PLEASE HELP QUICKLY!! How many moles of NH4OH are in 0.125L of a 1.4 M solution of NH4OH?

Answers

Answer:

0.175mol

Explanation:

Molarity of a solution can be calculated thus:

Molarity (M) = number of moles (n) / volume (V)

According to the information provided in this question, volume of NH4OH = 0.125L, molarity = 1.4M

Using; Molarity = n/V

1.4 = n/0.125

n = 0.175mol

What is the heat capacity of a substance in which 1050 grams will rise in temperature from 30.4°C to 25.7°C when it absorbs 2880 joules of heat?

Answers

Answer:

0.584 J/g°C

Explanation:

Using the formula as follows;

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

According to the information in this question;

mass of substance (m) = 1050g

Initial temperature = 25.7°C

Final temperature = 30.4°C

amount of heat (Q) = 2880J

change in temperature (∆T) = (30.4°C - 25.7°C) = 4.7°C

Using Q = m.c.∆T

c = Q ÷ m∆T

c = 2880 ÷ (1050 × 4.7)

c = 2880 ÷ 4935

c = 0.584 J/g°C

The specific capacity of the substance is 0.584 J/g°C.

Answers

Answer:

0.320 g Cu.

Explanation:

Hello there!

In this case, case, according to the presented chemical reaction, it is possible to determine that the mole ratio of zinc to copper is 1:1 and therefore, we will have the same amount of atoms for the both of them. Moreover, since one mole of copper contains 6.022x10²³ atoms of this element, with a mass of 63.546 g (molar mass); it is possible for us to write up the following mathematical setup in order to calculate the produced grams of copper:

[tex]3.03x10^{21}atoms Zn*\frac{1atom Cu}{1atom Zn}*\frac{1molCu}{6.022x10^{23}atoms Cu}*\frac{63.546gCu}{1molCu} \\[/tex]

Thus, the numerical result turns out to be:

0.320 g Cu

Round your answer to two decimals.
Please i need this asap

Answers

Since AlBr3 is the sole product, we can use its coefficient to determine its molar ratio with Al. Conveniently, that ratio is 2:2 or, simplified, 1:1, which means that the number of moles of AlBr3 produced is equivalent to the number of moles of aluminum consumed in the reaction.

We must determine the number of moles of AlBr3 produced; we are given the mass of AlBr3 produced, so we divide the mass by the molar mass of AlBr3:

(15.0 g)/(266.694 g/mol) = 0.05624 mol AlBr3

Since the molar ratio of AlBr3:Al is 1:1, that means 0.05624 moles of Al were reacted. Now, all that is left is to convert the number of moles of Al to grams. We multiply the number of moles by the molar mass of Al:

(0.05624 mol)(26.982 g/mol) = 1.52 grams Al.

So, if 15.0 grams of AlBr3 are produced in this reaction, 1.52 grams of Al are needed.

You know the number of moles of Mg that react: 6 moles.

You don't know (yet) how many moles of Mg₃N₂ are produced when 6 moles of Mg react.

The coefficients of each substance in the chemical equation tells us the molar ratio between the substances. The coefficient of Mg is 3, and the coefficient of Mg₃N₂ is 1 (coefficients of 1 are implied and omitted). So, for every 3 moles of Mg that react, 1 mole of Mg₃N₂ is produced.

We can use the proportion set up in the image to calculate the number of moles of Mg₃N₂ produced. In the first fraction, the green-boxed numerator should be our known number of moles of Mg, that is, 6 moles Mg. In the second fraction, we insert our molar ratio. Since we want the product of these two fractions to have the units "moles Mg₃N₂," the numerator in the second fraction should be 1 mole Mg₃N₂ and the denominator should be 3 moles Mg.

Our setup should look like this:

[tex]\frac{\textrm{6 moles Mg}}{1} \times \frac{\textrm{1 mole }\mathrm{Mg_3N_2}}{{\textrm{3 moles Mg}}} = \textrm{2 moles }\mathrm{Mg_3N_2}.[/tex]

Indeed, 2 moles of Mg₃N₂ are produced.

Answer:

2 moles of Mg₃N₂ are produced.

La capacidad calorífica del aluminio es de 0.9 J/g C. Determine la energía necesaria calentar un bloque de aluminio de 850 g de 22.8 grados a 94.6 grados Celcius.

Answers

Answer:

La energía necesaria para calentar el bloque de aluminio es 54927 J.

Explanation:

Se denomina calorimetría a la medición y el cálculo de las cantidades de calor que intercambia un cuerpo o un sistema.

De esta manera, entre el calor y la temperatura existe una relación de proporcionalidad directa (Dos magnitudes son directamente proporcionales cuando existe una constante de manera que cuando una de las magnitudes aumenta, la otra también; y lo mismo ocurre cuando alguna de las dos disminuye.). La constante de proporcionalidad depende de la sustancia que constituye el cuerpo como de su masa, y resulta el producto del calor específico por la masa del cuerpo. Entonces, la ecuación que permite calcular intercambios de calor es:

Q=c*m*ΔT

Donde Q es el calor intercambiado por un cuerpo de masa m, constituido por una sustancia de calor específico c y donde ΔT es la variación de temperatura.

En este caso:

c= 0.9 [tex]\frac{J}{g*C}[/tex]m= 850 gΔT= Tfinal - Tinicial= 94.6 C - 22.8 C= 71.8 C

Reemplazando:

Q= 0.9 [tex]\frac{J}{g*C}[/tex]*850 g* 71.8  C

y resolviendo se obtiene:

Q= 54927 J

La energía necesaria para calentar el bloque de aluminio es 54927 J.
