How many moles of ions would you expect in an aqueous solution containing one mole of chromium(III) chloride? Hint: write out th

Cerrena [4.2K]

Answer:

Four

Explanation:

AlCl₃(aq) ⟶ Al³⁺(aq) + 3Cl⁻(aq)

One mole of AlCl₃ produces 1 mol of Al³⁺ and 3 mol of Cl⁻.

That's four moles of ions.

Which dosage form is a semisolid preparation that contains very small solid particles that are suspended in a liquid

ivolga24 [154]

A GEL is a semisolid preparation that contains very small solid particles that are suspended in a liquid. A gel always contains an agent (e.g., agarose) that provides stiffness to the preparation.

A gel is a semisolid preparation that contains a gelling agent which provides stiffness to the preparation.

The gelling agent can be, for example, agarose (this gelling agent is used to prepare gels in electrophoresis).

In an agarose gel, agarose molecules are organized into three-dimensional (3D) structures similar to pores, which allow the passage of DNA fragments during electrophoresis.

Si Units Worksheet. Use si units to complete

Keith_Richards [23]

$\\ \bull\tt\dashrightarrow 2000m=2km$

$\\ \bull\tt\dashrightarrow 9000mL=9L$

$\\ \bull\tt\dashrightarrow 6L=6000mL$

$\\ \bull\tt\dashrightarrow 6cm=60mm$

$\\ \bull\tt\dashrightarrow 1000m=1km$

$\\ \bull\tt\dashrightarrow 50mm=5cm$

$\\ \bull\tt\dashrightarrow 4L=4000mL$

$\\ \bull\tt\dashrightarrow 10000g=10kg$

$\\ \bull\tt\dashrightarrow 10000m=10km$

$\\ \bull\tt\dashrightarrow 4000g=4kg$

$\\ \bull\tt\dashrightarrow 9km=9000m$

$\\ \bull\tt\dashrightarrow 3kg=3000g$

$\\ \bull\tt\dashrightarrow 90mm=9cm$

$\\ \bull\tt\dashrightarrow 4km=4000m$

$\\ \bull\tt\dashrightarrow 2000g=2kg$

$\\ \bull\tt\dashrightarrow 400cm=4m$

$\\ \bull\tt\dashrightarrow 3km=3000m$

$\\ \bull\tt\dashrightarrow 2cm=20mm$

$\\ \bull\tt\dashrightarrow 9000g=9kg$

Which metal is more active than NI and less active than Zn?

Mademuasel [1]

Answer : The correct option is, (2) Cr (Chromium)

Explanation :

The reactivity series of metal are arranged of the reactivity from the highest to the lowest. Reactivity series is used to determine the products of the single displacement reactions. In the single displacement reaction, the most reactive metal displaces the least reactive metal.

From the given reactivity series we conclude that there are two metal (Mg and Cr) are more reactive metal than the Ni and there are two metal (Pb and Cr) are less reactive metal than the Zn. So, the Cr (Chromium) is the metal which is more active than Ni and less active than Zn.

Hence, the correct option is, (2) Cr
