Kerrie uses the work shown below to determine 35% of 280. Step 1: 35 percent = 10 percent + 25 percent Step 2: 10% of 280 = 280 divided by 10 = 28 Step 3: 25% of 280 = 280 divided by 4 = 70 Step 4: 28 + 70 = 98 She states that 35% of 280 is 98. Which is a true statement about Kerrie’s solution? Kerrie’s solution is correct. Kerrie incorrectly determined 10% in Step 2. Kerrie incorrectly determined 25% in Step 3. Kerrie incorrectly combined the solutions from Step 2 and Step 3 in Step 4.

how am i supposed to answer

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
