Negatively charged ions move to the positive electrode during electrolysis. They lose electrons and are oxidised . The substance that is broken down is called the electrolyte.

Answer:

La electrólisis es un proceso físico por el que se descompone una sustancia en disolución a través de la corriente eléctrica. Para que la electrólisis sea posible es necesaria una fuente de alimentación continua, una disolución iónica y dos polos (ánodo y cátodo), que atraen hacia sí los iones de signo opuesto.

The theoretical yield of a reaction is the amount of product obtained if the limiting reactant is completely converted to produc

docker41 [41]

Answer:

The theoretical yield of NH3 produced by the reaction is 16.89 grams

Explanation:

Step 1: Data given

Mass of N2 = 13.90 grams

Molar mass of N2 = 28.0 g/mol

Mass H2 = 6.440 grams

Molar mass H2 = 2.02 g/mol

Step 2: The balanced equation

N2(g) + 3 H2(g) → 2 NH3(g)

Step 3: Calculate moles

Moles = mass / molar mass

Moles N2 = 13.90 grams / 28.0 g/mol

Moles N2 = 0.496 moles

Moles = 6.440 grams / 2.02 g/mol

Moles H2 = 3.19 moles

Step 4: Calculate limiting reactant

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

N2 is the limiting reactant. It will completely be consumed (0.496 moles)

H2 is in excess. There will react 3*0.496 = 1.488 moles

there will remain 3.19 - 1.488 = 1.702 moles

Step 5: Calculate moles NH3

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

For 0.496 moles N2 we will have 2*0.496 = 0.992 moles NH3

Step 6: Calculate mass NH3

Mass NH3 = moles NH3 * molar mass NH3

Mass NH3 = 0.992 moles * 17.03 g/mol

Mass NH3 = 16.89 grams

The theoretical yield of NH3 produced by the reaction is 16.89 grams

1. What are the rows of the periodic table called and what do they tell us?

Vedmedyk [2.9K]

Answer:

The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.

Each row represents one period; the period number of an element indicates how many of its energy levels house electrons. Sodium, for instance, sits in the third period, which means a sodium atom typically has electrons in the first three energy levels.

Carbon monoxide reacts with oxygen to form carbon dioxide by the following reaction: 2 CO(g) + O2(g) → 2 CO2(g) ∆H for this reac

klio [65]

Answer:

Heat released =811.68kcal

Explanation:

2 CO(g) + O2(g) → 2 CO2(g) ΔH=-135.28kcal

for this type of question 1st balance the chemical reaction and use unitry method.

From the above balanced equaion it is clearly that,

2 mole of CO reacts with 1 mole of O2 and we have sufficient amount of oxygen means excess amount.

and also for complete consumption of 2 mole of CO, ΔH=-135.28 kcal

for complete consumption of 12 moles of CO2 ΔH= $6\times (-135.28kcal)$

Heat released =811.68kcal

alex41 [277]

Answer:

B. The question can be tested in one experiment.

Explanation:

A well defined question is one complete in scope and can support comprehensive investigation through experiment or scientific methods. Here empirical analyses can be carried out to unravel answers to such question. Usually well defined questions could take the form of problem statement or research question.
