The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.

Answer:

False.

Explanation:

Rate of reaction  also depends on the number of collision that is being happening in reacting molecules. So concentration of the reactants is also important to decide the rate of reaction.

The rate of reaction is dependent on the concentration as well.

As the concentration of reactants decreases with time number of collisions also decreases .

Answer:

From your question you tried to compare reaction rate and time taken(reaction time)

The rate of a reaction is inversely proportional to the time taken(reaction time)

Explanation:

Reaction rate is said to be the decrease in concentration of the reactant or the increase in the concentration of the product per unit time. Reaction rate measures how fast the reactant is used up or how fast the product is formed.

For a given reaction like

Mg(s) + O2(g) → 2MgO(aq)

The reaction rate is derived by measuring how fast the concentration of Mg and O2 decreases or how fast the concentration of MgO increases. Mathematically reaction rate can be expressed as

Reaction rate = Δconcentration/ ΔTime

Reaction rate can be affected by various factors like temperature, reactant concentration and particle size of a solid reactant.   Increasing temperature, and increasing reactant concentration increases reaction rate. Decreasing particle size of the solid reactant also increase reaction rate.  The collision theory also shed more light on the rate of reaction. How fast the individual molecules of the reactant collide also affect the reaction rate.

The reaction time is the time taken for the reactant to form product. The reaction time is the time taken for the reaction to start and stop. The longer the reaction time, the slower the reaction rate. Fast reaction have short reaction time.

The rate of a reaction is inversely proportional to the time taken(reaction time)

PLEASE PLEASE PLEASE​ ANSWER HAVE MERCY 35 POINTS
Arada [10]
You should give answers since some people will just try and find any answer, which happened to me. So like if you have answers for the question just put them like A B C D kinda like true or false for others to know what they got instead of giving them more work, and then they just give you random answers.

Explain mitosis and meiosis in your own words.
LuckyWell [14K]
I always remembered the differences by Mitosis sounds like My Toes Is. Which means its body cells reproducing. 
And Meiosis is My overies. Which is sex cells reproducing. 

Mitosis - The body cell's nucleus makes a copy of its chromosomes. The Chromotids are then pulled to the poles of the cell and split in half, the cell then divides in half into two new cells. Each cell has one pair of chromosomes each.

Meiosis - The sex cells nucleus makes a copy of each chromosome same as before. But then the similar chromosomes group up and swap parts with each other. Making completely new chromosomes. They then split in half again, making two new cells with two different pairs of chromosomes. Which then split apart Once more creating 4 new cells (From the original one) Each with completely random chromosomes.

Why would the volume of one object calculated using “Measurement and Calculation” differ from the volume of the same object calc
Mars2501 [29]

Answer:

Measuring the Volume of Solids

Rectangular prism - Multiply the measurement of the length times the width, then times the height.

Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
