In terms of particle movement and energy what occurs when a solid is heated to its melting point

Lelechka [254]

The particles are given more energy and start to vibrate faster. In certain temps the particles vibrate so much that their ordered structure breaks down to the point the solid melts into liquid

Can I get some help please I’m lost :(

Molodets [167]

Answer:

C) 11 g

Explanation:

first look to graph , you have x and y

x is mass of Fe

and y is mass of product

if the reaction consumes 2 g of Fe , ( look to x axis , look to 2 )

and go up until the black line touch the line of number 2

and go left and you will see the point become in the middle between 10 and 12

** 12 (11) 10 ***

Good Luck

How many moles of nitrate are dissolved in water if 6.15 mole strontium nitrate dissolve?

pashok25 [27]

The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles

<u>Given data :</u>

Moles of strontium nitrate = 6.15 moles

<h3>Ionization of Strontium Nitrate </h3>

When strontium nitrate ( $Sr(NO_{3} )_{2}$ ) is placed in water it will dissociates into its ions because strontium nitrate is an ionic compound.

Next step : Represent the ionization of strontium nitrate

$Sr ( NO_{3} )_{2} (aq) --- > Sr^{2+} (aq) + 2NO_{3} ^{-} (aq)$

From the Stoichiometry of the chemical reaction

I mole of strontium nitrate = 2 moles of Nitrate ions

6.15 mole of strontium nitrate = 2 * 6.15

= 12.3 moles of Nitrate

Hence we can conclude that The number of moles of nitrate dissolved in water if 6.15 mole of strontium nitrate is : 12.3 moles.
