<h3><u>Answer;</u></h3>

Open

An electric circuit can have no current when a switch is <u>open</u>.

<h3><u>Explanation;</u></h3>
  • <em><u>An electric circuit is a path in which electrons from a voltage or current source flow. </u></em>
  • Electric switches are used to connect and break the flow of connectivity or flow of electrons in a circuit. A switch makes it easy to open or close an electrical circuit, turning the flow of electricity on or off.
  • <em><u>When a switch is closed the circuit is closed and thus the flow of current is on while when the switch is open, the circuit is open, and therefore there will be no flow of current in the circuit.</u></em>

What phenomenon in nature do scientists use to define the length of a meter? Why is this a better definition than “the length of
sergey [27]

Answer:

The natural phenomenon used to describe the length of a meter is the speed of light. The length of a meter is the length a light path travels in 1/(299792458) seconds through a vacuum.

The definition is better due to the uncertainty involved in the use of the length of a standard meter stick because the length of the meter stick could change due to atmospheric conditions from place to place

Predict the order of elution if you were to attempt to separate using column chromatography on silica gel and with a gradient el
Minchanka [31]

Answer:

Follows this order: B=> A => C.

Explanation:

NB: kindly check the attachment for the diagram of compounds A, B and C.

Elution is a very important concept in chromatography separation techniques. It deals with the use of eluent in the removal of an adsobate from an adsorbent. The principle behind Elution is just about how polar the solvent is.

So, in this question Compound B will go with the Elution first because of its polarity. Compound B has lesser polarity as compared to Compounds A and B.

Compound A will then elutes second because of its polarity too as resonance increases its polarity.

Last, compound C elutes because it has the highest polarity which is caused by electronegative atoms.

MrMuchimi

Answer:

2. Co(NO3)2 + H2

Explanation:

Hello,

In this case, we are evidencing a simple displacement reaction wherein the cobalt is able displace the hydrogen to produce cobalt (II) nitrate and gaseous hydrogen as a result of cobalt's higher activity:

2 HNO_3 + Co\rightarrow Co(NO_3)_2+H_2

Therefore, answer is 2. Co(NO3)2 + H2.

Best regards.
