Bronze is a metal alloy that contains primarily copper, most commonly also contains tin, but can also be made of othe elements such as phosphorous, manganese, aluminum, or silicon. Bronze is typically 88% Copper and 12% Tin.
How long can you stretch an ounce of gold?
More than 50 miles long!!!---------After some data (see the link below): from one ounce of gold we can obtain a wire (0,000 005 in diameter) long of 62 miles.Gold is the most ductile and malleable metal.
A1.0 mL sample of seawater contains 0.00000000004g of gold the total volume of seawater is 150000000000000000000L calculate the total mass of gold present in seawater?
based on your assumed data: 4.0*10-11 gms/ml, 1000ml per L => 4.0*10-8 gms/L => 4.0*10-5 grams/1000L or 1 tonne 15.0*1019 L 4*15==60=6.0*101 1019 L *10-8 gms/L *101 => 19-8+1=12 adding powers Answer: 6.0 *1012 gms. or 6 *109Kgms = 6,000,000,000 kgms Your data may be showing too low a concentration of gold. "It's been estimated that there is a milligram of gold in a ton of seawater." One tonne (metric) tonne is 1000 litres. 4.0*10-5 grams/1000L = 4.0*10-2 milligrams/1000L = 0.04 milligrams/tonne The quote above, if correct is 1.0 milligrams/tonne or 25 times what you are showing. ----some clippings on amount of gold in seawater - I don't know if these are accurate-- There is a huge quantity of gold is seawater. But it's distributed widely - across all the oceans of all the world - and is incorporated on the atomic level. That makes it very, very hard to separate out. No one has demonstrated that it can be done economically. The concentration of gold in seawater varies from place to place, and ranges between 5 to 50 ppt (about .005 to .05 tonnes (5 to 50 kg) per km3) {It's been estimated that there is a milligram of gold in a ton of seawater.} Given that the volume of all the seas is about 1.37 billion km3 The total amount of gold in all the seas is about 7 to 75 billion kg. ------- Gold occurs in sea water to the extent of 0.1 to 2 mg/ton, depending on the location where the sample is taken. 1 cubic metre is equivalent to: * 1,000 litres -------------------- A cubic metre of pure water at the temperature of maximum density (3.98 °C) and standard atmospheric pressure (101.325 kPa) has a mass of 1000 kg, or one tonne.
What volume of 0.500m mgoh is required to neutralize 0.200l of 0.100m hcl?
Im assuming you mean Mg(OH)2 and not MgOHThe reaction between Mg(OH)2 and HCl is as follows: Mg(OH)2 (aq) + 2HCl (aq) -> MgCl2 (aq) + 2H2O (l)First the number of mole is found: n(HCl) = c × v = 0.100M × 0.200L = 0.0200mol (to 3 significant figures)Next we find the number of mole of Mg(OH)2:n(Mg(OH)2) ÷ n(HCl) = Coefficient of Mg(OH)2 ÷ Coefficient of HCl n(Mg(OH)2) ÷ n(HCl) = 1 ÷ 2 therefore:n(Mg(OH)2) = (1 ÷ 2) × n(HCl) n(Mg(OH)2) = (1 ÷ 2) × 0.0200moln(Mg(OH)2) = 0.0100mol (to 3 significant figures)Finally we calculate the volume of Mg(OH)2 reacted:v(Mg(OH)2) = n ÷ cv(Mg(OH)2) = 0.0100mol ÷ 0.500MThereforev(Mg(OH)2) = 0.0200L (to 3 significant figures) = 20.0ml (to 3 significant figures)
How much water is in gold?
A whole lot! There is a huge quantity of gold is seawater. But it's distributed widely - across all the oceans of all the world - and is incorporated on the atomic level. That makes it very, very hard to separate out. No one has demonstrated that it can be done economically. The concentration of gold in seawater varies from place to place, and ranges between 5 to 50 ppt (about .005 to .05 tonnes (5 to 50 kg) per km3) Given that the volume of all the seas is about 1.37 billion km3 The total amount of gold in all the seas is about 7 to 75 billion kg.

How many 3 digit numbers have the sum of their digits equal to 5?
**If you mean how many ways three 3-digit numbers can add up to 005, the answer depends on whether the order of the numbers matters to you: • There are 21 unique equations if the order matters (e.g., counting 001 + 002 + 002 as different from 002 + 002 + 001). • There are 5 basic combinations if the order does not matter (just looking at the groups of numbers used).

What is one half percent expressed as a decimal?
One half of a percent as a decimal is expressed as .005 Percent is out of 100 or 1 in most cases. 99 cents equal 1 dollar, so one HALF of ONE percent is .005 because one out of 100 = .01 so half of that would be .005 because .005 + .005 = .01
