Sodium fluoride ionic bond

Chemistry
1 answer:
marta [7]4 years ago
6 0

Yea this makes me happy I love talking about bonds Here is a explanation since there is no question.

In the ionic bond that creates sodium fluoride, for example, the element sodium loses one of its 11 electrons to balance the 9 electrons in Fluoride because the ionization energy of sodium (the charge required to lose an electron) is low.

Glad to help

Have a wonderful day

When 2 moles of NH3(g) react with N2O(g) to form N2(g) and H2O(g) according to the following equation, 880 kJ of energy are evol
Naily [24]

Answer:

The reaction is an exothermic reaction .

The value of q is -880 kilo Joules.

Explanation:

Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system. The total enthalpy of the reaction (\Delta H) comes out to be negative.

According to reaction, 2 moles of ammonia when reacts with 3 moles of  nitrous oxide to give 4 moles of nitrogen gas and 3 moles of water vapor, along with release of 880 kJ of heat energy.

Since, heat is evolved during the course of reaction which means that reaction is an example of Exothermic reaction.

2NH_3(g)+3N_2O(g)\rightarrow 4N_2(g)+3H_2O(g),\Delta H=-880 kJ

The reaction is an exothermic reaction .

The value of q is -880 kilo Joules.

A material has an ASTM grain size number of 7. Determine the magnification, if the number of grains per square inch observed is:
Luden [163]

Answer:

A) M = 100X

B) M = 36X

C) M = 178.88X

Explanation:

Given data:

ASTM grain size number 7

a) total grain per inch^2 - 64 grain/inch^2

we know that number of grain per square inch is given as

Nm = 2^{n-1} (\frac{100}{M})^2

where M is magnification, n is grain size

therefore we have

64 = 2^{7-1}(\frac{100}{M})^2

solving for M we get

M = 100 X

B)  total grain per inch^2 = 500 grain/inch^2

we know that number of grain per square inch is given as

Nm = 2^{n-1} (\frac{100}{M})^2

where M is magnification, n is grain size

therefore we have500 = 2^{7-1}(\frac{100}{M})^2

solving for M we get

M = 36 X

C) Total grain per inch^2 = 20 grain/inch^2

we know that number of grain per square inch is given as

Nm = 2^{n-1} (\frac{100}{M})^2

where M is magnification, n is grain size

therefore we have20 = 2^{7-1}(\frac{100}{M})^2

solving for M we get

M = 178.88 X
