The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are vibrating in place.
As these molecules heat up, they will vibrate more vigorously, and will eventually turn to water, then gas.
Answer:
answer number C is the correct answer for this
To express the answer of (6.93 x 10¹) (2.0 x 10-4) in scientific notation, it should be 1.4 x 10^-2. <span>To </span>multiply<span> two numbers expressed in </span>scientific notation<span>, simply </span>multiply<span> the numbers out front and add the exponents. I hope it helps. </span>
First, we need to convert the grams of gold into mole using the molar mass (molecular weight) of gold, and then into particles using avogadro's number (1 mol= 6.02 x 10^23)
molar mass of gold= 197 grams/ mole
100.0 grams (1 mole/ 197 grams) x (6.02 x 10^23 particles/ 1 mole) = 3.06 x 10^23
