At 700 K acetaldehyde decomposes in the gas phase to methane and carbon monoxide. The reaction is:
CH3CHO(g)→CH4(g)+CO(g)
A sample of CH3CHO is heated to 700 K and the pressure is measured as 0.43 atm before any reaction takes place. The kinetics of the reaction are then followed by measurements of total pressure and these data are obtained:

Question:

Find total pressure after 1.39×10⁴ s .

************CODING IN C++ ONLY ********************

Instructions

Write a function, remove, that takes three parameters: an array of integers, the number of elements in the array, and an integer (say, removeItem).

The function should find and delete the first occurrence of removeItem in the array. (Note that after deleting the element, the number of elements in the array is reduced by 1.) Assume that the array is unsorted. Also, write a program to test the function.

Your program should prompt the user to enter 10 digits for the array. Display the starting array to the user and prompt them to select an integer to remove. After the selected integer has been removed, the updated list should be displayed to the user. If the value does not exist or the array is empty, output the following message: x is not in the list

GRADING CRITERIA

1)  Defined the remove function

2) Removing elements from the list

3) List does not contain integer to be removed

You are planning to save for retirement over the next 20 years. To do this, you will invest $900 a month in a stock account and $600 a month in a bond account. The return of the stock account is expected to be 9 percent, and the bond account will pay 5 percent. When you retire, you will combine your money into an account with a return of 7 percent.

How much can you withdraw each month from your account assuming a 20-year withdrawal period?

Suppose astronomers were to discover a new comet at an aphelion of 40.0 AU, with a transverse velocity of v₀= 941 m/s

What

The neo-classical growth model emphasizes two determinants of intensive growth (ie. growth in output per person).  Write a concise essay in which you explain the operation of the neo-classical growth model and the role played by the two key determinants of growth within the model.

Halley's comet, which passes around the Sun every 76 years, has an elliptical orbit. When closest to the Sun (perihelion) it is at a distance of 8.823

1. Treatment with which of the following in neonatal (newborn) male rats would most likely lead to normal defeminization and masculinization of sexual behavior? (Assume that in adulthood all males are treated with testosterone and tested with a female.)

-Androgen receptor antagonist

-Estrogen receptor antagonist

-Alpha-fetoprotein inhibitor

-Aromatase inhibitor

-Castration

2. Phoenix et al.’s 1959 paper showed for the first time that...

-Androgen exposure during early life affects sexual behavior in adulthood.

-Estrogen exposure during early life affects sexual behavior in adulthood.

-Androgen exposure during adulthood affects sexual behavior in adulthood.

-Estrogen exposure during adulthood affects sexual behavior in adulthood.

-Pregnant females treated with androgens produce hermaphroditic offspring.

3. Which of the following is true of organizational effects on the brain in both rats and primates?

-Sexual differentiation of the brain mostly occurs before birth.

-Masculinization of the brain requires the presence of gonadal steroids.

-Feminization of the brain requires the presence of gonadal steroids.

- Masculinization of the brain requires aromatization of androgens to estrogens.
