Which of these is the correct Lewis dot structure for LiCl.

The number of molecules in the 8 grams of oxygen gas is equal to 1.506 × 10²³.

The Avogadro constant is denoted [tex]N_A[/tex] and is the proportionality factor that is the number of constituent particles such as atoms, or ions in one mole of a substance.

Avogadro's number is a constant with a numeric value of 6.022 × 10²³ reciprocal moles. Avogadro's number is named by scientist Stanislao Cannizzaro after the Italian scientist Amedeo Avogadro.

Given, the mass of the oxygen gas = 8 g

The number of molecules of one mole of oxygen gas = 6.022 × 10²³

The molecular mass of one mole of oxygen gas = 32 g

It means 32 g of the oxygen gas has molecules = 6.022 × 10²³

Then  8 grams of oxygen gas will have molecules = (8/32) × 6.022 × 10²³

                                                                                  =  1.506 × 10²³

Therefore, the molecules of oxygen gas are 1.506 × 10²³.

Answer:

Percent error =   11%

Explanation:

Given data:

Circumference = 6.28 cm

Diameter = 1.8 cm

Actual ratio of circumference and diameter = 3.14

Percent error = ?

Solution:

Formula:

Percent error = ( measured value - actual value / actual value) ×100

Measured value:

Measured ratio of circumference and diameter = 6.28 cm/1.8 cm

Measured ratio of circumference and diameter = 3.49

Now we will put the values in percent error formula.

Percent error = (3.49 -3.14 / 3.14) ×100

Percent error =   (0.35 / 3.14) ×100

Percent error =   0.11×100

Percent error =   11%

- The molecules stick together and form a solid making ice

- By removing heat

Answer: temperature

Explanation:

If you see a hot red ball then you know the color, red, and the shape, a ball, but you don’t know it’s hot.

The property of matter that you cannot observe just by looking at an object will be temperature.

Matter can be defined as everything that has mass as well as volume (takes up space). It is pretty straightforward to illustrate that most typical objects which we deal with everyday basis possess mass as well as take up too much space.

It is known that if we look any matter , the physical appearance of any matter can be determined by its color and shape not with temperature.

Therefore, the correct answer will be option B.

Answer:

1 mole is equal to 1 moles Al, or 26.981538 grams.

Explanation:

The mass in grams of the following is required.

The mass of Al is 171.323 g.

The mass of P is 1622.8 g.

M = Molar mass of Al = 26.98 g/mol

n = Number of moles = 6.35 mol

Mass is given by

[tex]m=nM\\\Rightarrow m=6.35\times 26.98\\\Rightarrow m=171.3\ \text{g}[/tex]

The mass of Al is 171.323 g.

M = Molar mass of P = 30.97 g/mol

n = Number of moles = 52.4 mol

El volumen de alcohol contenido en una copa que se llena con 75 mL (disolución) de vino es 10.875 mL

Explanation:

El Porcentaje Volumen a Volumen o Porcentaje en Volumen (%v/v) es una medida de la concentración que  indica el volumen de soluto por cada 100 unidades de volumen de la solución. Es decir, es una medida de la concentración de una sustancia en una solución que expresa la relación del volumen del soluto con el volumen total de la solución.

El Porcentaje Volumen a Volumen de una disolución es determinada por la siguiente expresión:

[tex]v/v=\frac{volumen soluto}{volumen disolucion} *100[/tex]

En este caso:

Reemplazando:

[tex]14.5=\frac{volumen soluto}{75} *100[/tex]

Resolviendo:

[tex]volumen soluto=\frac{14.5*75}{100}[/tex]

volumen soluto= 10.875 mL
