The molar mass (atomic weight ) of sodium is 23.0 grams/mole and the molar mass of sodium azide, NaN3 , is the mass of sodium, 23.0 gram/mole added to the molar mass of three atoms of nitrogen (14.0 x 3 = 42 gram/mole) which equals 65.0 grams/mole. The percentage of sodium is 23.0 /65.0 x 100 % = 35 %

Ordena de mayor a menor según sus radios iónicos a los siguientes iones:
I am Lyosha [343]

Answer:

The correct order of the elements, taking into account their ionic radius from highest to lowest, is:

<em>a) Cl⁻¹ > F⁻¹ > Na⁺¹ > Mg⁺²</em>

<em>b) S⁻² > O⁻² > Li⁺¹ > Be⁺²</em>

<em>c) S⁻² > Cl⁻¹ > K⁺¹ > Na⁺¹</em>

Explanation:

In ions the ionic radius is determined by the amount of electrons an element gains or loses to become an ion.  The more negative an ion is, the greater its ionic radius.

As a rule, anions (negative charge) have a larger ionic radius than cations (positive charge), because the loss of electrons means a contraction of the ionic radius, while the gain of electrons means a greater radius.

To determine which ionic radius is greater in anions or cations with the same charge, it must be considered that in the periodic table the ionic radius increases from top to bottom and from right to left.

A solution contains 1 LaTeX: \times\:×10−4 M OH– ions. Calculate the solution pH value, and determine if the solution is acidic,
docker41 [41]

Answer:

pH = 10

The solution is basic.

Explanation:

A solution contains 1 × 10⁻⁴ M OH⁻ ions. First, we will calculate the pOH.

pOH = -log [OH⁻]

pOH = -log 1 × 10⁻⁴

pOH = 4

We can find the pH of the solution using the following expression.

pH + pOH = 14.00

pH = 14.00 - pOH = 14.00 - 4 = 10

Since the pH > 7, the solution is basic.

Which instrument below is used to measure an intensive property?
Andrei [34K]

An intensive property is the physical characteristics that have an independent magnitude. The thermometer can be used to measure the temperature. Thus, option C is correct.

<h3>What is an intensive property?</h3>

An intensive property has been constituted of the parameters that are not dependent on the size and the mass of the sample. Density, pressure, and temperature are some intensive properties.

The first image shows a weighing balance, the second shows a volumetric cylinder, and the fourth shows a ruler used to measure mass, volume, and length respectively, which are extensive properties.

Therefore, option C. thermometer measures temperature, which is an intensive property.
