So Helium walks into a bar and orders a beer...
The bartender says, "Sorry we don't serve noble gases here."
Helium doesn't react.
Answer:
Options a,b, c and d are correct
Explanation:
From the diagram attached in the picture below, They both have steroid nucleus since they have functional groups (such as the methyl and the ketone groups) that are spatially attached. It can also be deduced that both structures have three (3) ketone groups (CO/C=O), two (2) methyl groups (CH₃) and two (2) hydroxyl groups (OH). Hence, options a, b,c and d are correct.
However, cortisone has one (1) double bond while prednisone has two (2) double bonds.
Answer:
(Highest kinetic energy)
3. Neon at 65 K and 15 atm
2. Neon at 55 K and 10 atm
4. Neon at 25 K and 5 atm
1. Neon at 5 K and 0 atm
(Lowest kinetic energy)
Explanation:
In gases, <em>kinetic energy is higher the higher the temperature is</em>. This is because the molecules have more available energy under those conditions. <u>Generally there's also an increase in kinetic energy if there's an increase in pressure</u> -assuming there's no phase changes ie. the gas condenses into a liquid-.
Answer:
4.23.
Explanation:
<em>∵ pH = - log[H⁺].</em>
<em>For weak acids:</em>
∵ [H⁺] = √(ka)(c).
∴ [H⁺] = √(3.5 × 10⁻⁸)(0.10 M) = 5.92 x 10⁻⁵.
∴ pH = - log[H⁺] = - log(5.92 x 10⁻⁵) = 4.2279 ≅ 4.23.
Answer:
Volume would be 13
Explanation:
Divide the mass by the density
65/5
