Answer:
C.11
Explanation:
Boron-11 makes up around 80% of all natural Boron. And, typically, the quickest way to determine the most abundant isotope of an element is to just round the atomic mass to the nearest whole number.
H^5C>4 Im pretty sure is like that
Answer:
Sr
Explanation:
because it's electronegativity is the highest.
Answer:C10H10
Explanation:
Use a balanced equation to determined quantity of carbon and hydrogen. Then use simple division to determine the empirical formula before the molecula formula
Answer:
Throughout the explanations section below you will find a description of the question.
Explanation:
(1)
- Whether a solution would be positioned inside a separative funnel, combined water, as well as solvent, disintegrate particulate caffeine. In every stage, the caffeine content incorporated relies upon the coefficient of caffeine partitioning throughout the combination of water as well as fluid.
- Thus, increasingly caffeine is taken from the solvent whenever the moment you bring additional solvent. Consequently, we separate the solvent from the single component.
(2)
- For compounds to be mixed thoroughly and separated into different layers, a shuddering mixture within the dividing funnel would be essential.
- However, it vibrates the separation funnel forcefully, restricts airflow within the funnel, which can also induce the fluid under it to burst or causing fluid to fire.
