Chemistry
1 answer:
Vinil7 [7]3 years ago
3 0
What you need to do is like this:
ΔSrxn∘ = Products - Reactants 
<span>ΔSrxn∘ = [NO2 (mols*S∘)] - [NO (mols*S∘) + O2 (mols*S∘)] </span>
<span>ΔSrxn∘ = [(2 mol * 240.0 J/mol*K)] - [(1 mol *205.2 J/mol*K) + (2 mol *210.8 J/mol*K)] </span>
<span>ΔSrxn∘ = [480 J/K] - [626.8 J/K] </span>

<span>ΔSrxn∘ = -146.8 J/K
</span>I hope this is good for you

Leno4ka [110]

Answer:

It has been approximately 6 hours after death.

Explanation:

This is because between 2-6 hours after death, the body starts becoming stiff from top to bottom, then spreading to the limbs. Since there is only rigor in his upper body, that would mean that with normal temperature and body conditions, it would be 4 or 5 hours after death. But since he is obese and in cold temperature, there is slower progression of rigor, leading to the maximum time in the first rigor mortis phase, 6 hours.

Identify the missing daughter nucleus in the β– emission decay of 106ru below.
kotykmax [81]
Answer is: <span>the missing daughter nucleus is rhodium (Rh).</span>

Nuclear reaction: ¹⁰⁶Ru → ¹⁰⁶Rh + e⁻(electron) + ve(electron antineutrino).

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.There are two types of beta decay: beta minus and beta plus.

<span>In beta minus decay, neutron is converted to a proton and an electron and an electron antineutrino.
In beta plus decay, a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.</span>

The impact of fossil fuel combustion on the global carbon cycle
olga_2 [115]
When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.
