Answer:
The graph you make is Temperature (y-axis) as a function of time (x-axis), where the temperature is in degrees Celsius and the time in minutes.
In this graph it can be seen that the water does not appear in a linear way, but rather ascending, since as the temperature increases, the aggregation changes appear.
At one hundred degrees the water undergoes a process called BOILING and it is there that it begins to evaporate slowly over time and becomes water vapor (gaseous).
In the case of the liquid state this will be reached when the water is subjected to a heat of 0 degrees Celsius, that is why at room temperature we see it as liquid.
If the water is at a temperature lower than one and reaches zero degrees it reaches its solidification (this is what happens in our frezeer when making ice cubes)
Explanation:
The states of water aggregation are only three, and are the ones that are drawn up in said graph.
<u>Answer: </u>
The molarity of KOH used is 0.04 M
<u>Explanation: </u>
Given base used is KOH and the acid used is Acetic Acid
According to titration;
M1V1 = M2V2
Where, M1 is the molarity of acid
V1 is the volume of acid
M2 is the molarity of base
V2 is the volume of base
Given,
Volume of KOH (base) – V2 = 25 mL
Volume of acetic acid (acid) used – V1 = 200 mL
Molarity of acetic acid M1 = 0.0050 M
Substituting the values;
0.0050 × 200 = M2 × 25
M2 = 0.04 M
The molarity of KOH used is 0.04 M
Answer:
Violet is scattered most by Earth's atmosphere, but the blue cones in our eyes aren't as sensitive to it. While our red cones aren't good at seeing blue or violet light, they are a bit more sensitive to violet than our green cones.
Explanation:
Reaction equation:
Zn + 2HCl → ZnCl₂ + H₂
One mole of gas occupies 22.4 L at STP
Moles of H₂ = 112/22.4
= 5 moles
The theoretical amount of Zn needed is 5 mol
The actual amount = 5/0.85
= 5.88 moles
mass = moles x Mr
mass = 5.88 x 65
mass = 382.2 g
The answer is D.
Both theories and laws could potentially be falsified by countervailing evidence. Theories and laws are also distinct from hypotheses. Unlike hypotheses, theories and laws may be simply referred to as scientific fact.
