Hey!!
here is your answer >>>
In order to find out which metal gains heat faster, we will have to find out their specific heat!. Specific heat is the heat required to raise the temperature of the unit substance, The specific heat of gold and brass are 0.126 for gold and 0.380 for brass!. The specific heat of gold is less than brass!. So, gold will gain heat faster!.
Hope my answer helps!
Acc. to Law of Conservation of Mass
Mass of reactants=Mass of Products
Let mass of Oxygen be x.
So,
50.6+x=452
x=452-50.6
=401.4 g
<span>570 torr.
The ideal gas law is
PV = nRT
where
P = pressure
V = volume
n = number of moles of gas particles
R = Ideal gas constant
T = absolute temperature
Since the value n, R, and T remain constant for this problem, that indicates that if the volume is doubled, the pressure will be halved. So the new pressure will be 1.50 atm / 2 = 0.750 atm. Now we just need to convert that from atm to torr. 1 atm is equal to 760 torr, so 0.750 atm * 760 torr/atm = 570 torr.</span>
Answer:
56.0 g
Explanation:
Calculation of the moles of 
as:-
Mass = 85.0 g
Molar mass of = 162.2 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction:-
1 mole of on reaction forms 1 mole of 
Also,
0.52404 mole of on reaction forms 0.52404 mole of
Moles of = 0.52404 moles
Molar mass of = 106.867 g/mol
Mass = Moles*Molar mass = 
= 56.0 g
