Answer:
a) 65.74 = 4 significant figures
b) 60.009 = 5 significant figures
c) 66_ = 2 significant figures
d) 65.750 = 5 significant figures
Explanation:
Significant figures or digits is defined as the total number of digits in a number that have meaning and contribute to the precision of the given number.
a) 65.74 = 4 significant figures, all the non-zero figures are considered significant.
b) 60.009 = 5 significant figures, zeros present between non-zero figures are significant.
c) 66_ = 2 significant figures, all the non-zero figures are considered significant.
d) 65.750 = 5 significant figures, all the non-zero figures and the trailing zero after the decimal are significant.
Answer:
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous reacts to form a dilute mixture solution of (carbonic acid ).
The reaction is
This is a forward reaction. And the symbol shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
Hey There!:
Molar mass O2 => 32.0 g/mol
Molar mass Cl2 => 71.0 g/mol
effusion rate α 1 / (√ molar mass )
E Cl2 / E O2 = √ molar mass O2 / √ molar mass Cl2
E Cl2 / E O2 = ( √ 32.0 ) / ( √ 71.0 )
=> 0.671
Hope that helps!
