I think unbalanced? not sure sorry
Answer:
A mushroom is a heterotroph.
Explanation:
Mushrooms are fungi, which are heterotrophs because they depend on other organisms for their food.
Answer: 4.21×10⁻⁸
Explanation:
1) Assume a general equation for the ionization of the weak acid:
Let HA be the weak acid, then the ionization equation is:
HA ⇄ H⁺ + A⁻
2) Then, the expression for the ionization constant is:
Ka = [H⁺][A⁻] / [HA]
There, [H⁺] = [A⁻], and [HA] = 0.150 M (data given)
3) So, you need to determine [H⁺] which you do from the pH.
By definition, pH = - log [H⁺]
And from the data given pH = 4.1
⇒ 4.10 = - log [H⁺] ⇒ [H⁺] = antilog (- 4.10) = 7.94×10⁻⁵
4) Now you have all the values to calculate the expression for Ka:
ka = 7.94×10⁻⁵ × 7.94×10⁻⁵ / 0.150 = 4.21×10⁻⁸
Answer:
they causes climate change by trapping heat and also they contribute to respiratory diseases from smog and air pollution
The question is incomplete, the complete question is shown in the image attached
Answer:
3-isopropyl-1-hexyne
Explanation:
Organic compounds can be named from the structure of the compound. The name reveals the arrangement of atoms and bonds in the molecule.
If we look at the compound in the question, we will notice that the parent chain contains six carbon atoms, the triple bond is located at position 1 and the isopropyl substituent is attached to carbon 3.
Hence the proper name of the compound becomes, 3-isopropyl-1-hexyne.
