Answer:

Argon is an element on the periodic table. It is a member of the noble gasses, meaning that it is a monoatomic pure gas. In other words, argon gas particles are simply pure single atoms of argon. ... Finally, water is a polyatomic molecule H2O composed of two atoms of hydrogen and one atom of oxygen.

A first-order decomposition reaction has a rate constant of 0.00440 yr−1. How long does it take for [reactant] to reach 12.5% of
mina [271]

Answer:

473 year

Explanation:

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

Given:

To reach 12.5% of reactant means that 0.125 of [A_0] is decomposed. So,

\frac {[A_t]}{[A_0]} = 0.125

t = ?

\frac {[A_t]}{[A_0]}=e^{-k\times t}

0.125=e^{-0.00440\times t}

t = 473 year

A container with two gases, helium and argon, is 30.0% helium. Calculate the partial pressure of helium and
iVinArrow [24]

Answer:

helium=1,2atm

argon=2,8atm

Explanation:

partial is pressure exerted by each gas in a system since 30% is helium it means 70% is argon

argon =70%x4

helium=30%4

Balance the following redox equation using the smallest integers possible and select the correct coefficient for the hydrogen su
goldfiish [28.3K]

Answer:

Coefficient of HSO_{3}^{-} is 5

Explanation:

Oxidation: MnO_{4}^{-}(aq)\rightarrow Mn^{2+}(aq)

  • Balance O and H in acidic medium: MnO_{4}^{-}(aq)+8H^{+}(aq)\rightarrow Mn^{2+}(aq)+4H_{2}O(l)
  • Balance charge : MnO_{4}^{-}(aq)+8H^{+}(aq)+5e^{-}\rightarrow Mn^{2+}(aq)+4H_{2}O(l) .............(1)

Reduction: HSO_{3}^{-}\rightarrow SO_{4}^{2-}

  • Balance O and H in acidic medium : HSO_{3}^{-}(aq)+H_{2}O(l)\rightarrow SO_{4}^{2-}(aq)+3H^{+}(aq)
  • Balance charge : HSO_{3}^{-}(aq)+H_{2}O(l)-2e^{-}\rightarrow SO_{4}^{2-}(aq)+3H^{+}(aq) ..............(2)

[2\times eq(1)]+[5\times eq(2)] -

Balanced equation: 2MnO_{4}^{-}(aq)+5HSO_{3}^{-}(aq)+H^{+}(aq)\rightarrow 2Mn^{2+}(aq)+5SO_{4}^{2-}(aq)+3H_{2}O(l)

Coefficient of HSO_{3}^{-} is 5
