Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

Reaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in concentration of the gas.

<h3><u>Answer;</u></h3>

The temperatures of the two substances equalize.

<h3><u>Explanation;</u></h3>

When two objects at different temperatures are placed in contact, heat flows from the warmer object to the cooler one until the temperature of both objects is the same.
<em><u>The amount of heat that flows from a warmer object is the same as the amount of heat that flows into a cooler object. Because the direction of heat flow is opposite for the two objects, the sign of the heat flow values must be opposite. </u></em>
<em><u>In line with the law of conservation of energy, the amount of heat lost by a warmer object equals the amount of heat gained by a cooler object. Therefore the amount of heat lost by carbon dioxide is equal to the amount of heat gained by water.</u></em>

Lady bird [3.3K]

Each kind of scientist is matched with an aspect of the hot spring he or she is most likely to study as follows:

<u>Geologist:</u> rocks around and under the hot spring.
<u>Ecologist:</u> relationships between organisms and the hot spring.
<u>Sociologist:</u> human behavior around the hot spring.
<u>Meteorologist:</u> atmosphere and weather around the hot spring.

<h3>What is a scientific observation?</h3>

A scientific observation can be defined as an active acquisition of knowledge (information) through one of the sense organs, while using scientific tools and instruments.

<h3>The types of scientific observation.</h3>

In Science, there are two main types of scientific observation and these include the following:

Qualitative observation

Quantitative observation

<h3>What is a hot spring?</h3>

A hot spring can be defined as a natural or an artificially-induced phenomena in which very hot groundwater flows out from the Earth's crust due to the heat present in the geosphere.

In this exercise, you're required to match each kind of scientist with an aspect of the hot spring he or she is most likely to study as follows:

<u>Geologist:</u> rocks around and under the hot spring.
<u>Ecologist:</u> relationships between organisms and the hot spring.
<u>Sociologist:</u> human behavior around the hot spring.
<u>Meteorologist:</u> atmosphere and weather around the hot spring.

Identify the neutralization reaction

KIM [24]

In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which an acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
