Ответ:
When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Explanation:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
Ответ:
CH4 + 2O2 --> 2H2O + CO2,
That means for every 1 molecule of methane(CH4) there will be one molecule of carbon dioxide(CO2) produced. Methane molecular weight 16, carbon dioxide molecular weight is 44. Then the percent yield should be:
1 * (0.374/ 16) /(0.983/44)= 0.374*44/ 0.983 * 16= 104.6%
You sure the number is correct? Percent yield should not exceed 100%
