Answer:
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less
Explanation:
given data
mass of aspirin = 1 g
volume of water = 450 mL
solubility of aspirin temperature = 10° C
volume of water added = 1.4 mL
to find out
how much amount aspirin would be lost
solution
we know the solubility of aspirin is
solubility of aspirin = 
solubility of aspirin = 
solubility of aspirin = 2.2 × 
g/mL
so
we can say
amount of aspirin dissolved = solubility of aspirin × volume of water added
put here value
amount of aspirin dissolved = 2.2 × × 1.4
amount of aspirin dissolved = 3.1 × g
amount of aspirin dissolved = 0.0031 g
so we can say that this is not affect % yield as amount of aspirin lost is very less

Answer:
175s
Explanation:
time it takes sunlight to reach the earth in vacuum
C=light speed=299792458m/s
X=1.5x10^8km=1.5x10^11m
c=X/t
T1=X/c
T1=1.5X10^11/299792458=500.34s
time it takes sunlight to reach the earth in water:
First we calculate the speed of light in water taking into account the refractive index
Cw=299792458m/s/1.349=222233104.5m/s
T2=1.5x10^11/222233104.5m/s=675s
additional time it would take for the light to reach the earth
ΔT=T2-T1=675-500=175s

Answer:
HELLO! I WILL EXPLAIN WHY GOLF BALLS HAVE DIMPLES.
Explanation:
DIMPLES ON A GOLF BALL CREATE A THIN BOUNDARY LAYER OF AIR THAT CLINGS TO THE BALL'S SURFACE. THIS ALLOWS THE AIR TO FOLLOW THE BALL'S SURFACE A LITTLE FARTHER AROUND THE BACKSIDE OF THE BALL, THEREBY DECREASING THE SIZE OF THE WAKE.
I AM SO SORRY ABOUT THE CAP LOCKS I THINK MY CAP LOCKS BUTTON IS PUSHED, AND IT IS NOT POPPING UP FOR SOME REASON.
ANYWAYS, HAVE A GREAT DAY!!!!!!
