Natali [406]2 years ago
5 0

Answer:

it is an exothermic reaction

Explanation:

exothermic reactions have a negative ∆H

i.e, product of the reaction is less that the reactants of the reaction

(Note : ∆H= products - reactants), that's why it's exothermic

Which of the following correctly describes the difference (on average) between an electron in a 2s orbital and an electron in a
bulgar [2K]

Answer:

C: electrons is the 3s orbital are higher than those in the 2s orbital

Explanation:

Looking at the options, the correct one is that the electrons in the 3s orbital will possess more energy than those in the 2s orbital. This is because the the 2s orbitals will be filled with electrons first before the 3s orbital.

Also from basics we know that the energy of an orbital increases as the quantum number increases.

A sample of o2 gas (2.0 mmol) effused through a pinhole in 5.0 s. it will take __________ s for the same amount of co2 to effuse
s344n2d4d5 [400]
Answer is: 5,9.
Effusion is leakage of gas through a small hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
</span>M(O₂) = 32g/mol.
M(CO₂) = 44g/mol.
t₁ = 5s.
t₂ = ?
t₂/t₁ = √(M(CO₂)/M(O₂)).
t₂ = 1,17·5s = 5,9s.
