Answer:

0.221M

Explanation:

From the question ,

The Molarity of AgNO₂ = 0.310 M

Hence , the concentration of Ag⁺ = 0.301 M

The volume of AgNO₂ = 250 mL

and,

The Molarity of Sodium chromate = 0.160 M

The volume of Sodium chromate = 100 mL.

As the solution is mixed the final volume becomes ,

250mL +100mL = 350mL

Now, using the formula , to find the final molarity of the mixture ,

M₁V₁ ( initial ) = M₂V₂ ( final )

substituting the values , in the above equation ,

0.310M * 250ml = M₂ * 350ml

M₂ = 0.221M

Hence , the concentration of the silver in the final solution = 0.221M

You are given a clear solution of KNO3. Using 3-4 sentences explain how you would determine if the solution is unsaturated,satur

Natasha2012 [34]

Without being given a temperature or amount of solute, it's not as easy to find the level of saturation. If there is excess of solvent in the beaker, the solution is unsaturated. In this case, the solution is clear so there is no indication of excess of solute or solvent. Therefore, the solution is saturated.

Answer:

0.72 mole of oxygen would produce 320.4 kJ of heat.

Explanation:

CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (ℓ) + 890kJ

According to the equation,

2 moles of O₂ produces 890 kJ of heat

So, 0.72 moles of O₂ will produce:

Therefore, 0.72 moles of oxygen would produce 320.4 kJ of heat.

How can litmus paper and phenolphthalein be used to tell whether a solution is an acid or a base? Be specific.

MArishka [77]

Both litmus paper and phenolphthalein are used as acid/base (pH) indicators.

Litmus paper:
Litmus paper will turn either blue or red when a drop of solution is added to the paper. Red indicates an acidic solution (pH is <4.5), and blue indicates a basic solution (pH >8.3).

Phenolphthalein:
Phenolphthalein is commonly used during acid/base titrations. When the solution is acidic and the indicator is added, it will remain colorless. If the solution is basic, the phenolphthalein will turn pink.
