Answer:
the discovery will always need to be tested more where if you're investigating you should already be in a more controlled environment
Answer:
54.99% yield
Explanation:
percent yield is just the amount you obtained over the amount expected times 100%.
(experimental value/theoretical value) x 100%
= (107.9 g/196.2 g) x 100%
=54.99% yield
Answer:
Nearly all of the water astronauts drink and shower with comes from their urine and sweat. Storage is hard to come by aboard the International Space Station. Even if a rocket had room to ferry thousands of pounds of water and oxygen to supply a six-month mission, you'd struggle to find anywhere to stash it.
Explanation:
°C + 273.15 = K. The basic formula for converting Fahrenheit into Celsius is (°F − 32) × 5/9 = °C. To convert Fahrenheit degrees into Kelvins, (°F − 32) × 5/9 + 273.15 = K.
Answer :
(a) displacement reaction
(b) combination reaction
(c) disproportionation reaction
(d) displacement reaction
Explanation :
(a) The given balanced chemical reaction is,

This reaction is a single replacement reaction or displacement in which the the more reactive element (Fe) replace the less reactive element (H).
(b) The given balanced chemical reaction is,

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or single product.
(c) The given balanced chemical reaction is,

This reaction is a disproportionation reaction in which the chemical species gets oxidized and reduced simultaneously. It is also considered as a redox reaction.
(d) The given balanced chemical reaction is,

This reaction is a single replacement reaction or displacement in which the the more reactive element (Ag) replace the less reactive element (Pt).
