Answer:
Water is polar covalent while isoporopanol is covalent
Explanation:
Water contains polar covalent bonds. Water has a high dipole moment and thus dissolves ionic substances easily such as sodium chloride. Water is also a good electrolyte. Water is not volatile. Water molecules are held together by hydrogen bonds. Isopropanol is a covalent compound. It is non polar and suitable for dissolving non polar substances such as campohor. It is volatile but dissolves in water due the the -OH group present in the molecule.
Correct answers are D, A, A, B, A
<span>1) V1/T1=V2/T2 --> V2 = V1x(T2/T1) = 300cm³ x (333K/303K) = 330cm³ (assuming constant P) </span>
<span>2) V1/T1=V2/T2 -->V1=V2x(T1/T2) = 1.0Lx(300K/100K) = 3.0L </span>
<span>3) you have 2x as many moles of antacid ---> 2x as many moles of gas...V1/n1 = V2/n2 ---> V2 = V1 x (n2/n1).. double the moles, double the volume... so gas from 4 tablets > gas from 2 tablets. </span>
<span>4) P1/T1=P2/T2 ---> P2=P1x(T2/T1)..if T was left in °C, P2=100kPax(10°C/60°C) = 17kPa. T MUST be in absolute temperature. either K or R. never °F nor °C. units of P do not matter. </span>
<span>5).. constant T,n = boyles, constant P,n = charles, constant V,n = Gay-Lussac's</span>
Answer:
Explanation:
The balanced reaction of heating solid lead (II) sulfide with the solid lead (II) sulfate to produce liquid lead and sulfur dioxide gas is shown below:
In the balance reaction above, all the phases are indicated. This reaction is used for the production of lead metal.
Answer = C. As the temperature increases, the speed of gas molecules increases.
As the temperature increases, the gas molecules gain kinetic energy, therefore their speed increases.
