Step 1
Part A: NaOH(aq)Na+(aq)+OH(aq)
NaOH is an Arrhenius base because it produces OHions in an aqueous solution. Write an equation for this ionization reaction.
Step 2
PART B: H2SO4(aq)2H+(aq)+SO42(aq)
H2SO4 is an Arrhenius acid because it produces H+ions in an aqueous solution. Write an equation for this ionization reaction.
Step 3
PART C: HBr(aq)H+(aq)+Br(aq)
HBr is an Arrhenius acid because it produces H+ions in an aquation for this ionization reaction.
Step 4
PART D:
Sr(OH)2(aq)Sr2+(aq)+2OH(aq)
Sr(OH)2 is an Arrhenius base because it produces OH ions in an aqueous solution. Write an equation for this ionization reaction.

Answer:
(a) Base
(b) Acid
(c) Acid
(d) Base
Explanation:
According to the Arrhenius acid-base theory:
- An acid is a substance that releases H+ in aqueous solution.
- A base is a substance that releases OH in aqueous solution.
(a) NaOH is a base according to the following equation:
NaOH(aq)Na+(aq)+OH(aq)
(b) H2SO4 is an acid according to the following equation:
H2SO4(aq)2H+(aq)+SO42(aq)
(c) HBr is an acid according to the following equation:
HBr(aq)H+(aq)+Br(aq)
(d) Sr(OH)2 is a base according to the following equation:
Sr(OH)2(aq)sSr2+(aq)+2OH(aq)

Step 1
Arrhenius theory of acids and based
The Arrhenius theory of acids and bases tells that if a compound generates H+ ions in aqueous solution then it is identifies as acid whereas if it generates OH ion in aqueous solution then it is identified as a base.
Step 2
1. In water, NaOH dissociate into Na+ and OH ions. Since NaOH(aq) is identified as Arrhenius base.
NaOH(aq)Na+(aq)+OH(aq)
Step 3
2. In water, H2SO4 dissociate into H+ and SO42 ions. Since H2SO4 generates H+ ion into the aqueous solution therefore, H2SO4(aq) is identified as Arrhenius acid.
H2SO4(aq)2H+(aq)+SO42(aq)
Step 4
3. In water, HBr dissociate into H+ and Br ions. Since HBr generates H+ ion into the aqueous solution therefore, HBr(aq) is identified as Arrhenius acid.
HBr(aq)H+(aq)+Br(aq)
Step 5
4. In water, Sr(OH)2 dissociate into Sr2+ and OH ions. Since Sr(OH)2 generates OH ion into the aqueous solution therefore, Sr(OH)2(aq) is identified as Arrhenius base.
Sr(OH)2(aq)Sr2+(aq)+2OH(aq)

Jones figures that the total number of thousands of miles that a used auto can be driven before it would need to be junked is an exponential random variable with parameter 120.
Smith has a used car that he claims has been driven only 10,000 miles.
If Jones purchases the car, what is the probability that she would get at least 20,000 additional miles out of it?
Repeat under the assumption that the lifetime mileage of the car is not exponentially distributed but rather is (in thousands of miles) uniformly distributed over (0, 40).

In this problem, you will prove the sin and cos sum formulas in two ways.
sin(a+b)=sinacosb+cosasinb
cos(a+b)=cosacosbsinasinb
Use Euler’s formula: eia=cosa+isina to prove the formulas.
Use the rotation matrix Rθ from last term and the fact that the matrix of a com- position of two linear transformations is the product of their respective matrices. (therefore RθRv=Rθ+v)
