Answer:
1.2 × 10⁸ m
Explanation:
You want to convert metres to nanometres.
Recall that the multiplying prefix nano- means × 10⁻⁹, so
1 nm = 1 × 10⁻⁹ m
The conversion factor is either 
or 
.
You choose the one that has the desired units (nm) on top. Then
Answer:
M = 0.138 M
Explanation:
Given data:
Mass of glucose = 12.55 g
Volume of solution = 500 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of glucose:
Number of moles = mass/molar mass
Number of moles = 12.55 g/ 180.156 g/mol
Number of moles = 0.069 mol
Volume in L:
500 mL × 1 L /1000 mL
0.5 L
Molarity:
M = 0.069 mol / 0.5 L
M = 0.138 M
what is different about these two different foxes is the fox in Florida looks like he is on a diet of plants. The fox in wyoming looks like he has a squirel or some kind of animal in his mouth. Also their environment that they live in is completely different from each other hope it helps
Explanation:
Answer: Option (b) is the correct answer.
Explanation:
Chemical properties are defined as the properties which tend to chemical composition of a substance. Neutral elements with similar number of valence electrons tend to show similar chemical properties as these have same reactivity which actually affects their chemical properties.
This means that elements of the same group tend to show similar chemical properties.
For example, oxygen and sulfur atom are both group 16 elements and they have 6 valence electrons. Therefore, they show similar chemical properties.
Thus, we can conclude that a pair of O and S elements is expected to be most similar in their chemical properties.
