Answer: Binary Fission

Explanation:

The mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.

The molar mass of a substance is the mass of 1 mole of the substance.

The molar mass of uranium is 238 g.

This is the mass of 1 mole of uranium.

The mass of 2.0 x 10-5 moles of uranium = 238 g × 2.0 x 10-5

The mass of 2.0 x 10-5 moles of uranium = 0.00476 g = 4.8 x 10-3 grams

Therefore, the mass of 2.0 x 10-5 moles of uranium is 4.8 x 10-3 grams.

AS> 0 mean the system has become more random. This means that there is increase in entropy.

Entropy, in the realm of thermodynamics, quantifies the level of chaos or unpredictability within a system. A system characterized by heightened entropy exhibits greater disorder, whereas a system marked by diminished entropy reflects a higher degree of organization.

When AS > 0, it signifies an increase in the entropy of the system. This denotes a shift toward increased disorder or randomness within the system.

Answer:

1) Without our atmosphere we wouldn't have life! The atmosphere protects our earth from letting harmful substances or rocks into our planet, which could cause damage.

2) You interact with the atmosphere in both good ways and bad. You interact by putting up things like flowers and trees, but in bad ways by releasing bad things (like carbon dioxide) and by light pollution!

3) The factors that can affect climate of an area, by latitude and longitude!

Answer:

the mass of the new copper roof will increase over time as it turns green

Explanation:

this is because copper will react with atmospheric substances to form copper compound. this does not violate the law of conversation of mass because the mass increases as copper react with atmospheric substances in the presence of atmospheric air, oxidizes to copper compounds which are heavier in mass than copper atoms

According to the law of conservation of mass, the mass of the copper roof increases as oxygen is added to it to form copper oxide.

Oxidation is a reaction in which oxygen is added to an element.

Oxidation metals in the presence of air occurs frequently as metals are reactive.

Copper roof turns green with time as the metals react with oxygen in air to form copper oxide.

The mass of the new copper roof increases in accordance with the law of conservation of mass as oxygen is added to metallic copper to increase it's mass.

Explanation:

Consider this balanced chemical equation:

2 H2 + O2 → 2 H2O

We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:

100 H2 + 50 O2 → 100 H2O

This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:

5,000 H2 + 2,500 O2 → 5,000 H2O

Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:

12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O

These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?

2 H2 + O2 → 2 H2O

is the same balanced chemical equation we started with! What this means is that chemical equations are not just balanced in terms of molecules; they are also balanced in terms of moles. We can just as easily read this chemical equation as “two moles of hydrogen react with one mole of oxygen to make two moles of water.” All balanced chemical reactions are balanced in terms of moles.

Answer:

The final volume of the balloon is 24.480 liters.

Explanation:

Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:

[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)

Where:

[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.

[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.

If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:

[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]

[tex]V_{f} = 24.480\,L[/tex]

The final volume of the balloon is 24.480 liters.

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.

Answer:

The answer is no!

Acidic oxides, or acid anhydride, are oxides that react with water to form an acid, or with a base to form a salt. They are oxides of either nonmetals or of metals in high oxidation states.

The higher animals in the food chain would probably not survive.

Answer:

Melting ice causes more warming.

Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.

Answer:

6.63 grams of CO₂ can be produced.

Explanation:

1 mol of C₃H₈ reacts to 5 moles of oxygen, in a combustion reaction in order to produce 3 moles of carbon dioxide and 4 moles of water.

First of all, we need to know, the limiting reactant:

5.52 g . 1mol / 44g = 0.125 moles of C₃H₈

8.03 g . 1mol/ 32g = 0.251 moles of oxygen.

1 mol of C₃H₈ can react to 5 moles of O₂

Then, 0.125 moles, must react to (0.125 . 5) /1 = 0.625 moles.

We only have 0.251 moles of O₂ and we need 0.625 moles. Cause we do not have enough oxygen, that's the limiting reagent.

5 moles of oxygen can produce 3 moles of CO₂

0.251 moles may produce (0.251 . 3) /5 = 0.1506 moles.

We convert the moles to mass : 0.1506 mol . 44g /mol = 6.63 g

Reaction is: C₃H₈  +  5O₂ →  3CO₂  + 4H₂O
