Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
To calculate for the structure
of an element, you need to have a solid analyzer such as an x ray
diffractometer to determine the elements’ structure. It is hard to determine it
without any help of instrument because of its size.
Answer:
A. The energy stored in atmospheric carbon dioxide is conserved because it is used to create new forms of energy present in decomposed plants.
Explanation:
In the carbon cycle image, the result of an industry's work releases carbon dioxide into the atmosphere (this is represented by the letter G), this carbon dioxide is stored in the atmosphere (letter C) and then absorbed by plants during the process. of photosynthesis (letter A).
The carbon cycle is constituted by the absorption of carbon dioxide by plants in the photosynthesis process. Half of this absorbed carbon is released into the atmosphere and the other half the vegetable uses to produce sugars (glycoses). By ingesting the plants, the animals ingest together the carbon to their body, being released through respiration or decomposition. Because some fungi and bacteria are responsible for the decomposition of both animals and vegetables, they ingest part of this carbon, releasing it into the atmosphere and soil. In addition to bacteria, the burning process also releases carbon dioxide into the soil and atmosphere. Vegetables, through the breathing process, also absorb carbon dioxide and release oxygen unlike animals.
Answer:
Explanation:
We are given the mass of two reactants, so this is a limiting reactant problem.
We know that we will need mases, moles, and molar masses, so, let's assemble all the data in one place, with molar masses above the formulas and masses below them.
M_r: 17.03 32.00 18.02
4NH₃ + 5O₂ ⟶ 4NO + 6H₂O
m/g: 70.1 70.1
Step 1. Calculate the moles of each reactant
Step 2. Identify the limiting reactant
Calculate the moles of H₂O we can obtain from each reactant.
From NH₃:
The molar ratio of H₂O:NH₃ is 6:4.
From O₂:
The molar ratio of H₂O:O₂ is 6:5.
O₂ is the limiting reactant because it gives the smaller amount of H₂O.
Step 3. Calculate the theoretical yield.
