Answer:
53 cm³
Explanation:
When the student used dilute sulfuric acid, the reaction was complete after 60 s, because no more hydrogen was formed in the next 10 s.
The reaction would go faster if the student used a more concentrated acid, but 53 cm³ of hydrogen is the most that would form.
Answer:
Mass of liquid: 20.421g
Density= 1.0109405940594 g/mL
Explanation:
Mass of liquid
To find mass of liquid you take the mass of beaker + liquid (171.223g) and subtract it from the Mass of beaker (beaker without the water). The difference is the answer.
171.223g - 150.802g = 20.421g
Density
To find density you use the formula Mass/Volume. Take the Volume given, and the mass of the liquid you just found.
20.421mL/20.421g = 1.0109405940594 g/mL
Answer:
Pi bond
Explanation:
Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.
The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.
