How many grams of water will form if 10.54 g H2 react with 95.10 g O2
Answers
Answer : The amount of water will be, 94.86 grams
Solution :
First we have to calculate the moles of and
.
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 1 mole of
So, 5.27 moles of react with
moles of
That means, in the given balanced reaction, is a limiting reagent because it limits the formation of products and
is an excess reagent.
The excess reagent remains = 2.97 - 2.63 = 0.34 moles
Now we have to calculate the moles of .
As, 2 moles of react with 2 moles of
So, 5.27 moles of react with
moles of
Now we have to calculate the mass of .
Therefore, the amount of water will be, 94.86 grams

NH4NO3(s): ∆Hf = -365.56 kJ ∆Sf = 151.08 J/K.
NH3(g): ∆Hf = -46.11 kJ ∆Sf = 192.45 J/K.
H2O(l): ∆Hf = -285.830 kJ ∆Sf = 69.91 J/K.
O2(g): ∆Hf = 0.00 kJ ∆Sf = 205 J/K.
Answers
NH3: ∆G = -46.11x10^3 - (298)(192.45) = -103460.1 J
O2: ∆G = 0 - (298)(205) = -61090 J
NH4NO3: ∆G = -365.56x10^3 - (298)(151.08) = -410581.84 J
H2O: ∆G = -285.830x10^3 - (298)69.91) = -306663.18 J
∆Grex = ∆Gproducts - ∆Greactants
∆Grex = (-410581.84 + -306663.18) - (-103460.1/2 + -61090/2)
∆Grex =-634969.97 J/mol = -634.97 kJ/mol

Final answer:
Subatomic particles are particles smaller than an atom. Therefore, any element or matter larger than these particles such as molecules, compounds, or cells can be considered as non-examples.
Explanation:
The question asks for non-examples of subatomic particles, that is, elements that do not fall within the category of subatomic particles. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons. Therefore, any element or matter larger than an atom would be a non-example of a subatomic particle.
Examples of non-examples include molecules like water (H2O), oxygen (O2), or carbon dioxide (CO2). These are made up of multiple atoms and thus are larger than individual subatomic particles. Similarly, compounds like salt (NaCl) or sugar (C12H22O11) are also non-examples because they are made of multiple atoms as well. Cells, the basic structural units of living organisms, are much larger than subatomic particles and also represent non-examples.

A similarity between the separation of powers the system of checks and balances and federalism is?
A similarity between the separation of powers, the system of checks and balances, and federalism is that they all are meant to keep the federal government from becoming too powerful and tyrannical.
Answer:
Federalism and Separation of Powers policies seek for decentralised the power and avoid tyranny.
Explanation:
Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.
In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.

The ion which is most easily reduced is the cobalt (II) ion(Co²⁺).
What is reduced species?
Reduced species are those species which itself gets reduced by the addition of electrons in it, and known as the oxidizing agents as it helps in the oxidation reaction.
Among the given species according to the electrochemical seriesstrength of the metals as oxidizing agent increases in the following manner:
Ca²⁺ < Mg²⁺ < Zn²⁺ < Co²⁺
So, Co²⁺ is most easily reduced as compared to others.
