Definition

The Cretaceous/Tertiary boundary (KT), also often called the Cretaceous/Paleogene (K/Pg) boundary, marks the contact between the Mesozoic and Cenozoic eras ∼ 65 Ma ago. The KT boundary is characterized by the last major mass extinction in Earth history that saw the demise of the non-avian dinosaurs along with 50% to 60% of the Earth fauna and flora.

Answer:

B) -4.1 units

Explanation:

According to this question, a state property X has a value 89.6 units. It undergoes the certain changes as follows:

- first increase by 3.6 units

- then increase by another 18.7 units

- then decrease by 12.2 units

- and finally attains a value of 85.5 units

This can be mathematically represented by 89.6 - {3.6 + 18.7 - 12.2 - x) = 85.5

To get x, we say;

89.6 + 3.6 = 93.2

93.2 + 18.7 = 111.9

111.9 - 12.2 = 99.7

99.7 - 85.5 = 14.2units.

The changes that occured is represented as follows:

= (3.6 + 18.7) - (12.2 + 14.2)

= 22.3 - 26.4

= -4.1 units

Answer:

What is the Rome was not built in one day with speech

Answer:

The final temperature of the mixture is 22.3°C

Explanation:

Assuming that the 120 g substance at 80°C is water, final temperature of the mixture can be determined using the formula:

Heat lost = Heat gained

Heat = mc∆T where m is mass, c is specific heat capacity of water, and ∆T is the temperature change = Tfinal - Tinitial.

Let the final temperature be T

Heat lost = 120 × c × (T - 80)

Heat gained = 3000 × c × ( T - 20)

Equating the heat lost and heat gained

120 × c × -(T - 80) = 3000 × c × (T - 20)

9600 - 120T = 3000T - 60000

60000 + 9600 = 3000T + 120T

69600 = 3120T

T = 69600/3120

T = 22.3°C

Therefore, the final temperature of the mixture is 22.3°C

Answer:

58.944 g

Explanation:

From the question given above, the following data were:

Mole of SO2 = 0.9210 mole

Mass of SO2 =?

Next, we shall determine the molar mass of SO2. This can be obtained by adding the molar mass of sulphur and oxygen together as illustrated below:

Molar mass of SO2 = 32 + (2 × 16)

= 32 + 32 = 64 g/mol

Finally, we shall determine the mass of 0.9210 mole of SO2 as follow:

Mole of SO2 = 0.9210 mole

Molar mass of SO2 = 64 g/mol

Mass of SO2 =?

Mole = mass /Molar mass

0.9210 = mass of SO2 / 64

Cross multiply

Mass of SO2 = 0.9210 × 64

Mass of SO2 = 58.944 g

Thus, the mass of SO2 is 58.944 g.

Experiments with gold foil indicated that atoms contain a positively charged, dense center and the correct option is option C.

Experiments with gold foil, known as the Rutherford gold foil experiment, were conducted by Ernest Rutherford in 1911. In this experiment, he bombarded a thin gold foil with alpha particles.

Most of the alpha particles passed through the foil with little deflection, but some of them were deflected at large angles, and a small fraction even bounced back. This observation led Rutherford to conclude that the atom contains a positively charged, dense center called the nucleus, where most of its mass is concentrated. He proposed the nuclear model of the atom, which became a significant advancement in the understanding of atomic structure.

Thus, the ideal selection is option C.

Answer:

The product of the synthesis reaction is CaI.

Explanation:

In chemistry, chemical equations are the representation of chemical reactions between elements, compounds, substances, or molecules.

They are written using element symbols (and sometimes including their current state of matter).

Therefore, if we wanted to show the reaction of sodium and chlorine to make sodium chloride, or table salt, we would illustrate it as such:

[tex]\bullet \ \text{Na + Cl} \rightarrow \text{NaCl}[/tex]

A synthesis reaction in chemistry is the combination of two or more elements, compounds, molecules, or substances to make one compound, molecule, or substance.

The parent equation for a synthesis reaction is:

[tex]\bullet \ \text{A + B}\rightarrow \text{AB}[/tex]

Therefore, we need to find out what the element symbols are for both calcium and iodine.

If we reference a periodic table, we will see that calcium is atomic number 20 and has the symbol Ca.

Additionally, when we locate iodine, we will see that it is atomic number 53 and has the atomic symbol I.

Now, we just need to create the reaction equation.

[tex]\text{Ca + I}\rightarrow \text{?}[/tex]

We know that we are dealing with a synthesis reaction, or a combination, so the elements will combine to make one substance.

With this information, we can make an equation:

[tex]\text{Ca + I} \rightarrow \text{CaI}[/tex]

Therefore, the product of the synthesis reaction is CaI.

Note: Please note that "I" is an uppercase i.

The reduction half-reaction of a redox reaction

Explanation:

(just took the test)

The reduction of half-reaction of a redox reaction. Hence, option B is correct.

An electrolytic cell converts electrical energy into chemical energy or vice versa.

A galvanic cell is an electrochemical cell in which chemical energy is converted to electrical energy. The chemical reaction which drives a galvanic cell is a redox reaction i.e. a reduction-oxidation process.

A typical galvanic cell is composed of two electrodes immersed in a suitable electrolyte and connected via a salt bridge. One of the electrodes serves as a cathode where reduction or gain of electrons takes place. The other half cell functions as an anode where oxidation or loss of electrons occurs. Batteries and fuel cells are examples of galvanic cells.

Hence, option B is correct.

In the given unbalanced reaction, the number of sodium is not balanced. There must have two sodium in the product side also. The correct formula of sodium sulphate is Na₂SO₄.

According to the law of conservation of mass, the total mass of a system is conserved. Thus, mass can neither be created nor be destroyed. Therefore, for a chemical reaction, the total mass in the product side must be equal to the total mass in the reactant side.

The balanced equation of  a chemical reaction thus, obeying the mass conservation law where, each element have to be equal in number in both sides.

In the given reaction, the number of Na in reactant side is 2 and that in product side is 1 only. Thus total mass of sodium is not conserved. It can be corrected as Na₂SO₄ in the product side.

Answer:

Protons = 3

Neutrons = 4

Electrons = 3

Explanation:

For every atom, the atomic number is equal to the number of protons.

In a neutral atom (atom with no charge) the number of protons is equal to the number of electrons.

To calculate neutrons subtract the number of protons (atomic number) from the rounded molar mass:

7 - 3 = 4 neutrons

Recall that the main function of chloroplasts is to convert sunlight to chemical energy, or to carry out photosynthesis.  Plant (and eukaryotic algae) cells contain these organelles, while animal cells do not, and hence, animals cannot carry out photosynthesis.

So, a lack of chloroplasts would mean that an organism would not be able to convert sunlight into chemical energy through photosynthesis.

Plants cells, and specifically the chloroplast organelle, are able to absorb sunlight, and together with CO₂ and water, produce glucose (for the plant to eat) and oxygen (which is released into the atmosphere).  That glucose is further broken down by the plants' mitochondria.  Animals directly consume the glucose to be broken down and converted into energy, hence why we do not have - nor need - chloroplasts in our cells.

The factor of matter are solubility, boiling point, melting point, temperature, density and reactivity
