yes, the answer is true.

Oxygen is formed from carbon dioxide in _____(1)_____, while carbon dioxide is formed from oxygen in _____(2)_____.
g100num [7]

Answer:

Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>

Explanation:

Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP.  The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.

In our bodies, glucose is broken down into carbon dioxide and water, much like a combustion reaction. How many grams of o2 are n
Sedbober [7]

160g of O₂ will be required to fully react with 150g of glucose when glucose is broken down in our bodies to produce carbon dioxide and water.

The breakdown of glucose in our bodies can be represented by the following reaction:

C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)

As shown in the reaction, a mole of glucose reacts with 6 moles of oxygen.

To calculate the molecular mass:

1 mole of glucose (C₆H₁₂O₆) = (6x12) + (12x1) + (6x16) = 180g

6 moles of oxygen= 6x (2x16) = 192g

180g of glucose reacts with 192g of oxygen. So, to calculate the amount of oxygen required to fully react with 150g of glucose=

150 x 192/180 = 160g of oxygen.

Therefore, 160g of oxygen is required to fully react with 150g of glucose.
