Express the interval as an inequality in the variable x. .

Answers

Answer 1

An experimenter is studying the effects of temperature, pressure, and type of catalyst on yield from a

certain chemical reaction. Three different temperatures, four different pressures, and five different catalysts

are under consideration.

a) If any particular experimental run involves the use of a single temperature, pressure, and

catalyst, how many experimental runs are possible?

b) How many experimental runs are there that involve use of the lowest temperature and two

lowest pressures?

c) Suppose that five different experimental runs are to be made on the first day of

experimentation. If the five are randomly selected from among all the possibilities, so that any

group of five has the same probability of selection, what is the probability that a different

catalyst is used on each run?

The sum of the first ten terms of the given sequence when approximated to four decimal places is; 9.6758

What is the sum of the sequence?

We are given the formula for the sequence as;

aₙ = 1 + (⁻¹/₂)ⁿ

Thus;

First term; a₁ = 1 + (⁻¹/₂)¹ = 0.5

a₂ = 1 + (⁻¹/₂)² = 1.25

a₃ = 1 + (⁻¹/₂)³ = 0.875

a₄ = 1 + (⁻¹/₂)⁴ = 1.0625

Fifth term; a₅ = 1 + (⁻¹/₂)⁵ = 0.96875

a₆ = 1 + (⁻¹/₂)⁶ = 1.01563

a₇ = 1 + (⁻¹/₂)⁷ = 0.99219

a₈ =  1 + (⁻¹/₂)⁸ = 1.00391

a₉ = 1 + (⁻¹/₂)⁹ =  0.99805

The scientific response to this would be that water vapor condenses as it moves higher, where the atmosphere is colder, keeping this in mind, it should help to explain why rain forms more over West Farris rather than East Ferris.

Calculate the ph when 20.0 ml of 0.150 m koh is mixed with 20.0 ml of 0.300 m hbro (ka = 2.5 × 10⁻⁹)

Answers

The pH of the solution is 10.74. the pH refers to the hydrogen ion concentration. It is a measure of the acidity of the solution.

What is pH?

pH is the degree of acidity or alkalinity of a solution.

The equation of the reaction is;

KOH + HBrO ==> KBrO + H2O

The number if moles of KOH =20.0 ml x 1 L / 1000 ml x 0.150 mol/L = 0.003 moles KOH

The number of moles of HBrO = 20.0 ml x 1 L / 1000 ml x 0.300 mol/L = 0.006 moles HBrO

Since the reaction is 1:2;

[BrO-] = 0.003 mols / 0.04L = 0.075M

Now the pH, is obtained from;

KBrO + H2O ==> KOH + HBrO

BrO- + H2O ==> HBrO + OH-  

Kb of BrO- = 1x10-14 / 2.5x10-9 = 4x10-6

Kb = 4x10-6 = [HBrO][OH-] / [BrO-]

From the ICE table;

4x10^-6 = (x)^2 / 0.075

x = 5.48x10-4 M = [OH-]

pOH = -log 5.48x10-4 M = 3.26
