Respuesta:

2400 mL

Explicación:

Paso 1: Información dada

Volumen de solución: 3 L (3000 mL)

Concentración de naranja: 20 % v/v

Paso 2: Calcular el volumen de naranja

La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.

3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja

Paso 3: Calcular el volumn de agua

El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.

VSolución = VNaranja + VAgua

VAgua = VSolución - VNaranja

VAgua = 3000 mL - 600 mL = 2400 mL

What is the reason behind that the melting and boiling point of iron is more than that of sodium?

sweet [91]

Answer:

As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.

Hydrogen peroxide, H2O2, decomposes according to the equation above. This reaction is thermodynamically favorable at room temper

s2008m [1.1K]

Answer:

4H₂O₂ → 4H₂O + 2O₂

Explanation:

The chemical reaction for the decomposition of hydrogen peroxide can be represented as follows;

2H₂O₂ → 2H₂O + O₂

Therefore, two molecules of hydrogen peroxide decomposes into two molecules of water and one molecule of oxygen.

In a related diagram, we have 4 molecules of hydrogen peroxide decomposing, therefore we have;

4H₂O₂ → 4H₂O + 2O₂

The attached diagram shows the products of the decomposition of the four molecules of hydrogen peroxide.

phosporus can be prepared from calcium phosphate by the following reaction: 2Ca3(PO4)2+6SiO2+10C → 6CaSiO3+P4+10CO Phosphorite i

morpeh [17]

Answer:

285 g of P₄

Explanation:

Let's consider the following balanced equation.

2 Ca₃(PO₄)₂ + 6 SiO₂ + 10 C → 6 CaSiO₃ + P₄ + 10 CO

We know the following relations:

100 g of phosphorite contain 75 g of Ca₃(PO₄)₂
2 moles of Ca₃(PO₄)₂ produce 1 mole of P₄
The molar mass of Ca₃(PO₄)₂ is 310 g/mol

The molar mass of P₄ is 124 g/mol

Then, for 1.9 kg of phosphorite:

$1900g(phosphorite).\frac{75gCa_{3}(PO_{4})_{2}}{100g(phosphorite)} .\frac{1molCa_{3}(PO_{4})_{2}}{310gCa_{3}(PO_{4})_{2}} .\frac{1molP_{4}}{2molCa_{3}(PO_{4})_{2}} .\frac{124gP_{4}}{1molP_{4}} =285gP_{4}$
