Answer:
Answer is in the explanation
Explanation:
All acids that dissociates completely in water are considered strong acids. In the same way, bases that dissociates completely in water are strong bases. All hydroxides made from alkali metals and heavier alkali earth metals are strong bases.
HNO3 dissociates completely in water: STRONG ACID.
HCl dissociates completely in water. STRONG ACID.
NaCl is a salt. Neither a strong acid nor a strong base.
Ca(OH)2. Heavy alkaline earth metal. STRONG BASE.
CH3COOH an acid that doesn't dissociate completely in water. Neither a strong acid nor a strong base.
CH3NH2 is a weak base that doesn't dissociate completely in water. Neither a strong acid nor a strong base.
CH3OH. Methanol is an alcohol. Neither a strong acid nor a strong base.
HF is a weak acid; doesn't dissociate completely in water. Neither a strong acid nor a strong base.
RbOH. Is an hydroxide made from alkali metal. STRONG BASE.
Answer:
Kc = 826
Explanation:
For the equilibrium:
8 H₂S (g) ⇄ 8 H₂(g) + S₈ (g)
the equilibrium constant is:
Kc = [ H₂ ] ⁸ x [ S₈ ] / [H₂S]⁸
Kc = 0.600⁸ x 0.750 / (0.250)⁸ = 1.68 x 10⁻² x 0.750 / 1.53 x 10⁻⁵
= 824
Be careful with raising to the power of 8 in your calculator.
I think it is A!! Hope this helps.
Answer:
<h2>67%</h2>
Explanation:
<h2>Thus the % composition of glucose by mass is carbon 40.0 % oxygen 53.3 % hydrogen 6.7 % in this way, the % composition by mass of any compound can be calculated provided that is formed is known. </h2>
Saccharides are sugars or carbohydrates
The prefix mono means one
The prefix di means 2
Monosaccharides are 1 basic carbohydrate molecule
Disaccharides are 2 basic carbohydrate molecule
Crash course biology has a great video on this that explains the biological significance of proteins lipids carbohydrates and the nucleic acids
hope this helps
