1. the Moon must be in line with the Earth and Sun - New Moon for a solar eclipse and Full Moon for a lunar eclipse.2. the Moon must be at one of its nodes. Most of the time the Moon at New or Full passes above or below the Sun because its orbit is tilted relative to the ecliptic. An eclipse can occur only when it is at a node, in other words crossing the ecliptic.
It’s either not testable since hypothesis need to be able to be tested or it could be not likely tho second option it has been poorly written
Welp ur screwed

The series of reactions is:
4 NH3 + 5 O2 → 4 NO + 6 H2O <span>
6 NO + P4 → P4O6 + 3 N2
P4O6 + 6 H2O → 4 H3PO3
4 H3PO3 → PH3 + 3 H3PO4 </span>
<span>
We multiply the first equation by a number 3 and all the
other equations by number 2, so that we get:
12 NH3 + 15 O2 → 12 NO + 18 H2O
12 NO + 2 P4 → 2 P4O6 + 6 N2
2 P4O6 + 12 H2O → 8 H3PO3
8 H3PO3 → 2 PH3 + 6 H3PO4
Then the overall reaction is:
12 NH3 + ... → 2 PH3 + ...
</span>
<span>So calculating for PH3:
<span>(1.10 g NH3) / (17.0306 g NH3/mol) x (2/12) x (33.9976 g
PH3/mol) = 0.366 g PH3</span></span>
Answer:
d
