3 there are three different chemical symbols on each side of the equation
Answer:
0.045 M/s
Explanation:
Given:
Initial concentration of A = 0.625 M
Final concentration of A = 0.100 M
Total time taken for the change of concentration = 11.6 seconds
The average rate of reaction is calculated as:
= 
on substituting the respective values, we get
= 
or
The average rate of reaction = 0.045 M/s
Mg(OH)2 + 2 HCl → MgCl2 + 2 H2O
(0.0500 L) x (0.500 mol/L HCl) x (1 mol Mg(OH)2 / 2 mol HCl) x (58.3197 g Mg(OH)2/mol) = 0.729 g = 729 mg Mg(OH)2
<span>(729 mg Mg(OH)2) x (5.00 mL / 400 mg) = 9.11 mL milk of magnesia</span>
Answer:
A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations
