Cold blooded animal? it’s a bit vague sorry
Ans: The entropy change for the given reaction is 93.3 J/K
Given reaction:
Br2(l) → Br2(g)
ΔS = ∑n(products)S⁰(products) - ∑n(reactants)S⁰(reactants)
= 1 mole* S°(Br2(g)) - 1 mole*S°(Br2(l))
= 1 mole *245.5 J/mol-K - 1 mole*152.2 J/mol-K
= 93.3 J/K
Answer:
Theoretical yield: 2.75g of paranitroaniline
Percentage yield: 54.5%
Explanation:
In strong-acid medium, acetanilide (Molar mass: 135.16g/mol) reacts producing para-nitroaniline (138.12g/mol) in a 1/1 reaction.
Theoretical yield of para-nitroaniline is the mass produced assuming a yield of 100%. That is:
2.7g acetanilide × (1mol / 135.16g) = 0.020 moles of acetanilide.
Assuming a yield of 100% are 0.020 moles of paranitroaniline. Theoretical yield is:
0.020 moles × (138.12g / mol) =
<h3>Theoretical yield: 2.75g of paranitroaniline</h3><h3 />
Percentage yield is:
(Actual yield / theoretical yield) × 100
Actual yield was 1.5g and percentage yield will be:
Percentage yield: (1.5g / 2.75g) × 100
<h3>Percentage yield: 54.5%</h3>
Answer:It is a picture with a boat sailing on the water with sound waves going down to an old and sunken ship but the waves then go back up to the boat in a different angle.
Explanation:
hope it works thx
The role of the gluons is to bind together the quarks that make up protons and neutrons. That is option D.
<h3>What are gluons?</h3>
Gluons are those particles found within an atom that are responsible for binding protons and neutrons together inside the nucleus of an atom.
The gluons are capable of binding the protons and neutrons together by holding together the quarks that makes up protons and neutrons.
These gluons are known to carry a color-anticolor charge which makes up the 9 types of gluons which include:
An atom is the smallest indivisible part of an element that can take part in a chemical reaction.
The proton is the positive particle of an atom which is found within the nucleus.
The neutron is the particle that is found in the nucleus of an atom which doesn't have any charge.
