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.

Answer:

The correct option is (a).

Explanation:

We need to find the product of given numbers.

First number = 29.5

Second number = 240

Product of two numbers = 29.5 × 240

= \dfrac{295}{10}\times 240

Zeroes from numerator and denominator get cancelled.

So,

=295\times 24\\\\=7080

Hence, the correct option is (a).

How much mass (in grams) is in a 3.25 mol sample of NH4OH?
Sergeeva-Olga [200]

Answer:

114 grams

Explanation:

1. NH4OH molecular weight: The molar mass of NH4OH = 35.0458 g/mol...

2. Convert grams-NH4OH-to-moles or moles-NH4OH-to-grams. Molecular weight calculation: 14.0067 + 1.00794*4 + 15.9994 + 1.00794.
