Answer:
Mass of N2 required = 1.429 g
Explanation:
The given reaction is:
N2(g) + 3H2(g) → 2NH3(g)
Mass of NH3 formed = 1.7 g
Molar mass of NH3 = 17 g/mol
Based on the reaction stoichiometry:
1 mole of N2 forms 2 moles of NH3
Therefore, moles of N2 required to produce 0.1 moles of NH3 is:
Molar mass of N2 = 28 g/mol
Mass of N2 required = moles*molar mass = 0.05*28 = 1.4 g
This is the theoretical mass corresponding to a 100% yield. Since the yield of NH3 is 98%, the corresponding mass of N2 required would be:
Answer:
They produce ions when dissolved in water.
Explanation:
Acids and bases have the characteristic in common to each other. Both of them have the property of reacting and dissolving in the water. Both acids and bases lead to the production of the ions when they are placed in a water solution. Acids produce Hydrogen ions when they are dissolved in water. Bases produce hydroxide ion when they are dissolved in water.

The number of moles of iron needed to react with 16.0 moles of sulfur is 128.0 moles.
Given equation, 8Fe + S8 = 8 FeS
Moles of sulfur = 16.0
To react 1 mole of sulfur, we need 8 moles of Fe
So, for 16.0 moles of sulfur we need
Thus, to react with 16.0 moles of Sulfur, 128.0 moles of Fe is needed.

Answer:
To react with 16.0 moles of sulfur we need 128.0 moles of iron (Fe).
Explanation:
Step 1: Data given
Number of moles Sulfur = 16.0 moles
Step 2: The balanced equation
8 Fe + S8 → 8 FeS
Step 3: Calculate mole Fe
For 8 moles Fe we need 1 mol S8 to produce 8 moles FeS
For 16.0 moles of Sulfur we need 8*16.0 = 128.0 moles
To react with 16.0 moles of sulfur we need 128.0 moles of iron (Fe).

Leptón
Answer:
Leptón
Explanation:
Lepton son partículas elementales de espín de medio entero (espín 1⁄2), y se sabe que no experimentan interacciones fuertes. Los leptones se clasifican en leptones cargados (los leptones similares a los electrones) y leptones neutros (conocidos como neutrinos). Un electrón es un leptón. Los leptones cargados pueden combinarse con otras partículas para formar átomos compuestos de partículas y positronio, mientras que los neutrinos rara vez interactúan con algo, lo que los hace raros de observar.
Dado que la electricidad es el resultado del movimiento o flujo de electrones, la única partícula representativa de esta fuerza es el leptón.
B) Respiration O2 photosynthesis CO2
C) Photosynthesis H2 Respiration O2
D) Respiration CO2 photosynthesis H2
the answer is A:
Photosynthesis release O2 (oxygen)
then animals use oxygen for respiration and release Co2
The correct answer is A) Photosynthesis O2 Respiration CO2. Photosynthesis converts CO2 to O2, which is then used in respiration to be converted back into CO2. Both processes together create a continuous cycle.
The correct diagram that represents the cycling of gases between photosynthesis and respiration is A) Photosynthesis O2 Respiration CO2. Through the process of photosynthesis, plants convert carbon dioxide (CO2) and sunlight into oxygen (O2) and glucose. Organisms, including the plants themselves, then use that oxygen for respiration, during which they convert the oxygen back into carbon dioxide. The glucose is used for energy. This continuous cycling plays a critical role in life on Earth.

There are various kind of elements that are present in periodic table. Elements that are metals are kept on left side of periodic table and elements which are non metals are kept on right side of periodic table.
Periodic table is a table in which we find elements with properties like metals, non metals and metalloids element arranges in increasing atomic number.
The first 20 elements of periodic table are Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfur, Chlorine, Argon, Potassium and Calcium. Out of these Lithium, Beryllium, Sodium, Magnesium. Potassium and Calcium are metals so they are kept on the left side of the periodic table while others are non metals so they are kept on right side of periodic table.
