Veronica observes how the force of friction causes an object to slow down. She writes the following observation: When an object

moves across a smooth surface, there is less friction created than when an object moves across a rough surface. When the object stops moving, friction is created. Which statement corrects the error(s) in Veronica's observations?
It is not smooth or rough surfaces that affects friction. It is the size of the push.
When an object moves across a rough surface, there is no friction.
When an object moves across a smooth surface, the friction increases.
When an object stops moving, there is no friction.

It is not smooth or rough surfaces that affects friction. It is the size of the push.

A solution of copper sulfate (CuSO4) produced by bioleaching has a concentration of 0.319 g/dm3 Relative atomic masses (Ar): Cu
Tanya [424]

moles Cu produced : 0.002

<h3>Further explanation</h3>

Concentration of copper sulfate (CuSO₄) : 0.319 g/dm³

MW CuSO₄ :

\tt =63.5+32+4\times 16=159.5~g/mol

mol CuSO₄ /dm³ :

\tt \dfrac{0.319}{159.5}=0.002

CuSO₄⇒Cu²⁺ + SO₄²⁻

mol Cu : mol CuSO₄ = 1 : 1 , so mol Cu²⁺=0.002

Guillaume Amontons first took a stab at measuring absolute zero in 1702. What would be the most reasonable way it would have bee
Tema [17]

The most reasonable way to measure absolute zero would have been to extrapolate the ideal gas law.

<h3>What is Absolute zero?</h3>

This is referred to the temperature at which a thermodynamic system has the lowest form of energy.

Guillaume Amontons used gas equation to prove that absence of heat was theoretically possible which would have involved only extrapolating the ideal gas law.

abruzzese [7]

Answer:

Collecting data  

Step-by-step explanation:

During the observation phase of the scientific method, scientists are collecting data.

They can't create graphs or perform calculations, because they are still collecting data, nor can they report results to a colleague, because they have none to report.
