What is the balanced equation of iron (iii) hydrogen carbonate?​
Lynna [10]
<h3>Answer:</h3>

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

<h3>Explanation:</h3>
  • A decomposition reaction is one in which a large compound is broken down into smaller compounds or individual elements.
  • The decomposition reaction Iron (iii) hydrogen carbonate yield iron (iii) carbonate, water and carbon dioxide.

        Fe(HCO₃)₃ → Fe₂(CO₃)₃ + H₂O + CO₂

  • A balanced equation is the one in which the number of atoms of each element are equal on both side of the equation.
  • Therefore; the balanced equation for the decomposition of Iron (iii) hydrogen carbonate is given by;

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

In the lewis structure of ch3oh, how many bonding pairs of electrons are there?
zysi [14]
Answer:
            There are five <span>bonding pairs of electrons in Methanol.

Explanation:
                   Those electron pairs which are being shared between two atoms in molecule are called as bonding pair electrons. While, those electron pairs which are not involved in bond formation and are not shared between two atoms are called as Non-Bonding electron pairs.
                   In molecule of Methanol as shown below, it can be seen that carbon atom is forming four bonds with three hydrogen atoms and one oxygen atom by sharing four electron pairs and oxygen is forming two bonds, one with carbon atom and one with hydrogen atom. There are two lone pair of electrons present on oxygen atom which are not taking part in and formation.</span>

Lridium-192 is an isotope of iridium and has a half-life of 73.83 days. if a laboratory experiment begins with 100 grams of irid
fiasKO [112]
Radioactive material undergoes first order dissociation kinetics.

For 1st order system,
k = 0.693 / t1/2
where, t 1/2 = half-life of the radioactive disintegration process.

Given that, t 1/2  = <span>73.83 days
Therefore, k = 0.009386 day-1

Also, for 1st order reaction,
k = </span>\frac{2.303}{t} log \frac{Co}{Ct}

Given that, Co = initial concentration of <span>Iridium-192 = 100 g

Therefore, </span>0.009386 = \frac{2.303}{t} log \frac{100}{Ct}

On rearranging we get, Ct = 100 (0.990656)^{t}

Answer: Ct = 100 (0.990656)^{t} equation approximates the amount of Iridium-192 present after t days
