Which one of the following is smallest in size?

N3- O2- F- Na

Answers

F- is the smallest because it accepts 1 electron 2 make its atomic number 10 making it have jst 2 orbitals but O²-,N³- and Na have their atomic number to be 18,17 and 11 respectively with 3 orbitals..
hope this helps *winks*

F- is the smallest. Na is largest, so that would not be correct 100%

Magnetism is believed to be caused by the alignment of small, numerous sub-units called _____. poles fields ions domains

Answers

Magnetism is believed to be caused by the alignment of small, numerous sub-units called domains. A magnetic domain is a small portion in the magnetic fields of atoms that have grouped together and aligned uniformly. To best describe domains, they are often likened to tiny random magnets pointing at different directions within a material. When the material is magnetized, these tiny magnets align and point towards a unified direction.

the answer is domains.................

2. A sample of iron has the dimensions of 2.0 cm x 3.0 cm x2.0 cm. It has a mass of 94.0 grams. What is the density of
iron? (8 points)

How many moles of sodium hydroxide are contained in 65.0 mL of a 2.20 M solution?

Answers

2.20 M means there are 2,20 mol of NaOH in 1 000 mL of solution. We can use this proportion as a conversion factor:

$65\ mL\cdot (2.20\ mol)/(1\ 000\ mL) = \bf 0.143\ mol$

Please answer immediatelyHow many grams of glucose, C6H12O6, are needed to make 100 mL of a 1.5 M solution?

Answers

THE ANSWER BOI:

27 g

HERE IS DA EXPLANATION FAM:

27 g

M(C6H12O6) = 6*12 + 12*1 + 6*16 = 180 g/mol

100 mL = 0.1 L solution

1.5 M = 1.5 mol/L

1.5 mol/L * 0.1 L = 0.15 mol C6H12O6

0.15 mol * 180 g/1 mol = 27 g C6H12O6

Final answer:

To find the needed grams of glucose for a 1.5 M solution in 100ml, you multiply the molarity by the molecular weight of glucose and the volume of the solution. The calculation is 1.5 mol/l * 180 g/mol * 0.1 l = 27 grams. Therefore, 27 grams of glucose is needed.

Explanation:

The problem in question requires you to make use of the formula M= mass (mol)/ Volume (L). To find the required grams of glucose, C6H12O6, for a 1.5 M solution in 100mL, you would multiply the molarity with the molecular weight of glucose - approximately 180g per mole - and the volume of the solution - 0.1L. Therefore, to solve the problem you would calculate it as: 1.5 mol/l X 180 g/mol x 0.1 l which equals 27g. Hence, you need 27 grams of glucose to make a 100ml, 1.5M solution.
