Explanation:
The answer is prokaryote :)
B: Nitric Acid is the answer you are looking for.
Answer:
Explanation:
Moles of sodium
=

⋅
g
22.99
⋅
g
⋅

.
Now you have the stoichiometric equation:
2
N

(
s

+
2
H

O
(
l
)
→
2
N

(

+
H

If there are
5.65
⋅
m
o
l
of metal, clearly
5.65
⋅

2
dihydrogen gas are evolved......, i.e.
2.83
⋅
m
o
l
H
2
. Typically, in a question like this, you would also be asked to calculate the volume the gas occupies under standard conditions, and the
p
H
of the resultant solution (would it be high, low, neutral?).
Hello,
I believe the answer is C. A and B say that it would help to change it but when we think about it data and opinions are not what people use to change a curriculum or program. Mainly they use surveys, which they didn't use here. Option D doesn't make any sense, data doesn't complement a program it supports some sort of theory which leads us to C. C is the only option where they use the data for effectiveness. Hope this helps!
