What would you predict about a chemical that has a hydrogen ion concentration of 1 × 10^−12 m?
a) it will form salt and water when added to a base.
b) it contains no hydroxide ions.
c) it has high concentration of hydroxide ions.
d) it has a sour taste.
it's not b, and i'm pretty sure that it's not c what would it be?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

If forces acting on an object are unbalanced. true or false

Which of the following are appropriate acceleration units?
