A 1.00 liter solution contains 0.45 M nitrous acid and 0.59 M sodium nitrite. If 0.150 moles of calcium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of calcium hydroxide.)
TrueFalse A. The number of moles of HNO2 will decrease. TrueFalse B. The number of moles of NO2- will remain the same. TrueFalse C. The equilibrium concentration of H3O+ will increase. TrueFalse D. The pH will increase. TrueFalse E. The ratio of [HNO2] / [NO2-] will increase.

24 points and brainliest to anyone who can answer under 10 minutes with best ! the table below shows the role of different substances during photosynthesis. substance role during photosynthesis glucose stores chemical energy water combines with glucose to form carbon dioxide chlorophyll traps sunlight which of the following statements would correct one of the roles listed in the table? glucose combines with carbon to form water. chlorophyll reacts with light to produce carbon dioxide. water combines with carbon dioxide during photosynthesis. chlorophyll stores chemical energy needed for photosynthesis.

Acompound has a molar mass of 92.02 grams/mole, and its percent composition is 30.4% nitrogen (n) and 69.6% oxygen (o). what is its molecular formula? a. n2o4 b. no2 c. n2o d. n4o2

Can you me with this i really appreciate it
