Answer:

mol H2S = 1.28 mol

Explanation:

balanced reaction:

2HCl + Na2S → H2S + 2NaCl

∴ moles HCl = 2.56 mol

⇒ moles H2S = ?

⇒ moles H2S = (2.56 mol HCl)*(mol H2S/2 moles HCl)

⇒ moles H2S = 1.28 mol

Which of the following characteristics do Element I and Element I have in common?

Nesterboy [21]

Answer:

Option C. The same number of energy levels.

Explanation:

From the diagram given above, element (i) belong to group 2 while element (ii) belong to group 6.

Also, both element i and ii belong to the same period (i.e period 4). This simply means that both element i and ii have the same number of energy levels.

NOTE: Elements in the same period have the same number of shells of electrons which simply means they have the same energy levels.

Linda has two glasses of apple juice. Glass A has 40 grams of juice at 25 °C. Glass B has 40 grams of juice at 40 °C. Which of t

IgorLugansk [536]

<h2>Answer:</h2>

In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.

As kinetic energy is directly proportional to temperature.

To make the kinetic energy of the molecules equal she should:

Heat one glass of 25°C to 40°C.

or

Cool the juice of 40°C to 25°C

Calcium bicarbonate (Ca(HCO3)2) Ca:H:C:O = 1:2:2 ___ Lithium sulfide (Li:2s) Li:S = 2:__

Anastaziya [24]

Answer: The ratio of atoms in calcium bicarbonate ; Ca : H : C : O = 1:2:2:6.

The ratio of atoms in lithium sulfide; Li : S = 2 : 1

Explanation:

In calcium bicarbonate: $Ca(HCO_3)_2$

In a molecular formula of calcium carbonate there are:

Number of Calcium atoms = 1

Number of Hydrogen atom = 1 × 2 = 2

Number of Carbon atoms = 1 × 2 = 2

Number of Oxygen atoms = 3 × 2 = 6

So, Ca : H : C : O = 1 : 2 : 2 : 6

In lithium sulfide : $Li_2S$

In a molecular formula of lithium sulfide there are:

Number of Lithium atoms = 1 × 2 = 2

Number of Sulfur atoms = 1

So, the Li : S = 2 : 1
