Answer:
Iron
Explanation:
Heat released by the metal sample will be equivalent to the heat absorbed by water.
But heat = mass × specific heat capacity × temperature change
Thus;
Heat released by the metal;
= 45.9 g × c ×(95.2 -24.5) , where c is the specific heat capacity of the metal
= 3245.13c joules
Heat absorbed by water;
= 120 g × 4.18 J/g°C × (24.5-21.6)
= 1454.64 joules
Therefore;
3245.13c joules = 1454.64 joules
c = 1454.64/3245.13
= 0.448 J/g°C
The specific heat capacity of the metal sample is 0.448 J/g°C. The metal use is most likely, Iron.
The coefficient that would need to be placed in front of the H2, to balance the equation would be 2. After doing this all of the atoms for their respective elements will be balanced.
<span>About a fifth of the air is made up of oxygen, and almost all the rest is nitrogen. But the origins of the relatively high nitrogen content of Earth’s air have been something of a mystery.</span>
Because metals are malleable, which means they are bendable but not easily breakable. Hope this helps!
Answer:
<h3>A Werewolf</h3>
___________
Poem with Compound Words
------------------------------------------
whenever there's a full moon,
I cannot overlook,
some alterations in my ways,
and changes in my look.
my werewolf hair grows everywhere,
my werewolf teeth get long,
my eyesight gets much keener and
I'm muscular and strong.
I get to roam around outside,
the moonlight makes me howl,
these otherworldly sound effects
mean I am on the prawl.
I see the moon is round and full,
I'm moonstruck by the sight,
I've made some telltale changes-so, you'd best stay in tonight.
