Which formula can be used to calculate the molar mass of ammonia

Chemistry
1 answer:
Nikolay [14]3 years ago
7 0

Answer:

Since there are 3 Hydrogen atoms present, the formula mass of H is 1.0 × 3 = 3.0 g/mol. Therefore, by adding them up, the formula mass of ammonia is: [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.

You were making a cream based sauce for your pasta and decided to add some freshly canned tomatoes to the sauce. It tasted fine,
soldier1979 [14.2K]

Answer & explanation:

Canned fruits and vegetables generally have a high acidity and salinity content, in order to prevent the product from spoiling, in addition to enhancing its flavor.

The cream-based sauce started to curdle due to the acidity present in the canned tomatoes.

By lowering the pH of dairy products, a protein in them called casein begins to clot. It is this clotting of the casein that causes the cream-based sauce to curdle.

Over the course of two years the top layer of soil at a Michigan farm is blown away
Colt1911 [192]

For each of the situations below, state whether it describes erosion, weathering, or possibly both.

Answer:

Erosion

Explanation:

The blowing away of the top layer of the soil at a Michigan farm is best described as scenario that shows wind erosion.

Erosion is the removal of the top layer of the earth on which plant grows. In short is the washing away of soil by stream or blowing away by wind.

When soil is blow away, it is a pure case of erosion. The process of erosion usually follows weathering or sometime occurs together with it.

Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Often times, the process of weathering and erosion occurs together. It is loose weathering products that are carried away during erosion.

In the soil layer at Michigan, the process of erosion by wind is current taking place by ablation.

It takes to break an iodine-iodine single bond. Calculate the maximum wavelength of light for which an iodine-iodine single bond
Zolol [24]

The given question is incomplete. The complete question is :

It takes 151 kJ/mol to break an iodine-iodine single bond. Calculate the maximum wavelength of light for which an iodine-iodine single bond could be broken by absorbing a single photon. Be sure your answer has the correct number of significant digits.

Answer:  793 nm

Explanation:

The relation between energy and wavelength of light is given by Planck's equation, which is:

E=\frac{hc}{\lambda}

where,

E = energy of the light  = 151 kJ= 151000 J   (1kJ=1000J)

N= moles = 1 = 6.023\times 10^{23}

h = Planck's constant  = 6.626\times 10^{-34}Js

c = speed of light  = 3\times 10^8m/s

\lambda = wavelength of light  = ?

Putting in the values:

151000J=\frac{6.023\times 10^{23}\times 6.626\times 10^{-34}Js\times 3\times 10^8m/s}{\lambda}

{\lambda}=7.93\times 10^{-7}m=793nm    1m=10^{-9}nm

Thus  the maximum wavelength of light for which an iodine-iodine single bond could be broken by absorbing a single photon is 793 nm
