Answer:
A. R represents chemical energy; P represents thermal energy.
Step-by-step explanation:
The molecules in the gas contain chemical energy (R).
When the gas burns, the chemical energy is released as heat, or thermal energy (P).
The number of transferred electrons to form the ionic bond in one formula unit of each compound is as below
NaCl = 1 electron
CaS = 2 electrons
BaO= 2 electrons
KBr=1 electrons
LIF = 1 electron
explanation
ionic bond is formed between a metal and a nonmetal . This bond is formed when electron are transferred between cation and anion. To know how many electrons transferred you look the oxidation state of the metal.
for example
in NaCl only one electrons is transferred since Na is in oxidation state of +1. Na donate the one electron to Cl to form an ionic bond. Ba is in oxidation state of 2+ and hence it donate the two electrons to O to form ionic bond.
Use conversion factors to calculate this answer. Since there are 1000 ml in a liter, this means that there is 95 mg of glucose in 0.1 liter. To add on, since there is 1000 mg in a gram, this means that there is 0.095 grams in 0.1 liters. 5 liters of blood is 0.1 x 50 = 5.0. Hence, you would need to multiply 0.095 x 50, which is equates to about 4.75 grams of glucose in 5.0 liters of blood.
Don’t forget the significant figures, 4.75 is rounded to 4.7 because the significant figures in this case is 2 sig figs (5.0 liters of blood).
The temperature of internal organs of a dead body and the environmental temperature at the scene of death are important to consider in determining the time of death.
Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out
