Answer:

28.7 grams of water

Explanation:

Calorimetry problem:

Q = C . m . ΔT

2400 J = 4.18 J/g°C . m . (30°C - 10°C)

2400 J = 4.18 J/g°C . m . 20°C

2400J = 83.6 J/g . m

2400J / 83.6 g/J = m

28.7 g = m

How many molecules of co2 would there be in 30 moles of co2

rjkz [21]

Answer:

= 1.806 × 10^25 molecules.

Explanation:

1 mole of CO2 contains 6.02 × 10^23 molecules

30 moles of CO2 will contain ( 30 × 6.02 × 10^23 )

= 1.806 × 10^25 molecules.

Which solution has the lowest freezing point?

elena55 [62]

The solution of Ba(OH)2 will have the lowest freezing point. This is because it dissociates into 3 ions, one Ba and 2 OH, which is more than any of the others. Freezing point depression is a colligitive property of water that depends, in part, on the number of ions.

Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydro

Dahasolnce [82]

The product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

<h3>What is the reaction between sulfuric acid and potassium hydroxide?</h3>

The result will be, H+ from H₂SO₄ reacts with OH- from KOH to generate H₂O. Also, K+ reacts with SO₄²⁻ to create K₂SO4₄

As a result, the balanced equation will be:

$\rm H_2SO_4 + 2KOH --- > K_2SO_4 + 2H_2O$

Thus, the product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. Sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.
