Answer: 2 PCl3 + 2 Cl2 > 2 PCl5

Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.

For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +

(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.

The chemical reaction will have a balance chemical equation.

Iron combines with 5 g of Copper (1) Nitrate to form 6.01 g of Iron (1) Nitrate and 0.4 g of copper

Ivanshal [37]

First, you would add the products: 0.4 + 6.01 = 6.41 g
Then, to get the mass of Iron required, you would do 6.41 - 5.0 = 1.41
This is because in the conservation of mass principle it states,
mass of reactants = mass of products.

Olive oil has a density of 0.92 g/mL. How much would 1 liter of olive oil weigh in grams?

svp [43]

Dimension analysis is to be used to solve this problem. First convert 1L to milliliters. That is equivalent to 1000 ml. Then by dimension analysis, multiply the volume ( 1000ml) to the density of oil (0.92 g/ml) resulting to the answer: 920 grams.

Write an equilibrium expression for each chemical equation involving one or more solid or liquid reactants or products. Part A:

madam [21]

Answer:

Part A: $Kc=\frac{C.D}{A}$

Part B: $Kc=\frac{C.D}{A}$

Part C: $Kc=\frac{C^{2} }{B}$

Part D: $Kc=\frac{C^{2} }{B}$

Explanation:

<em>Write an equilibrium expression for each chemical equation involving one or more solid or liquid reactants or products.</em>

The equilibrium constant (Kc) is equal to the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species (not liquids or solids).

Part A: HCHO₂(aq) + H₂O(l) ⇌ H₃O⁺(aq) + CHO₂⁻(aq)

Use A for [HCHO₂], B for [H₂O], C for [H₃O⁺], D for [CHO₂⁻].

$Kc=\frac{C.D}{A}$

PART B: CO₃²⁻(aq) + H₂O(l) ⇌ HCO₃⁻(aq) + OH⁻(aq)

Use A for [CO₃²⁻], B for [H₂O], C for [HCO₃⁻], D for [OH⁻].

$Kc=\frac{C.D}{A}$

PART C: 2 C(s) + O₂(g) ⇌ 2 CO(g)

Use A for [C], B for [O₂], C for [CO].

$Kc=\frac{C^{2} }{B}$

PART D: C(s) + CO₂(g) ⇌ 2 CO(g)

Use A for [C], B for [CO₂], C for [CO].

$Kc=\frac{C^{2} }{B}$

What happens to an atom of sulfur (S) if it loses an electron?

WITCHER [35]

Answer:

An atom becomes anion when it gains or loses electrons. The ions that are formed when an atom loses electrons are positively charged because they have more protons in the nucleus than electrons in the electron cloud.
