chlorobenzene
Carbon - 6
Hydrogen - 5
Chlorine - 1
that 1 chlorine replaces one of the hydrogens
thats why hydrogen number decreases by number of Cl atoms (that are substituting those H atoms)
Answer:
58g
Explanation:
In order to solve this problem, you must take a look at the solubility graph for potassium nitrate.
Now, the solubility graph shows you how much solute can be dissolved per 100g of water in order to make an unsaturated, a saturated, or a supersaturated solution.
You're looking to make a saturated potassium nitrate solution using
50g of water at 60∘C. Your starting point will be to determine how much potassium nitrate can be dissolved in 100g of water at that temperature in order to have a saturated solution.
As you can see, the curve itself represents saturation.
If you draw a vertical line that corresponds to 60∘C and extend it until it intersects the curve, then draw a horizontal line that connects to the vertical axis, you will find that potassium has a solubility of about
115g per 100g of water. Your answer is 58g of potassium nitrate
Answer:
d = 3 g/cm³
Explanation:
Given data:
Mass of stone = 27 g
Volume of water = 10 cm³
Volume of water+ stone = 19 cm³
Volume of stone = ?
Density of stone = ?
Solution:
Volume of stone = total volume - volume of water
Volume of stone = 19 cm³ - 10 cm³
Volume of stone = 9 cm³
Density of stone:
d = m/v
d = 27 g/ 9 cm³
d = 3 g/cm³
Aluminum has a molar mass of 27. So one mole of aluminum is 27grams
Someone may think the results are wrong you can fight with them through words or the use of hands in which you can toss them
