Why does a layer of ice form on the surface of a pond during freezing weather?

Biology

Answer:

Colder than 4° Celsius (39° Fahrenheit), water begins expanding and becomes less dense as it gets colder. As a result, close to freezing, colder water floats to the top and the warmer water sinks to the bottom. ... Ice is less dense than water because of the way it forms a hexagonal crystalline structure.

Explanation:

Hope that helps!

Answer:

Water freezes from the top down—which allows ice to float—because of a strange quirk in how water's density behaves at falling temperatures. ... At 4 °C water is still in its liquid form. In lakes and rivers, this water will cool at the surface, grow denser, and descend.

Based on the concept of the global conveyor belt, what happens to ocean water as it moves from Antarctica to the equator?
marta [7]

What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.

<h3>Concept conveyor belt </h3>

The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.

As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.

Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is  It becomes less dense and rises to the surface.

Is DNA a like a single blueprint for the building of a house or like a book of blueprints
Travka [436]
I think it would be more like a book of blue prints because you have so much in your DNA like a book but one blue print just shows you one structure. <span />

Part C
IrinaVladis [17]

Answer:

                     (i) 1 moles of C

                     (ii) 4.5 moles of C

Explanation:

                   The Chemical equation is as follow,

                                             A + 2 B  →  C

This chemical equation can be translated as;

(i) 1 mole of A reacts with 2 moles of B

(ii) 1 mole of A produces 1 mole of C

(iii) 2 moles of B reacts with 1 mole of A

(iv) 2 moles of B produces 1 mole of C

(v) 1 mole of C is produced by 1 mole of A and 2 moles of B

Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method.

As,

                        2 moles of B produced  =  1 mole of C

So,

                    2 moles of B will produce  =  X moles of C

Solving for X,

                      X =  2 moles × 1 mole / 2 moles

                      X =  1 moles of C

Note:

         In above problem the given moles were the same as that present in balance equation so incase if the moles are different from that of the equation then the method shown above can be used to solve it.

Lets try it for 9 moles of B:

As,

                        2 moles of B produced  =  1 mole of C

So,

                    9 moles of B will produce  =  X moles of C

Solving for X,

                      X =  9 moles × 1 mole / 2 moles

                      X =  4.5 moles of C
