Answer:

7.03 g

Explanation:

Step 1: Write the balanced synthesis reaction

N₂(g) + 3 H₂(g) ⇒ 2 NH₃(g)

Step 2: Calculate the moles corresponding to 32.5 g of N₂

The molar mass of N₂ is 28.01 g/mol.

32.5 g × 1 mol/28.01 g = 1.16 mol

Step 3: Calculate the number of moles of H₂ needed to react with 1.16 moles of N₂

The molar ratio of N₂ to H₂ is 1:3. The moles of H₂ needed are 3/1 × 1.16 mol = 3.48 mol.

Step 4: Calculate the mass corresponding to 3.48 moles of H₂

The molar mass of H₂ is 2.02 g/mol.

3.48 mol × 2.02 g/mol = 7.03 g

Answer:

a. NO is added to the reaction mixture ⇒ to the left

b. BrNO is added to the reaction mixture ⇒ to the right

c. Br₂ is removed from the reaction mixture ⇒ to the right

d. Pressure is increased ⇒ to the left

Explanation:

The reaction at equilibrium is the following:

2BrNO (g) → 2NO (g)+ Br₂ (g)

The left side is the reactants side (2 BrNO) and the right side is the products side (2 NO + Br₂).

a. NO is added to the reaction mixture

NO is a product, in the right side of the equation. If a product is added, the equilibrium will shift to the opposite side, to the left, to form more reactants and compensate for the addition.

b. BrNO is added to the reaction mixture

BrNO is a reactant, in the left side of the equation. If a reactant is added to a reaction at equilibrium, more product will be formed in compensation. Therefore, the equilibrium will shift to the right.

c. Br₂ is removed from the reaction mixture

Br₂ is a product, in the right side. If it is removed, the system will compensate for the remotion by forming more product, so the reaction will shift to the right.

d. Pressure is increased

Since both reactants and products are in the gas phase, the equilibrium is affected by pressure. If pressure is increased, the equilibrium will shift to the side of the reaction with the fewest number of moles. The reactants side (left) has 2 moles of BrNO while the products side (right) has 3 moles (1 mol NO + 1 mol Br₂ = 3 moles of gas). Therefore, the reactants side has the fewest number of moles, so the equilibrium will shift to the left.

Carbon has an outer shell consisting of 4 valence electrons. ... Thus, a carbon ion can have a charge of anywhere from -4 to +4, depending on if it loses or gains electrons. Although the most common oxidation states of carbon are +4 and +2, carbon is able to make ions with oxidation states of +3, +1, -1, -2, and -3.

While recording the crime scene, the photographer snapped a picture of his partner posing beside the famous victim's body. After printing the photo for his partner, he should just delete the image so nobody gets in trouble is false.

Photographer is defined as a specialist who concentrates on the craft of shooting pictures with a digital or film camera. We can now describe the present, visualize the future, and visualize the history thanks to photography. The predecessor to the contemporary digital camera was the camera obscura. In the past, paintings were the most popular medium for capturing important historical events.

An approach known as "painting with light" is frequently used by seasoned photographers to expose image details in dim or near-dark lighting. By holding the shutter open for a few seconds or minutes while moving around the scene, the photographer can add light from sources like a flashlight or a flash from a separate camera.

The photographer's partner was photographed posing next to the body of the well-known victim as he documented the murder scene. It is erroneous to say that after printing the photo for his spouse, he should immediately erase it.

Answer:

Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character.

Explanation:

These six are the major trends.

Answer:

The ration of molar concentration is "2.5".

Explanation:

The given values are:

Average density of salt water,

= [tex]1.03 \ g/cm^3[/tex]

Net pressure,

= [tex]2.00 \ atm[/tex]

Increase in pressure,

= [tex]1.00 \ atm[/tex]

Now,

The under water pressure will be:

=  [tex]\frac{15 \ m}{10}\times 1 \ atm +1 \ atm[/tex]

=  [tex]1.5\times 1+1[/tex]

=  [tex]1.5+1[/tex]

=  [tex]2.5 \ atm[/tex]

hence,

The ratio will be:

=  [tex]\frac{(\frac{n}{V})_{15m} }{(\frac{n}{V})_{surface} }[/tex]

or,

=  [tex]\frac{P}{P_s}[/tex]

=  [tex]\frac{2.5}{1}[/tex]

=  [tex]2.5[/tex]

Ph = 6.12....

here ya go

Explanation:

-

The pH of the solution with a concentration of 7.6 × [tex]10^{-7}M[/tex] [tex]H_{3}O^{+}[/tex]will be 6.12.

The pH of water indicates how acidic or basic it is. The scale runs from 0 to 14, with 7 representing neutrality. Acidity is indicated by a pH less than 7, while a pH greater than 7 denotes a base. The relative number of free hydrogen, as well as hydroxyl ions in water, and hydroxyl ions in water is measured by pH .

It is known that ,[[tex]H_{3}O^{+}[/tex]]=[tex][H^{+} ][/tex]

pH can be calculated by the formula:

[tex]pH = -logH^{+}.[/tex]

Now, put the value of hydrogen ion in above equation

pH = -log[7.6×10^{-7}M]

      = -log(7.6)-log(10^{-7}

       = -0.88+7log 10

       = -0.88 +7

        = 6.12.

Therefore, the pH of the solution will be 6.12.

Answer:

The empirical formula of a compound is the simplest whole number ratio of atoms of each element in the compound. It is determined using data from experiments and therefore empirical.

For example, the molecular formula of glucose is C 6H 12O 6 but the empirical formula is CH 2O.

Answer:

a chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms in the molecule CH2O is the empirical formula for glucose.

Answer:

See Explanation

Explanation:

The reaction equation is

3H2(g) + N2(g) -----> 2NH3(g)

1)If 1 mole of N2 yields 2 moles of NH3

12 moles of N2 will yield 12 * 2/1 = 24 moles of NH3

2) 3 moles of nitrogen reacts with 1 mole of nitrogen

6 moles of hydrogen will react with 6 * 1/3 = 2 moles of nitrogen

3) The limiting reactant yields the least amount of product

If 1 mole of nitrogen yields 2 moles of NH3

40 moles of nitrogen yields 40 * 2/1 = 80 moles of NH3

If 3 moles of hydrogen yields 2 moles of NH3

30 moles of hydrogen yields 30 * 2/3 = 20 moles of NH3

Hence hydrogen is the limiting reactant

4) Number of moles in 80g of NH3 = 80g/17g/mol = 4.71 moles

3 moles of hydrogen produces 2 moles of ammonia

x moles of hydrogen produces 4.71 moles of ammonia

x = 3 * 4.71/2 = 7.065 moles of hydrogen

Mass = 7.065 moles of hydrogen * 2 g/mol

Mass = 14.13 g of hydrogen

Answer:

::Due to the iron inside the earth.

Explanation:

Imagine a sphere of Iron, as big as two-third the size of the moon and as hot as 5700 Kelvin. That is the Earth’s core.

The iron core isn't in its liquid form even at that temperature because it is crushed under immense gravity. This core is surrounded by 2000 km of other metals like iron and nickel which are in their molten state.

The temperature is not the same at every point in this molten layer. The hotter and less dense matter rises up, and the warm denser matter sinks. This causes convectional currents in the interior of the Earth.

Because of the Earth’s spin, there is a force that established called the Coriolis force which causes swirling whirlpools here too.

This flow of molten metals produces electric currents which generate self-sustaining magnetic fields. And as a result of the Coriolis force, all these combined effects add up to produce one big magnetic field engulfing the Earth aligned in one direction.
