The impact of speed and velocity at greater speeds affects the car much greater than at slower speeds due to impact and timing and velocity and speed.
Answer:
idek this is so confusing
Explanation:
Answer:
<span>Given mass of C is 32.0 grams
</span><span>Given mass of H is 8.0 grams
</span>Molar mass of C is 1212 g/mol
Molar mass of H is 1.01 g/mol
Thus
<span><span><span><span>32.0 grams of C </span><span>8.0 grams of H </span></span><span><span>→<span>3212</span>=2.66 moles of C</span><span>→<span>81.01</span>=7.92 moles of H</span></span></span><span><span><span>32.0 grams of C </span><span>→<span>3212</span>=2.66 moles of C</span></span><span><span>8.0 grams of H </span><span>→<span>81.01</span>=7.92 moles of H</span></span></span></span>
<span>When we divide 7.92 by 2.66 we obtain 2.977 which is approximately 3. This means that the ratio of atoms of </span><span>CC</span><span> to the atoms of </span><span>HH</span><span> is 1:3.</span>
<span>Thus, empirical formula for the compound is </span><span><span>C<span>H3</span></span><span>C<span>H3</span></span></span>.
<span>Molar mass of </span><span><span>C<span>H3</span></span><span>C<span>H3</span></span></span><span> is </span><span><span>1⋅12+3⋅1.01=15.03</span><span>1⋅12+3⋅1.01=15.03</span></span><span>. Since molar mass of the compound we have to find is </span><span>3030</span><span> g/mol we have tu multiply subscripts by 2.</span>
<span>Thus, final compound is </span><span><span><span>C2</span><span>H6</span></span><span><span>C2</span><span>H6</span></span></span>.
It's Fluorine (non-metal) whose E.C. is 1s2, 2s2, 2p5
& Cesium (metal) whose E.C. is [Xe] 6s1
1. P<span>eriodicity (the repetition of several properties in a row on the Periodic Table)
2. Noble Gas (Noble gases are located in group 18 on the Periodic Table)</span>
