<h3><u>Answer;</u></h3>

K2SO4 - KOH and H2SO4

NaBr - NaOH and HBr

<h3><u>Explanation;</u></h3>
  • Salts are compounds that contain positively charged ions and negatively charged ions. That is; they consist of the positive ion of a base and the negative ion of an acid.
  • Salts may be produced when acids and bases are combined together in equal proportions, a process called neutralization.
  • During neutralization reactions an acid reacts with a base to form a salt and water as the only products.

Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH3(CH2)12COOH], palmitic acid [CH3(CH2)14COOH], and ol
Sergio039 [100]

Answer:

The triglyceride made from glycerol, myristic acid, palmitic acid and cis-oleic acid is shown in the attached pictures.

Explanation:

A triglyceride or triacylglyceride is an ester derived from glycerol and three fatty acids. The fatty acids of this exercise are myristic acid, palmitic acid and oleic acid.

A fatty acid is a biomolecule of lipid nature formed by a long linear hydrocarbon chain, of different length or number of carbon atoms, at the end of which is a carboxyl group.

The myristic acid has a carbon chain of 14 carbon atoms with a carboxyl group at one end.

Palmitic acid has a carbon chain of 16 carbon atoms with a carboxyl group at one end.

Oleic acid has a carbon chain of 18 carbon atoms with a carboxyl group at one end and a double bond at position 9.

Triglyceride is formed by the esterification of the glycerol oxidrile group and the carboxyl acid group.

When the volume of a gas is changed from 3.6 L to 15.5 L, the temperature will change from oC to 87°C
klio [65]
The answer:
<span>When the volume of a gas is changed from 3.6 L to 15.5 L, the temperature will change from  ?? oC to 87°C

application of charles law

charle's law tells that 

T1/ V1 = T2 / V2, T must be in kelvin

it is given that  V1 = 3.6 L, V2 = 15.5 L, 
T2= </span><span>87°C= 360.15 K
</span>
so to find T1,  T1 =(T2 / V2) x V1

T1= (360.15 / 15.5) * 3.6= 83.64° K = - 190.15° C

A solution is prepared by dissolving 15.0 g of nh3 in 250.0 g of water. the density of the resulting 7)solution is 0.974 g/ml. t
GaryK [48]

0.0597 
 Mole fraction NH3 = moles NH3 / total moles in solution  
 moles NH3 = mass / molar mass  
 = 15.0 g / 17.034 g/mol  
 = 0.88059 moles    
 moles H2O = 250 g / 18.016 g/mol  
 = 13.8766 mol    
 total moles = 0.88059 + 13.8766  
 = 14.757 mol    
 fole fraction NH3 = 0.88059 / 14.757   
= 0.0597
