Answer:
Hydrogen-1
Explanation:
Not sure what kind of explanation is needed for your question, because it doesnt specify.
The easiest should be:
Average mass of an element is calculated as the sum of the multiplication of each isotope by its percentage
And the mass of the hydrogen is 1, therefore the more abundant is hydrogen-1
The major visible difference between<span> the two are crystal size, </span>intrusive rocks<span> have a larger crystal/grain texture due to the slow cooling of magma below the earth surface which encourages the growth of larger crystals, while </span>extrusive rocks<span>, because of the rapid cooling at/above the earth's surface does the opposite. Hope I helped</span>
This particular law is a gas law, called Charle's Law. The formula is:
V1 V2
---- = ----
T1 T2
So we know our original volume is 4.0L, so we would plug that into our V1. We know T1 is the 30 degrees, since it relates to our original volume. However, we need to convert it to kelvin. We do this simply by adding 273 degrees to the 30 degrees, since 273 is the constant for kelvin.
We do not know our second volume, however we know out T2. It is -8 degrees, and don't forget to convert it to Kelvin.
So, when we plug all of these numbers into the equation, we are left with V2 to find. To do this we cross multiply (V1 x T2) and then divide by T1. That leaves us with the number for V2. Don't forget to round to the least # of sig figs! And you can divide V1 by T1, and then divide V2 by T2, to ensure your answers are the same, since they are directly porportional and need to be equal to each other.
Hope I could help!
