- INTRODUCTION: In chemistry, neutralization occurs when an acid and a base react with each other. Most chemistry occurs in water (that is, is aqueous); under these circumstances, neutralization leads to water with no excess hydrogen or hydroxide ions present. Neutralization can most simply be expressed as acid + base → salt + water For example, HCl + NaOH → NaCl + H2O The stoichiometry of the reaction depends on how much hydrogen ion and hydroxide ion each reactant provides. In this case, each molecule of HCl provides one hydrogen ion, and each molecule of NaOH provides one hydroxide ion. The one hydrogen and one hydroxide ion combine to form one molecule of water. For this assignment, suppose that you have been presented with several solutions of hydrochloric acid (HCl) and some of the most popular bases for wastewater treatment: magnesium hydroxide (Mg(OH)2), calcium carbonate (CaCO3), calcium oxide (CaO), sodium bicarbonate (NaHCO3), sodium hydroxide (NaOH), and ammonia…Practical Reserach: Explain what the statement "variables are independent of each other" implies.Blood alcohol content (BAC) is a measure of how much alcohol is in someone’s blood. It is usually measured as a percentage, so a BAC of 0.3% is three-tenths of one percent. That is, there are 3 grams of alcohol for every 1,000 grams of blood. A BAC of 0.05% impairs reasoning and the ability to concentrate. A BAC of 0.30% can lead to a blackout, shortness of breath, and loss of bladder control. In most states, the legal limit for driving is a BAC of 0.08%. BAC is usually measured by a breathalyzer, urinalysis, or blood test. However, Swedish physician E. M. P. Widmark developed the following equation for estimating an individual’s BAC. This formula is widely used by forensic scientists. B = -0.015*t+(2.84*N/W*g) The variables in the formula are defined as: B = percentage of BAC N = number of “standard drinks” (N should be at least 1) (NOTE: A standard drink is one 12-ounce beer, one 5-ounce glass of wine, or one 1.5-ounce shot of distilled liquor.) W = weight in pounds g = gender…
- Part 6: Boolean Logic Expressions Boolean expressions are types of logical operations that we can perform on true and false values. Note that the word Boolean is always capitalized because it was named after its inventor, George Boole. Boolean algebra is a very important topic in computer science, and if you haven't learned it before you definitely will in the future. However, for our purposes we are only interested in how we can use them to manipulate binary numbers. The way we use them on binary numbers is by treating 1 as true and 0 as false. From this point on I will be using 0 and 1 instead of false and true. There are many types of Boolean expressions, but the three most important ones are AND, OR, and NOT. AND takes 2 operands and will output 1 if they are both 1, or 0 otherwise OR takes 2 operands and will output 1 if either one is 1, or 0 if neither is 1 NOT takes 1 operand and reverses it: 1 becomes 0, and 0 becomes 1 We can represent this behavior using something called a…Give Authentic and Relevant Answer. Software Engineering Question: The client's ultimate objective is to have an online software system that gives information about the movies that the client sells to customers online. The system gives information about movies and actors/actresses. That is, the system should be accessed online. Each movie is identified by title and year of release. A movie has a genre (drama, comedy, etc.), a running time, and one director. A movie is made at a movie studio and may have multiple producers (people in charge of the movie production). A movie studio has a unique name and address, and may make one or more movies. Producers are identified by name and date of birth and produce one or more movies. Directors are also identified by name and date of birth and direct one or more movies. Assume that directors don’t act or produce movies. Actors are identified by name and date of birth, and may appear in one or more movies. An actor who appears in a movie, has a…The total nuclear binding energy is the energy required to split a nucleus of anatom in its component parts: protons and neutrons, or, collectively, the nucleons.It describes how strongly nucleons are bound to each other. When a high amountof energy is needed to separate the nucleons, it means nucleus is very stableand the neutrons and protons are tightly bound to each other.The atomic number or proton number (symbol Z) is the number of protons foundin the nucleus of an atom. The sum of the atomic number Z and the number ofneutrons N gives the mass number A of an atom. The approximate nuclear binding energy Eb in million electron volts, of an atomicnucleus with atomic number Z and mass number A is calculated using thefollowing formula: Eb = ((a1*A) - (a2*(A**2/3)) - (a3*(Z**2/A**1/3)) - (a4*(((A-2Z)**2)/A )) + (a5/(A**1/2))) where, a1 = 15.67, a2 = 17.23, a3 = 0.75, a4 = 93.2 and a5 = 0 if A is odd Or a5 = 12 if A and Z are both even Or a5 = -12 if A is even and Z is odd The…

Mario makes all of his pizzas from 10 different ingredients, using 3 ingredients on each pizza. Mario’s cousin Luigi owns a pizzeria as well. Luigi makes all his pizzas from 9 ingredients, using 4 ingredients on each pizza. Mario and Luigi have made a bet: Mario believes that customers can order a larger selection of pizzas in his pizzeria than they can order in Luigi’s pizzeria. Use functions for this assignment. Implement a factorial() function yourself (do not use the one from the math module) When choosing k items from n possible items, the number of possibilities can be obtained using the following formula: (??)=?!?!(?−?)!(nk)=n!k!(n−k)! Make a function called choose with two parameters n and k, that implements the above formula. Write a program that calculates the number of pizzas Mario and Luigi can make. The outcome should look like this: Mario can make 120 pizzas.Luigi can make 126 pizzas. Luigi has won the bet.
