Put this equation into word form.

Answer:

Led is a light-emitting diode, a semiconductor diode that glows when a voltage is applied. So, there is always a sure result of whether a substance conducts electricity or not as the light glows. That is why it is a better option for testing conduction of electricity.

The balanced chemical equation of decomposition of silver oxide is 2 Ag₂O -> 4 Ag + O₂.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:

A. Florine has a stronger pull than Magnesium

Explanation:

Electronegativity refers to the tendency in which an tom would attract electrons to itself.

Below each element in the periodic table is their electronegativity value. Florine has the highest electronegativity value of 4.0.

Going through options;

A. Florine has a stronger pull than Magnesium

Florine = 4.0

Magnesium = 1.2

This correct

B. Hydrogen has a stronger pull than Phosphorus

Hydrogen = 2.1

Phosphorus = 2.1

This is wrong

C. Potassium has a stronger pull than Sodium

Potassium = 0.8

Sodium = 0.9

This is wrong

D. Iron has a stronger pull than Bromine

Iron = 1.8

Bromine = 2.8

This is wrong

The question is incomplete. The complete question is :

A worker paints a 5.2 foot wide crosswalk on a street her boss tells her to make crosswalk 1.25 feet wider. How wide is the finished crossroad ?

Solution :

It is given that the worker paints a crossroad on a street whose width is = 5.2 feet.

The boss of the worker asks the worker to make the width of the cross road 1.25 feet more wider.

Thus the required width of the cross road is = 5.2 feet + 1.25 feet

                                                                         = 6.45 feet.

Therefore the finished cross road is = 6.45 feet wide.

Answer:

Drinking water can be produced from waste water and from lakes but the difference is in the difficulty of producing water which we can consume.

Drinking water should be clean and toxic free so that if does not affect the human body. Waste water carry more toxic matter in comparison to lake water that's why, producing drinking water from waste water takes more time, expensive and difficult.

So, producing drinking water from waste water is more difficult as it require the removal of more toxic matter than water in lakes.

On TV, they always seem pretty confident in what they are doing, but it never shows the training and how much work you have to go through to get to the end result. They always just take their time walking around and do lots of talking in TV shows when that's not the case at all in this video. It's get in and get out with as much evidence as possible. The TV show always has a successful ending when the hour ends, which is not the case in real life.

Answer:

116g/mol

Explanation:

Mg=24

NO2=46

multiple 46 by 2and then add 24

The molar mass of  Mg(NO₂)₂ is  116.33 g/mol.

To calculate the molar mass of Mg(NO2)2, we need to determine the atomic masses of each element in the compound and multiply them by their respective subscripts.

The atomic masses of the elements involved are:

Mg (magnesium) = 24.31 g/mol

N (nitrogen) = 14.01 g/mol

O (oxygen) = 16.00 g/mol

The compound Mg(NO₂)₂ contains one magnesium atom (Mg), two nitrate ions (NO₂), and each nitrate ion contains one nitrogen atom (N) and two oxygen atoms (O).

Molar mass of Mg(NO₂)₂ :

Mg: 1 × 24.31 g/mol = 24.31 g/mol

N: 2 × 14.01 g/mol = 28.02 g/mol

O: 4 × 16.00 g/mol = 64.00 g/mol

Now, add up the individual masses:

24.31 g/mol + 28.02 g/mol + 64.00 g/mol = 116.33 g/mol

Therefore, the molar mass of Mg(NO₂)₂  is 116.33 g/mol.
