Write the empirical formula for at least four ionic compounds that could be formed from the following ions:MnO4- , BrO3- , Fe2+ , Pb4+

Answers

HMnO₄ ; KMnO₄ ;  NaMnO₄; LiMnO₄
HBrO₃ ; KBrO₃ ; NaBrO₃ ; LiBrO₃
FeO ; FeCl₂ ; FeS ; FeSO₄
PbO₂ ; PbS₂ ; Pb(SO₄)₂ ; Pb(CO₃)₂

Final answer:

The empirical formulas for four ionic compounds given the ions MnO4-, BrO3-, Fe2+, and Pb4+ are Fe(MnO4)2 for Iron(II) permanganate, Pb(BrO3)4 for Lead(IV) bromate, Fe(BrO3)2 for Iron(II) bromate, and Pb(MnO4)4 for Lead(IV) permanganate.

Explanation:

The task is to write the empirical formula for ionic compounds that could be formed from specific ions. For the ions provided (MnO4−, BrO3−, Fe2+, Pb4+), we would pair each anion with a cation to neutralize the charge and create a stable ionic compound. Here are the empirical formulas for four possible ionic compounds:

  • Fe(MnO4)2: Iron(II) permanganate
  • Pb(BrO3)4: Lead(IV) bromate
  • Fe(BrO3)2: Iron(II) bromate
  • Pb(MnO4)4: Lead(IV) permanganate

Each formula is created by balancing the charges of the cations and anions to ensure that the overall charge of the compound is zero.

Explain the iodine clock reaction.

Answers

Iodine clock reaction is a combination of hydrogen peroxide and sulfuric acid. When these are poured together, there is no reaction at first, but after time, a colored reaction will happen to the liquid and may change back to the original color. This idea was discovered by Hans Landolt in the late 1800s.

Which reaction will most likely take place?Pt + FeCl3
Mn + CaO
Li + ZnCO3
Cu + 2KNO3

Answers

The correct answer of the given question above would be the third option: Li + ZnCO3. The reaction that will most likely take place is Li + ZnCO3. This is the reaction that will most likely take place since Lithium is very active. Hope this is the answer you are looking for. 

I agree, the answer is Li+ZnCO3.

Which two factors must be equal when a chemical reaction reaches equilibrium?(1) the concentration of the reactants and the concentration of the products
(2) the number of reactant particles and the number of product particles
(3) the rate of the forward reaction and the rate of the reverse reaction
(4) the mass of the reactants and the mass of the products

Answers

The correct answer is option 3. Equilibrium is achieved in a chemical reaction when the rate of the forward reaction is the same for the rate of the backward reaction and when the reaction has stopped.

Which of these features was formed by hotspot volcanism?The Grand Canyon
The Big Island of Hawaii
The Appalachian Mountains
The Himalaya Mountain Range

Answers

These feature that was formed by hotspot volcanism is The Big Island of Hawaii. The Hawaiian Islands are actually found at the tip of several volcanoes that has been formed by a series of volcanic eruptions. Today, the Big Island sits on the hotspot, and contains the only active volcanoes of the group of islands.
The Big Island of Hawaii was formed by hotspot volcanism, whereas The Grand Canyon, The Appalachian Mountains, and The Himalaya Mountain Range were not.

__________ is one of many factors that can determine the rate of alcohol absorption.

Answers

Food consumption affects the rate of alcohol absorption in the bloodstream.

Explanation:

The type of food and therefore the amount of food that is a gift in your epithelial duct once you consume alcohol have the foremost direct impact on the speed of alcohol absorption.

When you consume alcohol on the associate empty abdomen, the alcohol is sometimes absorbed within the blood among fifteen minutes to two-and-a-half hours. If you have got a moderate quantity of food in your abdomen once you drink, that speed slows all the way down to thirty minutes to a few hours. If you’re drinking on a full abdomen, alcohol absorption ranges from 3 to 6 hours.

Answer: The answer is C. Food.
