As you travel up the air pressure decrease, so then the amount of oxygen you use to breathe also decreases
Answer:
Halogens are used in, water and sanitation, plastics, pharmaceutical, pulp and paper, textile, military and oil industries. Bromine, chlorine, fluorine and iodine are chemical intermediates( bleaching agents and disinfectants). Chlorine is used to purify water. Chlorine also is part of salt, sodium chloride, which is one of the most widely used chemical compounds. Fluorine is used in fluorides, which are added to water supplies to prevent tooth decay.

The answer in this question is just easy and simple, since there are lots of <span>different enzymes being secreted in the stomach (the enzymes are made of protein and can be denatured by alternation of pH, each of these enzymes required to have a specific optimal pH. </span>
Answer:
K = 8.6x10⁻⁶
Explanation:
<em>a chemist finds that a 5.2L reaction vessel...</em>
To solve this question we need first to find the equation of the equilibrium constant using the chemical eqiation:
TiCl₄(l) ⇄ Ti(s) + 2Cl₂(g)
The equilibrium constant expression is:
K = [Cl₂]²
<em>Because equilibrium constant is defined as the ratio berween concentrationa of products over reactant powered to its reaction coefficient. But pure liquids as TiCl₄(l) and pure solids as Ti(s) are not taken into account</em>
<em />
Now, we need to find the molar concentration of Cl₂, [Cl₂]:
<em>Moles Cl₂ -Molar mass: 70.9g/mol-:</em>
1.08g * (1mol / 70.9g) = 0.0152 moles / 5.2L =
2.93x10⁻³M = [Cl₂]
K = (2.93x10⁻³)²
<h3>K = 8.6x10⁻⁶</h3>
