Svetach [21]3 years ago
4 0

Answer:

Cs > Iron > Aluminum > Carbon > Neon

Explanation:

The most metallic from the given choices is Cesium and the least metallic is Neon.

Neon is noble gas and not a solid.

Metallic character of elements decreases across the period and increases with increasing electronegativity.

The most leftward element is Cesium and will be the most metallic. Neon has the least metallic character since it is a noble gas.

    Cesium > Iron > Aluminum > Carbon > Neon

poizon [28]

Answer:

H2(g)+I2(s)→2HI(s)

Explanation:

Hello there!

In this case, according to the given information and unbalanced chemical reaction, we infer it must be balanced in agreement with the law of conservation of mass because the reactants side has two hydrogen and iodine atoms whereas the products side has just one. In such a way, by placing a 2 on HI, we obtain the following balanced reaction:

H2(g)+I2(s)→2HI(s)

Regards!

How can you determine an object mechanical energy
Dafna1 [17]
Objects have mechanical energyif they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving car possesses mechanical energydue to its motion (kineticenergy).
