The answer is A cause the water breaks down the rocks into small pieces which are called sediments. These things later on turn into rocks with pressure and heat
Answer:
Conductors allow a flow of current or a charge of flow
I hope this helped! Please rate it the brainlist if possible, thanks
Answer:
1.56 M
Explanation:
This is a dilution process and so a dilution formula is suitably used as follows C1V1 = C2V2 where
C1 = concentration of the stock solution
V1 = volume of the stock solution
C2 = concentration of the resulting (dilute) solution and
V2 = the volume of the resulting (dilute) solution
C1V1 = C2V2 (Making C2 subject of the formula)
C2 = C1V1/V2
Given: C1 = 5.736 M; V1 = 3 Ml; V2 = (3+8) 11 Ml
C2 = 5.736 x 3 / 11
C2 = 1.56 M
Copper is sought because it is a very useful metal used for conducting heat and electricity, its made of one pure element called copper (not surprisingly) and is slightly uncommon. Making its demand higher.
Answer is "A".
Explanation;
Physical changes mean an arrangement of particles of a given substance without producing new substance but changes in physical form of the substance.
<em>Example :</em> vaporization of water ( water goes its gaseous phase from liquid form).
Chemical changes mean an arrangement of particles while forming new substance.
<em>Example : </em>heating of CaCO₃. (In this process CaO and CO₂ are formed).
In this problem, the volume of water has decreased. Hence, it can be said that this is an example of physical changes due to not forming of new substance.
