Explanation:
What you need to know here is that frequency and wavelength have an inverse relationship as described by the equation
mark me as Brainliest
Answer:The elements have the same number of electrons in the outer ring so they react with the same substances
The answer is d. particles move from an area of high concentration to low concentration.
The answer is D. Use the equation PV=nRT
P=(.567mol)(.0821)(300K)/4.5L
Answer:
im not sure but I hope this helps
Explanation:
I believe the equivalents is just the moles reactant/moles limiting reactant
water has a denisty of 1 g/mL. 1 L is 1000 ml so there are 1000g/L.
the molar mass of water is 18g/mol if you use the Liters in the equation above you can find the number of grams present. divide this number you found by 18 to find the moles.
now take the amount of the other reactant given and divide it by its own molar mass. this will give you the number of moles of that reactant.
divide the moles of water by the moles of the reactant and that is the equivalent.
to find the normality you take this number and divide it by the number of liters.
