A chemical reaction occurs when 2 white solids are stirred together they turn into a slushy white solid and the glass jar feels
Anestetic [448]

Answer:

Absorbed, endothermic

Explanation:

Based on the heat of reaction, chemical reactions may be classified as endothermic or exothermic.

In an endothermic reaction, heat is absorbed from the surrounding. As heat is absorbed from the surrounding, the reaction vessel feels cool when touched.

On the other hand, in an exothermic reaction, heat is given out by the system to the surrounding and the reaction vessel feels hot when touched.

Hence the reaction is endothermic and energy is absorbed during the reaction.

An object weighting 9.6 grams is placed in a graduated cylinder displacing the volume from 10.0mL to 13.2 mL
grigory [225]

The volume of object is 3.2 ml

<h3>Explanation:</h3>

Given:

Mass of the object = M = 9.6 g

Initial volume of liquid: V_1 = 10.0\ ml

Final volume of liquid after displacement: V_2 = 13.2\ ml

Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.

V = V_2-V_1 = 13.2 -1 0.0 = 3.2\ ml

V = 3.2 ml

Which would usually influence a reaction rate more? OH os O H&amp;S O Neither H nors
bagirrra123 [75]

Answer:

As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate. Hence the reaction rate of virtually all reactions increases with increasing temperature
