When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound<span>. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
Hope this helps.</span>
When an ionic is placed in water a dissolving reaction occurs so the positive or negative ion are only attracted to each other
The number of hydrogen atoms that are in 4.40 mol of ammonium sulfide is 2.12 x10^25 atoms
calculation
find the number of moles of Hydrogen in ammonium sulfide (NH4)2S
that is 4.40 x number of hydrogen atoms in (NH4)2S ( 4x2= 8 atoms)
moles is therefore= 4.40 x8= 35.2 moles
by use of Avogadro's law constant
that is 1mole = 6.02 x10^23 atoms
35.2 moles=?
by cross multiplication
{35.2 moles x 6.02 x10^23} /1 mole = 2.12 x10^25 atoms
Answer:
When plastics decomposed, they produce methane gas, which contributes to global warming (not questioning beliefs on the matter). Plastic debris also is an issue affecting the ecology of an environment and can cause issues for the affected organisms. But the greenhouse gases released from biodegradable plastics is likely a greater concern.
Is there a picture of the isotope or?- becaue I can’t help if I don’t have a visual.
