Kool-Aid itself is actually a mixture of sugar, water, dye, and flavoring. So when we add our sugar crystals, the water molecules and sugar molecules in the Kool-Aid will come in contact with the surface of our pure sugar crystals.
plz mark me as brainliest :)
Answer:In biology, a key idea is that structure determines function. In other words, the way something is arranged enables it to play its role, fulfill its job, within an organism. Structure-function relationships arise through the process of natural selection.
yes, because they are combined in different ratios.
Answer:
Have you ever seen a "shooting star" race across the sky at night? Shooting stars are meteors zooming at high speed through Earth's atmosphere and burning up along the way from friction. And right now is one of the best times to see them in person. The Perseids, which are impressive meteor showers that happen each year from mid-July to late August, have their peak activity around August 11 to 14. They're caused by Earth traveling through debris from the Comet Swift-Tuttle. Luckily, most meteors are tiny and burn up before hitting the ground. But if a meteor doesn't disintegrate, what's its impact on Earth? In this activity you'll explore how a meteorite’s size is related to the size of the crater it makes on impact..
Explanation:
Van der Waals equation is as follows:
(P + a(n/V)²) * (V -nb) = n RT
Moles of H₂ is calculated by dividing 25 g by 2 (molecular weight of H₂) = 12.5 moles
Values of a and b are:
a = 0.02444 atm L² / mol
b = 0.0266 L / mol
(P + 0.02444 (12.5/1)²) * (1 -(12.5 *0.0266)) = 12.5 * 0.0821 * 293 K
If we solve this equation we get pressure of 412.29 atm
With ideal gas equation we get:
P V = n R T
P = n * R * T / V = (12.5 * 0.0821 * 293 / 1) = 300.69 atm
