Answer:

This is where google becomes your best friend but I got you

Explanation:

1.  A theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.

2. Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.

3. The speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

4. There are four main factors that can affect the reaction rate of a chemical reaction:

Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...

Physical state of the reactants and surface area. ...

Temperature. ...

Presence of a catalyst.

Answer:

1. a theory that says a chemical reaction takes place when particles of the reactants collide with sufficient energy to initiate the reaction

2. Increasing the concentration of the reactants, the faster the particles will collide so the reaction rate will be faster

3. a measure of how fast a reaction takes place

4. Temperature, presence of a catalyst, reactant concentration, surface area

Answer:

Newton's third law is: For every action, there is an equal and opposite reaction.

Explanation:

FA = −FB. if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction

Cuticles are protective lining in the epidermal layer of plants. Cuticles helps to reduce water loss and protect the plants from environmental stresses.

Cuticle is an organism's external layer or area that makes touch with the environment. The epidermis secretes the dead, noncellular cuticle in many invertebrate species. In humans, the cuticle is the epidermis, and this layer may include colours and chitin, similar to arthropods.

The cuticle is a protective coating that protects the epidermal cells of leaves and other organs while preventing water loss in some higher plants.

It is made up of cutin, a waxy, water-repellent compound related to suberin that is present in the corky tissue's cell walls. Hence, option c is correct.

Answer:

A compound is a molecule made of atoms from different elements

Explanation:

All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms.

Explanation:

Answer:

An acid is a compound that increases hydrogen ions (H+) when it is dissolved in a solution.

The term alkaline is related to compound that increases the hydroxide ions (OH−) when it is dissolved in a solution.

pH refers to a value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water

An ion is an atom or molecule that has a positive or negative charge.

Explanation:

Answer:

Acid A) A compound that increases hydrogen ions (H+) when it is dissolved in a solution.

Alkaline B)A compound that increases the hydroxide ions (OH−) when it is dissolved in a solution.

pH C) value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water.

Ion D) n atom or molecule that has a positive or negative charge.

Explanation:

The athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

To find the time the athlete must jog, we'll first convert the distance from kilometers to miles, then use the formula:

Time (in hours) = Distance ÷ Speed

1 kilometer is approximately 0.621371 miles.

So, the distance in miles is:

42.19 km × 0.621371 miles/km ≈ 26.21875 miles

Now, we can find the time in hours:

Time (in hours) = 26.21875 miles ÷ 9.00 mph ≈ 2.9131944 hours

To convert hours to minutes, multiply by 60:

Time (in minutes) ≈ 2.9131944 hours × 60 min/hour ≈ 174.79167 minutes

Now, let's round this to two decimal places and express the result in scientific notation:

Time (in minutes) ≈ 174.79 minutes

To write it in the requested form (using scientific notation), we move the decimal point two places to the right:

Time (in minutes) ≈ 1.7479 × 10 minutes

So, the athlete must jog for approximately 1.7479 × 10² minutes to complete a distance of 42.19 km at an average speed of 9.00 mph.

Answer:

Carbon dioxide and water enter the plant while sugars and oxygen are released into the atmosphere.

Answer:

Photosynthesis is the transformation of radiant energy to chemical energy. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air.
