Heat is needed because if you just placed copper with zinc, you'd just have a zinc coating around the copper. The composition of zinc and the composition of zinc will be separate instead of becoming one solution. The heat allows the two to bond, allowing the zinc and copper to move around, and becom…e an alloy (a solid solution) - brass. ( Full Answer )
B ronze is principally an alloy of copper and tin .. Brass is any alloy of copper and zinc .
Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.
25 is what percent of 75 = 25 / 75 = 0.333333 Converting decimal to a percentage: 0.333333 * 100 = 33.33%
NO . Yellow brass 60% COPPER 40% Zinc . RED Brass 85% Copper 15 % Zinc . Notice no ferrous metals used
To find 25 percent of a number, multiply the number by 0.25. In this instance, 0.25 x 75 = 18.75. Therefore, 25 percent of 75 is equal to 18.75.\n
How much of an alloy that is 20 percent copper should be mixed with 300 ounces of an alloy that is 60 percent copper in order to get an alloy that is 30 percent copper?
900 ounces. Since this contains 20% copper, The copper content will be 180 ounces. The original 300 ounces contain 30% copper which is also 180 ounces. Hence in the resulting mixture of 1200 ounces (300+900), the total copper is 360 ounces (180+180). Hence the copper content of resulting mixture is …360/1200 which is 30% ( Full Answer )

575 milliliters of a copper sulfate solution contains 2 percent copper sulfate how many milliliters of the solution are copper sulfate?
You will have to assume that the 2 % is a volume fraction, then the volume of copper sulfate in the solution would be 11.5 milliliter(575 ml*(0.02). If it were a weight fraction, then you would have to have more information on the solution density.
Metal alloy that is 18 percent copper how many ounces of an alloy that is 14 percent copper must be mixed with an alloy that is 23 percent copper to form 90 ounces of alloy?
The mass or weight w of the desired 18 % copper alloy may be calculated from the masses of the two kinds of distinct alloys specified to be mixed and their masses, M for the copper-rich alloy and m for the lower copper alloy, from the formula 0.23M + 0.14m = 0.18 (M + m). Furthermore, M + m is state…d to be 90, so that M = 90 - m. Therefore 0.23(90 - m) + 0.14m = 0.18 X 90 = 16.2. Multiplying out and collecting like terms results in 20.7 - (0.23 + 0.14)m = 16.2 or 0.09m = 4.5 or m = 50 ounces. M = 90 - 50 = 40 ounces. ( Full Answer )
A 16 lit water n milk mixture contains 75 percent of milk.hw many lit of watr is to b added to d mixture such dat percent of milk in new solution is 25 percent?
Your problem here probably lies in the fact that you are functionally illiterate. Nonetheless, the answer is 32 litres. 75% of 16 = 12 12/0.25 = 48. 48 - 12 - 4 (the original volume of water) = 32.
True and False. If the coin is dated 1983 and newer, it is indeed 97.5% zinc and 2.5% copper. However, if it is dated 1981 and earlier, then it is 95% copper. During 1982, the US Government decided that pennies were too expensive to make with so much copper. So they decided to use zinc, with is stro…ng and also cheaper. These newer pennies are only coated with copper. One can easily decide the content by its weight. The newer zinc pennies weigh only 2.50 grams, whereas the older copper-rich pennies weigh 3.11 grams. ( Full Answer )
300% Because you divide both sides by 25 and you will get 75/25=3. Then convert 3 into 300% by making it into a decimal, 3.00 and move the decimal place two places to the right.
This solution is 100(2.19/75) = 2.9 percent sodium chloride, to the justified number of significant digits.
Brass IS an alloy of copper and zinc Copper and zinc are pure metals (elements)
Copper and Zinc are melted down to liquid state. Then the two metals are combined in some difficult to explain process. When the liquid metal cools, the alloy Brass is formed.
Alloys that contain only copper and zinc are usually called "brass"; there are also some alloys that contain one or more other metals in addition to copper and zinc, and these usually have another name.
The metals silver, copper and nickel are elements. It is brass that is an alloy, and copper and zinc are what make it up.
How much of alloy that is 20 percent copper should be mixed with 200 ounces of an alloy that is 50 percent copper in order to get an alloy that is 30 percent copper?
LET X be the weigh tof the 20% alloy and then the total weight of the 30% alloy is 200 +X then 0.20X + .50 (200) = .30 (200 +X) .20X + 100 = 60 + .3X 40 = .1X 400 = X = 400 ounces
well they are all metal what you think. but if you take 13.6 x 2 and divide by the 4 chemical compounds of the periotic table by using newton's first law take the mass of the object and find the density of the water and make a hypothesis of where the alloys fall on the table. than you will find in… copper, brass, aluminum, lead, tin, zinc, and bronze are alloys. repeat process if not working. ( Full Answer )
It's substitutional because Copper and Zinc have close atomic radius, so they substitute each other. if one of the elements is small enough to fit between the larger atoms then it forms an interstitial .
Yes. The prefix "quart" is derived from the word for 4, so quartile always means splitting the data into 4 sections, ie. 25%, 50%, 75%, 100%.
25% of 75% = 25 / 100 x 75 / 100 = 3 / 16 = 3 / 16 x 100 % = 18.75 % .
How much of an alloy that is 10 percent copper should be mixed with 400 ounces of an alloy that is 70 percent copper in order to get an alloy that is 20 percent?
How much of an alloy that is 10% copper should be mixed with 400 ounces of an alloy that is 70% copper in order to get an alloy that is 20%
$18.75 is 25% $75 - $18.75 = $56.25 To find a percent, divide your number by 100 (to get 1%) then multiply by how many percent you need (in your case 75, as you have taken 25 away from 100)
The amount of copper and zinc in brass vary considerably depending on the type of brass. Most types of brass can be made into sheet form. Most brass is about 30-40% zinc and about 60-70% copper.
How much of an alloy that is 20 percent copper should be mixed with 100 ounces of an allo that is 60 percent copper in order to get an alloy that is 30 percent copper?
The question can be rewritten as the following equation: (20%x + 60%100)/(100+x) = 30% Where x is the amount of 20% copper you need to add. This equation can be solved by first multiplying both sides by (100+x) to get: 20%x + 60%100 = 30%100 + 30%x Now 30%100 can be subtracted from both sides 20%x …+ 30%100 = 30%x Now 20%x can be subtracted from both sides 30%100 = 10%x Now both sides can be divided by 10% 300 = x Thus you need to add 300 ounces of 20% copper alloy in order to get an alloy that totals 30% copper.

It might be because iodide and iodine is in an equilibrium: I 2 + I - -> I 3 - That way formed iodine won't escape when an excess of iodide is used.
How much of an alloy that is 40 percent copper should be mixed with 400 ounces of an alloy that is 80 percent copper in order to get an alloy that is 60 percent alloy?
Designate the weight in ounces of the first alloy, containing 40 percent copper, as w. Then, from the problem statement and the fact that percentages can be converted to decimals by dividing by 100, 0.40w + (0.80)(400) = 0.60(400 + w). Applying the usual methods of algebra, multiplying out results… in: 0.40 w + 320 = 240 + 0.60w; transposing like terms with sign change and collecting results in: (0.40 - 0.60)w = 240 -320; or -0.20 w = -80, or w = 400.
