Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
In order for you to get the answer, please have in mind the following situation: To increase the molar concentration of N2O4(g), 2NO2(g) should also increase for equilibrium to occur. Now, this equation is exothermic. By <span>Le Chatelier's principle, equilibrium constant and reaction constants also come into play in terms of increasing or decreasing the temperature. After that I know you can find the answer. </span>
Answer:
Cell membranes (plasma membranes) help organisms maintain homeostasis by controlling what substances may enter or leave cells.
Answer:
Explanation:
Molarity is found by dividing the moles of solute by liters of solution.
We are given grams of a compound and milliliters of solution, so we must make 2 conversions.
1. Gram to Moles
We must use the molar mass. First, use the Periodic Table to find the molar masses of the individual elements.
- C: 12.011 g/mol
- H: 1.008 g/mol
- O: 15.999 g/mol
Next, look at the formula and note the subscripts. This tells us the number of atoms in 1 molecule. We multiply the molar mass of each element by its subscript.
6(12.011)+12(1.008)+6(15.999)=180.156 g/mol
Use this number as a ratio.
Multiply by the given number of grams.
Flip the fraction and divide.
2. Milliliters to Liters
There are 1000 milliliters in 1 liter.
Multiply by 2500 mL.
3. Calculate Molarity
Finally, divide the moles by the liters.
The original measurement has 2 significant figures, so our answer must have the same. That is the hundredth place and the 3 tells us to leave the 7.
1 mole per liter is also equal to 1 M.

<h2><u>
FAMILY:</u></h2>
Family is defined as a specific group of people that may be made up of partners, children, parents, aunts, uncles, cousins and grandparents. An example of a family is a set of parents living with their children. The definition of family is the group of people who share common ancestors.
