Aqueous strontium sulfide and aqueous copper(II) sulfate

ryzh [129]

Answer: The reaction does occur.

Explanation: For the reaction of aqueous strontium sulfide and aqueous copper(II) sulfate, the reaction follows:

$SrS(aq.)+CuSO_4(aq.)\rightarrow SrSO_4(aq.)+CuS(s)$

This reaction is a type of precipitation reaction.

The precipitate formed is CuS which is black in color.

Which of the following statements describe what a normative system is?

natta225 [31]

Explanation:

though the statements were not given let just give you a brief review of normative system.

A normative statement explains what should be base of the subject according to the belief through valued judgement that describes the fairness of the subject on public policy. Therefore, the unemployment rate should be lowered is a valued judgement based on the belief that it will bring economic welfare.

Normative systems, i.e., sets of norms, have two main. tions: a) to evaluate human actions, and b) to guide peop. The guidance and the evaluation based on a normativ. be good or bad.In social psychology three different normative behaviours have been identified: obedience, conformity and compliance.In the context of a normative system like law (or religion or morality), every statement of what one ought to do (or ought not to do) requires justification from a more general or basic statement. Such statements lead upward through the normative hierarchy until one reaches a foundational normative premise.

Answer:

1. 2Fe + 3CuSO₄ → Fe₂(SO₄)₃ + 3Cu.

2. Pb(NO₃)₂+ 2Kl → PbI₂ + 2KNO₃.

3. Mg + 2HCl → MgCl₂ + H₂.

4. H₂O → H₂ + 1/2O₂.

5. 2Mg + O₂ → 2MgO.

<h3 /><h2>explanation: 1. Combine iron and copper (II) sulfate solution. (Hint: Iron will form the iron (III) ion)</h2>

2Fe + 3CuSO₄ → Fe₂(SO₄)₃ + 3Cu.

It is a redox reaction including replacing Cu with Fe and changing their oxidation states.

That Fe replaces Cu and resulting in ferric sulfate.

2. Combine lead (II) nitrate and potassium iodide solutions.

Pb(NO₃)₂+ 2Kl → PbI₂ + 2KNO₃.

It is a double replacement reaction that lead nitrate reacts with potassium iodide resulting in lead iodide and potassium nitrate.

3. Combine magnesium metal and hydrochloric acid solution.

Mg + 2HCl → MgCl₂ + H₂.

It is a dissolution reaction that HCl dissolve Mg and resulting in Magnesium chloride and hydrogen gas is evolved.

4. Electrolysis (splitting) of water.

H₂O → H₂ + 1/2O₂.

Water electrolysis resulting in splitting of water to produce hydrogen and water.

5. Burning magnesium.

2Mg + O₂ → 2MgO.

It is a combustion reaction that Mg is burned with oxygen to produce magnesium oxide.

A canister of acetylene has a volume of 42 L. The temperature of the acetylene is 305 K and the pressure is 780 torr. Determine

stellarik [79]

First, we need to assume acetylene to adapt an ideal gas behavior. So, we can use the Ideal Gas Law:

PV = nRT

Given:

V = 42 L
T = 305 K
P = 780 torr = 1.026 atm
R = gas constant, 0.0821 L atm/ mol K
n = amount of gas in the canister

1.026 atm * 42 L = n * 0.0821 L atm/mol K * 305 K

n = 1.72 moles of gas
