Answer:
A replacement reaction occurs when elements switch places in compounds. This type of reaction involves ions. Generally, more reactive elements replace less reactive elements. A single replacement reaction occurs when one element replaces another element in one compound.
Explanation:
Just figured it out!
Answer:Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
The answer is D because it uses the electrical energy from the wall to create heat (Thermal) energy for the clothes
I think the correct answer from the choices listed above is option A. The additional piece of information needed to determine the molecular formula would be percent composition of carbon. A molecular formula is <span>a formula that gives the number of atoms of each of the elements present in one molecule of a specific compound.</span>
13.29 X 
moles of NaCl are in a pinch of salt and a pinch of salt has
approximately 3.29x formula units of NaCl.
<h3>What are moles?</h3>
The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12; its symbol is “mol”.
We know that 1 formula unit of sodium chloride has a molar mass of 58.44g/mol
Hence;
Mass of 1 formula unit = 58.44g
Mass of 3.29 x formula units
13.29 x x 58.44g
776.6676 x
Moles =
Moles = 13.29 X
Therefore;
13.29 X moles of NaCl are in a pinch of salt.
