D. 18 x 10^23 is the total number of atoms in 1.0 mole of CO2
Q=mcT
125cal=(60.0g)(0.0920)(T-21)
[(125)/(60)(0.0920)]+21=T2
T2=43.6C
The density of gold is 19.3 g/cm³
Ag= silver
Au= gold.
density (Ag)=10.5 g/cm³.
density (Au)=19.3 g/cm³
We have to calculate the mass of 5 cm³ silver:
10.5 g---------------------1 cm³
x--------------------------- 5 cm³
x=(10.5 g * 5 cm³) / 1cm³ ≈52.5 g
And we have to calculate the mass of 5 g gold.
19.3 g------------------------1 cm³
x-------------------------------5 cm³
x=(19.3 g * 5 cm³) / 1cm³≈96.5 g
Then 5 cm³ silver are 52.5 g of mass, and 5 cm³ gold are 96.5 g of mass, therefore, gold would have a greater mass than silver.
answer:5 cm³ gold would have a greater mass than 5 cm³ silver.
No because the one valence electron it had is gone so it’s not stable hope this helps
Answer:
temperature and mechanism
Explanation:
Arrhenius equation gives us the idea about the factors affecting equilibrium constant.It is given as:
<h3>
</h3>
where k=equilibrium constant
A=pre-exponential factor
=Activation energy
T=temperature
R=Universal gas constant
<h3>It is clear that k depends only on temperature and activation energy.</h3>
Activation energy of a reaction is different for different mechanisms or pathways.Hence k depends on both temperature and mechanism.
