Write the molecular, total ionic, and net ionic equations for this reaction

For the molecular equation i got:

Pb(NO3)2 (aq) + MgI2 (aq) -> PbI2 (aq) + Mg(NO3)2 (s)

this is wrong and i'm very confused

1. Ca(ClO3)2

2. CsBr

3. AlCl3

4. Cs2SO3

5.

I got 60%, but this seems too simple. Is my answer correct??

55% are men, and 40% of those taking a car are men.

a. If an employed adult from this suburb is chosen at random, what is the probability that the person is a woman?

b. If a woman is chosen at random from this suburb, what is the probability that she takes the train to work?

I made a contingency table and got these answers:

a: 51/100

b: 27/51

Are these correct??

i'm probably going to get a C in my AP physics class which will be the lowest grade I've ever received in a class. I have a 4.1 weighted GPA and am taking weighted classes. I'm an A/B student

(mainly A's). Should I drop physics and escape the C or stick with it? How much will this affect my chances of getting into college?

Which majore electrolyte most notably follows water in/out of the plasma?

a. Na

b. K

c. Ca

d. HCO3

i thought it was sodium, but water follows sodium, not the other way around. I'm torn between a and b.

How good are the traditional BSN programs at JMU, VCU and GMU? Which one is the best?

problem: xe^x+e^x=0

i'm supposed to factor out a GCF

so i get

e^x(x+1)=0

/(x+1) /(x+1)

e^x=0

x=ln0

no solution

i think this is wrong..

H(t) = 93(0.91)^t+68

What is the asymptote of the graph of H(t)?

Here's the problem: 3^(x+2)=5^x

how do you solve this??

i got

ln3^(x+2)=ln5^x

(x+2)ln3=xln5

2ln3+xln3=xln5

-xln3 -xln3

ln9=xln5-xln3

ln9=x(ln5-ln3)

ln9=x(ln5+ln(1/3))

ln9=x(ln(5 1/3))

x=ln9/ln(5 1/3)

but I feel like this is wrong..

what's the inverse of

y = sqrt (x+2) - 3

I'm struggling with this question:

Suppose two boxes on a frictionless table are connected by a heavy cord of mass 1.0 kg. Calculate the acceleration (magnitude) of each box and the tension (magnitude) at each end of the cored, using the free-body diagrams shown in Figure 4-53. Assume FP = 42.0 N, ma = 9.0 kg, and mb = 13.5 kg, and ignore sagging of the cord. Compare your results to Example 4-12 and Figure 4-22.

find:

mA acceleration in m/s2

mB acceleration in m/s 2

FTA in Newtons

FTB in Newtons
