Add more drink mix until you notice a color change. Have you increased or decreased the concentration? (Higher number means a higher concentration).

Answers

Answer:

Increased the concentration

Explanation:

Complete Question

Open the simulation by pushing the play button.  Begin by dragging the concentration tester overto the liquid and add drink mix until the concentration reaches approximately 2.oo mol/L.  This means there are 2.00 moles of the drink mix in 1 Liter of the solution. Add more drink mix until you notice a color change. Have you increased or decreased the concentration? (Higher number means a higher concentration).

Solution

Drink mix is basically the solute which is added to solvent i.e water.

The higher is the amount of drink mix in the solvent, the higher is the concentration of the solute and hence darker is the color of the drink.

Hence, in the case the concentration of the drink has been increased.

What two metals are have atoms larger than that of sodium

Answers

Answer: potassium and rubidium

Explanation:

1) The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). These metals are called alkali metals because they form alkalies( i.e. strong bases capable of neutralizing acids) when they react with water.

2) The heavier alkali metals (K, Rb, and Cs) react so vigorously that they invariably explode.

3) This trend, which is not consistent with the relative magnitudes of the reduction potentials of the elements, serves as another example of the complex interplay of different forces and phenomena—in this case, kinetics and thermodynamics.

If your end product is 1.5 moles of KMnO4, how many moles of manganese oxide were used in the reaction?

The equation for the production of potassium permanganate is as follows:

2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2
You must show all work

Answers

Answer:

1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2

Explanation:

The balanced equation of this chemical reaction is

2 MnO2 + 4 KOH + O2 → 2 KMnO4 + 2 KOH + H2

2 moles of MnO2 produces 2 moles of   KMnO4

That means 1 moles of KMnO4 will be produced from 1 moles of MnO2

Hence, 1.5 moles of KMnO4 will be produced from 1.5 moles of MnO2

The moles of manganese oxide were used in the reaction is 1.5 moles.

What is stoichiometry?

Stoichiometry of any reaction tells about the relative amount of species present before and after the chemical reaction.

Given chemical reaction is:

2MnO₂ + 4KOH + O₂ → 2KMnO₄ + 2KOH + H₂

From the stoichiometry of the reaction, it is clear that same moles of manganese oxide and potassium permanganate is involved in the reaction.

2 moles of KMnO₄ = produce by 2 moles of MnO₂

1.5 moles of KMnO₄ = produce by 2/2×1.5=1.5 moles of MnO₂

Hence, required moles are 1.5 moles.

Global climate change is a result of human activity?

Answers

Answer:

Yes

Explanation:

Due to pollution, greenhouse gasses, etc

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
