Answer:
784500 Joules
Explanation:
To start, you will need an equation to find the change in energy. This can be found by using 
or by using integrated heat capacities.
to find the mass of water,
1kg/L is the density of water.
Then, 
Notice that all of the units do not cancel out properly, so some unit conversions are needed to find the correct answer.
Answer:
C₃H₃NaO₂
Explanation:
The percentage composition of the artificial snow is given.
The smallest whole number ratio of the atoms in a compound gives the empirical formula.
To find the empirical formula of the artificial snow, we use the method below;
Percentage composition of oxygen = 100 - (38.3+3.33+ 24.4) = 33.97
Elements C H Na O
Percentage
Composition 38.3 3.22 24.4 33.97
Number of
moles 38.3/12 3.22/1 24.4/23 33.97/16
3.19 3.22 1.06 2.12
Divide by
the smallest 3.19/1.06 3.22/1.06 1.06/1.06 2.12/1.06
3 3 1 2
The empirical formula of the compound is C₃H₃NaO₂
Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Taste and colour of water is different in both pot and plastic bowl.
<h3>Comparison between water in pot and plastic bowl</h3>
The appearance of the water in the pot is different from that of the water in the plastic bowl because of the colour. We know that water adopt the colour of the container in which it has been kept.
The taste of water in the pot is somewhat sweeter and colder than water present in the pot due to presence of pores and composition of pot so we can conclude that taste and colour of water is different in both pot and plastic bowl.
