independent variable: how much bread there is
dependant variable: temperature, location, time, size.
hypothesis, the one with the bread will be way more moist than the one without.
control group: no bread at all.
experimental group: brownies with bread
constants: same tupperware, placement, time, size.
A ball slowing down as it rolls across a carpet is an example of friction.
Friction is a force that slows down moving objects.
The hydrocarbon is usually named using the prefix that would indicate or entail how many carbon are present in it. For six carbons, the name would begin with hexa-. For cyclic molecule, the name would begin further with cyclo-. Thus, for the molecule that is described above, the name would be, cyclohexane.
Another, more well-known, component is the cyclic molecule with alternating double bonds, this will be named, benzene.
Answer:
Amount of salt needed is around 2.3*10³ g
Explanation:
The salt content in sea water = 3.5 %
This implies that there is 3.5 g salt in 100 g sea water
Density of seawater = 1.03 g/ml
Volume of seawater = volume of tank = 62.5 L = 62500 ml
Therefore, the amount of seawater required is:
The amount of salt needed for the calculated amount of seawater is:
