Charges of ions that is formed from magnesium and fluorine has to be chosen among the given options. Concept Introduction: The neutral atom has equal number of protons and electrons. Gaining or loosing of electrons of an atom forms ion. Atoms form their ions to attain noble gas configuration. Group IA, IIA and IIIA metal atoms contain one, two or three valence electrons. These metal atoms lose their valence electrons to get noble gas configuration. Group VA, VIA VIIA non-metal atoms contain five, six or seven valence electrons. These non-metal atoms acquire electrons to get noble gas configuration. Group IVA group elements have four valence electrons. These elements gain or lose their electrons to get noble gas configuration.

Interpretation Introduction

Interpretation:

Charges of ions that is formed from magnesium and fluorine has to be chosen among the given options.

Concept Introduction:

The neutral atom has equal number of protons and electrons. Gaining or loosing of electrons of an atom forms ion.

Atoms form their ions to attain noble gas configuration.

Group IA, IIA and IIIA metal atoms contain one, two or three valence electrons. These metal atoms lose their valence electrons to get noble gas configuration.

Group VA, VIA VIIA non-metal atoms contain five, six or seven valence electrons. These non-metal atoms acquire electrons to get noble gas configuration.

Use the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pK₁ = 4.874) to calculate the quotient [A-]/[HA] at three different pH values. pH = 4.479 [A-] [HA] [A-] pH = 4.874 [HA] = pH = 5.220 [A-] = [HA]

In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16
