All onions contain chemicals called amino acids. One of the chemicals in the onion's amino acids is sulfur. When the onion's skin is cut it brings this sulfur into contact with special proteins, called enzymes (EN-zimes). A gas then forms, which can make your eyes burn if it comes in contact with them
AC2
A will lose 2
C will gain 1
Need two Cs to match A
Answer:
b) increases by a factor of about 2.
Explanation:
Ignore the nitrogen and oxygen. Each gas acts independently of the others.
You have 0.02 mol of CO₂ gas at some pressure in equilibrium with the CO₂ in solution.
According to Graham's Law,
S = kp
That is, the solubility of a gas in a liquid is directly proportional to its partial pressure above the liquid.
If you add another 0.02 mol of CO₂, you have doubled the number of moles.
According to Avogadro's Law, doubling the number of moles doubles the pressure.
According to Graham's Law, doubling the pressure doubles the solubility.
The solubility of CO₂ increases by a factor of two.
Answer:
Chromium, calcium, and osmium
Explanation:
These elements are metals, considering this, these elements electron shells(orbitals) are further away from the nucleus, with this, their attractions are not as strong as non-metals, so some of their electrons are able to move freely.
When you accumulate many atoms, these metals can form a "sea of electrons" because they all have loose electrons interacting with each other. This allows easy conduction of heat and electricity.
Aqueous nitric acid and aqueous ammonia reacts to form ammonium nitrate
HNO₃(aq)+NH₃(aq) = NH₄NO₃(aq)
HNO₃ +NH3 = NH₄ (+) + NO₃ (-)
Therefore the net ionic equation will be;
H⁺(aq) + NH₃ = NH₄⁺ (aq)
