To find the mass of hydrazine containing 1 billion hydrogen atoms, we state that , thus the mass is1.328\times 10^{-14}g

Explanation:

The molar mass for hydrazine is 32 g/mol

. Given that 1 mole of hydrazine consists of 2 moles of nitrogen atoms and 4 moles of hydrogen atoms, if we need the number of hydrogen atoms = 1.000\times 10^9

Based on the mole concept, 1 mole of a substance contains Avogadro's number of molecules.

Thus, 1 mole of hydrazine will contain a certain number of hydrogen atoms. Hence, the mass for 1 billion hydrogen atoms in hydrazine equals 32 grams.

Consequently, for 1 billion hydrogen atoms, the mass of hydrazine equates to \frac{32g}{2.4088\times 10^{24}}\times 1.000\times 10^9=1.328\times 10^{-14}g

The mass of hydrazine required to contain 1 billion hydrogen atoms is 1.3285 × 10⁻¹⁴ g

Explanation:

Given that 32 g of hydrazine (equivalent to 1 mole) contains 4 × 6.022 × 10²³ hydrogen atoms, we can set up the equation: X g of hydrazine holds 1 × 10⁹ hydrogen atoms. Thus, X = (32 × 1 × 10⁹) / (4 × 6.022 × 10²³) leads us to conclude that X = 1.3285 × 10⁻¹⁴ g of hydrazine.

A specific amount of energy is emitted when excited electrons in an atom in a sample of an element return to the ground state.Th
castortr0y [3046]
The answer is C. The specific amount of energy released when excited electrons fall back to the ground state produces an emission spectrum. That energy is emitted as photons with precise wavelengths corresponding to the energy differences between levels. Because each element yields a characteristic set of wavelengths, the emission spectrum can be used to identify the element in the sample.

Two samples of matter differ in temperature by 20°C. What is the difference in temperature of these two samples using the Kelvin
Tems11 [2777]

Answer:

The temperature difference is 293.15 Kelvin.

Explanation:

The provided information:

The temperature difference between the two matters is 20°C

We need to determine this difference in Kelvin =?

To solve this;

Using the formula:

0°C +273.15

Now substituting the values in place of 0.

20°C + 273.15 = 293.15 K

Hence, the temperature differential between the two samples is 293.15 K.

(a) The original value of the reaction quotient, Qc, for the reaction of H2(g) and I2(g) to form HI(g) (before any reactions tak
KiRa [2933]

Response:

Here's my calculation

Clarification:

Assume the starting concentrations of H₂ and I₂ are 0.030 and 0.015 mol·L⁻¹, respectively.

We need to determine the initial concentration of HI.

1. We will need a chemical equation with concentrations, so let's compile all the information in one location.

H₂ + I₂ ⇌ 2HI

I/mol·L⁻¹: 0.30 0.15 x

2. Calculate the concentration of HI

Q_{\text{c}} = \dfrac{\text{[HI]}^{2}} {\text{[H$_{2}$][I$_{2}$]}} =\dfrac{x^{2}}{0.30 \times 0.15} =  5.56\\\\x^{2} = 0.30 \times 0.15 \times 5.56 = 0.250\\x = \sqrt{0.250} = \textbf{0.50 mol/L}\\\text{The initial concentration of HI is $\large \boxed{\textbf{0.50 mol/L}}$}

3. Plot the initial values

The graph below visualizes the initial concentrations as plotted on the vertical axis.
