Answer:
1 mole is equal to 1 moles Potassium, or 39.0983 grams.
39.0983g X 4 = 156.3932
so 4 moles are in 156 grams of Potassium

The change concentration of the product of a reaction over time is best shown by line graph.
You use the vertical axis (normally y-axis) to show the concentration of the product and the horizontal axis (normally x-axis) to show the time.
In that way the several points may show a tendency that you can show as a line, and the slope of the line is the change of concentration divided by the time.
A scientist should study the side effects of her new treatments if he wants to make advances in the treatment.
Explanation:
- A scientist when creating any advancement in any treatment its the duty of the scientist to find the side effects of her new treatments.
- When a patient is suffering from skin cancer and the scientist want to upgrade the techniques for treating it , its the duty of the scientist to look after certain factors.
- The first factor should be the scientist should study the side effect first and after that the scientist should make certain tests . After making tests the scientist should study the success rate and then the scientist should move for the treatment.
Answer : The amount of heat released, -35057 J
Solution :
Process involved in the calculation of heat released :
Now we have to calculate the amount of heat released.
where,
Q = amount of heat released = ?
m = mass of water = 18 g
= specific heat of liquid water =
= enthalpy change for condensation = -40700 J/mole
Now put all the given values in the above expression, we get
Therefore, the amount of heat released, -35057 J
Answer:
the funnel with the filter paper
Explanation:
When the mixture of solution is poured through the funnel with filter paper, the liquid solution can pass through the filter paper and gets collected in the beaker (filtrate) while the solid products are too large to pass through the filter paper, so they remain on the funnel (residue).
With this tool, the solid product could be separated from the mixture.
