What is the charge on the chromium ion CrCl3?
Answer: CHROMIUM ION WILL HAVE +3 CHARGE.
What is the charge of Mn in mno2?
-4
Since there are 2 oxide ions, the total oxidation number for the oxide is -4 . Since the sum of the oxidation numbers must be 0 , the oxidation number of the manganese cation is +4 .
Is CrCl3 ionic or covalent?
AlCl3, aluminum chloride; CrCl3, chromium(III) chloride; ICl3, iodine trichloride; AlCl3 and CrCl3 are ionic compounds following the rules for naming ionic compounds. The major difference is that CrCl3 contains a transition metal (Cr) which generally exhibits two or more stable charges when in ionic compounds.

Can you write down equation for line in R3 your 3?
As we saw in the previous section the equation y = mx+b y = m x + b does not describe a line in R3 R 3, instead it describes a plane. This doesn’t mean however that we can’t write down an equation for a line in 3-D space. We’re just going to need a new way of writing down the equation of a curve.
How to write down the equation of a line?
Write down all three forms of the equation of the line. To do this we need the vector → v v → that will be parallel to the line. This can be any vector as long as it’s parallel to the line. In general]
How to find the Cartesian equation of a line?
Substituting these values in the vector equation of a line passing through a given point and parallel to a given vector and equating the coefficients of unit vectors i, j and k, we have, This gives us the Cartesian equation of line. Let us consider that the position vector of the two given points A and B be and with respect to the origin.
When do you write down the symmetric equations of the line?
This is called the symmetric equations of the line. If one of a a, b b, or c c does happen to be zero we can still write down the symmetric equations. To see this let’s suppose that b =0 b = 0. In this case t t will not exist in the parametric equation for y y and so we will only solve the parametric equations for x x and z z for t t.
