Question:

How much heat must be absorbed by 580 grams of water to raise its temperature by 50° C?

Inactive
Brett P.

Mass (m) = 580 g Specific heat of water (c) = 4.18 J/g·K Change in Temperature (∆T) = 50°C => (273 + 50°C) = 323 K q= mc∆T q = 580 g x 4.18 J/g·K x 323 K = 783,081.2 J or 7.8x10^5

Lewis Theory: An acid is an electron acceptor and a base is an electron donor. Bronsted-Lowry Theory: An acid is a proton (H+) donor and a base is an H+ acceptor. Arrhenius Theory: An acid is any substance that dissociates to form H+ ions when placed in an aqueous solution and a base is any substance that dissociates to form OH- ions when placed in an aqueous solution.

Question:

A woman who is hypertensive switches from NaCl in her diet to KCl. What would the long-term result be?

Inactive
Brett P.

Result: Increased activity of the Na+/K+ ATPase in the Principle Cells of the kidneys. Substituting KCl into the diet increases plasma levels of K+, which, in turn, stimulates Aldosterone release. Aldosterone stimulates the Na+/K+ ATPase in Principle Cells, which consequently increases K+ secretion in Principle Cells.
