Answer:
linear or trigonal planar
Explanation:
The molecular formula AB have the following criteria:
A= the central atom
B= directly bonded atoms.
In Molecular Geometry, Molecular Formula AB can either be Linear or Trigonal Planar.
In linear geometry, they are formed as a result of Sp hybridised orbital. Sp hybridised orbital involves blending of one s-orbital and one p-orbital to produce a hybrid orbital directed along a straight line, therefore making it linear e.g CO , HCN etc.
In Trigonal Planar, they are formed as a result of Sp hybridised orbital. Sp hybridised orbital are formed by mixing of one s-orbital and two p-orbitals to produce orbitals which are coplanar and the lobes directed towards the corners of an equilateral triangle. (Trigonal Planar) e.g BF , , SO etc.
Answer:
1.087 mi/min
Explanation:
Given data:
Speed of car in Km/h = 105
Speed of car in miles/min = ?
Solution:
It is given that one miles = 1.61 Km
while it is known that one hour = 60 minutes
Thus in order to convert the km/h into mi/min we will divide the given value by 96.561.
105 / 96.561
1.087 mi/min
Depending on the magnitude of radiation, the effects of exposure vary too. In this case, it is assumed that the small amount of radiation here has a very high radioactivity, then definitely it can cause DNA changes. In any way, it is rare that radiation affects the lining of the lungs and can cause illnesses such as emphysema and asthma. answer is A.
Answer: Stochiometric coefficients
Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.
This is a skeletal equation and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.
