Answer:
carbonic acid
Explanation:
Carbonic acid refers to the natural existent acid in our atmosphere which is produced when water reacts with water vapor and it makes rain naturally acid. As a result, rainwater is always acidic. On the other hand, acid rain occurs when precipitation contains a higher than normal acidity and a pH lower than 5.0.
Answer:
The ion is a monoatomic cation
The symbol of the noble gas is Krypton(Kr)
The formula of the ion is Br⁻
The law of conservation of energy states that when one
form of energy is converted into another, no
energy is destroyed in the process. The answer is letter B. Energy cannot be
created nor destroyed, it can only be converted from one form into the other.
Assuming the molar mass of oxygen is 18.01, you only need 16 grams (B) of oxygen because the molar mass of hydrogen is about 1 gram.
16+1+1=18
<span>You would need 2.5ml CHCl3 in CH3OH to a final solution volume of 100ml
Which is: 2.5*5 = 12.5ml CHCl3 in CH3OH to a final solution volume of 500ml.
Be careful: mixing liquids very often means that the volumes are not additive: It is therefore not correct to say: add 12.5ml CHCl3 to 487.5ml CH3OH.</span>
