The total number of matchbooks required would 5,000 be and the cost would be $144

<h3>Mathematical ratios</h3>

50 matchbooks = $1.44

Each matchbook = 0.005 grams red phosphorus

25 grams of red phosphorus is needed:

                                 25/0.005 = 5,000 matchbooks

5,000 matchbooks will cost:

                         5000/50 x 1.44 = $144

Characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.

<h3>What is atomic theory?</h3>

Atomic theory is the scientific theory that matter is composed of particles called atoms.

The discoveries of subatomic particles such as;

  • electron by J.J. Thomson
  • proton by Ernest Rutherford
  • neutron by James Chadwick
  • nucleus by  Ernest Rutherford

all contributed in the development of the atomic theory.

From the information given in the passage J.J. Thomson experiment gave rise to atomic model while Rutherford, Geiger and Ernest Marsden, performed the experiment that discovered nucleus and proton.

Thus, characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.

What volume of a 3.00 M KI stock solution would you use to make 0.195 L of a 1.25 M KI solution?
jonny [76]
For the purpose we will use solution dilution equation:
c1xV1=c2xV2
Where, c1 - concentration of stock solution; V1 - a volume of stock solution needed to make the new solution; c2 - final concentration of new solution; V2 - final volume of new solution.
c1 = 3.00 M
c2 = 1.25 M
V1 = ?
V2 = 0.195 L
When we plug values into the equation, we get following:
3 x V1 = 1.25 x 0.195
V1 = 0.08 L
