How would I solve for 7.50 x 10 squared ml of a 0.000450 M MgSO4 solution?

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.
