Cation means a positively charged ion. Anion is a negative one
Answer:
1.34L
Explanation:
1 torr = 0.00132atm
P2= 2584torr = 3.41atm
T2= 37°C = 273+37 = 310K
Using combined gas law
P1V1/T1 = P2V2/T2
(1.1×4.0)/298 = (3.41 × V2)/310
V2= (1.1×4×310)/(298×3.41)
V2= 1.34L
Answer:
Biodiversity will decrease.
Explanation:
The likely result of clearing the fields for building homes is that biodiversity will decrease.
Biodiversity is the variation in life forms within a particular area.
- The balance of the ecosystem is easily tripped by the influence of human activities.
- Some habitats are easily destroyed when new fields are cleared.
- Habitat loss is huge problem, in the ecosystem as a result of human activities.
Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution (
) and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.

This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.

As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution

Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
<u>Answer:</u> The value of
for the given chemical equation is 0.0457.
<u>Explanation:</u>
Given values:
Initial moles of
= 0.700 moles
Volume of conatiner = 3.50 L
The given chemical equation follows:

I: 0.700
C: -2x +2x x
E: 0.700-2x 2x x
Equilibrium moles of
= x = 0.180 moles
Equilibrium moles of
= 2x = 
Equilibrium moles of
= 0.700 - 2x = 
Molarity is calculated by using the equation:

So,
![[SO_3]_{eq}=\frac{0.340}{3.50}=0.0971M](https://tex.z-dn.net/?f=%5BSO_3%5D_%7Beq%7D%3D%5Cfrac%7B0.340%7D%7B3.50%7D%3D0.0971M)
![[SO_2]_{eq}=\frac{0.360}{3.50}=0.103M](https://tex.z-dn.net/?f=%5BSO_2%5D_%7Beq%7D%3D%5Cfrac%7B0.360%7D%7B3.50%7D%3D0.103M)
![[O_2]_{eq}=\frac{0.180}{3.50}=0.0514M](https://tex.z-dn.net/?f=%5BO_2%5D_%7Beq%7D%3D%5Cfrac%7B0.180%7D%7B3.50%7D%3D0.0514M)
The expression of
for above equation follows:
![K_c=\frac{[SO_2]^2[O_2]}{[SO_3]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BSO_2%5D%5E2%5BO_2%5D%7D%7B%5BSO_3%5D%5E2%7D)
Plugging values in above expression:

Hence, the value of
for the given chemical equation is 0.0457.
