<span>There are many different kinds of clouds all around us. Clouds come in diverse shapes and colors. Some clouds are fluffy and others are wispy. Some clouds float high in the sky and others sit low on the ground. Some clouds warn of storms and other clouds tell of fair weather. Compare and contrast the characteristics of different types of clouds through vibrant photographs.</span>
Hydrochloric Acid (HCl) is a strong acid when it is present in the concentrated form but when it is dissolved in water () the atoms of this compound dissociates into its respective ions as shown below:
When we add HCl to any complex in its concentrated form the complex does not react at all but when its diluted to 6M and is kept for many hours, the complex reacts slowly. For eg:
As seen from the above reaction it can be seen the positive charge on the complex is reduced by 1 unit because one ion gets attached to the centre metal atom, therefore we can conclude that the charge on complex gets reduced by 1 unit when HCl reacts with the complex.
Hey!
I would say the answer is A. Plow the soil many times to lessen the chance of the topsoil being blown away.
Hope this helps !
Molar mass CHCl₃= 12.01 + 1.0079 + 35.45 x 3 = 119.3679 g/mol
119.3679 g ----------- 100%
106.35 g Cl ----------- ?%
Cl = 106.35 x 100 / 119.3679
Cl = 10635 / 119.3679
Cl = 89.09%
<span>A is the correct answer. Tying back long hair and loose clothing is important so they don’t dangle in flames or liquids that could dissolve or bleach them, for example. The other choices - consuming food and drink from lab wares, touching hot objects without gloves on and inhaling odors - are examples of very unsafe procedures. </span>
