Answer:
The correct answer is - valid.
Explanation:
In this case, there is consistency in the results measures in the experiment which makes this method reliable. The consistency of a measure is referred to the reliability.
It is also given that the level of contamination of individual containers as per the average parameter of the contamination of large containers which makes this method not valid as the measurement method is how correctly it measures the true value of the parameter.
Thus, the correct answer is - method is reliable, but not valid.
Answer:
Explanation:
Endo and Exo thermic are defined by what changes take place in the environment of the reaction.
If the temperature goes up, the reaction is giving up heat. It is Exothermic.
If the temperature goes down, the reaction requires heat. It is Endothermic.
In this case, the temperature went down. The reaction is Endothermic.
Use the ICE table approach as solution:
PbSO₄ --> Pb²⁺ + SO₄²⁻
I - 0 0
C - +s +s
E - s s
Ksp = [Pb²⁺][SO₄²⁻]
1.82×10⁻⁸ = s²
Solving for s,
s = <em>1.35×10⁻⁴ M</em>
<h2>Answer:</h2>
These are reactant and products of the respiration in the cells.
The complete reaction is:
C6H1206 + 602 → 6CO2 + 6H20
<h3>Explanation:</h3>
- Respiration is the chemical reaction undergoes in the ells of human body to make the energy for the body.
- It is the breakdown of glucose molecules and the use of that breakdown energy to make ATP, the energy currency of cells.
- Basically all the sugar and proteins are first converted in glucose, C6H12O6. Then this glucose molecules undergoes breakdown by a series of steps.
Molarity is moles divided by liters so do .732 divided by .975 liters.
