What effect does the pH of water have on radish seed germination?”​

Chemistry

yuradex [85]3 years ago
3 0
Even though the radishes watered with a 5.6 pH grew the best, they did not turn out to be the healthiest. The 7 pH radishes grew the most thick and sturdy. In conclusion, radishes watered with a low pH level do not grow to be tall and radishes watered with an exact acid level to neutral grow to be tall.

Alkenes are ______.<br><br> Saturated<br> Unreactive<br> Single bonds<br> Very reactive
Aleksandr [31]
Answer:
            Alkenes are <u>Very Reactive</u>.

Explanation:
                   Other options are incorrect because;

Saturated compounds are those hydrocarbons which contains only single bonds, while alkenes contain atleast one double bond.

Single bonds again stands for saturated compounds, hence it is false.

Alkene are reactive because the double bond has the potential to open by addition reaction. So electrophiles are readily added across double bond. This reactivity can also be explained by the exposure of nucleophilic double bond above and below the plane, which is highly exposed to incoming electrophiles.

What are the 5 parts of an atom?
saul85 [17]
N the nucleus, there are protons and neutrons. That's two parts. 

<span>Outside the nucleus, there are electrons. That's a total of three parts and that is all that chemists discuss. Theoretical physicists talk about other sub nuclear "parts", but if you include them, the number goes way over 5. </span>

<span>The "shells", "sub-shells", "orbits", "orbitals", "probabilities" and the like are not physical parts, but only descriptions of energy</span>

You have an atom represented by X (not real by the way). X has 2 valence electrons. You have another atom Y that has 5 valence e
BabaBlast [244]

The chemical formula : X₃Y₂

<h3>Further explanation  </h3>

The noble gas element is a stable class of elements. The noble gas element is monatomic. Stability of noble gases is caused by an electron configuration that has a stable configuration of 8 (has 8 valence electrons) except He with a duplet configuration (has 2 valence electrons)

Other elements that do not yet have electron configurations such as noble gases will try to achieve their stability by forming bonds between elements.

This is generally called the octet rule

X has 2 valence electrons.to achieve stability, element X will release 2 electrons to form X²⁺

Y has 5 valence electrons, to achieve stability, the element Y will attract/ add electrons to form Y³⁻

The two compounds will form a compound with the charges crossed : X₃Y₂
