Answer:
increases the frequency of particle collisions
Explanation:
One factor upon which the rate of reaction depends is the surface area of reactants.
According to the collision theory, reactions occur when reactant particles having the required (activation) energy collide with each other, this collision is inelastic. However, collision of particles having energies less than the activation energy results in elastic collisions and no chemical reaction.
The more the exposed surface area of reactants, the greater the number of particles that come into contact with each other and the more the chances of frequent effective collisions that lead to reaction.
Thus, powdered zinc reacts faster with hydrochloric acid than zinc strips
Answer : Option 1) The true statement is each carbon-oxygen bond is somewhere between a single and double bond and the actual structure of format is an average of the two resonance forms.
Explanation : The actual structure of formate is found to be a resonance hybrid of the two resonating forms. The actual structure for formate do not switches back and forth between two resonance forms.
The O atom in the formate molecule with one bond and three lone pairs, in the resonance form left with reference to the attached image, gets changed into O atom with two bonds and two lone pairs.
Again, the O atom with two bonds and two lone pairs on the resonance form left, changed into O atom with one bond and three lone pairs. It concludes that each carbon-oxygen bond is neither a single bond nor a double bond; each carbon-oxygen bond is somewhere between a single and double bond.
Also, it is seen that each oxygen atom does not have neither a double bond nor a single bond 50% of the time.
When gases dissolve in gases or when liquids and gases dissolve in liquids, particles movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.
Explanation:
When gases dissolve in gases or when liquids and gases dissolve in liquids, particle movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.
Solid particles do not dissolve easily like liquids and gases dissolve. Solid particles when dissolved in solid the particles moves very little. After getting heated and becomes molten then they get mixed.
But in the liquids and gases atoms moves and the particles get eventually spread and also get mixed after cooled.
The graph of the plot of acceleration against force is a straight line graph. Option B
<h3>What is the relationship between force and acceleration?</h3>
From the Newton's second law of motion we can derive that; F = ma
F= mass
a = acceleration.
This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.
As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B
