Chemical reaction when chromium metal is immersed in an aqueous solution of cobalt(II)

Chemistry
1 answer:
never [62]2 years ago
8 0

The chemical equation for the reaction is 2Cr (s) + 3CoCl_2 (aq) --- > 2CrCl_3 (aq) + 3Co (s)

<h3>Chemical reaction</h3>

Chromium metal is higher in the reactivity series than cobalt. Thus, chromium will displace cobalt from solutions.

Therefore, the equation for the reaction between chromium metal and cobalt (II) chloride will be written as:

2Cr (s) + 3CoCl_2 (aq) --- > 2CrCl_3 (aq) + 3Co (s)

What is the molarity of the solution produced when 8.0g NaOH is dissolved in sufficient water to prepare 500.mL of solution?
Sindrei [870]

Answer:

Molarity = 0.4M

Explanation:

Molar mass of NaOH (M)= 40

m= 8g, V= 500ml=0.5L

n= m/M=[8/40]= 0.2mol

Applying

n= CV

0.2= C×0.5

C= 0.4M

Calculate the density of an aluminum block with a volume of 100 cm3 and a mass of 270g.
m_a_m_a [10]

Answer:

<h2>2.7 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{270}{100}  =  \frac{27}{10} \\

We have the final answer as

<h3>2.7 g/cm³</h3>

Hope this helps you
