Answer:

amount of charge

Explanation:

Oxygen and sulfur are both in Group 16, which means they have a -2 charge. They have two more electrons than protons, making the charge of the ion negative.

Hope that helps.

An average reaction rate is calculated as the change in the concentration of reactants or products over a period of time in the

Sauron [17]

Answer:

a) 0.000112 M/s is the average reaction rate between 0.0 seconds and 1500.0 seconds.

b) 0.00011 M/s is the average reaction rate between 200.0 seconds and 1200.0 seconds.

c) Instantaneous rate of the reaction at t=800 s :

Instantaneous rate : $\frac{0.031 M}{800.0 s}=3.875\times 10^{-5} M/s$

Explanation:

Average rate of the reaction is given as;

$R_{avg}=-\frac{\Delta A}{\Delta t}=\frac{A_2-A_1}{t_2-t_1}$

a.) The average reaction rate between 0.0 s and 1500.0 s:

At 0.0 seconds the concentration was = $A_1=0.184 M$

$t_1=0.0s$

At 1500.0 seconds the concentration was = $A_2=0.016 M$

$t_2=1500 s$

$R_{avg]=-\frac{0.016 M-0.184 M}{1500.0 s-0.0 s}=0.000112 M/s$

0.000112 M/s is the average reaction rate between 0.0 seconds and 1500.0 seconds.

b.) The average reaction rate between 200.0 s and 1200.0 s:

At 0.0 seconds the concentration was = $A_1=0.129 M$

$t_1 =200.0 s$

At 1500.0 seconds the concentration was = $A_2=0.019M$

$t_2=1200 s$

$R_{avg]=-\frac{0.019 M-0.129M}{1200.0s-200.0s}=0.00011 M/s$

0.00011 M/s is the average reaction rate between 200.0 seconds and 1200.0 seconds.

c.) Instantaneous rate of the reaction at t=800 s :

At 800 seconds the concentration was = $A=0.031 M$

$t =800.0 s$

Instantaneous rate : $\frac{0.031 M}{800.0 s}=3.875\times 10^{-5} M/s$

Nicotine, a component of tobacco, is composed of c, h, and n. a 4.725 −mg sample of nicotine was combusted, producing 12.818 mg

ehidna [41]

C = 12.818 mg CO2 (1 mmol CO2/44 mg CO2) (1 mmol C/1 mmol CO2) = 0.29 mmol

H = 3.675 mg of H2O (1 mmol H2O/18 mg H2O) (2 mmol H/1 mmol H2O) = 0.41 mmol

N = (4.725 mg – 0.29 * 12 – 0.41 * 1) * (1 mmol/14 mg) = 0.06 mmol

Divide everything by the smallest number:

C = 0.29/0.06 = 4.8 ~ 5

N = 0.06/0.06 = 1

Empirical formula is:
