2.
Explanation:
When you put the paper in a solution, it will turn blue if it is basic, or red if it is acidic. If it does not change color, it is fairly neutral.
Answer:
palisade cell due to presence of chloroplasts
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.
N⁻²2H4(l) + 2H2O⁻¹2(l) → N⁰2(g) + 4H2O⁻²(g)
N is oxidized and O is reduced
Answer:
A. 3.2L of NO
B. 4.8L of H2O
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
4NH3 + 5O2 —> 4NO + 6H2O
A. Determination of the litres of NO produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 4L of NO.
Therefore, 4L of O2 will produce = (4x4)/5 = 3.2L of NO.
B. Determination of the litres of H2O produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 6L of H2O.
Therefore, 4L of O2 will produce = (4x6)/5 = 4.8L of H2O
