Answer:
CH4(g) + Cl2(g) = CCl4(g) + HCl(g)
Explanation:
Carbon tetrachloride is in the form of a colorless gas. It is not flammable and is not soluble in water (poor solubility). It is a compound used as a fire extinguisher and in the manufacture of refrigerants, but is currently discontinued for its toxicity. Exposure causes damage to the liver, kidneys and central nervous system. These effects can happen by breathing it or through skin contact. In the reaction the states of matter of each of the reagents and products are observed
Answer:
65.8mL of water and 184.2mL of the 95% EtOH stock solution must be added.
Explanation:
To solve this question we need to find hoy many times the 95% EtOH must be diluted to obtain a 70% EtOH solution. That is:
95% / 70% = 1.357 times the solution must be diluted.
If we want to make 250mL of the diluted solution, the amount of 95% that must be added is:
250mL / 1.357 times =
184.2mL of the 95% solution must be added
And of water:
250mL - 184.2mL = 65.8mL of water
Answer:
to balance a chemical equation the amount of reactants must be equal to the amount of products, an easy way to balance it is write out how many you have on both sides
Explanation:
if you're dealing with molecular equations you would do it like this:
eg. A double displacement reaction between magnesium hydroxide and hydrochloric acid
Mg(OH)2 (aq) + HCl (aq) = MgCl2 (aq) + H2O (l)
Mg-1. Mg-1
O-2. O-1 *2
H-2. H-2
Cl-1 *2 Cl-2
Balanced eq: Mg(OH)2 (aq) + 2HCl (aq) = MgCl2 (aq) + 2H2O (l)
if you're dealing with ionic equations , you would deal with charges and you would need to cancel out spectator ions, like this:
Mg^2+(aq) + 2OH^-(aq) + 2H^+ (aq) + 2Cl^- (aq) = Mg ^2+(aq)+ 2Cl^- (aq) + H20 (l)
the spectator ions are the ones that are the same on both sides which would be the Mg^2+ and the 2Cl^- so when writing the net ionic equation, it would just be:
2OH^-(aq) + 2H^+ (aq) = + H20 (l)
Answer:
MgCI2+ ___ AgNO3-->___Mg(NO3)2
i think u put 2 before NO3
