Write the following number using decimal notation: seven and forty-three thousand fifty-two millionths. Converting Decimals to Fractions Note that each of the decimals you have encountered thus far in this activity end after a few digits. Decimals such as these are referred to as terminating decimals. When a terminating decimal is written as a fraction or mixed number, the denominator corresponds to the place value of the rightmost digit in the decimal. This leads to the…

NetID: Name: 8. What is [NO] and [CO₂] (in M to two decimal places) at equilibrium for the following reaction at 227 °C if the initial concentrations of each reactant is 1.25 M? Explain the validity of your final answer using chemical intuition. NO₂(g) + CO(g) = NO(g) + CO₂(8) -224.09 kJ mol-1 K(227 °C) = 6.9x105 A: [NO] = 1.25; [CO₂] = 1.25
