Answer: 37.0 °C , 42.5 °C
Explanation:
A species whose oxidation number increases in a reaction is oxidized (reducing reagents or reactant).
For example, balanced chemical
reaction: 2KClO₃ → 2KCl + 3O₂<span>.
</span><span>Oxygen in the
reactant state has oxidation number -2 (+1 + 5 + 3 · x = 0) and it is
oxidized to 0 (in molecule of oxygen) in the product state.</span>
Answer:
1.2 x 10>24 (2.0)(6.022 x 10>23)
Explanation:
How many formula units are in 2.0 moles of Fe(NO3)2?
Answer:
85.384 atm or 64608.13086 mmHg
Explanation:
PV= NRT
P= NRT/V
n= mols
R= gas constant (i used .0821 for atm)
T= Temp in Kelvins (Celsius degrees + 273)
V= in L
(65molsx480kx.0821)/30L
Answer:
<h2>169.96 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
volume = 97.68 cm³
density = 1.740 g/cm³
mass = 97.68 × 1.740 = 169.9632 g
We have the final answer as
<h3>169.96 g</h3>
Hope this helps you
