As 1 g of sodium hydroxide dissolves in 100g of water, the conductivity of the water:

2 answers:

I think the correct answer would be to increase. As salt is being dissolved in water, it dissociates into corresponding ions which would make conductivity of the solution more higher than pure water since charge particles are already present. Hope this helps.

Answer:

The conductivity of the resulting solution will increase.

Explanation:

The conductivity of the solution obtained by adding sodium hydroxide in water will increase as compared to pure water due to complete dissociation of sodium hydroxide into sodium ion and hydroxide ions. The conductivity increases on increase in number of ions in a solution.

The conductivity depends upon

a) number of ions

b) mobility of ion.

A rectangular block has the following dimensions: 3.21 dm, 5.83 cm, and 1.84 in. The block has a mass of 1.94 kg. What is the de

spin [16.1K]

The density of the rectangular block in g/mL is 7.0.

Given the following data:

Mass of block = 22.8 gra1.94 kg

Length of block = 3.21 cm

Width of block = 5.83 cm

Height of block = 1.84 in.

To find the density of the block in g/mL:

First of all, we would determine the volume of the rectangular block by using the following formula:

$Volume = length$ × $width$ × $height$

Conversion:

1 in = 2.54 cm

5.83 in = X cm

Cross-multiplying, we have:

$X = 2.54(5.83)\\\\X = 14.81 \; cm$

$Volume = 3.21$ × $5.83$ × $14.81$

Volume = 277.16 cubic centimeters.

Note: Milliliter (mL) is the same as cubic centimeters.

1000 grams = 1 kg

Y grams = 1.94 kg

Cross-multiplying, we have:

Y = 1940 grams

Now, we can find the density:

$Density = \frac{Mass}{Volume}\\\\Density = \frac{1940}{277.16}$

Density = 7.0 g/mL

Therefore, the density of the rectangular block in g/mL is 7.0.

Where do the gaseous elements tend to be located on the table

kotegsom [21]

Answer:

Group 8 or Group 0

Explanation:

Group 8 or Group 0 are generally inert gases with Helium as the first member in that group. Their complete duplet (in the case of Helium) and Octet (in the case of Neon) configuration makes them very stable and chemically un-reactive.
