ivanzaharov [21]3 years ago
4 0

Answer:

one in a billion

Explanation:

We have it known that Pure water is entirely made up of H2O molecules. Just 1 in 10⁹, that is a billion molecules are ionized when it is at room temperature.

The Ionization of water has this chemical equation:

H2O <--> H+ + OH-

When At equilibrium and at room temperature, we have the rate of forward reaction and the backward reaction to be very fast such that no water molecule would eventually remain ionized.

Therefore our answer is roughly one in a billion water.

Debora [2.8K]

Answer:

12.7 mol

Explanation:

<em>A chemist measures the amount of fluorine gas produced during an experiment. He finds that 482. g of fluorine gas is produced. Calculate the number of moles of fluorine gas produced.</em>

Step 1: Given data

Mass of fluorine (m): 482. g

Step 2: Determine the molar mass (M) of fluorine

Fluorine is a diatomic molecule of chemical formula F₂. Its molar mass is:

mF₂ = 2 × mF = 2 × 19.00 g/mol = 38.00 g/mol

Step 3: Determine the number of moles (n) corresponding to 482. g of fluorine

We will use the following expression,.

n = m/M

n = 482. g/(38.00 g/mol)

n = 12.7 mol

A liquid that occupies a volume of 0.820 L has a mass of 2.56 kg.
user100 [1]

Answer:

The density of this liquid is 0.320 kg/L

Explanation:

Given:

Volume of the Liquid =  0.820 L

Mass of the liquid  = 2.56 kg.

To Find:

The density of the liquid in  kg/L

Solution:

Density is the mass occupied by the substance in unit volume. This density is essential determining whether the substance floats or sinks. Greek letter(rho) is used to denote density

The equation of for density is

Density = \frac{mass}{volume}

\rho = \frac{m}{v}

where m is the mass

v is the volume

On substituting the given values

\rho = \frac{0.820 }{2.56}

\rho = 0.320 kg/L

Interpretacao gerais das praticas <br>sobre densidade de amostra solido e liquido<br>​
Savatey [412]

Answer:

O sólido tem densidade mais alta em comparação ao líquido.

Explicação:

A densidade da amostra sólida é maior do que a densidade do líquido porque há pouco espaço entre as partículas do sólido. A densidade tem relação inversa com o volume de uma substância, se uma substância ocupa mais espaço então sua densidade é menor, enquanto se a substância ocupa menos espaço então tem maior densidade. As substâncias sólidas ocupam menos espaço em comparação com as substâncias líquidas, então podemos dizer que a densidade do sólido é maior do que as substâncias líquidas.
