Answer:
im pretty sure the electron configuration of the barium ion Ba+2 is [Kr]5s24d105p6
Explanation:
Answer:

Explanation:
Data provided as per the question below:-
Wavelength = 430.nm
The computation of the frequency of the light is shown below:-
Frequency = Velocity of light ÷ Wavelength
The Velocity of light = 
Wavelength = 430 nm =
m
Frequency = 


= 
Therefore for determining the frequency we simply applied the above formula.
Answer:
<h2>0.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
volume = final volume of water - initial volume of water
volume = 35 - 8 = 27 mL
We have

We have the final answer as
<h3>0.52 g/mL</h3>

Answer:
They form when plates collide. I hope this helps you!
Answer:
2.33g of iron (iii) chloride
50.0 mL of 5.00 M of sodium phosphate
FeCl3 + Na3PO4 > Fe(PO4) + 3NaCl
mol = conc × vol = 0.5 × 50/1000 = 0.025 mol Na3PO4
from the equation:
1 mol of Na3PO4 reacts with 1 mol FeCl3 = 3 mol of NaCl
0.025 mol = x
x = 0.0025 × 3 = 0.075 mol NaCl
mass = 0.075 g × 59 g/mol = 4.425 g NaCl
i guessed all of this so i dont know i it is correct
