Answer:Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest. So the asnwer is helium

Elanso [62]

Answer:

d) 0.1202 M

Explanation:

Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.

NaOH + HA → NaA + H₂O

The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:

22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol

The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.

The molar concentration of HA is:

2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M

For each of these terms, give an example and a non-example.
gizmo_the_mogwai [7]

Given what we know, we can confirm that an example is a situation given that corroborates the information shown, while a non-example is one that does not fall in line with the information provided.

<h3>What are examples of the situations given?</h3>
  • A number that is a multiple of 10 is 40, since 10 times 4 equals 40.
  • In order to get a product of 10, we can multiply two and five.
  • To result in a quotient of 10, we can divide one hundred by ten.

<h3>What are non-examples of the situations given?</h3>
  • one non-example of a multiple of 10 would be to multiply three and seven.
  • A non-example of a product of 10 is to multiply the number fifty by twenty-five.
  • To result in a non-example for a quotient of 10, we can divide the number fifteen by three.

Therefore, given the definition of an example as a situation given that corroborates the information shown, while a non-example is one that does not fall in line with the information provided, we can confirm that the ones listed above are correct.
