The conditions that cause hail to fall are unstable air that move water droplets through layers of warm and freezing air repeatedly. Therefore, option A is correct.
What is droplet ?The temperature determines whether water vapor will condense into droplets. The dew point is the temperature at which droplets begin to form. The atmospheric water vapor condenses to create tiny droplets on the surface when the temperature of the surface falls until it eventually reaches the dew point.
When a water droplet is lifted by an updraft from a thunderstorm over the freezing point of the atmosphere, hail is created. The super-cooled water or water vapor that the frozen water droplet accretes later freezes when it comes into contact with it. A hailstone grows as a result of this process.
Thus, option A is correct.

under which conditions do gases behave most ideally? select all that apply. multiple select question. when gas particles are small at high temperatures at low temperatures at low pressures when gas particles repel each other
Under very low temperature or high pressure the gases behave the most ideally.
A theoretical gas known as an ideal gas is made up of several randomly moving point particles with no interparticle interactions. [1] Because it abides by the ideal gas law, a condensed equation of state, and is amenable to statistical mechanics analysis, the ideal gas concept is helpful. If, for instance, the interaction is totally elastic or is thought of as point-like collisions, the constraint of zero interaction can frequently be disregarded.
Many real gases behave qualitatively like an ideal gas under various temperature and pressure settings, where the gas molecules (or atoms for monatomic gases) take on the function of the ideal particles.

the reaction for the oxidation of nh3 is given as: 4 nh3 5 o2 → 4 no 6 h2o under certain conditions the reaction will proceed at 29.8% yield of no. how many grams of nh3 must be made to react with excess oxygen to yield 70.5 g of no?
134g of NH3 is required to react with excess oxygen to make 70.5 g of NO
We need to prepare 70.5 of NO given that the percent yield is 29.8%. Therefore, the molar mass of NO is 30g/mol. Then, the number of moles of NO in 70.5g is given by,
Moles of NO = 70.5/30
Moles of NO = 2.35moles
The actual yield of NO is 2.35 moles. Then theoretical yield can be computed as follows,
The percent yield of NO=( actual yield of NO/theoretical yield of NO ) x 100
Theoretical yield of NO = (actual yield/percent yield/100)
On supplying the values we get,
Theoretical yield= 2.35/0.298
Theoretical yield = 7.88 moles
The reaction is given by
4NH₃+SO₂ ---------> 4NO + 6H₂O
4 moles of Ammonia are required to make 4 moles of NO. Then, moles of NO equals moles of NH₃ which is 7.88
Then molar mass of NH₃ = 17g/mol
Mass of NH₃ = molar mass x no of moles
Mass of NH₃ = 17x7.88
Mass of NH₃ = 134g.
Therefore 134g of NH3 is required to make 70.5g of NO.

the speed at which an electron can transfer or jump from a chemical species (referred to as the electron donor) to another (called the electron acceptor). Rudolph A. Marcus created the Marcus Hush theory (M-H theory) in 1956. It describes the foundations of redox/ electron transfer processes in terms of the rate at which an electron jumps/moves from an oxidant species (electron donor) to the reductant (electron acceptor). When the free energy is equal to the reorganisation energy and is in the opposite direction, the maximum rate constant for electron transfer occurs. Keep in mind that the reorganisation energy is positive and the free energy for a spontaneous electron transfer is negative.is favourable. In addition to the structural changes mentioned above, substitution, elimination, and isomerization reactions differ from outer sphere redox reactions in that nuclear configurations and charge distribution are always "in equilibrium" and that nuclear movements and charge shifts (charge transfer, CT) occur continuously and concertedly on the reactions path.

It is given that the concentration of sugar in a soft drink is 0.375M It means 1L of soft drinks contains 0.375mol of sugar. Then,
1000mL = 0.375mol
1mL =0.375/1000
For 10ml
= 0.375 x 10^-3 x 10
= 0.00375mol sugar
Now, the concentration of sugar in sweetened tea is 0.05M.
This means 12 L solution (tea) contains 0.05mol of sugar.
Now, we need to find the volume of sweetened tea that has the same mass of sugar that is present in 10ml of soft drink
So, the required amount of sugar is 0.05 mol
0.05mol sugar = 1000ml (tea)
1 mol sugar = 1000/0.05 (tea)

When stored, it reacts with oxygen and forms a layer of magnesium oxide on the surface. This layer of magnesium oxide is very stable and prevents further reactions between magnesium and oxygen. Clean the magnesium ribbon with sandpaper to remove this layer and expose the underlying metal to the air.

Energy-releasing processes are said to be positive since the chemical reactions end products are in a more stable and advantageous condition afterward. It's because the reactions follow a predetermined course, and that course necessitates the use of energy (known as activation energy) in order to create an activated complex chemical reaction, which will ultimately result in the synthesis of the products. This implies that in order to begin, the products must absorb some energy (the activation energy).
