Answer:
By decreasing pressure.
Explanation:
In order to prevent balloons from popping while making sculptures, it is suggested to decrease the pressure of air in parent balloon. Decreasing the pressure of parent balloon will allow it to twist easily and make designs.
This strategy will work according to Boyle's Law which states that, "Pressure and Volume are inversely proportional to each other at constant temperature".
Mathematically,
P ∝ 1/V
Or,
P = k/V
Or,
PV = k
Hence, as the new designs made after twisting are of less volume, therefore it is good to decrease the pressure in advance otherwise the resulting less volume will increase the pressure of daughter small balloons and will explode them.
Explanation:
Dichloromethane is flammable - FALSE
Methanol is flammable. - TRUE
Concentrated sulfuric acid is corrosive. - TRUE
10% sodium carbonate solution must be used in the fume hood. - FALSE
Benzoyl chloride is a lachrymator. - TRUE
Answer:
86 mL
Explanation:
First find the moles of Pb (NO3)2
n=cv
where
c ( concentration)= 0.210 M
v ( volume in L) =0.05
n= 0.210 × 0.05
n= 0.0105
Using the mole ratio, we can find the moles of KCl by multiplying by 2
n (KCl) =0.0105 ×2
=0.021
v (KCl)= n/ c
= 0.021/ 0.244
=0.08606557377
=0.086 L
= 86 mL
