Answer: a) Oak trees grow tallest between temperatures of 10 and 40 degrees
Explanation:
This hypothesis is specific, can be tested (though perhaps not easily), and is well set up.
Hope this helps! :)
Answer:
[H+] = 4.365x10⁻¹¹
Explanation:
The pH is a measurement widely used in chemistry. Is used in quality control to determine if a product is good for human or pet consumption. The equation to obtain the pH is:
pH = -log [H+]
To solve [H+]:
10^pH = -[H+]
10^-pH = -[H+]
In the problem:
10^-10.36 = -[H+]
<h3>[H+] = 4.365x10⁻¹¹</h3>
If I'm correct the answer should be a series circuit :) Hopefully this helps you out
The powder sugar because has more contact area
The oxidation number of H is -1.
Sum of the oxidation numbers in each element =
charge of the complex
CaH₂ has 1 Ca atom and 2H atoms. The charge of
the complex is zero. Let’s say Oxidation number of H is "a".
Then,
<span> (+2)
+ 2 x a = 0 </span>
<span> +2 + 2a = 0</span>
2a = -2
a = -1
Hence, the oxidation number of Hydrogen atom in CaH₂ is -1
