The formula of a compound is $Ni(NO_3)_2$

Given:

The ions $Ni^{2+}$ and $NO_3^-$

To find:

The formula for ions $Ni^{2+}$ and $NO_3^-$

Solution:

The ion with a positive charge (cation) = nickel ion = $Ni^{2+}$

The ion with a negative charge (anion) = nitrate ion = $NO_3^-$

Valency on nickel ion = 2

Valency on nitrate ion = 1

Using the criss-cross method as shown in image

The formula of a compound : $Ni(NO_3)_2$

The name of a compound is nickel(II) nitrate

$Ni^{2+}+2NO_3^-\rightarrow Ni(NO_3)_2$

The formula of a compound is $Ni(NO_3)_2$

How do you represent a shared pair of electrons when drawing the Lewis structure of a covalent bond

nataly862011 [7]

Answer: Each pair of shared electrons is a covalent bond which can be represented by a dash.

Explanation:

In a Lewis dot structure, the central atom can share electrons through bonds with the surrounding atoms, and this can look like a dash between the atoms.

PLEASE HELP!! Tell me the IUPAC name of the following compounds:

leonid [27]

The IUPAC rules are

a) Find out the longest chain of carbon in the given organic compound

b) We will name the longest chain.

c) We will identify the main functional group and will assign a suffix to the compound.

d) We will number the carbons in the longest chain selected so that the attached groups attain lowest numeral as substituent

e) We will name the side groups or chains.

soldi70 [24.7K]

Answer:

The elastic potential energy stored in the stretched rubber band changes to kinetic energy.

Explanation:

Joshua hooks a rubber band between his thumb and forefinger. He moves his fingers apart, stretching the rubber band---- Here potential Energy is stored which is an energy that the rubber band has because of its position and it's potential to be converted into kinetic energy.

With a quick, sudden motion, he bends his thumb forward so that the rubber band slips off----The elastic potential energy stored in the stretched rubber band will change to kinetic energy, which is the Energy in Motion and work needed to accelerate the rubber band from rest to its stated or new position.

A 800N mountain climber scales a 160m cliff. How much work is done by the mountain climber?

Fittoniya [83]

Answer:

Work done, W = 128 kJ

Explanation:

Given that,

Weight of a mountain climber, F = 800 N

It climbs to a cliff that is 160 m high.

We need to find the work done by the mountain climber. The work done by an object is given by the formula as follows :

W = Fd

Put the values of F and d.

W = 800 N × 160 m

W = 128000 J

W = 128 kJ

So, 128 kJ of work is done by the mountain climber.
