Which would have the lowest input force?

Chemistry
1 answer:
Afina-wow [57]3 years ago
5 0

Answer:

A long lever with the fulcrum as close as possible to the load

Explanation:

If F be the effort , W be the weight , L₁  be the distance of load from fulcrum and L₂ be the distance of effort from the fulcrum ,

Taking moment of force about the fulcrum , we have

W x L₁ =  F x L₂

F = W x ( L₁ /  L₂ )

F will be minimum when L₁ will be minimum .

Hence  fulcrum should be as close as possible to the load.

Two aircraft rivets, one of iron and the other of copper, are placed in a calorimeter that has an initial temperature of 10°c.
Dominik [7]

a) Copper is at a higher temperature, so the flow of heat will take place from copper to iron. Heat is a form of energy, which always flows from higher temperature to lower temperature.  

b) To determine the actual final temperature, the heat capacity of the calorimeter must be known. A calorimeter constant refers to a constant, which quantifies the heat capacity of a calorimeter. It may be determined by using a known amount of heat to the calorimeter and measuring the corresponding change in temperature of the calorimeter.

What reaction might we use to synthesize nickel sulfate, NiSO4?
guapka [62]

As I understand from your question, we should synthesize nickel sulfate first from nickel (II) oxide and sulfuric acid and second from nickel carbonate and sulfuric acid.

The chemical reactions will look like this:

NiO (s) + H₂SO₄ (aq) → NiSO₄ (aq) + H₂O (l)

NiCO₃ (aq)* + H₂SO₄ → NiSO₄ (aq) + H₂CO₃ (aq)

but carbonic acid will decompose to carbon dioxide and water

H₂CO₃ (aq) → CO₂ (g) + H₂O (l)

(*) NiCO₃ has a poor solubility in water, but enough to start the reaction.
