mel-nik [20]3 years ago
7 0

If 14 grams of hydrogen reacted with 24.7 grams of oxygen 27.7875 grams of water will be formed.

Explanation:

2H2+O2----------->2H2O.

  • From the above equation, we can say that 4g of Hydrogen will react with 32 g of oxygen.
  • In this question, Hydrogen is in excess amount.
  • 32 g of Oxygen will react with = 4 g of H2.
  • Therefore 24.7g of Oxygen will react with =24.7x4/32= 3.0875 g H2.  
  • The remaining 10.9125g of H2 will be left unreacted.
  • Therefore the amount of water formed=(24.7+3.0875)=27.7875 g

Which type of carbon fixation stores carbon dioxide in acid form? a. c3 b. c4 c. cam d. all of the above
Luba_88 [7]

The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.

<h3>What are CAM?</h3>

CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.

In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.

Hence option (C) is correct.

What determines a molecules VSEPR shape?
frosja888 [35]
Using the VSEPR theory, the electron bond pairs and lone pairs on the center atom will help us predict the shape of a molecule. The shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction.

What is the energy of a photon that emits a light of frequency 6.42 x 1014 Hz?<br><br>​
svetlana [45]

Answer:

Option B. 4.25×10¯¹⁹ J

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 6.42×10¹⁴ Hz

Energy (E) =?

Energy and frequency are related by the following equation:

Energy (E) = Planck's constant (h) × frequency (f)

E = hf

With the above formula, we can obtain the energy of the photon as follow:

Frequency (f) = 6.42×10¹⁴ Hz

Planck's constant (h) = 6.63×10¯³⁴ Js

Energy (E) =?

E = hf

E = 6.63×10¯³⁴ × 6.42×10¹⁴

E = 4.25×10¯¹⁹ J

Thus, the energy of the photon is 4.25×10¯¹⁹ J
