Reaction 1 : Make Ammonia

N₂+3H₂⇒2NH₃

molecules left : 1+3=4

molecules right :2

Reaction 2 : Separate Water

2H₂O⇒2H₂+O₂

molecules left : 2

molecules right :2+1=3

Reaction 3 : Combust Methane

A solution of h2so4(aq) with a molal concentration of 2.24 m has a density of 1.135 g/ml. what is the molar concentration of thi

OLga [1]

This problem is simply converting the concentration from molality to molarity. Molality has units of mol solute/kg solvent, while molarity has units of mol solute/L solution.

2.24 mol H2SO4/kg H2O * (0.25806 kg H2SO4/mol H2SO4) = 0.578 kg H2SO4/kg H2O

That means the solution weighs a total of 1 kg + 0.578 kg = 1.578 kg. Then, convert it to liters using the density data:

1.578 kg * (1000g / 1kg) * (1 mL/1.135 g) = 1390 mL or 1.39 L.

Hence, the molarity is

2.24/1.39 = 1.61 M

Some patterns of electron configuration are listed below. In each case, [G] stands for a noble-gas core and n, m, or o stand for

Nonamiya [84]

Answer:

G]ns^2np^5 group 17 (p-block)

G]ns^2np^2 group 14 (p-block)

G]ns^2mf^14 group 16 (f-block)

Explanation:

The outermost electronic configuration of an element shows the group to which it belongs in the periodic table as shown above in the answer. In addition, to that, we can be able to know from its electronic configuration, whether the element is a metal or not.

For instance;

G]ns^2mf^14 is a rare earth metal, G]ns^2np^2 group 14 is a metalloid while G]ns^2np^5 group 17 is a nonmetal.

Someone plss help me!!!

NikAS [45]

Answer:

d. Cl2

sorry if I'm wrong

Cl2, as shown in the picture should have electrons in both the atoms but, in the question, the electrons are only in one of the atoms.

hope it helps :)
