The na+-k + pump actively transports both sodium and potassium ions across the membrane to compensate for their constant leakage. in which direction is each ion pumped?

Write the mathematical expression that allows you to solve for the oh - concentration in water when you know only the h3o + concentration.

Classify the reaction: N2 (g) + 3H2 (g) à 2NH3 (g)

Methane, CH4, reacts with chlorine, Cl2, to produce a series of chlorinated hydrocarbons: methy chloride (CH3Cl), methylene chloride (CH2Cl2), chloroform (CHCl3), and carbon tetrachloride (CCl4).

Why is it important to repeat the steps or an experiment multiple time

A certain reaction has the following general form. aA → bB At a particular temperature and [A]0 = 2.80 ✕ 10-3M, concentration versus time data were collected for this reaction, and a plot of 1/[A] versus time resulted in a straight line with a slope

Assuming that air contains 78 percent N2, 21 percent O2 and 1 percent Ar, all by volume. How many molecules of each type of gas are present in 1.0 L of air at STP?

Two children are playing tag. Child A who is doing the chasing can run 100m in 24 seconds Child B is running away from child A and can run 64m in 21 seconds.

What ion does a base increase

What is the definition of Amplitude?

An excess of NiCO3, 12 g, was added to 40cm cube of sulpheric acid, 2.0 mol/dm cube. The unreacted nickel carbonate was filtered out and the filtrate evaporated to optain the crystals.
