Answer: THE ANSWER IS D
Explanation:
an alcohol is a hydrocarbon chain with an hydroxyl group (OH)
A, B, AND C ARE ALL ALCOHOLS, SO THE ANSWER IS D
Answer:
She should take one
Explanation:
because it is the closest option to 1.04 and if you dont have the right dosage then you always want to take the smaller dose as opose to a bigger dose

= 1.3428
check if question is correct or not
Explanation:
Answer:
Reaction 1 is balanced but 2 is not balanced , the balance equation are :
1. ![CH_{3}COOH(aq) + NaHCO_{3}(aq)\rightarrow CO_{2}(g) + H_{2}O(l) + CH_{3}COONa(aq)](https://tex.z-dn.net/?f=CH_%7B3%7DCOOH%28aq%29%20%2B%20NaHCO_%7B3%7D%28aq%29%5Crightarrow%20CO_%7B2%7D%28g%29%20%2B%20H_%7B2%7DO%28l%29%20%2B%20CH_%7B3%7DCOONa%28aq%29)
2.![CaCl_{2}(aq) + 2NaHCO_{3}(aq)\rightarrow CaCO_{3}(aq) + H_{2}O(l) + 2NaCl(aq) + H_{2}O(aq)](https://tex.z-dn.net/?f=CaCl_%7B2%7D%28aq%29%20%2B%202NaHCO_%7B3%7D%28aq%29%5Crightarrow%20CaCO_%7B3%7D%28aq%29%20%2B%20H_%7B2%7DO%28l%29%20%2B%202NaCl%28aq%29%20%2B%20H_%7B2%7DO%28aq%29)
Explanation:
Balanced Equations : These are the equation which follows the law of conservation of mass .
The total number of atoms present in reactant is equal to total number of atoms present in product.
1. ![CH_{3}COOH(aq) + NaHCO_{3}(aq)\rightarrow CO_{2}(g) + H_{2}O(l) + CH_{3}COONa(aq)](https://tex.z-dn.net/?f=CH_%7B3%7DCOOH%28aq%29%20%2B%20NaHCO_%7B3%7D%28aq%29%5Crightarrow%20CO_%7B2%7D%28g%29%20%2B%20H_%7B2%7DO%28l%29%20%2B%20CH_%7B3%7DCOONa%28aq%29)
This is acid - base type reaction where
act as Acid
act as weak base
Reactant :
,![NaHCO_{3}](https://tex.z-dn.net/?f=NaHCO_%7B3%7D)
Number of atoms of :
C = 2 (
) + 1 (
)
= 2 + 1
= 3
H = 4(
) + 1 (
)
= 4 + 1
5
O = 2(
) + 3 (
)
= 5
Na = 1 (
)
= 1
Product :
,
, ![CH_{3}COONa(aq)](https://tex.z-dn.net/?f=CH_%7B3%7DCOONa%28aq%29)
Number of atoms :
C = 1(
) + 2(
)
= 1 + 2
= 3
H = 2(
) + 3(
)
= 2 + 3
= 5
O = 1(
) + 2(
)
+2(![CO_{2}(g)](https://tex.z-dn.net/?f=CO_%7B2%7D%28g%29)
= 1 + 2 + 2
= 5
Na = 1(![CH_{3}COONa(aq)](https://tex.z-dn.net/?f=CH_%7B3%7DCOONa%28aq%29)
= 1
Number of Na =1 , C = 3 , H= 5 and O =5 in both reactant and product , so it is a balanced reaction
2.
This is double displacement reaction .
Check the balancing in both reactant and products should be :
Na = 2
H = 2
Ca = 1
C = 2
O = 6
Cl = 2
