Answer:
Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called <u>Stereoisomers</u>.
Explanation:
Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space. It is further classified as;
i) Geometrical Isomerism:
In this class of isomerism the groups or atoms about the double bond occupies different region in space. It is also called as <em>cis-trans </em>isomerism.
ii) Optical Isomerism:
In this class the molecules having same molecular formula differ in their interaction towards plane polarized light.
Answer: When using 645 L /s of O2 in a temperature and pressure of 195°C, 0.88 atm respectively, we will get 0.355Kg /s NO
Explanation:
- First we review the equation that represents the oxidation process of the NH3 to NO.
4NH3(g) + 5O2(g) ⟶4 NO(g) +6 H2O(l)
- Second we gather the information what we are going to use in our calculations.
O2 Volume Rate = 645 L /s
Pressure = 0.88 atm
Temperature = 195°C + 273 = 468K
NO molecular weight = 30.01 g/mol
- Third, in order to calculate the amount of NO moles produced by 645L/ s of O2, we must find out, how many moles (n) are 645L O2 by using the general gas equation PV =n RT
Let´s keep in mind that using this equation our constant R is 0.08205Lxatm/Kxmol
PV =n RT
n= PV / RT
n= [ 0.88atm x 645L/s] / [ (0.08205 Lxatm/Kxmol) x 468K]
n= 14.781 moles /s of O2
-
Fourth, now by knowing the amount of moles of O2, we can use the equation to calculate how many moles of NO will be produced and then with the molecular weight, we will finally know the total mass per second .
14.781 moles /s of O2 x 4moles NO / 5 moles O2 x 30.01g NO / 1 mol NO x 1Kg NO /1000g NO = 0.355Kg /s NO
Answer: In creating a covalent bond, it would be best to bind oxygen to carbon (C ).
Covalent bonds result from electron-sharing between two atoms. One carbon atom combines with two oxygen atoms. Thus, the carbon dioxide molecule has two C=O bonds. Carbon dioxide is a very common covalent bond.
The answer is true, particles in the gaseous state are the furthest apart
