Answer:

True

Explanation:

The chemical method of separating two compounds depends on their difference in solubility in water, ether, dilute acid or alkali. Separatory funnel thus, are used to distinguish immiscible fluids from their solutes. The funnel is usually made of glass, pear-shaped, and usually contains a stopper and a stopcock.

Which of the following shows three elements in order of decreasing electronegativity?
damaskus [11]

Answer:

The correct answer is option D which is the decreasing order of conductivity is Mn, O, Ge.

Explanation:

You can easily answer this if you know the periodic trends. For the property of electrical conductivity, it decreases across a period and decreases also down a group. Thus, the most conductive element must be Mn, while the least conductive one is Ge. So, the answer is: -Mn, O, Ge

A block of metal has a mass of 51.11 g and displaces 71.46 ml of water. Calculate the density of the metal in g/ml.
Damm [24]

Answer:

The answer is

<h2>0.07 g/mL</h2>

Explanation:

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

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

From the question

mass of metal = 5.11 g

volume = 71.46 mL

The density of the metal is

density =  \frac{5.11}{71.46}  \\  = 0.071508536...

We have the final answer as

<h3>0.07 g/mL</h3>

Hope this helps you
