It would be nice if someone HELPED. During an experiment, you observe that two charged balloons repel each other. When you bring

a charged plastic pipe in between the two charged balloons, both balloons are repelled from the pipe. What is the best conclusion statement about the balloons and pipe, based on the observations?
They are oppositely charged, which is why they repel each other.
They are similarly charged, which is why they repel each other.
The balloons transferred charge to the pipe, making the pipe repel the balloons.
They must be different colors, which is why they repel each other.

Allushta [10]

Answer:

2C_{10} H_{22(l)} + 31O2(g)--> 20CO_{2(g)} + 22H_{2}O_{(g)}

Explanation:

2C_{10} H_{22(g)} + 31O2(g)--> 20CO_{2(g)} + 22H_{2}O_{(g)}

From the question, one can work out which states of matter to assign to which species. The trick with organic equations of this nature is to try to balance everything but oxygen first. Make sure you balance oxygen last because it is the easiest to balance.

An atom with a high metallic character usually has a ____ electron affinity and a ____ atomic radius.
lianna [129]

Low electron affinity and large atomic radius

Metallic character decreases across a period (from left to right) and increases down a group.

Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.

Photo 1: Chemical Equation for Redox of Copper and Silver Nitrate. Note: Copper has a 2 oxidation number in the products.Silver
Mekhanik [1.2K]

The copper atom is oxidized while the silver is reduced.

<h3>What is a redox reaction?</h3>

A redox reaction is one that occurs between an oxidizing agent and a reducing agent. One specie is oxidized while the other specie is reduced in the reaction.

In this case, the oxidizing agent is the silver and the reducing agent is the copper atom. The copper atom is oxidized while the silver is reduced.

The complete equation is;

Cu(s) + 2AgNO3(aq) -----> Cu(NO3)2(aq) + Ag(s)

Ionically;

Cu(s) + 2Ag^+ -----> Cu^2+(aq) + Ag(s)
