Answer:
The correct option is;
a) The resulting mixture was cloudy
Explanation:
Here we have the initial color as
1. Colorless and
2. Dark blue
We analyze each of the results as follows
a) The resulting mixture was cloudy
A cloudy mixture forming when the two liquids are mixed is most likely due to the formation of a suspension from a new substance That is a new compound is formed
b) The total volume of the mixture was equal to the sum of the initial volumes.
Here since there is no change in the physical properties as the volume of the mixture is the sum of the volumes of the constituent then there is unlikely to be a chemical change
c) The resulting liquid was light blue
Here, the observation is more of a physical change
d) The liquids formed two separate layers in the beaker.
This is an indication that there was no mixing of the liquids hence no reaction or chemical change.
The answer is A because water can only evaporate if a liquid substances becomes gas , in this case it’s the water. When water is heated it evaporates. The molecule moves and vibrates so quickly that they can move to the atmosphere
A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups. In building a tree, we organize species into nested groups based on shared derived traits (traits different from those of the group's ancestor).
3600 years.
Since 65% of the carbon-14 is remaining, we need to get the logarithm to base 2 of 0.65 to determine how many half lives have expired. So: log(0.65)/log(2) = -0.187086643/0.301029996 = -0.621488377
So we know that 0.621488377 half-lives has gone by to the bone sample. Now we just need to multiply by the half-life of carbon-14 which is 5730 years. So: 0.621488377 * 5730 = 3561.128399 years. Rounding to the nearest 100 years gives us 3600 years.
Answer:
ATOMIC MASS = Protons + Neutrons
34+43 = 77
Atomic Mass is 77
