First off, we can find the volume that need to be filled:
2-1.25
=0.75L
Asbthe unit is still in Litres,we need to converge it to mL.
1L = 1000mL
mL needed:
=0.75×1000
=750mL
Therefore the answer is 750mL.
Hope it helps!
3420m
Explanation:
Given parameters:
Length of path = 6200m
time taken for the horse to run = 22.5min
speed = 152meters/minute
Unknown:
Distance run by the horse = ?
Solution:
Speed is the rate of change of distance with time.
Speed = 
Distance = speed x time
Distance = 152 x 22.5 = 3420m

Answer:
the type of change in which the chemical composition of an element changes is called chemical change
the best example is the formation of H2O. Since Hydrogen is an inflammable gas and oxygen is consumed by fire to keep burning, but their product - H2O is used to extinguish oxygen
Initial volume (without silver): 25.0 mL
final volume (with silver): 54.8 mL
1 mL = 1 cm3 (you can just change the units and the numbers will be the same)
volume of silver piece:
54.8 cm3 - 25.0 cm3 = 29.8 cm3
Answer:
Explanation: A square of dry ice has a surface temperature of - 109.3 degrees Fahrenheit (- 78.5 degrees C). Dry ice additionally has the extremely decent component of sublimation - as it separates, it transforms legitimately into carbon dioxide gas as opposed to a fluid.
