I'm horrible at Chem plse help! Determine whether the reaction given below would be spontaneous or not. JUSTIFY your answer.
Mg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s)
Thank you
Answer:
This is a not a spontaneous reaction.
Explanation:
No, it would not be one because if you add the reactants the products would have to be the same (same types of atoms. number of atoms, and the arrangement of the atoms). In this case the reactants and the products are not equal.
4. Which elements have a completely full outermost energy level?
Answer:
Helium (He), neon (Ne), and argon (Ar), as group 18 elements, have outer electron shells that are full or satisfy the octet rule. This makes them highly stable as single atoms. Because of their non-reactivity, they are called the inert gases or noble gases.

H2O
Answer:
Na(Sodium) and C(Carbon) only
Answer:
Na, C
Explanation:
1. KCl, or potassium chloride, is a combination of two elements- so it's a chemical compound.
2. Na, or sodium, can be found on the periodic table of elements. Therefore, it is an element.
3. C, or carbon, can also be found on the periodic table of elements. Therefore, it is an element.
4. H20, or water, is a combination of 2 hydrogen atoms that bonded into an oxygen atom. Combination of 2 or more elements is a chemical compound.
Therefore, the answers are Na and C.

Why do we fill balloons
with helium gas instead
of oxygen gas?
Answer:
Helium is less dense. Because helium is lighter than air, a helium balloon rises, just as an air bubble rises in more dense water
Explanation:
Also why not. It just is.
Answer:
This is due to the fact that helium has a lower density. A helium balloon rises like an air bubble in more dense water because helium is lighter than air. Another gas lighter than air is hydrogen, which is even lighter than helium.

Explain why oxygen relights a glowing splint?
Answer:
Oxygen gas relighting a glowing splint. The oxygen gas is produced by the decomposition of hydrogen peroxide, which is squirted into a test tube containing the decomposition catalyst manganese (IV) oxide. When the glowing splint is introduced to the test tube, it bursts back into flame when it contacts the oxygen.
Explanation:
hope its help
Oxygen relights a glowing splint due to its role as a strong oxidizer. When a glowing splint is inserted into an environment containing oxygen, it triggers a rapid combustion reaction.
Oxygen readily reacts with the fuel source on the splint (typically carbon compounds), providing the necessary oxygen molecules for the combustion process.
This exothermic reaction releases heat and light energy, causing the splint to re-ignite.
Oxygen's ability to support combustion is vital for many natural processes and industrial applications, as it enables the release of energy stored in various substances, highlighting its importance in sustaining life and various chemical reactions.

What element is being reduced in the following redox reaction? Cr(OH)4-(aq) ClO-(aq) → CrO42-(aq) Cl-(aq).
The element that is being reduced in the given redox reaction is Cl (Chlorine)
The given redox reaction is
Cr(OH)₄⁻(aq) + ClO⁻(aq) → CrO₄²⁻(aq) + Cl⁻(aq)
First, we will define the terms oxidation and reduction
Oxidation can be defined as an increase in oxidation number
Reduction is defined as a decrease in oxidation number
This means the element that is being reduced in the reaction would have a decrease in oxidation number.
Oxidation number of Cr in Cr(OH)₄⁻ is +3; and the oxidation number of Cr in CrO₄²⁻ is +6. This is an increase in oxidation number and it means Cr is being oxidized.
Oxidation number of Cl in ClO⁻ is +1; and the oxidation number of Cl in Cl⁻ is -1. This is a decrease in oxidation number and it means Cl is being reduced.
Hence, the element that is being reduced in the given redox reaction is Cl (Chlorine).

What mass of aluminium is needed to react with 640g of iron oxide
Answer:
13.5g
Explanation:
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 138.8g of aluminium is needed to react with 640g of iron oxide.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically, the balanced equation can be written as
3Fe[tex]_2[/tex]O[tex]_3[/tex] + 4Al [tex]\rightarrow[/tex] Al[tex]_2[/tex]O[tex]_3[/tex] + 6Fe
number of moles of iron oxide= 640/159.6
=4.01
number of moles of aluminium =(4/3)×4.01
=5.34moles
mass of aluminium =5.34×26
=138.8g
Therefore, 138.8g of aluminium is needed to react with 640g of iron oxide.

A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, how many moles of Gas B are present?
A flower vase placed on the table
Explanation:
A laborer pushing a crate on the table
A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, no. of moles of Gas B are 1.376.
What is combined gas law?The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.
It is a mathematical expression that relates Pressure, Volume and Temperature.
(P1 × V1)÷T1 = (P2 × V2)÷T2
We can also use the following relation-
PV = nRT
Let n be the total no. of moles.
Given,
P = 7 atm
R = 0.0821
T = 333K
V = 16 L
n = PV / RT
n = 4.096
n = no. of moles of A gas + no. of moles of gas B
4.096 = 2.72 + x
x = 1.376
Therefore, A 16.0 L container at 333 K holds a mixture of two gases with a total pressure of 7 atm. If there are 2.72 mol of Gas A in the mixture, no. of moles of Gas B are 1.376.
