Answer : The specific heat of the metal is, 
Explanation
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of water = 
= mass of metal = 95.0g
= mass of water = 50.0 g
= final temperature of mixture = 
= initial temperature of metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get
![(95.0g)\times c_1\times (48.5-100.0)^oC=-[(50.0g)\times 4.18J/g^oC\times (48.5-22.5)^oC]](https://tex.z-dn.net/?f=%2895.0g%29%5Ctimes%20c_1%5Ctimes%20%2848.5-100.0%29%5EoC%3D-%5B%2850.0g%29%5Ctimes%204.18J%2Fg%5EoC%5Ctimes%20%2848.5-22.5%29%5EoC%5D)
Therefore, the specific heat of the metal is,
A physical change because it is still water :)
hey there!:
2HgO (s) => 2Hg (l) + O2 (g)
2 moles of HgO decompose to form 2 moles of Hg and 1 mole of O2 according to the reaction mentioned in the question.
So 4.00 moles of HgO must give 4 moles of Hg and 2 moles of O2 theoretically.
603 g of Hg = 603 / 200.6 = 3 moles
Percent yield = ( actual yield / theoretical yield) * 100
= ( 3/4) * 100
= 75 %
Hope this helps!
Answer is:
18 electrons.
<span>The principal quantum number (n) is one
of four quantum numbers which are assigned to each electron in an atom to
describe that electron's state.
The azimuthal quantum number (l) is a quantum number for
an atomic orbital that determines its orbital angular
momentum and describes the shape of the orbital, l = 0....n-1.</span>
<span>For n = 3, l = 0, 1, 2.</span>
<span>l = 0, s orbital with 2 electron.</span>
<span>l = 1, p orbitals with 6 electrons.</span>
<span>l = 2, d orbitals with 10 electrons.</span>
<span>2 + 6 + 10 = 18 electrons.</span>
The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD
