The answer is actually (A.) Trans-radiation
T₁=17+273=290 K
7.75x10⁴.850/290 = 8.10x10⁴.720/T₂
T₂=256.74 K = -16.26°C
Answer:
The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core.
Answer:
There is at least 2 ways. First, the isotopes are allowed to heat water into steam, and the steam turns a generator. 2nd, the isotopes are allowed to heat one end of a "thermopile", and the thermopile powers electronics

Answer:
34g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
H2S + 2AgNO3 —> 2HNO3 + Ag2S
Next, we shall determine the number of mole of H2S required to react with 2 moles of AgNO3.
This is illustrated below:
From the balanced equation above,
We can see that 1 mole of H2S is required to react completely with 2 moles of AgNO3.
Finally, we shall convert 1 mole of H2S to grams. This is shown below:
Number of mole H2S = 1 mole
Molar mass of H2S = (2x1) + 32 = 34g/mol
Mass = number of mole x molar Mass
Mass of H2S = 1 x 34
Mass of H2S = 34g
Therefore, 34g of H2S is needed to react with 2 moles of AgNO3.
