Yes butterflies go through photosynthesis.
The answer of this question is A
Boiling water. A phase change occurs when water boils.
The three common phases are <em>solid</em>, <em>liquid</em>, and <em>gas</em>. A <em>phase change</em> happens when one phase changes into different phase without a change in chemical composition.
When water boils, the liquid phase becomes a gas (water vapour or steam). The water does not change its chemical composition be each phase consists of water.
Thus, boiling water involves a phase change.
Mixing paint does <em>not</em> involve a phase change because it stays a liquid during all stages of the mixing.
A suspension consists of two phases, but the phases do not change into other phases.
M=n/V , 4.5=n/1.5 , (45/10). (15/10)=n , (9/2).(3/2)=n=27/4 , n=6,75
Answer:
Explanation:
Hello,
In this case, by considering the given seminormal solution, we infer it is a 0.5-N solution which means that we can obtain the equivalent grams as shown below for the 55 cc (0.055 L) volume:
Next, since sodium carbonate has two sodium ions with a +1 oxidation state each, we can obtain the moles:
Finally, the mass is computed by using its molar mass (106 g/mol)
