Question 3 of 12 4.0 points `if you drop mg into hcl, you will evolve hydrogen gas. if you perform this reaction over water at a temperature of 298.15 k at a pressure of 0.977 atm, and the vapor pressure of water at this temperature is 0.0313 atm, what is the pressure of hydrogen?

What are the genotypic and phenotypic ratios

What is the most important factor in determining climates.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
