The log of the hydronium ion concentration
Answer:
O B. Convert the 10 g of NaCl to moles of NaCl.
Explanation:
The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.
(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl
58.44 is the molar mass of NaCl
m=0.1711 mol NaCl/2 kg H2O
m=0.085557837
Answer:
50/36 = 25/18
Explanation:
Solution at attachment box
Molality = mole of dissolvable (this question glucose) / kg of water
Answer:
gas, liquid, solid
Explanation:
As you go from gas to solid, the atoms get closer together and the kinetic energy decreases.
Answer:
E. Fracking
Explanation:
The process involves the high-pressure injection of 'fracking fluid' into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.
