Finding chemical formulae from a mole ratio An unknown compound has the following chemical formula: where \( x \) stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 5.4 mol of nitrogen and 10.84 mol of oxygen. Write the complete chemical formula for the unknown compound.

Solve the equation and check the solution. \( y-9=0 \) \( y=\square \) (Simplify your answer.)

Simplify each side of the equation when possible. Then solve the equation and check the solution. \( c=5=-4+5 \)

Test the following equation for symmetry with respect to the \( x \)-axis, the \( y \)-axis, and the origin. \( y=x^{2}+5 \) Select all that apply. \( \square \) A. Symmetric with respect to the \( x \)-axis. \( \square \) B. Symmetric with respect to the \( y \)-axis. \( \square \) C. Symmetric with respect to the origin. \( \square \) D. None of these.
