Answer:
Antarctica and Australia were one landmass millions of years ago
Explanation:
Thats the answer I'm very sure of it
I think it's 45 miles. Don't know for sure though
Answer:
energy = 391.902 kJ /mol
Explanation:
given data
wavelength = 305 nm = 305 ×
m
to find out
average energy
solution
we know speed of light is 3 ×
m/s
so we find frequency here first by speed of light formyla
speed = wavelength × frequency
3 × = 305 × × frequency
frequency = 9.8360 ×
so energy is
energy = hf
here h = 6.62 ×
J-s
so
energy = 6.62 × × 9.8360 ×
energy = 6.51 ×
J
so
energy = 6.51 × × 
kJ/mol
energy = 391.902 kJ /mol
Answer: 1 How many grams of KCl will dissolve in 1 liter of H2O at 50 °C? 5. 58.0 g of K2Cr2O7 is added to 100 g H2O at. 0 °C. With constant stirring, to what temp-. 2 34 °C? 4. How many grams of KCl will dissolve in 1 liter of H2O at 50 °C? 5. 58.0 g of ... A saturated solution of KClO3 was made with 300 g of H2O at. 34 °C.
Explanation:
You got the formulas on the sheet on the top :) So just use those, exchanging v (as in velocity, expressed in m/s) and the d (in meters) and t (in seconds). Hope you will manage it.
