1. Make a Prediction

2. Fill both beakers with water

3. Dissolve salt in one of the beakers

4. Place both in the freezer and observe

5. Write a report

(Always make the prediction first! That's a hypothesis!)

Answer from: Har13526574

Explanation:

A hypothesis is defined as an idea or explanation which is framed without any testing or experimentation.

And, in order to verify the hypothesis we need to perform the experiment. And, on the basis of experimentation we can conclude whether our hypothesis was correct or not.

For example, when we have to perform an experiment to determine which freezes more easily—distilled water or salt water. Then the steps in this experiment should be as follows.

Make a prediction about which liquid will freeze first.Fill two beakers with 250 mL of distilled water.Dissolve 30 grams of salt in one of the beakers.Place both beakers in a freezer and observe which liquid freezes first.Write a report on his findings.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

Answer from: Quest

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
