The answer to this question would be: 2; 3; 3

In nitrogen gas structure, there are 5 total electron pairs which were made by 2.5 electron pairs(5 electrons) for every nitrogen atom. In the middle, you will found 3 pair making bond order 3. In each nitrogen, there will be 1 nonbonding electron making it a total 2 unbonding electron pairs.

Atoms of what class of elements are used to absorb electrons in electron-dense stains?
lesantik [10]

The elements of heavy metals are used to absorb electrons in electron-dense stains.

<h3>What are heavy metals?</h3>

A heavy metals are generally defined as metals with relatively high densities, atomic weight and atomic number.

They toxic and poisonous in nature. They occurs naturally and are very essential to life.

Arsenic, cadmium, lead, copper, nickel and mercury are the most commonly used heavy metals.

Electron staining means to absorb heavy metals of high scattering power to biological specimens which exhibit a small scattering power for electrons.

Thus, the elements of heavy metals are used to absorb electrons in electron-dense stains.

A 250 cm^3 solution containing 1,46 g of sodium chloride is added to an excess of silver nitrate solution. The reaction is given
faust18 [17]

Answer:

The mass of the precipitate  that AgCl is 3.5803 g.

Explanation:

a) To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}

We are given:

Mass of solute (NaCl) = 1.46 g

Molar mass of sulfuric acid = 58.5 g/mol

Volume of solution = 250 cm^3 =250 mL

1 cm^3= 1 ml

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{1.46g\times 1000}{58.5g/mol\times 250}\\\\\text{Molarity of solution}=0.09982 M

0.09982 M is the concentration of the sodium chloride solution.

b) NaCl (aq)+AgNO_3 (aq)\rightarrow AgCI(s)+NaNO_3(aq)

Moles of NaCl = \frac{1.46 g}{58.5 g/mol}=0.02495 mol

according to reaction 1 mol of NaCl gives 1 mol of AgCl.

Then 0.02495 moles of NaCl will give:

\frac{1}{1}\times 0.02495 mol=0.02495 mol of AgCl

Mass of 0.02495 moles of AgCl:

0.02495 mol\times 143.5 g/mol=3.5803 g

The mass of the precipitate  that AgCl is 3.5803 g.

Hey please answer this for me thanks.
Aleks [24]

Explanation:

Moles of N2 = 84/28 = 3.0mol

Moles of H2 = 29/2 = 14.5mol

Hence amount of ammonia produced = 6.0 * 17 = 102g.

A 25.0 g sample of an alloy was heated to 100.0 oC and dropped into a beaker containing 90 grams of water at 25.32 oC. The tempe
elena55 [62]

Answer:

The specific heat of the alloy C_{a} = 0.37 \frac{KJ}{Kg K}

Explanation:

Mass of an alloy m_{a} = 25 gm

Initial temperature T_{a} = 100°c = 373 K

Mass of water m_{w} = 90 gm

Initial temperature of water T_{w} = 25.32 °c = 298.32 K

Final temperature T_{f} = 27.18 °c = 300.18 K

From energy balance equation

Heat lost by alloy = Heat gain by water

m_{a} C_{a}  [T_{a} - T_{f}] = m_{w} C_w (T_{f} -T_{w} )

25 × C_{a} × ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)

C_{a} = 0.37 \frac{KJ}{Kg K}

This is the specific heat of the alloy.
