A
Explanation:
Im just guessing its half of 200 as it says
Final answer:
The actual yield of a reaction, where only 50% of a theoretical yield of 200g is formed, is 100g.
Explanation:
The actual yield refers to the amount of product that is actually formed when the reaction is carried out in a real-life setup. In this case, if the theoretical yield (which is the amount of product predicted by stoichiometric calculations) is 200g but only 50% is actually formed, then the actual yield would be 50% of the theoretical yield. Hence, the answer will be 50% of 200g i.e., 100g.

Answers
Answer: Option (d) is the correct answer.
Explanation:
When people or group of people work collectively or work together in order to achieve a certain aim then it is known as collectivism.
In collectivization, people help each other.
Thus, we can conclude that it is important we work together on this project; we want our group to succeed.” This statement reflects collectivization.
Answer:

Explanation:
A neutralization reaction is a reaction that involves acid and base with the production of salt and water as the end products. An example is as below:
HCl + NaOH --> NaCl + H2O
The salt produced here is NaCl. In solution, NaCl will ionize as:
Hence, the salt's positive ion (Na+) was contributed by the base (NaOH) while its negative ion (Cl-) was contributed by the acid (HCl).
Final answer:
In a neutralization reaction involving Ba(OH)2 and HNO3, the salt's positive ion comes from the base and the negative ion comes from the acid. In the molecular and net ionic equations, spectator ions, which are unaltered in the process, are included and excluded respectively.
Explanation:
In a neutralization reaction, an acid and a base react to produce water and a salt. Taking the provided reaction of Ba(OH)2 (aq) + 2HNO3(aq) → Ba(NO3)2(aq) + 2H₂O(1), the salt's positive ion (Ba²+), also known as the cation, comes from the the base, Ba(OH)2. The salt's negative ion (NO3-), also known as the anion, comes from the acid, HNO3. This reaction also represents a molecular equation where all reactants and products are represented as neutral substances. A net ionic equation would exclude the spectator ions, ions whose presence is required to maintain charge neutrality but are chemically and physically unaltered by the process.

To determine the oxidation numbers, we assign oxidation numbers to each element in the equation.
1. Fe: The oxidation number of Fe is 0 since it is in its elemental form.
2. H2SO4:
- H has an oxidation number of +1.
- S has an oxidation number of +6 since it is in the sulfate ion (SO4)2-.
- O has an oxidation number of -2.
3. Fe2(SO4)3:
- Fe has an oxidation number of +3 since it is in the Fe2+ ion.
- S has an oxidation number of +6 since it is in the sulfate ion (SO4)2-.
- O has an oxidation number of -2.
4. H2:
- H has an oxidation number of 0 since it is in its elemental form.
Now, let's analyze the oxidation and reduction parts of the equation:
Oxidation: Fe is oxidized from an oxidation number of 0 to +3 in Fe2(SO4)3.
Reduction: H2SO4 is reduced. The sulfur (S) in H2SO4 goes from an oxidation number of +6 to +4 in Fe2(SO4)3, and the hydrogen (H) in H2SO4 goes from an oxidation number of +1 to 0 in H2.
Overall, in this equation, Fe is oxidized, and H2SO4 is reduced.

if we change these values into Kelvin then
melting point of water is 273.15 K and boiling point is 373.15 kelvin..
for melting it is necessary for ice to get warm so it attains heat 10 F to 32 F...
then ice melts but during this temperature remains constant..
the energy required for melting is 333 kJ/Kg K
then water is warmed at 305 Kelvin.... :)
