2. Makes accurate predictions based on only a small amount of empirical evidence

Explanation:

For a phrase or scientific finding to be considered a law, there has to be clear evidence and facts to support that specific finding. In the case of the evolution theory, the evidence is not clear enough to make it a law

Answer:

Chemical symbol

This is used to identify an element without having to write the full name and as such is a designation for the element. It is used in chemical reactions and is usually either one or two letters. Some symbols are, Iron - Fe, Hydrogen - H and Oxygen - O.

Valency

This refers to the capacity of an element to combine with another to form a compound. It is measured by the number of electrons that an atom of an element gains, looses or shares when a chemical reaction involving it takes place.

Answer:

A. The kinetic energy increases as its speed increases.

Explanation:

The kinetic energy of an object is energy possessed by an object by virtue of its motion.

Now, kinetic energy of a moving body is given by;

KE = 1/2 mv^2

Where;

m = mass of the body

v = velocity (speed) of the body

It follows that if the mass of the spaceship is constant, a sudden increase in speed leads to a corresponding increase in the kinetic energy of the spaceship in accordance with the relationship show above.

Answer:

You'll speed up! A. Because the kinetic energy increases as its speed increases.

Explanation:

Names for such acids consist of the prefix “hydro-“, the first syllable of the anion, and the suffix “-ic”. Complex acid compounds have oxygen in them. For an acid with a polyatomic ion, the suffix “-ate” from the ion is replaced with “-ic.”

On rare occasions, aremnant of the tail through and embryological development, although this tale of course has no function. An embryos splits are found in the boreals of all vertebrates because they share a common ancestors with fish and which structures first

Answer:

moles or atoms?

Explanation:

you can't have a molecule of any so there's two different answers that I can give you:

how many moles? 1.5

how many atoms? 9.03x10^23 atoms

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x1023 atoms/mole = 9.03x1023 atoms

9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP. At STP 1 mole of an ideal gas occupies 22.4L.

The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.

Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. Compared to electrons, that are the smallest charged particles in nature, the nucleus is tiny and dense.  

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x10²³ atoms/mole = 9.03x10²³ atoms

Therefore, 9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP.

Answer:

This is Newtons 2nd Law: Force is directly proportional to the acceleration of the object, acceleration is inversely proportional to the mass of the object.

Answer:

D. Carbon Dioxide

Explanation:

Carbon is what enters the plant. It isn't a product of the plant.

Answer:

false it is a chemical change

Answer:

It gains electrons.

Explanation:

Got it right on a quiz.

When electrons are added to or taken away from an object, an electrical charge is produced. An object acquires a negative charge when electrons are introduced to it because electrons have a negative charge. An object acquires a positive charge when its electrons are removed.

When a thing picks up electrons, it becomes negatively charged. Non-metals gain electrons at the atomic level to fill their outer electron orbitals. An atom that is negatively charged and has more electrons than protons is said to be an anion.

Some atoms have the ability to draw in more electrons, making them negatively charged. Ions are defined as atoms that are not electrically neutral.

Answer:

54.5%

Explanation:

The percentage composition of oxygen in C₆H₈O₆ can be obtained as follow:

Molar mass of C₆H₈O₆ = (12×6) + (8×1) + (16×6)

= 72 + 8 + 96

= 176 g/mol

Next, there are 6 oxygen atoms in C₆H₈O₆. Therefore the mass of oxygen in C₆H₈O₆ is:

Mass of Oxygen = 16 × 6 = 96 g

Finally, we shall determine the percentage composition of oxygen in C₆H₈O₆ as follow:

Percentage of oxygen =

Mass of Oxygen/mass of C₆H₈O₆ × 100

Percentage of oxygen = 96 / 176 × 100

Percentage of oxygen = 54.5%

Thus, the percentage composition of oxygen in C₆H₈O₆ is 54.5%.

Answer:

Error or mistakes during DNA replication is accountable for two-thirds or 66% of the cancer cases. These random and unpredictable errors called mutations that occur during the division of a cell as an error in copying of DNA.

DNA replication has three main steps:

Opening and separation of DNA strands of a helix - carried by an enzyme known as helicase that breaks the hydrogen bonds between nitrogenous bases of the helix of DNA.

The priming of the template strand - DNA primase helps RNA primers to bind to both strands at 3' end as soon as it separated

strat assembling the segments of new DNA on strands called elongation of the strands with help DNA polymerase I and after forming new strands the termination of the replication.

Errors or mistakes can occasionally take place if DNA polymerase inserts a wrong base during elongation of the strands.

Answer:

Chemicals A and B form an endothermic reaction, and chemicals C and D form an exothermic reaction.

Explanation:

The reaction that produced chemical C is an endothermic reaction whereas, the reaction between C and D is an exothermic one.

An exothermic change is one in which heat is liberated to the surroundings. So the surrounding becomes hotter at the end of the reaction.

An endothermic reaction is a change in which heat is absorbed from the surrounding and hence the surrounding colder at the end of the change.

Answer:

Explanation:

Chemicals A and B form an exothermic reaction, and chemicals C and D form an endothermic reaction.

Chemicals A and C form an endothermic reaction, and chemicals B and D form an exothermic reaction.

Chemicals A and B form an exothermic reaction, and chemicals B and D form an endothermic reaction.

See the answer below

Explanation:

1. Organisms produce energy for cells by chemically breaking down and unlocking the energy locked-up within food materials in a process known as cellular respiration. The unlocked energy is then utilized for the cell's metabolic activities.

2. Cellular respiration can be aerobic or anaerobic.

Aerobic respiration involves the breakdown of carbohydrates in the presence of oxygen to yield energy in the form of ATP while carbon dioxide and water are produced as by-products.

        [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

Anaerobic respiration involves the breakdown of carbohydrates in the absence of oxygen to produce ATP and lactic acid as a by-product. The lactic acid is later oxidized to carbon dioxide and water to prevent it from building up.

       [tex]C_6H_1_2O_6 -> 2C_3H_6O_3 + ATP[/tex]

3. Photosynthesis and cellular respiration are both considered metabolic processes that take place in living organisms. However, photosynthesis is peculiar only to green plants and some algae while respiration is common to all living organisms. While photosynthesis is anabolic, that is, it involves the building up of materials; respiration is said to be catabolic because it involves the breaking down of materials.

During photosynthesis, inorganic products are utilized to produce carbohydrates for plants with oxygen gas released as a by-product according to the following equation:

       [tex]6CO_2 + 6H_2O --> C_6H_1_2O_6 + 6O_2[/tex]

During respiration, the food taken by living organisms is broken down to unlock the energy in it for metabolic activities according to the following equation:

     [tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]
