Answer:

86618.5

Explanation:

The number 8.66185.10^4 is written in scientific notation

To write8.66185.10^4 in standard notation we must run the comma to the right (because the power is positive) 4 places (because the power of ten equals 4)

8.66185.10^4=  86618.5

How many mole of ZnCl2 will be produced from 55.0 g of Zn, assuming HCL is available in excess
Ilia_Sergeevich [38]

Answer:

0.84 mol

Explanation:

Given data:

Moles  of ZnCl₂ produced = ?

Mass of Zn = 55.0 g

Solution:

Chemical equation:

2HCl + Zn  →  ZnCl₂ + H₂

Number of moles of Zn:

Number of moles = mass / molar mass

Number of moles = 55.0 g/ 65.38 g/mol

Number of moles = 0.84 mol

Now we will compare the moles of Zn with ZnCl₂ from balance chemical equation.

                                      Zn          :             ZnCl₂

                                         1          :               1

                                      0.84       :           0.84

So from 55 g of Zn 0.84 moles of zinc chloride will be produced.

How would you prepare 100.0 ml of.400 m CaCl2 from a stock solution of 2.00 M CaCl2?
docker41 [41]
C₀=2 mol/l
c₁=0.400 mol/l
v₁=100.0 ml = 0.1 l

c₁v₁=c₀v₀

v₀=c₁v₁/c₀
v(H₂O)=v₁-v₀

v₀=0.1*0.400/2=0.02 l = 20 ml
v(H₂O)=100 - 20 = 80 ml

It is necessary to mix 20 ml of the feed solution and 80 ml of water.

For an ideal gas under constant volume, if the pressure is tripled, what happens to the Kelvin temperature?
EleoNora [17]

Answer:

Increase pressure 3X => increase Temperature 3X

Explanation:

Gay-Lussac Law => T ∝ P => T =kP => Empirical Relationship => T₁/P₁ = T₂/P₂  

=> T₂ = T₁P₂/P₁

Given P₂ = 3P₁ => T₂ = T₁(3P₁)/P₁ = 3T₁
