What is the approximate time of death if the body temperature was 15.6°C?

1 answer:

6 0

Answer:

This stiffening process, called Rigor Mortis, has a roughly known time of occurrence and can therefore be used to estimate time of death. In general: If the body feels warm and no rigor is present, death occurred under 3 hours before. If the body feels warm and stiff, death occurred 3-8 hours earlier.

Calcium forms ions with a charge of +2. Iodine forms ions with a charge of -1. Which of the following would represent an ionic c

astra-53 [7]

The formula that would represent an ionic compound that is composed of calcium and iodide ions is CaI2

Explanation

Ionic compound CaI₂ is formed when Calcium form cation ( <em>a positively charged ion</em>) by losing 2 electrons while two iodine atoms form anion ( <em>a negatively charged ion</em>) by gaining one electron each.

When writing down formula of ionic compound, the formula of cation is written first followed by anion formula. therefore Ca is written first followed by I.

The numeric subscript 2 after I(iodine) indicate that 2 atoms of iodine are involved in bonding.

The solubility of nacl at 30°c is 36.3 g/100 g of water. what mass of nacl is contained in a saturated solution that contains 30

sleet_krkn [62]

Because a solubility is calculated for saturated solutions we can write:

36.3 g NaCl ---100g water
x g NaCl ---- 300.0 g water

x=36.3*300/100=108.9 g NaCl
