What is the oxidation state for 2na plus cl2?
2Na + Cl2 -> 2NaCl. The oxidation state of the sodium ion in NaCl is +1 and the oxidation state of Chloride ion is -1. Oxidation states of the elemental reactants is zero (as for all elements)
What is the chemical formula for Ca and Br?
All you have to do is flip the numbers and reduce. If you have Ca+2 and Br-, Switch the numbers so you get CaBr2. 1 and 2 do not have any common factors so you don't have to reduce! CaBr2 is the final answer.
Which element increases its oxidation number in the following reaction 2na plus 2h2o---2naoh plus h2?
Sodium - it goes from oxidation number 0 to +1
What is the oxidation numbers in PO34?
The oxidation numbers in PO43- , phosphorus oxidation number=+5; oxygen = -2
What is the sum of the oxidation numbers for P2O5?
There are two oxidation numbers. P shows +5 oxidation number.
What is the common oxidation numbers for calcium?
The only oxidation number is 2+.

What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
What is the oxidation number for Ca in Ca Br?
The molecular formula should be CBr4. The oxidation numbers are -1 for each Br, +4 for C.
How many moles of CaBr are in 5.0 grams of CaBr2?
Not many! 5.0 grams CaBr2 (1 mole/199.88 grams CaBr2) = 0.025 moles CaBr2
How many grams of CaBr2 are there in 0.31moles of CaBr2?
0,31 moles of anhydrous CaBr2 is equal to 61,966 g.
Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
