Answer:

Yes, it will.

Explanation:

The friction of the surface will tug at the book and lower it's velocity, causing it to slow down.

Friction always acts to oppose any relative motion between surfaces.

If we push on the book with a force of less than 5 N, the book won't move, because the frictional force will exactly balance the force we apply. If we push with a 1 N force, a 1 N frictional force opposes us.

What rules should you follow when adding and subtracting ?
wariber [46]
Adding and subtracting with scientific notation may require more care, because the rule for adding and subtracting exponential expressions is that the expressions must havelike terms<span>. Remember that to be </span>like terms<span>, two expressions must have exactly the same base numbers to exactly the same powers. Thinking about decimal arithmetic, the requirement that we have the same powers makes sense, because that guarantees that all of the place values are lined up properly.</span>

A _____ exists in the same physical state as that of the reaction it catalyzes.
klio [65]
<span>A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.

Explanation:
                     
Catalysts are classifies as follow,
                                                      1. Homogeneous Catalyst
                                                      2. Heterogeneous Catalyst

</span>Homogeneous Catalyst are those which are in same phase as that of reactants are.

Example:

         Acetic Acid + Ethanol + H₂SO₄  →  Ethyl Acetate + H₂O + H₂SO₄

In this reaction catalyst and reactants all are in same phase i.e. Liquids.

Heterogeneous Catalyst are those which are in different phase as that of reactants are.

Example:

                                 Ethene + H₂ + Ni  →  Ethane + Ni

In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.

What’s are the different Types of chemical weathering
Ira Lisetskai [31]

Answer:

Types of chemical weathering

1. Hydrolysis

2. Oxidation

3. Carbonation

4. Acid rain

5. Acids produced by lichens

Explanation:

Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.

Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.

Oxidation : is when oxygen reacts with rocks eg. rust formation

Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.
