Answer:
and how do we know this is not a virus
Explanation:
sorry dude im just saying
Sister chromatids are two identical copies of a single chromosome that are connected by a centromere. They occur as a result of a chromosome that duplicated during the S phase of the cell cycle.
Almost all catalysts work by lowering the activation energy of the reaction with no change in the free energy of the reaction
- So in this case we can say that palladium reduce automobile pollution by catalyzing the reaction between un-burned hydrocarbons and oxygen :
D. by decreasing the activation energy
Answer:
pH = 8.25
Explanation:
The acidity or basicity of a solution is measured by its pH. The pH scale ranges from 0 to 14. Solutions having pH from 0-6.9 are considered acidic, at 7 neutral and basic when ranging from 7.1-14.
pH is calculated as,
pH = - log [H⁺] ---- (1)
Where;
[H⁺] = concentration of Acid
Also, for bases pH i calculated using following formula,
pH = 14 - pOH
Therefore, Putting value of H⁺ in equation 1,
pH = - log [5.6 × 10⁻⁹]
pH = 8.25
The solution provided is basic in nature.
