Answer:
1859.4 g of ZnCrO₄ in 10.25 moles
Explanation:
First of all, we determine the molecular formula of the compound:
Zinc → Zn²⁺ (cation)
Chromate → CrO₄⁻² (anion)
Zinc chromate → ZnCrO₄
Molar mass for the compound is:
Molar mass of Zn + Molar mass of Cr + (Molar mass of O) . 4 = 181.41 g/mol
65.41 g/mol + 52 g/mol + 16 g/mol . 4 = 181.41 g/mol
Let's apply this conversion factor: 10.25 mol . 181.41 g/mol = 1859.4 g
Answer:
sun, air, water, wind and ocean current
Explanation:
As sun is the major source of energy on earth, the earth gets heated due to solar energy, this creates convection currents in the Air and Water, the heating of these areas create wind and ocean currents due to difference in temperature and pressure.
Answer:
The equilibrium concentration of HCl is 0.01707 M.
Explanation:
Equilibrium constant of the reaction = 
Moles of ammonium chloride = 0.573 mol
Concentration of ammonium chloride = 
Initial: 0.573 0 0
At eq'm: (0.573-x) x x
We are given:
![[NH_4Cl]_{eq}=(0.573-x)](https://tex.z-dn.net/?f=%5BNH_4Cl%5D_%7Beq%7D%3D%280.573-x%29)
![[HCl]_{eq}=x](https://tex.z-dn.net/?f=%5BHCl%5D_%7Beq%7D%3Dx)
![[NH_3]_{eq}=x](https://tex.z-dn.net/?f=%5BNH_3%5D_%7Beq%7D%3Dx)
Calculating for 'x'. we get:
The expression of 
for above reaction follows:
![K_c=\frac{[HCl][NH_3]}{[NH_4Cl]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BHCl%5D%5BNH_3%5D%7D%7B%5BNH_4Cl%5D%7D)
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.01707 M
The equilibrium concentration of HCl is 0.01707 M.
Answer:
Mass is your answer: Please give brainleist, im close to the next rank
Explanation:
Mass is a fundamental measure of the amount of matter in the object. Kilogram (symbol: kg) is the base unit of mass in the International System of Units.
Orbiting or revolving could fit the term
