Answer:
3M
Explanation:
Molarity is one of the measures of the molar concentration of a solution, which can be calculated by using the formula below:
Molarity = number of moles ÷ volume
From the information given in this question, 4 liters of a solution contains 12 moles of sugar. This means that n = 12mol and V = 4L
Molarity = n/V
Molarity = 12/4
Molarity = 3
Hence, the molarity of the sugar solution is 3mol/L or 3M
Answer:
Carbon dioxide serves as the source of carbon,
Explanation:
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
Hope this helps :)
Answer:
Both the C and the N can participate in reactions
Explanation:
The word ambident comes from two Latin words that mean "both teeth".
An ambident group can react at two different sites to form products.
For example, the cyano group has two major resonance structures (see below).
The hybrid has two different ends, each with a lone pair and a partial negative charge.
Thus, it can react to form CH₃CN by having the C attack, or CH₃NC by having the N attack.
