Answer:1)Once the wick is wet, hold the handle and whirl the psychrometer in the air. Whirling generates airflow around both the wet and dry bulbs. This action allows water in the saturated wick to evaporate, thereby reducing the temperature of the wet-bulb thermometer.
2)The rate of evaporation from the wet bandage on the bulb, and the temperature difference between the dry bulb and wet bulb, depends on the humidity of the air. The evaporation is reduced when the air contains more water vapor.
Explanation:
Answer:
water vapor
Explanation:
the the answer is water vapor
Answer:
Explanation:
(a) Balanced equation
Cu + 2AgNO₃ ⟶ Cu(NO₃)₂+ 2Ag
(b) Calculation
You want to convert atoms of Cu to atoms of Ag.
The atomic ratio is ratio is 2 atoms Ag:1 atom Cu
Calculating the molar mass of naphthalene (C10H8)
molar mass = 10 x (12.01) + 8(1.008)
= 120.1 + 8.064 = 128.164 g/mol
I think the correct order according to increasing acid strength would be the one in option B. The order is:
<span>HBrO < HBrO2 < HBrO3 < HBrO4
</span>
The more oxygen atoms means the easier the hydronium ions is removed in aqueous solution since the oxygen has a high electronegativity.
