Answer:

Group 2

Explanation:

Group 12 and 13 is incorrect because they're are most likely to gain electrons making it a negative ion. even if it loses electrons it will most likely lose more than one or two. Group 1 is incorrect because it can not form a +2 ion because it has only one electron to begin with. Therefore group 2 is correct.

according to newton’s 3rd law of motion , the strength of a reaction is _____ the strength of the action force
aleksley [76]

Answer:

Equal

Explanation:

According to Newton's third law of motion, the strength of a reaction is equal and opposite to the strength of the action force.

  • Newton's third law of motion states that "action and reaction forces are equal in magnitude but opposite in direction".
  • Therefore, if an object exerts a force of magnitude KN on a body.
  • The body will in return exert the same amount of force back on the object.
  • The law gives us an idea that force is paired in their action.

This is mind numbing, but I got you.

3NaOH + 1FeCl<em>3</em> = 1Fe(OH)<em>3 </em>+ 3NaCl

3Mg + 2H<em>3</em>(PO)<em>4</em> = 1Mg(PO<em>4</em>)<em>2</em> + 3H<em>2</em>

Determine how many gmol, kmol, and lbmols there are in 50 kilograms of n-hexane.
Artist 52 [7]

Answer: 581 gmol

0.581 kmol

1.28\times 10^{-3}lbmol

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{50\times 1000g}{86g/mol}=581mol

1. The conversion for mol to gmol

1 mol = 1 gmol

581 mol= \frac{1}{1}\times 581=581gmol

2. The conversion for mol to kmol

1 mol = 0.001 kmol

581 mol= \frac{0.001}{1}\times 581=0.581kmol

3. The conversion for mol to lbmol

1 mol = 2.2\times 10^{-3}lbmol

581 mol= \frac{2.2\times 10^{-3}}{1}\times 581=1.28\times 10^{-3}lbmol
