Answer:
B. gas mixed with a liquid
Explanation:
because:
A. a solid can't dissolve in a liquid.
C. two liquids mixed isn't a solution
D. Not All of the above for sure.
The answer is B, maltose.
Maltose is a disaccharide, composed of two monosaccharide. It can be broken down by amylase, a enzyme, from starch, a polysaccharide. Maltose is also important in beer, even though it is decomposed into ethanol by yeast.
Maltose is only only disaccharide that matches the description so the answer is B.
Properties change within a Row (or period) as the number of valence electrons in the outer shell increase
Two [hydrogen] atoms and one [oxygen] atom
Answer:
concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 0.0248 = 2.48 ×10⁻² M
concentration of = 0.4442 M
Explanation:
Equation for the reaction:
⇄ +
Concentration of = = 0.469
For our ICE Table; we have:
⇄ +
Initial 0.469 0 0
Change - 2x +2x +x
Equilibrium (0.469-2x) 2x x
K =
K =
Since the value pf K is very small, only little small of reactant goes into product; so (0.469-2x)² = (0.469)²
x = 0.0124
∴ at equilibrium; concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 2x = 2 ( 0.0124)
= 0.0248
= 2.48 ×10⁻² M
concentration of = 0.469-2x
= 0.469-2(0.0124)
= 0.469 - 0.0248
= 0.4442 M
