The density of zinc is 7.16 g/ml.
Density can be calculated by the formula -
Density =
In the given question, the volume of given mass of mossy zinc can be found by finding change in volume of water.
Change in volume = new volume - original volume
Change in volume = 54.6 - 50.0
Performing subtraction to find the change in volume
Change in volume = 4.6 ml
Now, keeping the values in formula to find the density of given mass of mossy zinc.
Density =
Performing division to find the density of given mass of mossy zinc
Density = 7.16 g/ml
Hence, the density of mossy zinc is 7.16 g/ml.

Answer:
0.00288 L = 2.88 mL.
Explanation:
- To calculate the no. of moles of a gas, we can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant.
T is the temperature of the gas in K.
- If n is constant, and have two different values of (P, V and T):
<em>P₁V₁T₂ = P₂V₂T₁</em>
<em></em>
P₁ = 1.0 atm, V₁ = 1.5 L, T₁ = 37°C + 273 = 310 K.
P₂ = 500.0 atm, V₂ = ??? L, T₂ = 25°C + 273 = 298 K.
<em>∴ V₂ = P₁V₁T₂/P₂T₁</em> = (1.0 atm)(1.5 L)(298 K)/(500.0 atm)(310 L) = <em>0.00288 L = 2.88 mL.</em>
The name is 2-Chloro Propane
Because the chlorine is linked to the second carbon atom when it is spread out
Answer:
Explanation:
Evaporation is inhibited by high humidity. Low humidity is as result of hotter temperatures that is temperature when the cup of water is under the sun and vice versa for high humidity.
Relative humidity defined as the amount of water vapor in the surrounding air compared with the maximum possible. At its maximum which is termed saturation, relative humidity is 100% and evaporation is inhibited.
The amount of water vapor the air can hold depends on its temperature. Relative humidity rises at low temperatures for example in an air conditioned environment. As the air temperature declines, sometimes reaching the dew point relative humidity is 100%, and fog may result from the condensation of water droplets if they are small enough to stay in suspension.
Drying is more effective with hot air rather than cold air, because hot air can hold more water vapor. The capacity of air to hold water vapor is based on vapor pressure of water. The liquid and solid phases are continuously giving off vapor because some of the molecules have high enough speeds to enter the gas phase.
Therefore, a cup of water placed in the sun will have a reduced water level compared to that in an air conditioned room.
