Question

СРОЧНООО,ПОМОГИТЕ ПОЖАЛУЙСТА!!!!минерал составом x2yo5, где x y - неизвестные элементы,был обнаружен в 1798 году в Испании.В зависимости от того,под каким углом падают солнечные лучи,минерал меняет свой цвет(желто-зеленый-красновато-бурый-темно-красный)Массовая доля Х равна 33,33%,Y-В 1,93 раза меньше .Установите формулу минерала .В ответе 1 укажите только символ химического элемента Х латинскими буквами без пробелов и каких-либо знаков препинания ответ 1:___________ В ответе 2 укажите только символ химического элемента Y ОТВЕТ 2:_________

Answer 1

Ответ 1: Al
Ответ 2:Si

Answer 2

Mineral Composition and Discovery

The mineral with the composition x2Yo5, where x and y are unknown elements, was discovered in Spain in 1798. This mineral exhibits color changes depending on the angle at which sunlight falls on it, ranging from yellow-green to reddish-brown to dark red.

Determining the Formula

To determine the formula of the mineral, we need to find the values of x and y. The given information states that the mass fraction of X is 33.33%, and Y is 1.93 times smaller than X.

Let's assume the mass fraction of Y is y. According to the given information, the mass fraction of Y is 1.93 times smaller than X. Therefore, we can write the equation:

y = (33.33% / 1.93) = 17.25%

Now, we know that the mass fraction of X is 33.33% and the mass fraction of Y is 17.25%.

Mineral Formula

The mineral formula can be determined based on the mass fractions of X and Y. Since we don't have specific information about the elements X and Y, we can represent them as symbols.

Answer 1: The symbol for the chemical element X, in Latin letters and without any spaces or punctuation marks, is X.

Answer 2: The symbol for the chemical element Y, in Latin letters and without any spaces or punctuation marks, is Y.

Therefore, the formula of the mineral is XY2O5.

Please note that the specific identities of elements X and Y are not provided in the given information.
