Explanation:
Cr=35.880/51=0.73≈0.7
P=21.076/31=0.67≈0.7
O=43.543/16=2.71
Divide each by 0.7 u get
Cr=1 ,P =1, O=4
Empirical formula is CrPO4
a) Group 2 elements have 2 electrons on their outer shell, so they form a 2+ charge.
b) they lose 2 electrons as they are transferred to the non metal.
c)They obtain this charge as when they are made into an ionic compound the 2 electrons on the outer shell are transferred to the non metal, meaning there are 2 more protons that electrons, giving it a positive charge.
hope this helps! :)
Answer:
The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement. I'm pretty sure this is right

Answer:
Species M. furo and F. catus
Explanation:
When you look at their family name, both species have -<em>lidae </em>at the end, indicating that they are more closely related.
<u>Answer:</u> The volume of solution is 1.13 L
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:
We are given:
Molarity of solution = 2.09 M
Given mass of silver nitrate = 400. g
Molar mass of silver nitrate = 170 g/mol
Putting values in above equation, we get:
Hence, the volume of solution is 1.13 L
