Answer:

The correct answer is number 2. Elliptical, Spiral, Irregular.

Explanation:

Unfortunately, you did not attach the passage. Without the passage, we do not know what its content is.

So we are going to answer this question with our own knowledge.

The types of galaxies by their ability to form new stars, from most to least activity are "Elliptical, Spiral, Irregular."

That is the way astronomers classify galaxies in scientific terms. These scientists consider that the smallest galaxies or dwarf galaxies have approximately 100 million stars. On the other hand, giant galaxies have billions or trillions of stars. That immense is our universe.

Scientists still studying the universe and the galaxies to understand the way galaxies are formed.

Answer:

B. 20m/s

Explanation:

The wavelength of a wave can be calculated using the formula;

λ = v/f

Where;

λ = wavelength (m)

v = velocity (m/s)

f = frequency (Hz)

According to the information provided in this question; the wave has a wavelength (λ) of 2m and a frequency (f) of 10Hz.

Using λ = v/f

v = λ × f

v = 2 × 10

v = 20m/s.

Answer:

ΔHr = -566kJ/mol

Explanation:

Based on Hess's law, the ΔH of a reaction is the sum of the ΔH's of products times its coefficient subtracting the ΔH of reactants. For the reaction:

2CO(g) + O2(g) → 2CO2(g)

ΔH is:

ΔHr = 2*ΔH CO2 - (2ΔH CO + ΔH O2)

As ΔH CO2 = -393.5kJ/mol; ΔH CO = -110.5kJ/mol and ΔH O2 = 0kJ/mol

ΔHr =  2*-393.5kJ/mol - (2*-110.5kJ/mol)

Answer:

Element X is Cs or cesium

Answer: The answer is YES. There would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use.

Explanation:

Carbon is an element in the periodic table with the atomic number of 12. It has 4 electrons on its outermost shell in the electronic configuration. These are valence electrons which are used to form bonds in a wide range of both organic and inorganic compounds, giving rise to simply molecules like carbondioxide.

CARBON CYCLE is a natural process through which carbon and it's compounds are kept fairly constant through recycling. They are found in fossils fuels such as oil, coal, and natural gas. When these fossil fuels are burnt and used as energy, carbon is released in form of carbondioxide. This is just one of the ways carbon is returned to the atmosphere. Other ways include:

--> respiration of plants and animals

--> decomposition of organic substances

--> action of dilute acids and heat on trioxocarbonates (V) and hydrogen trioxocarbonates (IV).

Carbon is then removed from the atmosphere through:

--> plants in photosynthesis

--> rain water as weak trioxocarbonate (IV) acid.

Therefore, there would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use because the burning of fossil fuels is not the only way carbon is returned to the atmosphere during carbon cycle.

Answer:

Hi ,

Answer :

Sulfuric acid

Answer:

b)6.2 grams

Explanation:

Recall that percentage yield =

actual yield/theoretical yield * 100/1

theoretical yield = 8.2 grams

percentage yield = 75%

Let the actual yield be x

Hence;

75 = x/8.2 * 100

75 = 100x/8.2

75 * 8.2 = 100x

x = 75 * 8.2/100

x = 6.15 g

x = 6.2 g

B: There are only so many ways matter can arrange itself within that infinite universe.

The idea of a parallel universe was supported by Brian Greene on the basis that there are only so many ways matter can arrange itself within that infinite universe.

Matter is anything that has mass and occupy space. The universe as we know it is filled with matter. The theory of multiple universe holds that there could be another universe apart from this one that we know.

This theory was supported by Brian Greene on the basis that there are only so many ways matter can arrange itself within that infinite universe.

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

Answer:

0.15

Explanation:

The partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.

Dalton's law can be described as the total pressure of all gases exerted being equal to the sum of the partial pressures of every gas in the mixture of non-reacting gases.

The total pressure of  a gas mixture of gases can mathematically be defined as :

P (total) = P₁ + P₂ + P₃ + ......

Given, the total pressure of a gas mixture = Ptotal = 1.05 atm

The fraction of carbon dioxide in the mixture = 55 % = 0.55

The fraction of nitrogen in the mixture = 31 % = 0.31

The partial pressure of  carbon dioxide in the mixture can be calculated as:

P(CO₂) = 0.55× P(total)

P(CO₂) = 0.55× 1.05

P(CO₂) = 0.58 atm

Therefore, the partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.

Answer:

3.02 X1023 atoms Ag limol. - - 0.50 1 moles. 6.02241023 atoms.

Molar mass is the amount grams that one mole weighs.

Explanation: You need to find the molar mass of NaCl which is the same as the amu on the periodic table in grams. So it is 22.99(Na) + 35.45(Cl) = 58.44

You also know that for every mole of NaCl you have 1 mole of Na because every molecule of NaCl has 1 atom of Na.

Finally, using the periodic table, again, you see that the molar mass of Na is 22.99.

Then using stoichiometry, you can find the grams of sodium.

100(g NaCl) * 1 mol (NaCl)/58.44 g (NaCl) * 1 mol (Na)/ 1 mol (NaCl) * 22.99 (g of Na)/ 1 mol (Na)

which equals 39.339435 g of Na.

If you need to maintain significant figures the answer will be 40.

Answer: it is D

Explanation:

Scientists can model the effects of reactant concentration on the speed of a reaction With an atomic model. Hence, D is correct.

Atomic model, in physics, a model used to describe the structure and makeup of an atom. Atomic models have gone through many changes over time, evolving as necessary to fit experimental data. For a more in-depth discussion of the history of atomic models, see atom: development of atomic theory.

Scientists use models to study atoms because atoms are extremely small and can't even be seen. If atoms can't be seen, it's easier to study and predict what atoms will do with a representation of them.

Models are useful tools in learning science which can be used to improve explanations, generate discussion, make predictions, provide visual representations of abstract concepts and generate mental models.

Therefore, Scientists can model the effects of reactant concentration on the speed of a reaction With an atomic model. Hence, D is correct.
