A student is studying the ways different elements are similar to one another. Diagrams of atoms from four different elements are shown below. Nucleus Nucleus Atom 1 Atom 2 Nucleus Nucleus Atom 3 Atom 4
Answer:
atom 1 and atom 2
Explanation:
why does the second row of the periodic table have 8 elements
short asnwer:
here are 8 elements in period 2 because all those elements have electrons in the second shell and no electrons in the third shell.
Explanation:
There are certain rules for arranging atoms in shells 1) Maximum number of electrons in a shell is given by the formula 2n^2. 2) The outermost ( valence) shell can accomodate only 8 electrons.

9. Do all enzymes function at the same pH?
Each enzyme has an optimum pH but it also has a working range of pH values at which it will still work well. This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. ... Catalase has an optimum pH of 9 and a working range of between pH 7-11. Hope this was helpful

1. Sequence Order the path of a sound wave
from when it is produced by a source until
it is interpreted by the brain
Answer:1. The sound waves arrive at the pinna (auricle), the only visible part of the ear.
2. Once the sound waves have passed the pinna, they move into the auditory canal (external
acoustic meatus) before hitting the tympanic membrane (eardrum).
3. Once the sound waves reach the tympanic membrane, it begins to vibrate and they enter
into the middle ear.
4. The vibrations are transmitted further into the ear via three bones (ossicles): malleus
(hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from
the tympanic membrane to the oval window.
5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.
6. Hair cells in the organ of Corti (within the cochlea) are stimulated which in turn
stimulates the cochlear branch of the vestibulocochlear nerve.
7. The cochlear nerve then transmits electrical impulses to the auditory region of the brain
in the temporal lobe.

Le Châtelier's principle:
When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.
• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.
☆ Why can heat be written on the same side of the products when the reaction is exothermic?
• Exothermic means that heat is released, thus heat can be treated as a product.
• I like to remember it as Exothermic → Exit

Sand is composed of silicon dioxide SiO2. A 210 gram sample has how many moles?
The number of moles of 210 gram sample of sand contains 3.5 moles of mole of SiO₂
Sand is composed of silicon dioxide (SiO₂).
Therefore, let's calculate the molecular mass of SiO₂ . Therefore,
Molecular mass of SiO₂The molecular mass of the compound is the sum of the atomic mass of the compound.
SiO₂ = 32 + (16 × 2) = 28 + 32 = 60 g/molTherefore,
60 g = 1 mole of SiO₂
210 g = ?
cross multiply
number of moles = 210 / 60
number of moles = 21 / 6
number of moles = 3.5 moles

in the reaction :N2 + 3H2----2NH3 how many grams of H2 are needed to produce 1 mole on ammonia
The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.
Calculation of the number of grams:Here we begins the moles of ammonia for production after this it convert the number of moles of h2 for getting one mole of ammonia and then finally convert into grams
So it be like
[tex]= 1\ mol NH_3 \frac{3H_2}{2NH_3}\frac{1.01g }{1\ mol H_2}[/tex]
= 1.52 g Hz
Hence, The number of grams that are needed to produce 1 mole on ammonia is to be considered as the 1.52 g Hz.
