Answer:
n O2 = 2.125 mol
Explanation:
balanced reaction:
- 2C6H10 + 17O2 → 12CO2 + 10H2O
∴ n CO2 = 1.5 mol
⇒ n O2 = (1.5 mol CO2)*(17 mol O2/12 mol CO2)
⇒ n O2 = 2.125 mol
Helium is a chemical ELEMENT of the family of noble gases. Its chemical symbol is 'He' which has an atomic number of 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Although it doesn't really react under normal conditions, it is the second most abundant element in the universe.
Elements are pure substances that cannot be broken down any further.
Answer:
pH = -log₁₀ [H⁺]
Explanation:
pH is a value in chemistry used in to measure solution trying to determine each quality, purity, risks for health of some products, etc.
As you write in the question, [H⁺] = 10^(-pH)
Using logarithm law (log (m^(p) = p log(m):
log₁₀ [H⁺] = -pH
And
<h3>pH = -log₁₀ [H⁺]</h3>
Answer:
neutralization reaction! Aka: option C!
HOPE THIS HELPS! :)
Explanation:
Answer:
Reactants break bonds with consuming the energy and form the new bonds .
Explanation:
As the two molecules interacted with each other , the elements reshuffled the bonds and formed the new ones with shifting the energy and converting it into new products .
