Answer : chemical reaction
Mixing an acid with a base is a common chemical reaction.
Answer:
Explanation:
C6H12O6 is the formula of simple sugar, glucose. The primary elements in the glucose are carbon, hydrogen and oxygen. Thus, glucose belongs to the group of carbohydrate.
Carbohydrates are group of bio molecules that comprises of carbon , hydrogen and oxygen as its constituents elements. Thus all the substances that contain all three element primarily C, H and O are considered as carbohydrates.
Given:
rate = k [A]2
concentration is
0.10 moles/liter
rate is 2.7 × 10-5 M*s-1
Required:
Value of k
Solution:
rate = k [A]2
2.7 × 10-5 M*s-1
= k (0.10 moles/liter)^2
k = 2.7 x 10^-3
liter per mole per second
Answer:
Element atom molar mass Total % composition
Na 1 23 40 57.5 %
O 1 16 40 40%
H 1 1 40 2.5 %
The given compound is NaOH.
Na : number of atom= 1
Molar mass= 23 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass = 
O : number of atom= 1
Molar mass= 16 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass = 
H : number of atom= 1
Molar mass= 1 g/mol
Total mass of NaOH = 40 g/mol
% composition by mass =
