Answer:

V = 1.434 L

Explanation:

Given data:

Mass of argon = 4.24 g

Temperature = 58.2 °C

Pressure = 1528 torr

Volume = ?

Solution:

58.2 °C = 58.2 + 273 = 331.2 K

1528/760= 2.01 atm

<em>Number of moles:</em>

Number of moles = mass/molar mass

Number of moles = 4.24 g / 39.948 g/mol

Number of moles = 0.106 mol

<em>Volume:</em>

PV = nRT

V = nRT/P

V =  0.106 mol ×0.0821. atm. L. mol⁻¹. K⁻¹ × 331.2K/ 2.01 atm

V = 2.88 atm L/ 2.01 atm

V = 1.434 L

For each ionic compound formula, identify the main group to which X belongs: (a) CaX2;
RideAnS [48]

For each ionic compound formula, identify the main group to group 17  (VIIA).

Group17 (VIIA) is the primary group to which X belongs in each ionic combination with the formula CaX2. X is undoubtedly an electron acceptor. It is capable of taking an electron. We determine that X must be in the oxidation state -1 by looking at the chemical formula. The neutral ionic compound's total number of oxidation states is zero. Since calcium has an oxidation state of +2, we must identify the element that contains an anion with an oxidation state of -1. The halogens have a strong propensity to pick up an electron and create an anion. X belongs to group17 (VIIA) as a result.

Aqueous solutions of lead nitrate and potassium iodide are combined in a test tube. The best proof that a chemical reactions has
tankabanditka [31]

C) A yellow precipitate settles to the bottom.

Explanation:

Lead nitrate is reacting with potassium iodide to form lead iodide, which is a yellow precipitate, and potassium nitrate.

Pb(NO₃)₂ (aq) + KI (aq) → PbI₂ (s) + KNO₃ (aq)

where:

(aq) - aqueous

(s) - solid

A) The solution is yellow.

False, the solution is colorless while the PbI₂ precipitate is yellow.

B) Both reactants are aqueous solutions.

True, however this is not a proof that the chemical reaction occurred.

C) A yellow precipitate settles to the bottom.

True and this is a proof that the chemical reaction occurred because of the formation of PbI₂ yellow precipitate.

D) Lead and potassium are both metals and will replace each other.

True, but this is not a proof that the chemical reaction occurred.

Fe + O2 --&gt; FeO (unbalanced). How many mLs of O2 are needed to react with 18.0 g of Fe ? *​
worty [1.4K]

0.161 mols.

Balance the equation first

2Fe + O2 •••••> 2FeO

Find the molar masses of the compound

2(56) + 2(16) •••••> 2(56+16)

112g + 32g •••••> 144g

Fe reacting with O2

112g of Fe reacting with 32g of O2

18g of Fe reacting with x

x= 32×18/112

x= 5.143g

Amount= mass/ molar mass

Amount= 5.143g/32g

Amount= 0.161mls
