Forensic science is a critical element of the criminal justice system. Forensic scientists examine and analyze evidence from crime scenes and elsewhere to develop objective findings that can assist in the investigation and prosecution of perpetrators of crime or absolve an innocent person from suspicion.

What type of reaction is BaCl2 + Na2SO4 → 2NaCl + BaSO4?

maria [59]

Answer:

Double Displacement reaction

Explanation:

BaCl2 + Na2SO4 → 2NaCl + BaSO4

Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.

What is the molar concentration of 250. mL of aqueous solution containing 48.8 g of glucose, C6H12O6?

Nezavi [6.7K]

Answer:

1.08 mol/L

Explanation:

Molarity -

Molarity of a substance , is the number of moles present in a liter of solution .

$M=\frac{n}{V}$

M = molarity ( unit = mol / L or M )

V = volume of solution in liter ( unit = L ),

n = moles of solute ( unit = mol ),

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

$n=\frac{w}{m}$

n = moles ,

w = given mass ,

m = molecular mass .

From the information of the question ,

V = 250 mL

Since ,

1 mL = 1/1000L

V = 0.250 L

w = 48.8 g

As we known , the mass of glucose ,

m = 180g/mol ,

From the above formula , moles is given as ,

$n=\frac{w}{m}$

substituting the corresponding values ,

n = 48.8g / 180g/mol

n = 0.27 mol

Now , the molarity can be calculated by using the above equation ,

M = n / V

substituting the corresponding values ,

M = 0.27 mol / 0.250 L

M = 1.08 mol/L
