A student weighs some water, sugar , and yeast then mixes them together. Some bubbles form. When the bubbling stops, the students weighs the mixtures Weight before mixing
907

Weight after mixing
851

Why is the weight after mixing less than before mixing?

A:because has formed
B:because water evaporated
C:because the sugar dissolved
D:because the yeast disappeared when mixing water

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
