What indicators of a chemical reaction occurred in the following equation?

Chemistry
1 answer:
ch4aika [34]3 years ago
6 0

Answer:

1) evolution of gas

2) evolution of heat

Explanation:

In this reaction, glucose is broken down into its constituents; carbon dioxide and water. The question is to decipher indicators of a chemical reaction from the equation.

If we look at the equation carefully, we will notice that a gas was evolved (CO2). The evolution of a gas indicates that a chemical reaction must have taken place. Secondly, energy is given off as heat. This is another indication that a chemical reaction has taken place.

Under what conditions does the molar volume of a gas decrease
nydimaria [60]

Answer:

Gases are compressible, meaning that when put under high pressure, the particles are forced closer to one another. This decreases the amount of empty space and reduces the volume of the gas. Gas volume is also affected by temperature. When a gas is heated, its molecules move faster and the gas expands.

Water readily sticks to many other substances, a property called ______. Water readily sticks to many other substances, a proper
Ahat [919]

Answer:

Option (2)

Explanation:

Cohesion is usually defined as the contrasting property by which the water molecules are attached to one another, and adhesion is the property by which the molecular substances are linked to the molecules of other substances.

Since, the water molecules are able to form inter-molecular hydrogen bonding, so they are comprised of strong cohesive force.

And, as the water molecules are able to stick to the walls of the container, so they tend to show more of the properties for adhesion.

Thus, according to the given condition, water molecules are sticking to other substances and this is the property of adhesion.

Hence, the correct answer is option (2).

Because of its high reactivity which element is normally obtained by the electrolysis
katrin [286]

<span>Lithium has a property of high reactivity and to obtain lithium is through electrolysis of its fused salts. Because lithium is very reactive, it is not found free so electrolysis is use to split it apart to get it.  Moreover, Lithium is an alkali metal with single valence electron that is easily given up to form cation, which make it a good conductor of heat and electricity.</span>

How do the particles in s waves move
Darya [45]
In a surface wave, particles of the medium move up and down as well as back and forth in an overall circular motion. The particles don't actually move closer to shore as the waves pass through. In shallow water close to shore, waves start to drag on the bottom of the water.
