Answer:
The answer is
<h2>15.86 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of glycerol = 20 g
density = 1.261 g/mL
The volume is
We have the final answer as
15.86 mL

When a physical change occurs, the arrangement of particles within the substance may change, but the atoms in the molecules remain bonded together.
<h2>Answer:</h2>
The three examples of convection are
- The stack effect
- Oceanic circulation
- Hot air balloon
<h2>Explanation:</h2>
The stack effect is also referred to as the chimney effect which is the movement of air inside and outside of buildings, flues or any other objects because of buoyancy principle. In oceanic circulation warm water around the equator circulates towards the poles and the cooler water at the poles moves towards the equator. In hot air balloon, a heater inside the balloon heats the air and so the air moves upward.
29.0 mL in liters:
29.0 / 1000 => 0.029 L
n = M x V
n = 0.290 x 0.029
n = 0.00841 moles of NaOH

Answer:
30%
Explanation:
The relative humidity is the water-vapor content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth, the relative humidity very rarely falls below 30 percent.
