Answer:
Sulfur
Explanation:
I'm sorry I was too late!
If there is an excess of a substance in a reaction, then there is more than enough to complete the reaction. This means that, because we have a specific amount of sulfur, it has to be the limiting reagent.
A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 C. What will the volume of the balloon be if the temperature is increased to 80.0 C and the pressure remains constant? (Hint: Use the Charles law equation)
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.
can acidic oxide react with acids?
If not, why?
Answer:
no
Explanation:
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.
How many moles of O2 will react with 5.42 moles Fe?
Answer:
I hope this help you and Please mark me as Brilliant
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.

How does warmer planet causes ice to melt and then cause the warm up even more?
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.

What does AS> O mean?
AS> 0 mean the system has become more random. This means that there is increase in entropy.
What is 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:
Nuclear
Explanation:
The material most often used in nuclear power plants is the element uranium. Although uranium is found in rocks all over the world, nuclear power plants usually use a very rare type of uranium, U-235. Uranium is a non-renewable resource. ... Nuclear power plants do not pollute the air or emit greenhouse gases.
