Answer:
D. The rate decreases as reactants are used up.
Explanation:
Initially, the rate increases until the reaction is at equilibrium. At equilibrium, the rate is constant.
As the reaction progresses, the rate decreases to zero when reactants are used up ( for irriversible reactions only )
(2C+2-H-X+N)/2
(2*6+2-12-0+0)/2

It's D because I know bcz I'm smart 8 times 8 is 60-nart
Answer:
The density of the nugget is 19.3g/cm³
It is gold because all samples of gold will have the same density value
You should buy it.
Explanation:
Given parameters:
Density of gold = 19.3g/cm³
Length on all sides = 5cm
Mass in kg = 2.413kg
Unknown:
Density = ?
Is it gold = ?
Should you buy it = ?
Solution:
To solve this problem, we need to find the density of the nugget first.
Density =
Mass = 2.413kg
We need to convert to g:
1kg = 1000g
2.413kg = 2413g
Volume = L³ = 5³ = 125cm³
Therefore;
Density = = 19.3g/cm³
The density of the nugget is 19.3g/cm³
It is gold because all samples of gold will have the same density value
You should buy it.
