<p>@Indiangurl i got 1/4.</p>

<p>For the structure of ethanol, if I drew two attached to each other will that be marked wrong? </p>

<p>Seems like some people here are disagreeing on some answers o.o Now im scared to find out what i got. Hope i passed!</p>

<p>How was it 1/4?</p>

<p>@Indiangurl‌ it was 1/4</p>

<p>@Indiangurl Two half-lives past (1/2)^2 = 1/4</p>

<p>But didn’t it ask for 24. Something? Isn’t that one half life or not…</p>

<p>The half life was 12 years</p>

<p>you had to do the half life so 12.34 or something divided by 24.72 something and it came to 1/2</p>

<p>For the first short answer what did u guys do?</p>

<p>@indiangurl do you mean the drawing or the second short answer? </p>

<p>Yup it was 1/4</p>

<p>the half life of helium was like 12 years I think so in 26 years it goes in approximately 1/4 if I am correct </p>

<p>U guys remember the equation for the yeast? For the product it was ethanol but if it had a coefficient of 2 would you draw two separate structure for ethanol?</p>

<p>The drawing @Saswizy‌ </p>

<p>@Sdhillon275 that was what confused me. I drew two ethanols attached to each other but I’m not sure if that is correct. But I thought since there was a coefficient so then don’t you have to distribute it? ahh so confusing!</p>

<p>For the dot diagram for bromomethane, did u have to put dots around the bromine? And also I think you can get 1 question wrong and still get a 98, not a 96</p>

<p>And isn’t the solid potassium bonding metallic bonding? It isn’t ionic binding because ionic means a metal and a nonmetal </p>

<p>@saswizy for that one, I did that but I drew lines symbolizing the electron pairs. Mine looked like that but I jut had the electron lines instead. Like I drew that same picture too, but I also did one with the lines that represented the electron sharing. Is that okay?</p>
