gtnhenbr [62]

Answer:

The unknown solution had the higher concentration.

Explanation:

When two solutions are separated by a semi-permeable membrane, depending on the concentration gradient between the two solutions, there is a tendency for water molecules to move across the semi-permeable in order to establish an equilibrium concentration between the two solutions. This movement of water molecules across a semi-permeable membrane in response to a concentration gradient is known as osmosis. In osmosis, water molecules moves from a region of lower solute concentration or higher water molecules concentration to a region of higher solute concentration or lower water molecules concentration until equilibrium concentration is attained.

Based on the observation that when the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises, it means that water molecules have passed from the glucose solution through the semipermeable membrane into the unknown solution. Therefore, the solution has a higher solute concentration than the glucose solution.

In a chemical reaction, mass is conserved. this means that...
sergij07 [2.7K]
Atoms are the smallest particales of an element that can take part in a chemical reaction. During a chemical reaction no particles are created or destroyed. The atoms are simply rearranged from the reactants to the products, mass is NEVER lost or gained in chemical reactions...Mass is ALWAYS conserved. :) Hope this helped

Describe the pH changes expected if an acid is used to neutralize a base with pH 12
antoniya [11.8K]

By adding acid to a basic solution of pH 12, the overall solution becomes less basic and the Ph of solution decreases to a value of 7, which is known as the pH of a neutral solution, i.e neither basic nor acidic. This process is called neutralizing the base.

What is the number of moles in 432 g Ba(NO3)2? A. 0.237 mol B. 0.605 mol C. 1.65 mol D. 3.66 mol
Montano1993 [528]

Answer:

C

Explanation:

Since Moles=mass/molar mass

Mass=432g

Molar mass=261g/mol

Moles=1.65mol
