The shape that is formed by the free surface, which is called a hyperboloid, or "Gabriel's Horn". The core of a vortex in air is sometimes visible because a plume of water vapor that is caused by condensation in the low pressure and low temperature of the core. An example of this is the sprout of a tornado. Vortices form in stirred fluids and could be observed in phenomena such as smoke rings, whirlpools in the wake of a boat, or the winds surrounding a tornado or dust devil.
Explanation:
For Mg, (1.2 g Mg/24 g Mg) = 0.05 mol Mg.
For Cl, (3.55 g Cl/35.5 g Cl) = 0.1 mol Cl
So the ratio now is
Mg:Cl = 0.05 : 0.1 = 1:2
I got the 1:2 ratio by dividing both by the smallest number, which is 0.05 mol. Therefore, the empirical for formula of the substance is
Answer:
C
Explanation:
Because 2 x n square gives the total energy level been absorbed = 2 x16
=32
Answer:
3.37 m
Explanation:
<u>Number of moles of solute present in 1 kg of solvent is termed as molality</u>
It is represented by 'm'.
Thus,
Given that:
The mass of LiCl = 15.0 g
Molar mass of LiCl = 42.394 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of the solvent = 105 g
Also, 1 g = 0.001 g
So,
Mass of water (solvent) = 0.105 kg
Molality is:
<u>Molality = 3.37 m</u>
<u>Answer:</u>
<em>Latest take an example to understand how </em><em>balancing of chemical reaction</em><em> is done that is assuming the reaction between iron as well as </em><em>oxygen which reacts to form rust.</em>
<u>Explanation:</u>
For this we would simply right the reactant and product that is expected. Then we would see the number of molecules of each element present on either side.
If in the reaction the element’s molecules are the same on both sides then the reaction would be correct and if not then we have to apply trial and error method to balance the equation such that the number of molecules of each element is equal on both sides of the reaction.
