Answer:
Equalize the changes in oxidation number Each Zn atom has lost two electrons, and each H atom has gained one electron. You need 2 atoms of H for every 1 atom of Zn. This gives us total changes of +2 and -2.
Explanation:
Hope this helps :)
pls make brainliest :P
And have an amazing day <3
Answer:
Proteins folded into pleated sheets or twisted into a helix(spiral) are considered to be _secondary_ structure proteins.
Explanation:
The secondary structure is characterized by the sequence of hydrogen connections in the peptide backbone among both amino hydrogen and carboxylic oxygen atoms. The secondary structure components usually form randomly as an intermediate until the protein pleats into its 3D tertiary framework.
The balloon will reach its maximum volume and it will burst.
Given:
- A weather balloon at sea level, with gas at 65.0 L volume, 745 Torr pressure, and 25C temperature.
- When the balloon was taken to an altitude at which temperature was 25C and pressure was 0.066atm its volume expanded.
- The maximum volume of the weather balloon is 835 L.
To find:
Whether the weather balloon will reach its maximum volume or not.
Solution:
The pressure of the gas in the weather balloon at sea level =
The volume of the weather balloon at sea level =
The temperature of the gas in the weather balloon at sea level:
The balloon rises to an altitude.
The pressure of the gas in the weather balloon at the given altitude:
The volume of the weather balloon at the given altitude =
The temperature of the gas in the weather balloon at the given altitude:
Using the Combined gas law:
The maximum volume of the weather balloon= V = 835 L
The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.

Answer:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Answer:
Therefore 9 moles of nitrogen are required to produce 18 moles of ammonia.
