Answer: Option (b) is the correct answer.

Explanation:

Phototropism is defined as the ability of a plant to either respond to light or does not respond to light.

When a plant respond to light then it is known as positive phototropism and when a plant does not respond to light then it is known as negative phototropism.

Therefore, when a sunflower turns its head towards sunlight then it means sunflower is responding to light.

Thus, we can conclude that phototropism triggers this behavior in a sunflower.

Covalent bonds form between hydrogen and oxygen atoms in a water molecule as a result of the:
ankoles [38]
The overall attraction of this process is called hydrogen bonding in water which have very powerful bonds. These powerful bonds are known as covalent bonds and are formed when electrons are shared by atoms. 

The sharing of these electrons occur when hydrogen atoms share an electron + an oxygen atom. I hope I was able to satisfyingly answer your question. If you have any more questionings based on the information, let me know! :)

If .75 moles of ammonia is needed, how many grams of nitrogen will be consumed?
MrMuchimi

We have to get the amount of nitrogen to be consumed to get 0.75 moles of ammonia.

The amount of nitrogen (in grams) required to prepare 0.75 moles of ammonia is: 10.5 grams.

Ammonia (NH₃) can be prepared from nitrogen (N₂) as per following balanced chemical reaction-

N₂ (g) + 3H₂ (g) ⇄ 2NH₃ (g)

According to the above reaction, to prepare 2 moles of ammonia, one mole of nitrogen is required. Hence, to prepare 0.75 moles of ammonia, \frac{1 X 0.75}{2} moles = 0.375 moles of nitrogen is required.

Molar mass of nitrogen is 28 grams, i.e, mass of one mole of nitrogen is 28 grams, so mass of 0.375 moles of nitrogen is 0.375 X 28 grams=10.5 grams of nitrogen.

Therefore, the amount of nitrogen (in grams) required to prepare 0.75 moles of ammonia is 10.5 grams.

Lera25 [3.4K]

Answer:

A) The mass would be the same.

Explanation:

Since there is no loss of any particle to vapor during the phase change process from solid to liquid, the mass of the before and after the process will remain the same.

  • In this way, the law of conservation of mass is obeyed.
  • Mass is the amount of matter contained in a substance.
  • Since there is no room for escape or matter loss, the mass will remain the same.
