Answer: option C - The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell
Explanation:
Meiosis is also known as REDUCTIVE DIVISION, simply because a parent cell with diploid number of chromosome (46) is divided into four daughter cells with haploid number of chromosome (23)
Thus, ONLY option C correctly defines meiosis
Answer:
The answer to your question is limiting reactant = Fe
Explanation:
Data
moles of Fe = 2
moles of O₂ = 6
Process
1.- Write the balanced chemical reaction
Fe + O₂ ⇒ Fe₂O₃
Reactants Elements Products
1 Fe 2
2 O 3
4Fe + 3O₂ ⇒ 2Fe₂O₃
Reactants Elements Products
4 Fe 4
6 O 6
2.- Use the balanced chemical reaction to determine the limiting reactant.
Theoretical proportion of reactants 4 moles Fe / 3 moles O₂ = 1.33
Experimental proportion of reactants = 2 moles Fe/6 moles O₂ = 0.333
3.- Conclusion
As the experimental proportion was lower than the theoretical we conclude that the amount of Fe was lower in the experiment which is the limiting reactant.
Answer b I think so sorry if not is
Answer:
It is illegal
Explanation:
Fracking involves drilling deep into the earth crust in which a water mixture with high pressure is directed at the rock with the purpose of releasing the gas inside. This process is common in the exploration of natural gas and other hydrocarbons.
It is however illegal because the water are mostly contaminated due to the hydrocarbons present and harmful to life. It is advisable and the best to remove the water and recycle them in treatment plants
Answer:
[NaCl] = 1.72 M
Explanation:
First of all, we balance the equation:
BaCl₂ + Na₂SO₄ → 2NaCl + BaSO₄
We convert mass of barium chloride to moles
45 g . 1mol / 208.23g = 0.216 moles
Ratio is 1:2. This means, that our moles of reactant may produce the double of moles, of product.
0.216 . 2 = 0.432 moles of NaCl are been produced.
Molarity is mol/L. We convert volume of water from mL to L
250 mL . 1L /1000 mL = 0.250 L
[NaCl] = 0.432 mol/0.250L = 1.72 M
