<span>Dominos are similar in that the movement of one domino causes others to fall, which is a chain reaction. The problem with dominos is that one domino usually causes one other domino to fall which is a linear chain reaction (unless the dominos are set to knock over more dominos as in a fan shape). In nuclear fission of Uranium the reaction is an exponential growth chain reaction. The fission of one atom of U235 releases two or three neutrons which can cause other atoms to split which each release 2-3 neutrons and so on. In this way one split causes 3 splits which cause 9 splits which cause 27 splits and so on. A better analogy is shown in the video where the mousetrap releases 2 balls which set off 2 traps which set off 4 traps.</span>

Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic

Answer:
0.0734 grams LiOH
Explanation:
The molarity formula looks like this:
Molarity (M) = moles / volume (L)
You are given the molarity and volume (in mL). Therefore, you can plug these values into the equation and solve for moles (after you convert from mL to L).
25 mL / 1,000 = 0.025 L
0.125 M = moles / 0.025 L
(0.125 M) x (0.025 L) = moles
0.003125 = moles
After using the molarity formula, we know that 0.003125 moles LiOH are needed to satisfy these conditions. Now, we can convert this to grams using the molar mass of LiOH. This can be determined using the values from the periodic table. Remember to write your conversion in a way that allows for the units to cancel out.
Molar Mass (LiOH) = 6.941 g/mol + 16.00 g/mol + 1.008 g/mol
Molar Mass (LiOH) = 23.499 g/mol
0.003125 moles 23.499 g
------------------------ x ------------------- = 0.0734 grams LiOH
1 mole
Answer:
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
