Producers<span>, such as a tree, make their own food. The </span>consumers, such as a giraffe, eat the energy that the producers produce since they can't make their own. The food chain is an excellent way to view this. For example, a plant produces the energy needed for it lo live, and a sheep eats form it to achieve energy since it cant produce its own. Later, a wolf eats the sheep to obtain energy for itself and so on.

Producers create their own food with photosynthesis meanwhile the consumers; carnivores(animals), herbivores(plants) and, omnivores(plants and animals) eat what their rank is.

Hydrides are compounds made up of hydrogen and metal. Why ammonia has the highest boiling point among the hydrides of elements i
RoseWind [281]
The correct option is D.
The hydrogen atoms that are attached to the nitrogen atom in the ammonia molecule are capable of forming hydrogen bond. The hydrogen bond that exist in the ammonia molecule is the reason why it shows higher boiling point compare to the other hydrides. Hydrogen bond occur in ammonia because ammonia is one of the most electronegative elements.

The pOH of a solution is 9.21. Calculate the hydrogen ion concentration of the solution. Be sure to report your answer to the co
11Alexandr11 [23.1K]

Answer:

[OH-] = 6.17 *10^-10

Explanation:

Step 1: Data given

pOH = 9.21

Step 2: Calculate [OH-]

pOH = -log [OH-] = 9.21

[OH-] = 10^-9.21

[OH-] = 6.17 *10^-10

Step 3: Check if it's correct

pOH + pH = 14

[H+]*[OH-] = 10^-14

pH = 14 - 9.21 = 4.79

[H+] = 10^-4.79

[H+] = 1.62 *10^-5

6.17 * 10^-10 * 1.62 * 10^-5 = 1* 10^-14

If a balloon is filled with a mixture of helium and oxygen, which gas will escape faster? Why?
Serjik [45]

Answer:

The rate of leakage will be higher for helium; its molecules move about 3 times faster than oxygen’s

Explanation:

Step 1: Data given

Molar mass helium = 4.0 g/mol

Molar mass O2 = 32 g/mol

Step 2: Graham's law

Graham's Law of Effusion states that the rate of effusion of a gas is inversely proportional to the square root of the molecular mass : 1/(Mr)^0.5

Rate of escape for He = 1/(4.0)^0.5 = 0.5

Rate of escape for O2 = 1/(32)^0.5 = 0.177

The rate of leakage will be higher for helium; its molecules move about 3 times faster than oxygen’s
