Answer:
160
Explanation:
p*v/t = constant
or
p1*v1/t1 = p2*v2/t2
pressure is not stated in question so we get rid of it on both sides
v1/t1 = v2/t2
we are finding temperature so we flip the entire equation
t1/v1 = t2/v2
200/5 = t2/4
4(200/5) = t2
=160

Answer:
This question is incomplete
Explanation:
This question is incomplete but generally it seem to test the knowledge of accuracy. Accuracy is the closeness of a measured value to the specific or actual value of the substance being measured. Hence, the smaller the entire scale that can contain all the substance being measured, the higher the possibility of accuracy to be achieved. For example, a pen of 10.4 cm in length can be better/accurately measured (length) with a 30 cm meter rule than a 1 m meter rule.
From the question, the 50 mL beaker will provide a "more accurate" measurement of the volume of the bromine than the 100 mL beaker if the 50 mL beaker can contain all the sample of bromine water provided.
Decomposition using water polymerization
Answer:
Explanation:
percent yield is ratio of actual yield or experimental yield divided by theoretical yield multiplied by 100 .
percent yield of 93.4 % means , the actual yield is 93.4 % what was expected from the reaction on the basis of given chemical reaction .
If in the experimental process , some sodium hydrogen carbonate is left unreacted due to absence of reactant HCl which is also required to obtain product , the percent yield will be increased if the required HCl is also provided .
Hence the percent yield will be increased if required HCl is made available .
