I assume you mean this reaction. Zn + 2HCl --> ZnCl2 + H2 2.3 moles zinc (2 moles HCl/1 mole Zn) = 4.6 moles hydrochloric acid needed ========================
Find the population of Sydney and assume each person uses 10 units per day. Multiply it out and add about 100% for industrial use. That should give a reasonable estimate. The capacity of a power supply to an area is usually reckoned as about 1 kW per person. With a population of 4 million about 4 Gigawatts of power are needed for the Sydney area, although it could be a lot more in places which use a lot of air conditioning.
LED is an acronym for Light Emitting Diode, so I assume the metal LEAD was intended. This question has been answered extremely well.
An inlet or bay with a narrow opening and a large tidal range is ideal for generating tidal power. A tidal range of at least 5 meters is typically needed to make tidal power extraction feasible.
Viruses cannot reproduce on their own. They must invade and infect other cells in order to be able to reproduce.
"Proof beyond a reasonable doubt."
The same burden of proof as is needed for any criminal trial. The allegation must be proven beyond a reasonable doubt... not ALL doubt... just 'reasonable' doubt.
Everyone.
because everyone in greek was bored and they needed entertainment! because everyone in greek was bored and they needed entertainment!
Nothing happened in that time period that needed to be showed.
None, anyone and everyone can be a poet.
Mary is modelled after Mark Twain's sister Pamela, who was eight years older than him. Twain and two of his friends were the inspiration for Tom, so it is reasonable to assume that mary was about 18. Her age is not needed because she, like her namesake the Virgin Mary, are meant to be ageless.
Not everyone but trigonometry is needed in the field of construction under certain circumstances
The standard is proof beyond a reasonable doubt.
I assume this is a multiplication? 950 × 1765 = 1,676,750 If this is not the case, then more information is needed.

A search cannot be conducted without a warrant, which cannot be obtained without evidence of reasonable suspicion. This reasonable suspicion is often referred to as probable cause.
