Answer:
- <u><em>The solution would be unsaturated.</em></u>
Explanation:
The data are garbled and difficult to decipher so i have to work with other data.
I will use the graph attached.
There, I have drawn two red lines that intersect at T = 60ºC and Solubility close the the middle point between 80 and 90 g/100g of H₂O, but a little bit above (closer to 90 than to 80 g/100g of H₂O).
That means that the solubility at 60ºC is close to 85g/100g of H₂O but a little bit above.
Then, if 85 g of KBr were dissolved in 100g of water at 60°C, the solution would be unsaturated: it can dissolve a little bit more of solute.
To understand how you use the solubility curve graphs:
For a given temperature:
- move vertically upward from the mark of the temperature, i.e. 60ºC, in this case.
- Intersect the curve that corresponds to your solute, i.e. KBr in this case
- Points on the line mean the solution is saturated.
- Points below the line correspond to unsaturated solutions
- Points above the line correspond to supersaturated solutions.
Answer:
ZnSO4 + H2
Explanation:
Zn + H2SO4
ZnSO4 + H2 - since there is only one on the left side, H2 is left by itself.

Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Law of multiple proportion:
When two elements combine to form two or more compounds with different proportions, the weight of on element that combine with other elements in fixed proportion is in the ratio of small whole number.
For example:
Consider the example of carbon dioxide and carbon monoxide.
CO and CO₂
we are given with 1 g carbon on both case while 1.3 g oxygen for carbon monoxide and 2.6 for carbon dioxide. It means the ratio of oxygen is 1:2.
There is 1.3 g of oxygen in carbon monoxide for one g of carbon while in case of carbon dioxide there is 2.6 g of oxygen for one gram of carbon.
You would observe, trying to identify if there's a minimum difference in each beaker. Like, colour, or using an <em>bagueta </em>(idk how to say it in english), churning it or something like that.
Answer:
see below
Explanation:
the charge of the atom is neutral because there are equal numbers of protons and electrons in an atom.
