C) powdered sugar in hot water because the sugar is already broken so it would be more faster than sugar cube in hot water
Answer:
Explanation:
according to the balance chemical equation
2 moles of c6h14 give us 14 moles of H2O
now mass(in gram) of 2 moles of C6H14 is
moles=mass/molar mass
mass=molar mass*moles
molar mass of C6H14 is 86 therefore
mass=86*2=172
now mass of 14 moles of water is
mass=molar mass*moles
molar mass of water is 18
mass=18*14=252
from the above calculations we conclude that
172 grams of C6H14 produce 252 grams of water
so 1.28 grams of C6H14 produce =252*1.28/172=1.87 grams of water
result is that 1.28 grams of C6H14 produced 1.87 grams of water
Answer:
Modern recorders are most commonly pitched at A=440 Hz, but among serious amateurs and professionals, other pitch standards are often found. For the performance of baroque music, A=415 Hz is the de facto standard, while pre-Baroque music is often performed at A=440 Hz or A=466 Hz.
Explanation:
Answer:
that looks pretty and also well NGC 1427A has no general shape, so it is an irregular galaxy. U has a bulge in the center and arms, so it is a spiral galaxy. They are similar in the both certain plenty of dust and gas. Both also have active star-forming sites.
Answer:
b=200
l=100
Explanation:
so since it is a square all sides would be equal
when you cut the square vertically the dimensions will change
the bredth would be same that is 200
but the length would be half that is 100
