Answer:
°C = °K - 273.
Explanation:
the 1st and 2d rows belong to F°; the last one is wrong; correct answer is °C=°K-273 only.
For example, 0°C=273°K; 10°C=283°K; 100°C=373°K.
Answer: 243 hours
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 
a - x = amount left after decay process = 
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for reducing the mass to 10.00 % of its original mass
The time taken to reach 10.00 % of its original mass is 243 hours
Answer:
0,72 moles of SO₂ remain
Explanation:
The reaction is:
2SO₂ + O₂ → 2SO₃
Where molecular mass of SO₂ is 64,066g/mol and of SO₃ is 80,066g/mol.
86,0g of SO₂ are:
86,0g × (1mol / 64,066g) = <em>1,34 moles of SO₂</em>.
50,0g of SO₃ are:
50,0g × (1mol / 80,066g) = <em>0,62 moles of SO₃</em>.
Now, as 2 moles of SO₂ produce 2 moles of SO₃, the moles of SO₂ that remain after the reaction are the initial moles of SO₂ - moles of SO₃:
1,34 moles - 0,62 moles =
<em>0,72 moles of SO₂ remain</em>
I hope it helps!
Your question should accompanied with choices. The mino acids contains a side chain that is polar and uncharged from pH 1-13 is <span>Gln
