The answer 1.60217662 x 10^-19<span />
Answer:
0.25 M
Explanation:
The first step is to determine how many moles of glucose there are, which means first finding out the molar mass of glucose. Carbon has a molar mass of about 12, hydrogen 1, and oxygen 16, so the total molar mass of glucose is about 6(12)+12(1)+6(16)=180 grams. This means that 90 grams is half a mole. Half a mole of substance divided by two liters of solution is (1/2)/2=1/4, or a molarity of 0.25. Hope this helps!
Maybe use flash cards for them to understand or look up periodic table on line and show them.
Touch can sense the texture, and you can see what color it is, but if your talking about chemical properties, I'd say smell, color, and heat can identify some chemicals.
These artificial homes preserve the resources in the animal's environment and increases population size.

Since the resources used are artificial, they are preserved with an increase in the population due to reproduction.
