Which of the following equations is balanced
C + 02 = 2CO
2C +202 =2CO
2C + O2 = 2CO
2C + 2O2= C2O2

2c +o2=2co

Explanation:

Check and u will see that all the elements in the left side of the chemical reaction are equal to those on the right

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
