The two
Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (
electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the
Nucleophilicity of nucleophile i.e. Alcohols.
Answer:
b
Explanation:
even if the skunks are gone it doesn't affect the population of the coyote
Reaction
2AgNO₃ + Cu ⇒ Cu(NO₃)₂ + 2Ag
mol silver (Ag): 95.3 : 108 g/mol = 0.882
mol copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441
mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants
mol Cu = 0.441
mass Cu = 0.441 x 63.5 g/mol = 28 g
mol AgNO₃ = 0.882
mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g
Answer: There are two elements actually and those elements are Carbon and Silicon

Answer:
0.0102moles CaCl₂.2H₂O
0.0102moles CaCl₂
Explanation:
To convert moles to grams or vice versa of a compound, it is necessary to find molar mass of this substance.
For the CaCl₂.2H₂O:
This is the calcium chloride dihydrate (Because there are 2 molecules of water). That means you have 1 atom of Ca, 2 atoms of Cl, 4 atoms of H and 2 atoms of C. <em>Molar mass is the algebraic sum of the atomic weights that compose the molecule. </em>
Molar mass:
Ca: 1ₓ40.08g/mol = 40.08g/mol
Cl: 2ₓ35.45g/mol = 70.90g/mol
H: 4ₓ1.01g/mol: 4.04g/mol
O: 2ₓ16g/mol: 32g/mol.
40.08 + 70.90 + 4.04 + 32 = <em>147.02g/mol</em>
By using the molar mass of the susbtance, 1.50g are:
1.50g ₓ (1mol / 147.02g) =
<h3>0.0102moles CaCl₂.2H₂O</h3>
In the 1.50g of CaCl₂.2H₂O you have 0.0102 moles. As you can see, 1 mole of the dihydrate substance contains 1 mole of CaCl₂. Thus, you have:
<h3>0.0102moles CaCl₂</h3><h3 />
