I think it may be “past climate of Earth seen in glaciers”/ I learned about this and that one doesn’t really ring a bell, plus it doesn’t make sense to me. I four sure know it’s not the fitting like a puzzle one. Sorry if I get this wrong.
Answer:
[H₂] = 1.61x10⁻³ M
Explanation:
2H₂S(g) ⇋ 2H₂(g) + S₂(g)
Kc = 9.30x10⁻⁸ = ![\frac{[H_{2}]^2[S_{2}]}{[H_{2}S]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH_%7B2%7D%5D%5E2%5BS_%7B2%7D%5D%7D%7B%5BH_%7B2%7DS%5D%5E2%7D)
First we <u>calculate the initial concentration</u>:
0.45 molH₂S / 3.0L = 0.15 M
The concentrations at equilibrium would be:
[H₂S] = 0.15 - 2x
[H₂] = 2x
[S₂] = x
We <u>put the data in the Kc expression and solve for x</u>:
We make a simplification because x<<< 0.0225:
x = 8.058x10⁻⁴
[H₂] = 2*x = 1.61x10⁻³ M
Answer:
Flammability is a material’s ability to burn in the presence of <u><em>oxygen.</em></u>
Explanation:
Flammability can be described as the ability of a substance to get ignited. Flammability will lead to fire or combustion. Some substances are highly flammable like Benzene. Other tend to be just flammable. And there are also compounds which will nor be flammable at all as they won't react with oxygen. Examples of these substances include helium, steel or glass.
The flammability of a substance shall be considered a very important aspect when storing or transporting a substance.
Answer:
Hi
Inbreeding increases the chances of transmission to the next generation of types of inherited diseases. Our genome is made up of two copies of each gene, one inherited from our father and one from our mother. In order for autosomal recessive diseases to be found, the two copies of the gene need to be mutated. If only one of the copies is mutated and the other is not, the person is a carrier but does not manifest any of the clinical symptoms of the disease. One of these diseases is hemophilia. An example of this is Prince Leopold, he was the first real member affected by hemophilia, in this case hemophilia B. When one of the proteins necessary for blood clotting is missing, the wounds take much longer to heal. Small cuts are not usually a problem, but major injuries can cause bleeding.
The defective gene in people who suffer from this type of hemophilia is called F9, and it is located on the X chromosome. That means it has an inheritance linked to sex. Women have two X chromosomes (XX), while men have an X chromosome and one Y (XY). Since hemophilia alleles are recessive, two defective alleles are needed in women to suffer from the disease, while only one is needed in men. Therefore, the disease is much more common in men. The most frequent hemophilia is that of type A and is due to a defect in coagulation factor VIII, whose gene also has an inheritance linked to sex.
Explanation:
Bitter taste, high pH, and caustic Bitter are the characteristics of base.
<h3>What are the characteristics of base?</h3>
Bases have bitter taste, soapy feel, turn red litmus paper blue. Bases are substances that contain metal oxides or hydroxides. Its pH is higher than 7 up to 14.
So we can conclude that bitter taste, high pH, and caustic Bitter are the characteristics of base.
