A drug user who has developed a high tolerance to a drug could take an overdose large enough to cause death.

Chemistry

If you're wanting to know true or false, then yes they can.

When they develop a tolerance for it, they don't get the same effects as the did before the tolerance, so then they'd take more of it to get those effects back. If they keep having to increase the amount, they eventually take too much, overdose, and in a lot of cases, die.

sertanlavr [38]

Answer:

Explanation:

HA(aq)+H2O(l)⟺H3O+(aq)+A−(aq)(1)

you need to solve for the Ka value. To do that you use

Ka=[H3O+][A−][HA](2)

Another necessary value is the pKa value, and that is obtained through pKa=−logKa

The procedure is very similar for weak bases. The general equation of a weak base is

BOH⟺B++OH−(3)

Solving for the Kbvalue is the same as the Ka value. You use the formula  

Kb=[B+][OH−][BOH](4)

The pKb value is found through pKb=−logKb  

The Kw value is found withKw=[H3O+][OH−].  

Kw=1.0×10−14(5)

A 12-liter tank contains helium gas pressurized to 160 \rm atm.How many 3-liter balloons could the 12-L helium tank fill? Keep i
Vikentia [17]

Answer:

636 balloons

Explanation:

If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:

  1. We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons:P_{1}=160 atm\\V_{1}=12 L\\P_{2}=1 atm\\V_{2}= ?
  2. To find out what would be this volume 2, we use the Boyle's Law: P_{1}V_{1}=P_{2}V_{2}\\V_{2}=\frac{P_{1}V_{1}}{P_{2}} \\V_{2}=\frac{160 atm \times 12L}{1 atm}\\V_{2}=1920 L
  3. Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1: V_{b}=V_{2}-V_{1}=1920L-12L=1908 L
  4. Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon:B=\frac{1908L}{3L} =636 balloons

How many moles of oxygen are in 1 mole of fe(no3)3?
Naddika [18.5K]
One mole of Fe(NO3)3, or iron(III) nitrate, has three moles of nitrate molecules, which have three moles of oxygen atoms each. We can show this mathematically:
1 mole Fe(NO3)3 * (3 moles NO3)/(1 mole Fe(NO3)3) = 3 moles NO3
3 moles NO3 * (3 moles Oxygen)/(1 mole NO3) = 9 moles Oxygen
9 moles of Oxygen in one mole Fe(NO3)3
