Which statement best describes how an ionic bond forms?

5060 has three significant figures: Below is the clarification

Explanation:

Significant figures

Significant figures (also referred to as significant digits and decimal places) in a number are those digits that carry substantial meaning.

These include all digits except: leading zeros.

Guidelines for determining significant figures

1. All non-zero digits are counted as significant. For instance, the number 23 has two significant figures.

2. Zeros located between two non-zero digits are significant; for example, 202.1201 contains seven significant figures.

3. Zeros preceding the significant figures are not significant. For example,.000021 has two significant figures, with zeros being non-contributory.

4. Zeros following the significant figures are significant.

This explains why the number 5060 has three significant figures.

Answer:

Explanation:

The relationship between the new temperature scale and the absolute temperature scale is defined as follows

Aw = 2 K

for K = 273.15 (the freezing point of water on the absolute scale)

Aw = 2 x 273.15 = 546.3 K

Each division of the new scale is equivalent to half that of each division on the absolute scale

each division of the new scale is minimal.

The value of R = 8.314 J per mole per K

Here, per K corresponds to 2Aw

Hence, the value of R in the new scale = 8.314/2 J per mole per Aw

= 4.157 J per mole per Aw

k = R / N

= 4.157 / 6.02 x 10²³

= .69 x 10⁻²³

= 6.9 x 10⁻²⁴ J per molecule per Aw .
