Answer:

2.8g/cm³

Explanation:

Given parameters:

Mass of cube = 42g

Volume of cube  = 15cm³

Unknown:

Density of the cube  = ?

Solution:

Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:

 Density  = [tex]\frac{mass}{volume}[/tex]  

So;

 Density  = [tex]\frac{42}{15}[/tex]   = 2.8g/cm³

Answer:

B. 3+

Explanation:

When Fe²⁺ loses an electron, it becomes an Fe³⁺ ion.

   The loss of an electron in an atom makes the atom becomes positively charged. Further losing electrons makes the atom more positive.

 For the given ion;

 Fe²⁺   if it loses an electron more, it becomes Fe³⁺.

The expression is given as:

         Fe²⁺    →    Fe³⁺  +  e⁻

Answer:

C. Equations that separate the oxidation and reduction parts of the reaction.

Explanation:

Redox half-reactions are actually used when balancing redox reactions. It gives the oxidation or reduction reaction components/parts of a redox reaction.  The change in oxidation and reduction states in the substances that are involved in a redox reaction is used to obtain a redox half-reaction.

This redox half-reaction can also be used to explain what takes place in an electrochemical cell; how the anode is undergoing oxidation and how the cathode is undergoing reduction.

Below is an example of a redox half-reaction:

2 Fe³⁺(aq) + 6e⁻ → 2 Fe(s) (Reduction)

3 Mg(s) → 3 Mg²⁺(aq) + 6e⁻ (Oxidation)

Explanation:

It is based on empirical evidence

The characteristic of science is that it is based on empirical evidences comprising of a hypothesis.

Hypothesis can be defined as an assumption which is made for the sake of argument . It is an interpretation of a practical condition for which action needs to be taken.It is defined as a tentative assumption which is made to test logical consequences.It is an antecedent clause of a statement which is conditional.

It is constructed before research. There are six types of hypothesis 1)simple hypothesis 2) complex hypothesis 3) directional hypothesis 4)non-directional hypothesis 5) null hypothesis 6)casual hypothesis

The hypothesis should be clear and precise, it must be specific and way of explanation of hypothesis should be simple.

Answer:

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Explanation:

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

Answer:

Water can be used as the thermometric liquid. It expands and contracts with temperature so it can be used. It's just not a very good choice because: It's thermal expansion is not very large compared to other liquids like mercury.

Answer:

B. A carbon monoxide molecule(CO)

Explanation:

CO is polar because oxygen is more electronegative than carbon, so it gives oxygen a partial negative charge and carbon and partial positive charge. This causes a net dipole moment. CO2 is linear with no net dipole moment because each C-O bond is equal and opposite to each other, so they equal 0, which makes them non polar.

Answer:

Weaker

Explanation:

Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).

Here, we are required to determine if the attraction or repulsion grow weaker or stronger.

First, we must establish scenarios when there can be attraction and ones where there can be repulsion.

By the law guiding electric charges; In electrical interactions:

Like poles repel while Unlike poles attract.

Ultimately, when an electron gets closer to the nucleus, the attraction force will grow stronger due to the reduced distance between the electron and the nucleus.

Explanation:

Answer:

278.1g/mol

Explanation:

To find the molar mass of the given compound, we must know the atomic mass of the elements within the compound.

Atomic mass of Mg = 24.3g/mol

Atomic mass of I  = 126.9g/mol

So;

  Molar mass  = 24.3 + 2(126.9) = 278.1g/mol

The molar mass of the compound is  278.1g/mol

Answer:

63.6%

Explanation:

The given compound is:

     N₂O;

The problem here is to find the percent composition of nitrogen in the compound.

First find the molar mass of the compound:

 Molar mass of N₂O = 2(14) + 16  = 44g/mol

So;

 Percentage composition of Nitrogen  = [tex]\frac{2 x 14}{44}[/tex]  x 100  = 63.6%

Answer:

3.39 x 10²³ particles

6.02 x 10²²particles

Explanation:

The problem here entails we find the number of particles in the given substances.

From the mole concept;

          1 mole of a substance contains 6.02 x 10²³ particles

a. 18g of O₂;

 We first find the number of moles of this substance first;

       Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

  Molar mass of O₂   = 2(16) = 32g/mol

      Number of moles  = [tex]\frac{18}{32}[/tex]   = 0.56mole

 So;

             1 mole of a substance contains 6.02 x 10²³ particles

            0.56 mole of  O₂ will contain 0.56 x 6.02 x 10²³ particles

                                                                   = 3.39 x 10²³ particles

b. 0.1mole of calcium atom:

        1 mole of a substance contains 6.02 x 10²³ particles

       0.1 mole of the substance will contain 0.1 x  6.02 x 10²³ particles

                                                                         = 6.02 x 10²²particles

Answer:

B. bedrock structure.

Explanation:

A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.

Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.

A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.

The Catskills are commonly called mountains but are actually part of the Allegheny Plateau also referred to as Appalachian Plateau. The Catskills are classified as a plateau because of their bedrock structure which is caused by a valley, continental glaciers, and erosion from various watercourse.

Additionally, the Catskills is a mountain which got its name from early Dutch settlers in the United States of America.
