Answer:
34g of potassium chlorate.
Explanation:
A saturated solution is a solution that, under a temperature, has the maximum amount of solute possible. The maximum amount that a solvent can dissolve of a solute is called <em>solubility.</em>
<em> </em>
The solubility of potassium chlorate in water at 70°C is 34g/ 100g of water.
That means, to saturate 100g of water at 70°C you need yo add:
<h3>34g of potassium chlorate.</h3>
Answer:
Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary. ... In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed.
Answer:
<h2>
2 is the coefficient of CO₂</h2>
Explanation:
The <u>coefficient</u> is the number in front of a substance that indicates how many molecules or atoms are. For example, when we see 5He, it shows that there are 5 atoms of helium. When we see 5H₂O, it indicates that there are 5 molecules of water, each having 2 atoms of hydrogen and 1 atom of oxygen, so a total of 10 hydrogen atoms and 5 oxygen atoms.
Answer:
1.4% salt residue
Explanation:
Mass percent can be found using the formula:
mass of solute (grams)
------------------------------------ x 100%
mass of solution (grams)
Therefore, since you have been given the weights of both the solute and solution, you can use the formula to solve for the mass percent.
3.50 g salt residue
----------------------------- = 0.014 x 100% = 1.4% salt residue
250 g salt solution
It can absorb thermal energy without a large change in temperature.
