<u>X(N03)2</u>

Given: Consider a hypothetical atom x

molecular formula of calcium nitrate = Ca(NO3)2

formula of x chloride is xcl2

molecular formula for x nitrate = ?

  • we are first putting calcium with chloride
  • on checking calcium on the periodic table we observe it in group 2
  • so calcium has two plus charge
  • whereas chloride being a halogen it is observed in group 7
  • it forms ion with one negative charge which would become CaCl2
  • so if we have Ca(NO3)2 and see a Cl2
  • with our hypothetical atom x , if the formula of x with chloride as XCl2 then formula with the nitrate is going to be x
  • this will be similar to calcium because calcium is just like it when we look at calcium with chloride
  • hence when x goes with nitrate it is going to look just like the formula for calcium nitrate
  • this gives us the final answer to be <u>X(NO3)2</u>

10. At 573K, NO2(g) decomposes forming NO and O2. The decomposition reaction is second order in NO2 with a rate constant of 1.1
leva [86]

Answer:

48.67 seconds

Explanation:

From;

1/[A] = kt + 1/[A]o

[A] = concentration at time t

t= time taken

k= rate constant

[A]o = initial concentration

Since [A] =[A]o - 0.75[A]o

[A] = 0.056 M - 0.042 M

[A] = 0.014 M

1/0.014 = (1.1t) + 1/0.056

71.4 - 17.86 = 1.1t

53.54 = 1.1t

t= 53.54/1.1

t= 48.67 seconds

Hence,it takes 48.67 seconds to decompose.

77julia77 [94]

Explanation: cell in the body is enclosed by a cell (Plasma) membrane. The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. ... All materials within a cell must have access to the cell membrane (the cell's boundary) for the needed exchange

Enter your answer in the provided box.
Lina20 [59]

Answer:

5.06atm

Explanation:

Using the combined gas law equation;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (Litres)

V2 = final volume (Litres)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

P1 = 1.34 atm

P2 = ?

V1 = 5.48 L

V2 = 1.32 L

T1 = 61 °C = 61 + 273 = 334K

T2 = 31 °C = 31 + 273 = 304K

Using P1V1/T1 = P2V2/T2

1.34 × 5.48/334 = P2 × 1.32/304

7.34/334 = 1.32P2/304

Cross multiply

334 × 1.32P2 = 304 × 7.34

440.88P2 = 2231.36

P2 = 2231.36/440.88

P2 = 5.06

The final pressure is 5.06atm
