Explanation:
The scientific notation:
where
and k is integer.
We have the example:
You can write the numbers in a "normal" form:
Make the sum:
And next write it in the scientific notation:
<h3>Other method:</h3>
You can add numbers in scientific notation if the power of tens in both number is the same.
Therefore you must convert the first number:
Now, you can make the sum:
Answer:
-24.76 kJ/g; -601.8 kJ/mol
Explanation:
There are two heat flows in this experiment.
Heat from reaction + heat absorbed by calorimeter = 0
q1 + q2 = 0
mΔH + CΔT = 0
Data:
m = 0.1375 g
C = 3024 J/°C
ΔT = 1.126 °C
Calculations:
0.1375ΔH + 3024 × 1.126 = 0
0.1375ΔH + 3405 = 0
0.1375ΔH = -3405
ΔH = -24 760 J/g = -24.76 kJ/g
ΔH = -24.76 kJ/g ×24.30 g/mol = -601.8 kJ/mol
Answer: the correct option is A ( The spotted coat is an INHERITED TRAIT, and the ability to perform tricks is a LEARNED TRAIT.
Explanation:
Dog is one of the first domesticated animal by man because it has the ability to perceive information and retain it as knowledge for applying to solve problems.
Therefore, the ability to perform tricks is a LEARNED TRAIT. This is so because they have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors.
INHERITED TRAIT is a trait that can be passed down from one generation to another which are found in genes within the strands of dogs DNA. Some of the inheritable traits includes the following:
- coat color,
- ear type, and.
- tail style.
Therefore the spotted coat is an INHERITED TRAIT
