Answer:The binomial nomenclature system combines two names into one to give all species unique scientific names. The first part of a scientific name is called the genus. The second part of a species name is the specific epithet. Species are also organized into higher levels of classification.
All of them are very reactive.
Answer : All Choices And Then The First Two
Answer:
Buffers are resistant to high pH changes.
Explanation:
This perfectly explains the reason why we use buffers. Buffers are substances which consist of a weak acid and its conjugate base. Buffers are resistant to significant pH changes upon addition of strong acids or bases. To illustrate this, let's say we have a buffer consisting of 0.1 mol of HF, a weak acid, and 0.1 mol of NaF (fluoride is a conjugate base of HF).
- Let's say we add some strong acid, in a general form, this acid would be represented as . In this case, conjugate base will react and neutralize it to produce some amount of HF: .
- Similarly, if we add some strong base , the acidic component will react with it to produce some amount of conjugate base: . The ratio of HF to NaF in this case is held around the same value for addition of small amounts of strong acids/bases, so pH is kept almost constant, while in neutral water, pH would drastically increase or decrease.
It’s the measure of spaces between objects. It affects groundwater infiltration by having more water fill the spaces between it. For example, is you have bigger rocks the spaces between it are bigger therefore the groundwater infiltration rate is faster. If the rocks are smaller, they are tightly packed and it’s not easy for groundwater infiltration.
