Answer:
Equation of Reaction = AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)
<u>Steps:</u>
1. Find the moles of AgNO3 with formula n= Mass/Mr (molecular mass)
so you will get moles= 10.0/ 169.87 = 0.05886854654
2. Using stoichiometry you know the equation has 1 mole so the moles of AgCl are gonna be the same; therefore, you will use again the same formula.
3. moles= mass/molecular mass
0.05886854654 = x/ 143.32
You rearrange the formula to find the mass
so mass = moles x molecular mass
mass = 0.05886854654 x 143.32
mass= 8.44 grams

i) They have an outer electrons configuration as
ii) Some elements like Ne and Ar does not form a stable chemical compounds.
iii) They have a large ionization energy, He has the largest ionization energy amongst the group.
In sure u will do great and the answer will be right
Answer:
To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius).
Explanation:
Answer:
Molarity of solution is 0.0049 M
Explanation:
Molarity of a solution is the ratio of number of moles of solute to volume of solution in Liter
Number of moles is the ratio of mass to molecular weight of a compound.
Here is the solute.
448 mg of = 0.448 g of
So, 0.448 g of = moles of = 0.00245 moles of
Total volume of solution = 500 mL = 0.5 L
So, molarity of solution =
