So this is p1 over t1 = p2 over t2. So you do 880/250=x/303 and then cross multiply and divide

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 5.61 moles CO₂

[Solve] molecules CO₂

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 5.61 \ mooles \ CO_2(\frac{6.022 \cdot 10^{23} \ molecules \ CO_2}{1 \ mol \ CO_2})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 3.37834 \cdot 10^{24} \ molecules \ CO_2$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

3.37834 × 10²⁴ molecules CO₂ ≈ 3.38 × 10²⁴ molecules CO₂

Which ion has the smallest radius?<br> (1) O2-<br> (2) S2-<br> (3) Se2-<br> (4) Te2-

podryga [215]

Answer:

Option-1 (O²⁻) is the correct answer.

Explanation:

All given anions contains same charge. So, we can ignore the effect of charge on these anions.

As we know all given compounds belongs to same group (Group 6) in periodic table. And from top to bottom along the group the elements are placed as,

Oxygen O

Sulfur S

Selenium Se

Tellurium Te

Hence, moving from top to bottom along the group the number of shells increases. And with increase in number of shell the atomic or ionic radii increases. As Oxygen is present at the top of the group, therefore, it has the smallest radius due to less number of shells.
