Answer:
Neon Ne has 10 electrons and Na+ also have 10 electrons
Explanation:
Answer:
The answer to your question is given below
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
Zn + 2HCl —> ZnCl2 + H2
Thus, we can write out the atoms present in both the reactant and the product by doing a simple head count. The atoms present are listed below:
Element >>> Reactant >>> Product
Zn >>>>>>>> 1 >>>>>>>>>> 1
H >>>>>>>>> 2 >>>>>>>>> 2
Cl >>>>>>>>> 2 >>>>>>>>> 2
Answer:
2000 mL
Explanation:
We have the following data:
Initial volume: V₁ = 1000 mL
Initial temperature: T₁ = -86°C + 273 = 187 K
Final temperature: T₂= 101°C + 273 = 374 K
According to Charles' law, as the temperature of a gas is increased at constant pressure, the volume is increased. That is expressed mathematically as:
V₁/T₁ = V₂/T₂
Thus, we calculate the final volume V₂ as follows:
V₂ = V₁/T₁ x T₂ = (1000 mL)/187 K x 374 K = 2000 mL
Therefore, the final volume is 2000 mL.
How do you find density?
Well, first D=m/v
D=density
M=mass
V=Volume
Volume of cube: 3*3*3=9cm cubed
Mass of cube: 25g
D=25g/9cm cubed
<span>2.8 g/cm cubed is the answer.
Hope this helps!</span>
