Answer: Option (b) is the correct answer.

Explanation:

A compound is defined as the substance in which different atoms chemically combine together in a fixed ratio by mass.

For example, $Ca(NO_{3})_{2}$ is a compound as here both calcium ion and nitrate ion chemically combine together.

A compound can be broken down into its constituent particles.

Whereas an atom is the smallest particle present in a substance. It is indivisible in nature.

A molecule is a substance that contains either same or different atoms which are chemically combined together.

For example, $Cl_{2}$ , $H_{2}O$ etc are molecules.

An element is a substance that consists of only same type of atoms.

For example, aluminium element will consists of only aluminium atoms.

Thus, we can conclude that compound is the most specific classification of $Ca(NO_{3})_{2}$ .

180m/173 Tl -> 180/173 Tl + ? Express your answer as a nuclear equation

Law Incorporation [45]

Answer: The nuclear equation is $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$ .

Explanation:

A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.

For example, $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$

Here, energy is radiated in the form of gamma radiation.

Thus, we can conclude that the nuclear equation is $^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma$ .

Un anillo, de masa 90 gramos, contiene 59,1% de oro. ¿Cuál es el valor del anillo si cada mol de oro vale S/.1800?. Considere el

LekaFEV [45]

Answer:

S/.486 es el valor del anillo

Explanation:

Para hallar el precio del anillo se deben encontrar las moles de oro que contiene este.

Si el anillo es de 90g y solo el 59.1% contiene oro, la cantidad de oro en gramos es:

90g × 59.1% = 53.19g Oro en el anillo

Ahora, para convertir los gramos de oro a moles se debe usar la masa atómica del oro (197g/mol), así:

53.19g × (1mol / 197g) = <em><u>0.27 moles de oro contiene el anillo</u></em>.

Ya que cada mol de oro cuesta S/.1800, 0.27 moles de oro (Y por lo tanto, el anillo) costarán:

0.27mol × (S/.1800 / 1mol oro) =

<h3>S/.486 es el valor del anillo</h3>

Consider the reaction between iron (III) oxide, Fe2O3 and carbon monoxide, CO. Fe2O3 + 3CO --> 2Fe + 3CO2 In the process, 213

s344n2d4d5 [400]

To calculate the mass of Fe formed in a) we get first the limiting reactant between Fe2O3 and CO. Given the masses, the ratio of Fe2O3 is 1.33 while that of CO is 1.67. Hence the limiting reagent is Fe2O3. The mass of Fe formed is 148.98 grams. In b, the needed CO is only 112.04 grams. Hence, the excess is 27. 96 grams.
