Normal = <span>hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional
</span><span>Reverse faults = form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together.

Molarity=moles/liters. Take 42.9 g CaCl2 and divide it by the molar mass of CaCl2 which is 110.98. You get .387 moles. Finally divide .387 moles/ 45 L = .0086 M CaCl2
Answer: a) pH of a 0.1 M vinegar solution is 2.9
b) It is an acid as pH is less than 7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.
As vinegar is a weak acid, its dissociation is represented as;
cM 0 0
So dissociation constant will be:
Give c= 0.1 M
Also
Thus pH of a 0.1 M vinegar solution is 2.9
As pH is less than 7, it is an acid.
Answer: <u>Mixtures can be physically separated but pure substances cannot be physically separated.</u>
Explanation: Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography. A pure substance, any compound or element, can't be separated into different atoms by physical methods. Pure substances are compounds and elements (made up of the same atom or same molecule respectively), while mixtures are an assortment of different substances put together. Hope this helps ^-^.
