Answer:

Explanation:

The boiling point of oxygen is -182.96 degrees Celsius (under 1 standard atmosphere). This means at temperatures below that point, oxygen is a solid or a liquid, and at temperatures above that point, oxygen is a gas. So at -183 degrees Celsius, oxygen is a liquid.

(CH3)2-CH-CH2-O(CH3)3IUPAC NAME
bazaltina [42]

Answer:

1-(tert-butoxy)-2-methylpropane

Note: there is a mistake in formula, the correct formula is (CH₃)₂-CH-CH₂-O-C(CH₃)₃ not (CH₃)₂-CH-CH₂-O(CH₃)₃, because oxygen is a divalent compound.

Explanation:

<em>Structural formula is attached</em>

IUPAC naming rules

1. start numbering the chain from the functional group. In this compound we        start from oxygen side.

2. Here we can see that at position 1 there is an oxy group along with a tertiary carbon having three methyl groups. So we write it as 1-tert-butoxy. Which means that there is a methoxy group at position 1 along with a tertiary carbon.

3. At position 2 we can see that there is a methyl group attached to the main chain, so we write it as 2-methyl.

4. Now we count the total number of carbons in the main chain. As we can see that there are 3 carbons in the remaining or parent chain, so we write it as propane

5. So the IUPAC name of the compound will be 1-(tert-butoxy)-2-methylpropane

7. Given a 32.0 g sample of methane gas (CH), determine the pressure that would be exerted on a container with
pishuonlain [190]

Answer:

P = 58.52 atm

Explanation:

Given data:

Mass of sample = 32.0 g

Pressure of sample = ?

Volume of gas = 850 cm³

Temperature of gas = 30°C

Solution:

Number of moles of gas:

Number of moles = mass/molar mass

Number of moles = 32.0 g/ 16 g/mol

Number of moles = 2 mol

Pressure of gas:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

850 cm³ × 1L /1000 cm³ = 0.85 L

by putting values,

P× 0.85 L = 2 mol × 0.0821 atm.L/ mol.K  × 303 K

P = 49.75 atm.L/ 0.85 L

P = 58.52 atm

Ag(No3)+Na3(Po4)+Ag3(Po4)+Na(No3)
musickatia [10]

3AgNO₃ + Na₃PO₄ → Ag₃PO₄ + 3NaNO₃

Explanation:

                         AgNO₃+Na₃(PO₄) → Ag₃(PO₄) + NaNO₃

To balance this chemical equation, we can adopt a simple mathematical approach through which we can establish simple and solvable algebraic equations.

           aAgNO₃ + bNa₃PO₄ → cAg₃PO₄ + dNaNO₃

a, b, c and d are the coefficients needed to balance the equation.

Conserving Ag:    a = 3c

                     N:      a = d

                     O:       2a + 4b = 4c + 2d

                     Na:      3b = d

                      P:        b = c  

let a = 1; d = 1

    b = \frac{1}{3}

    c = \frac{1}{3}

                         

Multiplying through by 3:

  a = 3, b = 1, c = 1 and d = 3

                3AgNO₃ + Na₃PO₄ → Ag₃PO₄ + 3NaNO₃
