Answer:
Explanation:
Thus, the ratio of the resistance force to the effort, called the actual mechanical advantage (AMA), is less than the IMA. The efficiency of any machine measures the degree to which friction and other factors reduce the actual work output of the machine from its theoretical maximum.
Use of thermostat is the most effective way to keep the reaction at a control temperature.
<h3>What is the most effective way to keep the reaction in control? </h3>
The reaction takes place in a thermostat is the most effective way to keep the reaction at a controlled and steady temperature because thermostat regulates the temperature of that solution which is placed in it. If the temperature goes higher then the extra heat is released from the system.
So we can conclude that use of thermostat is the most effective way to keep the reaction at a control temperature.

I think it is the first one, the second one, and the fifth one. Hopefully helps :)
Assuming the other part of the question is;
A solid mixture consists of 44.2g of KNO3 (potassium nitrate) and 7.8g of K2SO4 (potassium sulfate). The mixture is added to 130. g of water. (Assume KNO3 has a solubility of 14 g solute/ 100 g water)
Answer;
26 g
Solution;
-X g of KNO3/ 130 g water= 14 g of KNO3/ 100 g water
X= 18.2 g (this is the amount of solute that dissolves at 0 degrees C in 130 g water).
if you have 44.3g of KNO3 in 130 g of water at 0 degrees celsius and only 18.2 can dissolve then
44.2g - 18.2g = 26 g left undisolved which gives you the amount that would crystallize
Answer:
3,46 atm
Explanation:
Tenemos;
P1 =?
T1 = 100 + 273 = 373 K
V1 = 40 litros
P2 = 6 atmósferas
T2 = 50 + 273 = 323 K
V2 = 20 litros
Desde;
P1V1 / T1 = P2V2 / T2
P1V1T2 = P2V2T1
P1 = P2V2T1 / V1T2
P1 = 6 * 20 * 373/40 * 323
P1 = 44760/12920
P1 = 3,46 atm
