Question

Латунь - це сплав міді з іншими металами. До її складу входить марганець, залізо, амюміній, цинк та мідь у відношенні 1:2:3:11:33 відповідно. Яка маса латуні, якщо в ній цинку на 24 кг більше, ніж алюмінію? Яка температура плавлення латуні? Помогите срочно плиииииииииииииииииииииииииииииииииииииииииииииииииииииииииз

Answer 1

Ответ:

150кг

про температуру плавления не знаю, это уже вопрос к физикам, но если верить интернету в среднем 915°

Пошаговое объяснение:

и так, выразим соотношение через х, тогда в сплаве:

марганец-1х

железо-2х

алюминий-3х

цинк-11х

медь-33х

всего в сплаве:

1+2+3+11+33=50х

из условия знаем что:

11х-3х=24

8х=24

х=3

и теперь легко найти всю массу:

50×3=150кг

Answer 2

Ответ:

Пошаговое объяснение:

1х+2х+3х+11х+33х=50х

11х-3х=24

8х=24

Х=24:3

Х=3

3×50=150г латуни

t° плавления 915

Answer 3

Composition of Brass

Brass is an alloy made primarily of copper with the addition of other metals such as zinc, manganese, iron, and aluminum. The specific composition of brass can vary depending on the desired properties and applications. In the given question, the composition of brass includes manganese, iron, aluminum, zinc, and copper in the ratio of 1:2:3:11:33 respectively.

Calculating the Mass of Brass

To calculate the mass of brass, we need to determine the mass of each metal component and then sum them up. Let's assume the mass of aluminum in the brass is x kg. According to the question, the mass of zinc is 24 kg more than the mass of aluminum.

Let's calculate the mass of zinc and aluminum: - Mass of aluminum: x kg - Mass of zinc: x + 24 kg

The total mass of brass can be calculated by adding the masses of all the metal components: - Mass of copper: 33x kg - Mass of zinc: (x + 24) kg - Mass of iron: 2x kg - Mass of manganese: x/3 kg

The total mass of brass is the sum of all these masses: - Total mass of brass = Mass of copper + Mass of zinc + Mass of iron + Mass of manganese

Now we can calculate the mass of brass.

Temperature of Brass Melting

The melting temperature of brass can vary depending on its composition. Brass is typically composed of copper and zinc, and the melting point of pure copper is around 1084 degrees Celsius, while the melting point of pure zinc is around 419 degrees Celsius.

The addition of zinc to copper lowers the melting point of the alloy, making it easier to melt. The exact melting temperature of brass will depend on the specific composition of the alloy.

Please note that the exact values for the mass of brass and the melting temperature of brass can only be determined with the specific values of the mass of zinc and aluminum provided in the question.
