Answer:
Molarity = 1.28
Explanation:
![m= n/v](https://tex.z-dn.net/?f=m%3D%20n%2Fv)
M = molar concentration
n = moles of solute
v = liters of solution
Molarity = moles of solute / litres of solution.

Answer:
Stress changes everything.
Explanation:
Stress can make people, animals, solids, liquids, gases, plasma and even solutions shift due to friction, anger, hatred and more.
Answer:
No, the pH scale can not be utilized for all types of acids known
Explanation:
The pH scale is a scale that shows the degree of acidity or alkalinity of a substance. The pH scale is graduated from 0-14. The pH scale is mostly applied to Arrhenius acids. Recall that in the Arrhenius definition, an acid produces hydrogen ion in solution while a base produces hydroxide ion in solution. Hence we could easily measure or calculate the pH and pOH of Arrhenius acids. Arrhenius acids apply mostly to acid-base discussion in Aqueous media.
Beyond aqueous media, we can still apply the Brownstead-Lowry and Lewis definitions for acid and base. Some of these substances to which we apply these other definitions of acid and base do not necessarily contain hydrogen or hydroxide ions hence the pH scale can not be utilized in discussing their acid-base properties, hence the answer.
The monomers that react together to form polyurethane polymer are diisocyanate and diol.
<h3>
What are polymers?</h3>
- Polymers are a class of natural or synthetic substances
- It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
- Cellulose and resins are examples of natural polymers
- Polyethylene and polychloroprene are examples of synthetic polymers.
Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:

Answer: A. an electron
<u>Beta particles are electrons or positrons (electrons with positive electric charge or antielectrons).</u> Beta decay is a type of radioactive decay in which a beta ray is emitted from an atomic nucleus.
<u>Beta decay occurs when, in an unstable nucleus with too many protons or too many neutrons, one of the protons or neutrons transforms into the other.</u> In beta minus decay, a neutron is broken down into a proton, an electron, and an antineutrino (the neutrino antiparticle, meaning it has an opposite charge to the neutrino). In beta decay plus, a prototype breaks down into a neutron, a positron and a neutrino.
