Answer:

Explanation:

A substance that undergoes a physical change is still the same substance after the changes. Matter occurs in three familiar states; 1)solid 2)liquid 3)gas An example of a physical change is when a liquid water changes into water vapor (gas) and mixes with the air or from a solid to a liquid.

HELP ME PLZ!!! I really dont know this!!! What characteristic of metals makes them good electrical conductors? -They have mobile

Natasha2012 [34]

Answer:

To have a high electrical conductivity, a normal metal should have mobile valence electrons and a long electron mean free path.

Explanation:

A long mean free path means that the electron goes a long distance between scattering events.

Write balanced ionic equations and net ionic equations for the following reactions.

Kipish [7]

The ionic equation will be:
Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l)
And the net ionic:
2OH-(aq) + 2H+(aq) → 2H2O(l)
a Balanced equation would be:
Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l)
Now thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times

Based on the activity series provided, which reactants will form products? F > Cl > Br > I CuI2 Br2 Right arrow. Cl2 Al

AleksAgata [21]

The reactants based on the reactivity capable of forming the products are $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.

The reactivity series has been the arrangement of the elements based on their reactivity. The highly reactive element has been capable of replacing the less reactive element in the compound, and form the product.

In the following reactions, the new product has been formed by:

$\rm CuI_2\;and\;Br_2$

From the reactivity series, Br has been more reactive than I, and thereby replaces iodine in the compound for the formation of product.

$\rm Cl_2\;and\;AlF_3$

The compound has been formed with F. Cl has been less reactive than F, and will not be able to form the product.

$\rm Br_2\;and\;NaCl$

The compound has been formed with Cl. Br has been less reactive than Cl, thus will not displaces Cl for the formation of new product.

$\rm CuF_2\;and\;I_2$

The compound has been formed with F. I has been less reactive than F, and will not be able to form the product.

The reactants that will be able to form the products have been $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.
