Water can be formed from the synthesis reaction of hydrogen with oxygen:

2 H2 (g) + O2 (g) → 2 H2O (g)

The complete reaction of 5.12 Liters of O2 with excess hydrogen produces how many moles of H2O?

A) 10.24 moles H2O
B) 114.7 moles H2O
C) 0.457 moles H2O
D) 5.12 moles H2O

Answers

Answer 1

Answer:

Explanation:

[2ΔSf(H2O (g))] - [2ΔSf(H2 (g)) + 1ΔSf(O2 (g))]

[2(188.72)] - [2(130.59) + 1(205.03)] = -88.77 J/

You want to build a house in an area with a maximum amount of species diversity. For building the house you have to clear up to 3/4th of the forest cover. How do you think this will affect the water runoff?

Answers

Answer:

The runoff will increases.

Explanation:

The runoff will be adversely affected if the 3/4th of the forest cover is removed because forest cover lowers the intensity of runoff by absorbing most of the water. The construction of house will increase the runoff due to little vegetative cover for the absorption of water and more water will runoff on the surface that will leads to flood condition in the lower elevated region of that area. The vegetative cover of the forest helps in preventing the flood condition by absorbing the runoff water.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.

Answers

Answer:

From the given Options, Option  C is correct.

the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression

Explanation:

The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.

The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option  C.

Fruiting Bodies of Fungi The recognizable forms of fungal reproductive bodies, or fruiting bodies, encountered in nature vary structurally. Common forms of fungal fruiting bodies include trumpet, club fungus, bracket, cup fungus, gill fungus, bolete, puff ball, and stinkhorn. Close observation of fruiting body anatomy can lend clues during identification of a species. Differing species of fungi can appear similar, and it is never advised to eat a wild mushroom because poisonous varieties can resemble edible ones.
1. Fungal fruiting bodies, or reproductive bodies, have different structural forms.
a. true
b. false
2. Many experiments require student-supplied items, such as _____.

Answers

Answer to Question 1:

True

Explanation

As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.

Question 2:

Many experiments require student-supplied items, such as _____.

1. Chicken

2. Fresh flowers

3. Distilled water

4. All of the Above.

Answer to Question 2:

The correct answer is 3.

Explanation

Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.

Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.

Answers

Answer:

I think its b. Competition would increase. Wildfire would increase the scarcity of resources, causing individuals to compete at higher rates.

Explanation:

not 100% sure tho

Wildfires can immediately impact competition in a forest ecosystem because wildfires would increase resource scarcity, causing individuals to compete at higher rates.

What are the consequences of forest fires?

In addition to destroying native vegetation and killing many wild animals, a forest fire can also cause serious financial damage and even endanger the lives of people and domestic animals.

With this information, we can conclude that wildfires can immediately affect competition in a forest ecosystem because wildfires would increase resource scarcity, causing individuals to compete at higher rates.
