WILL GIVE BRAINLIEST NO FAKE ANSWERS PLEASE I WILL REPORT How many moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas?

Balanced equation: 2H2 + O2 → 2H2O

3.0 moles of water
3.6 moles of water
5.3 moles of water
7.0 moles of water

The reaction: (ch3)3cbr + oh− → (ch3)3coh + br− in a certain solvent is first order with respect to oh−. in several experiments, the rate constant k was determined at different temperatures. a plot of ln(k) vs 1/t was constructed and the slope of the line was -1.10 x 104 k with a y-intercept of 33.5. what is the value for k at a temperature of 25°c?
