Coefficients are used here to balance the number of elements in the products and reactants. Coefficients are numbers that are placed in front of a chemical formulas in an equation. Hope it's useful.
Answer:
Conduction is heat transfer through the direct contact of two subjects. The best example of this would be C, because it is the direct transfer of heat from the lightbulb to your hand. :)
Answer:
The answer to your question is below
Explanation:
Data
Substance = NaCl
moles of NaCl = 49
volume = 150 ml
Process
Molarity is a unit of concentration that makes a relation of the moles of a substance and the volume.
Molarity = moles / volume (L)
1.- Convert 150 ml to L
1000 ml ------------------ 1 L
150 ml ----------------- x
x = (150 x 1) / 1000
x = 0.15 L
2.- Substitution
Molarity = 49 / 0.15
Molarity = 326. 7
I have a doubt if the number of moles is 49 moles or 49μmoles
The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
