Answer:
she should not have multiplied the sulfur atoms by the subscript 4
Explanation:
The fomula is NH4 (1+)
There are only two elements N and H.
As per oxidation state rules, the most electronegative element will have a negative oxidation state and the other element will have a positive oxidation state.
N is more electronative than H, so H will have a positive oxidation state and nitrogen will have a negative oxidation state.
You can also use the rule that states the hydrogen mostly has 1+ oxidation state,except when it is bonded to metals.
In conclusion the oxidation state of H in NH4 (1+) is 1+.
Now you must know that the sum of the oxidations states equals the charge of the ion, which in this case is 1+.
That implies that 4* (1+) + x = 1+
=> x = (1+) - 4(+) = 3-
Answer: the oxidation state of N is 3-, that is the option b.
We are given that 1 teaspoon is equivalent to 5 mL,
therefore 0.75 teaspoon is:
0.75 teaspoon * (5 mL / 1 teaspoon) = 3.75 mL
So the mass is density times volume:
mass = (12.5 mg/5 ml) * 3.75 mL
<span>mass = 9.375 mg</span>
Answer:
The temperature is 298.5 K, which corresponds to 0.50°C.
A jacket would be appropriate clothing for this weather.

Answer:
N-terminal Phe, C-terminal Ser
Explanation:
Amino acids connect like
NH2 -CH(R1) -CO -NH-CH(R2)-CO-.....-NH-CH(Rn)COOH
So, 1st amino acid is N -terminal , and it is Phe.
Last amino acid is C- terminal, and it is Ser.
