Answer:
For dispensing, weigh it out.
Yes, a different solvent such as ethanol could be used.
Explanation:
Besides using various methods for melting the <em>tert</em>-butanol in order to pour it out and measure a given volume, the <em>tert</em>-butanol could be weighed out in a beaker using a scale. Depending on the temperature of the laboratory, the <em>tert</em>-butanol could be a solid or a liquid/solid mixture.
In general, a different solvent such as ethanol could be used in place of <em>tert</em>-butanol as long as the solvent is a low molecular weight alcohol.
This is a type of metathesis reaction, also referred to as double-displacement reactions. In this reaction, the solvent and electrolyte is water, and they are driven by the formation of the non-electrolytic product. Therefore, the driving force behind the neutralization reaction between HCl and NaOH is the formation of sodium chloride, NaCl.
SThe missing coefficient for the skeleton equation below is as follows
skeleton equation
Cr(s) + Fe(No3)2(aq) ------> Fe (s) + Cr(NO3)3 (aq)
the missing coefficient are is as follows
2 Cr(s) + 3 Fe(NO3)2 ---> 3 Fe (s) + 2 Cr(NO3)3
This is obtained by making sure all the molecules are balanced in both sides
11.2L/22.4L (STP value) x 1 mol of CH4 x 16.04 g of CH4 = 8.2 g
NH4I (aq) + KOH (aq) in chemical equation gives
NH4I (aq) + KOH (aq) = KI (aq) + H2O(l) + NH3 (l)
Ki is in aqueous state H2o is in liquid state while NH3 is in liquid state
from the equation above 1 mole of NH4I (aq) react with 1 mole of KOH(aq) to form 1mole of KI(aq) , 1mole of H2O(l) and 1 Mole of NH3(l)
