Answer:
a. True
Explanation:
The statement given regarding salt is correct,
Salt is ionic in nature, as it is composed of a positive ion, i.e. , cation and a negative ion, i.e. , anion.
Salt can be made by the combination of respective acid and base.
There are three nature of salt, acid, base and neutral.
Hence, from the given statement of the question,
The correct option is a. True.
The elements present in Ammonium Nitrate are Hydrogen, Nitrogen, and Oxygen at a ratio of 4:2:3, respectively. Hydrogen weighs in at 1.008 amu, Nitrogen at 14.007, and Oxygen at 15.999. This means that the molar mass would be:
Hydrogen
4 x 1.008 = 4.032 amu
Nitrogen
2 x 14.007 = 28.014 amu
Oxygen
3 x 15.999 = 47.997 amu
Total
4.032 + 28.014 + 47.997 = 80.043 amu
The molar mass of Ammonium Nitrate is 80.043 grams per mole.
Answer:
The percent yield of chloro-ethane in the reaction is 82.98%.
Explanation:
Moles of ethane = 
Moles of chlorine gases =
As we can see that 1 mol of ethane react with 1 mole of chlorine gas.the 10 moles will require 10 mole of chlorine gas, but only 9.1549 moles of chlorine gas is present.
This means that chlorine gas is in limiting amount and amount of formation of chloro-ethane will depend upon amount of chlorine gas.
According to reaction , 1 mol of chloro ethane gives 1 mol of chloro-ethane.
Then 9.1549 moles of chlorien gas will give:
of chloro-ethane
Mass of 9.1549 moles of chloro-ethane:
9.1549 mol × 64.5 g/mol = 590.4910 g
Theoretical yield of chloro-ethane: 590.4910 g
Given experimental yield of chloro-ethane: 490.0 g
The percent yield of chloro-ethane in the reaction is 82.98%.
Answer:
ll matter is composed of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements can combine in simple whole number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.
Each atom is uniform, homogeneous, colorless, tasteless, and indivisible.ll atoms of a given element are identical in mass and properties. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atom.
Answer:
Perfectly Specified
Explanation:
Given,
Pressure = P = 0.9 atm
and the Boiling point = T
Number of phases P = 1
Number of components C = 1
According to Gibb's phase rule ,
F = C - P + 2
If
- F = 0, the system is perfectly specified
- F > 0, the system is under specified
- F < 0 the system is over specified
At P = 0.9 atm, boiling point is T i.e. Fixed equal to 96.7 °C (from steam table)
P is independent variable and T is dependent variable (depends on the value of P ).
In this case only two variables are required to fix the system pressure and temperature.
In the given problem, pressure is fixed so the temperature is also fixed. There is no requirement of any other variable.
Therefore degree of freedom,
F = 0
The system is perfectly specified.
