lol well

i might be wrong

but

#1 is chlorine
#2 is boron (not sure if energy level means filled but i don't think it does) boron is 1s2 2s2 2p1 so it should be it
#3 i'm pretty sure is helium
#4 Hydrogen unless metalloids count
#5 i'm sorry but balancing equations is a joke if you can't do them you fail on life

2Ch4 + 4O2 ---> 2 Co2 + 4H2O

what do you think?

...wow

well 2 and 3 are wrong

2H2(g) + O2(g) --> 2H2O(l)
CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g)

ok i can't even read what i wrote

2(hydrogen gas) + (oxygen gas) --> 2(liquid waters)

and

(methane) + oxygen gas --> (carbon dioxide) + 2(water(gas))

alright guys i need major help on these. I know I'm asking for alot and i need these answers by tonight 2:00 am eastern time if you guys dont see this in time just save yourselves the time and dont attempt the problems.

use logarithmic differentiation to find the derivative of the function.
y = √x e^x^2 (x^2 + 1)^10

At noon, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 25 km/h. How fast is the distance between the ships changing at 4:00 pm.


Find the intervals of increase or decrease
find the local maxiumum and minimum values
find the intervals of concavity and the inflection points.
b(x) = 3x^2/3 - x

a rectangular storage container with an open top is to have a volume of 10 m^3. the length of its base is twice the width. Material for the base costs $10 per square meter. Material for the sides cost $6 per square meter. Find the cost of the materials for the cheapest such container.

ok like i seriously need help on this..i know i suck at science but help would be alot appreciated


Research 2 major greenhouse gases. For each gas:

1. Give the chemical name of the gas.
2. Give the chemical formula of the gas.
3. Give the major sources of the gas, including at least one chemical reaction each to illustrate how the gas is produced.
4. Give one meaningful action that citizens like you can take to help reduce the levels of these gases in our atmosphere.

This isnt really a homework but regardless its school stuff so Ill just ask in here.... Its a c++ related question....

#include <iostream>
#include <string>
using namespace std;

int main()
{
string aName = "George";
string userName;

cout << "Enter your first name: ";
cin >> userName;
if (userName==aName)
cout << "Greetings, George\n";
else if (userName < aName)
cout << "You come before George\n";
else
cout << "You come after George\n";

int n = userName.compare (0, 2, aName, 0, 2);
cout << "The first two letters of your name ";
if (n==0)
cout << "match ";
else if (n < 0)
cout << "come before ";
else
cout << "come after ";
cout << aName.substr (0, 2) << endl;
return 0;
}

Example from book: The output

Enter your first name: Alfred
You come before George
The first two letters of your name come before Ge

I just need to know what exactly is being compared between Alfred and George?????


THANKS in ADVANCE

Just wait for someone to ask a question and hop in and answer I guess.

On a side note, I can probably help people out a bit with Biology/Bio-Chemistry. I plan to enroll with Bio-chemistry as my major after next year. No guarantees though.
