Which two parts are needed to make a neutral atom of nitrogen A. Electron clouds with a total of 14 electrons B. Electron cloud is a total of seven electrons C. A nucleus with seven protons and seven neutrons D. A nucleus with three protons and four neutrons

Answers

Answer:

B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons

Explanation:

An atom is consist of three subatomic particles: electron, proton, and neutron. Proton are positively charged particles and neutron have neutral charge, they both are present inside the nucleus in the center of the atom whereas electrons are negatively charged and surround the nucleus in a definite orbit.

Nitrogen is an element with 7 electrons in its outer orbit. As electrons are negatively charged so nitrogen atom will require 7 protons inside the nucleus to form a neutral atom of nitrogen. So, A neutral atom of nitrogen will consist of 7 electrons and 7 protons.

As, neutron has neutral charge so it will not affect the composition of neutral atom of nitrogen.

Hence, the correct options are:

"B. Electron cloud is a total of seven electrons

C. A nucleus with seven protons and seven neutrons ".

If 4.7 moles of oxygen gas are allowed to react with 3.9 moles of iron according to the following equation:
4 Fe + 3 O2 → 2 Fe2O
How many moles of Fe2O3 can be formed?​

Answers

Moles of Fe₂O₃ formed : 1.95

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

[tex]\tt 4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]

We find the limiting reactant from the ratio of the mole and the reaction coefficient

Fe ⇒ 3.9 : 4 = 0.975

O ⇒ 4.7 : 3 = 1.56

Because the ratio of Fe is smaller, then Fe becomes the limiting reactant

Reaction

4Fe + 3O₂ ⇒ 2Fe₂O₃

mol Fe₂O₃ from mol of Fe as limiting reactant

mol ratio Fe₂O₃ : Fe = 2 : 4, then mol Fe₂O₃ :

[tex]\tt =\dfrac{2}{4}\times 3.9=\boxed{\bold{1.95}}[/tex]

Chelsea adds a 65% acid solution to 25 milliliters of a solution that is 30% acid. How much of the 65%
acid solution should be added to create a solution that is 40% acid?

Answers

Answer:

10 ml

Explanation:

The concentration of the acid solution Chelsea adds to the 25 milliliters of 30% acid solution = 65%

The concentration of the acid solution Chelsea requires = 40%

The volume, X, of the 65% acid solution required is given as follows;

65% × X + 30% × 25 = 40% × (25 + X)

As fractions, we have;

0.65 × X + 0.3 × 25 = 0.4 × (25 + X)

0.65·X + 7.5 = 10 + 0.4·X

0.65·X  - 0.4·X = 10 - 7.5

0.25·X = 2.5

X = 2.5/0.25 = 10

X = 10 ml

The volume of the 65% acid that should be added to create a solution that is 40% acid = 10 ml.

of aluminum?
0 2.66667g/ml
O 2.67 g/mL
O 2.667g/mL
O 2.7 g/mL

Answers

Answer:

The answer is 2.7 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 12 g

volume = final volume of water - initial volume of water

volume = 18.5 - 14 = 4.5 mL

So we have

[tex]density = \frac{12}{4.5} \\ = 2.66666666...[/tex]

We have the final answer as

2.70 g/mL

A hiker tries to prepare a hard-boiled egg on the high slopes of Mount Everest. The base camp is located 5,300 meters above sea level. The hiker observes that the water begins to boil at 82⁰C, much lower than the 100⁰C needed to cook the raw egg. He hopes that just leaving the egg in the boiling water longer will let the egg cook. Will he have hard-boiled eggs for breakfast?

Answers

Answer:

He will not have hard-boiled eggs for breakfast

Explanation:

The given parameters are;

The elevation at which the base camp of the hiker is located = 5,300 meters

The boiling point of water at the elevation of the base camp = 82°C

The temperature required to cook the raw egg = 100°C

Therefore, we have;

The temperature of the boiling water at the given elevation of the base camp 82°C < The temperature required to cook the raw egg 100°C

Therefore, the eggs will not be hard boiled.

The hiker won't have hard-boiled eggs for breakfast as a result of the

boiling point of water being less than 100⁰C.

The boiling point decreases with an increase in altitude. The hiker was at

5,300 meters above sea level which made the boiling point of water to be

decreased to 82⁰C.

Since the water isn't able to achieve the boiling point of 100⁰C, then the raw

egg won't be hard boiled for breakfast.

How many atoms of aluminum (Al) are contained in 3.73 moles of alumni

Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?

Answers

Answer:

Explanation:

As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.

However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.

Please note this isn't a scientific fact and just a possibility as requested in the question.

PLZ ANSWER 100 POINTShere is the passage to help u a bit Colony Collapse Disorder In 2006, beekeepers throughout the United States began to notice something newand troubling. Adult honeybees, known as worker bees, were disappearing from their hives, seemingly abandoning them. Few or no dead bees were found in the hives, while the queen and larvae were alive and well but without the swarm of worker bees that typically attended them to keep them alive. What had happened? The phenomenon became so widespread that it soon received a name, Colony Collapse Disorder (CCD) . There was no denying that CCD was a problem; after all, American agriculture depends on the work of honeybees and other pollinators. At least three-quarters of the crops grown in the United States depend on honeybee pollination for their survival. These include such staples as strawberries, blueberries, apples, broccoli, asparagus, and almonds. Without them, both farmers and anyone who enjoys fresh fruits and vegetables will suffer. But what is causing this problem? Scientists have rigorously studied a variety of possible causes, ranging from genetically modified crops to climate change to cell phone towers. Sadly, nothing has shown to be the cause of the problem. The most likely culprits are pathogens, or disease-causing organisms. These have been found in larger numbers in colonies affected by CCD than in those unaffected. But these pathogens have included various viruses and bacteria, some found in greater concentrations in different parts of the country. If CCD is caused by a single disease, identifying that disease will be difficult. The CCD epidemic is most likely the result of multiple causespathogens, poor nutrition, pesticides, lack of genetic diversity, and habitat loss. Efforts to prevent colony loss have been mildly successful. The number lost has declined each year since 2008. But until a solution to this problem is found, CCD will remain a concern that will threaten not only the future of bees, but also of the people who rely on the food that they help produce.these are the questions Which inference can be made about the cause of CCD in Colony Collapse Disorder?It is a threat that needs to be identified as soon as possible.It will impact humans and affect their health in the future.It is very complex and will be challenging to overcome.It affects bees most seriously but threatens other pollinators also.Question 2Part BWhich statement from "Colony Collapse Disorder" best supports the answer in Part A?Without [honeybees], both farmers and anyone who enjoys fresh fruits and vegetables will suffer.Scientists rigorously studied a variety of possible causes, ranging from genetically modified crops to climate change to cell phone towers.The CCD epidemic is most likely the result of multiple causespathogens, poor nutrition, pesticides, lack of genetic diversity, and habitat loss.The most likely culprits are pathogens, or disease-causing organisms.
