1.) Group 1 2.) Group 2 3.) Group 13 4.) Group 14 This question doesn't make any sense to me :/ Can you please explain it?
1.) NaCl(s) 2.) NaCl(aq) 3.) H2O(s) 4.) H20(g) I honestly don't understand this question. Conductor of what?
1.) KI 2.)HCl 3.) MgS 4.) NO
1. 4 and 0 2. 3 and 1 3. 3 and 0 4. 2 and 2
1. X (Two dots at top)
2. X (Dots all around except on right, only has one instead of two)
3. X (One on the right)
4. X (Dots all around except on left, only has on instead of two)
Why does atomic number increase as atomic radius decreases? This is for chemistry class.
At 1 atm, how much energy is required to heat 83.0 g of H2O(s) at –12.0 °C to H2O(g) at 115.0 °C?
1.) If 16.45 mL of 0.135 M nitric acid neutralizes 26.0 mL of ammonium hydroxide, what is the molarity of the base?
HNO3(aq) + NH4OH(aq) --> NH4NO3(aq) + H2O(l)
I used stoichiometry...
i need ti know how many electrons aluminum have
a. HCl(aq) and HC2H3O2(aq)
b. H+(aq) + Cl-(aq) and HC2H3O2(aq)
c. HCl(aq) and H+(aq) + C2H3O2-(aq)
d. H+(aq) + Cl-(aq) and H+(aq) + C2H3O2-(aq)
When 9.12 g of HCl was dissolved in 190 g of water, the freezing point of the solution was -4.65oC. What is the value of the van't Hoff factor for HCl?
Here is what I did-
I know that...
The reaction between bleach and ammonia to yield chlorine gas has a deltaH= -422 kJ
What is the value of deltaE in kilojoules if the reaction is carried out at a constant pressure of 28.0 atom...
A foul smelling gas produced by the reaction of HCL and Na2S:
2HCl + Na2S --> 2NaCl + H2S
is collected in and a 1.00 L sample was found. How many moles were found in the sample...
i do not know how to work this out please help me
it is a true or false question
1. 5.00 g LiCl/ 95.0 g water
2. 100 g solution/ 5.00 g LiCl
3. 5.00 g LiCl/ 95.0 g solution
4. 95.0 g water/ 5.00 g LiCl
5. 95.0 g water/ 100 g solution
I have no idea, please...
Please explain how to do this! Thanks.
