Answer:carbon-14 levels in the atmosphere

Explanation:

When carrying out radiocarbon dating, the level of carbon-14 in a sample is compared with the level of carbon 14 in the atmosphere because, objects exchange carbon-14 with the atmosphere.

Comparison of the activities of carbon-14 in the atmosphere and in the sample gives the age of the sample since the half-life of carbon-14 is a constant.

Combustion is a types of reactions which would result in the production of gas. Chemical reaction, the transformation of one or more chemicals into one or more distinct compounds.

Chemical reaction, the transformation of one or more chemicals (the reactants) into one or more distinct compounds (the products). Chemical elements or chemical compounds make up substances. In a chemical reaction, the atoms that make up the reactants are rearranged to produce various products.

Chemical reactions are indeed a fundamental component of life itself, as well as technology and culture. Hydrocarbon - based, smelting iron, creating glass but also pottery, brewing beer, making wine, and making cheese are just a few examples of ancient processes that involved chemical reactions. Combustion is a types of reactions which would result in the production of gas.

Therefore, combustion is a types of reactions which would result in the production of gas.

The smaller the radius, the higher the ionization energy. This is because the electrons are being held in closer to the protons, which have opposing charges and therefore hold on to them, in an atom with a small radius.

Answer:

16.68 m/s

Explanation:

The following data were obtained from the question:

Height (h) = 14.2 m

Initial Velocity (u) = 0 m/s

Final velocity (v) =?

Thus, the velocity (v) with which the ball hit the ground can be obtained as follow:

v² = u² + 2gh

NOTE: the acceleration due to gravity (g) = 9.8 m/s²

v² = u² + 2gh

v² = 0² + 2 × 9.8 × 14.2

v² = 0 + 278.32

v² = 278.32

Take the square root of both side

v = √278.32

v = 16.68 m/s

Therefore, the velocity with which the ball hit the ground is 16.68 m/s

Answer:

D

Explanation:

Seeing the Lewis formula for each of the molecules, we can attempt to write the condensed structural formula for each.

What we notice is that while there are purely single bonds between the carbon atoms in the first molecule, there is a double bond in the second molecule and a triple bond in the third

What we can deduce from this is that these are alkanes , alkenes and alkynes

The alkynes have the strongest of the three bonds and thus they have the strongest bonds in the mix

Since molecule 3 is an alkyne, then we can say that it has the strongest of the bonds

The correct claim about the molecules that best supports the diagrams is :

( D ) The strongest carbon to carbon bond occurs in molecule 3  

The first molecule ( molecule 1 ) is an alkane because the molecule is made up of only single bonds connecting the carbon atoms.

while the second mole ( molecule 2 ) is an alkene because of the presence of a double bond connecting carbon atoms.

and the third molecule ( molecule 3 ) is an alkyne because of the presence of a triple bond connecting carbon atoms.

Therefore  Alkynes have the strongest of of bonds between its carbon atoms  because of the presence of a triple connecting carbon atoms.

Hence we can conclude that The strongest carbon to carbon bond occurs in molecule 3

Answer:

Thomson passed an electric current through sealed glass tubes filled with gases. Thomson concluded that electrons must be parts of the atoms of all elements. Millikan determined the charge and mass of the electron.

Explanation:

Thompson discovered electrons and proposed the plum - pudding model of the atom. Millikan measured the charge to mass ratio of an electron.

In the early days of the atomic theory, working with his cathode ray tube, J.J Thompson discovered electrons. His discovery of electrons led him to propose a model which depicted the atom as a sphere of positive charges into which negative charges were embedded. This is the plum-pudding model of the atom.

Using his famous oil-drop experiment, R.A Millikan successfully measured the charge to mass ratio of the electron and thereby determined the magnitude of charge on the electron.

Answer:

313.5cm²

Explanation:

Given parameters:

Weight of model  = 105pounds

Pressure applied on the scale by model = 2.16pounds per square inch

Unknown:

Area of her feet in cm² = ?

Solution:

Pressure is the force per unit area;

     Pressure  = [tex]\frac{Force}{Area}[/tex]

Input the parameters and solve;

                2.16  = [tex]\frac{105}{Area}[/tex]

       105  = 2.16 x Area

        Area = [tex]\frac{105}{2.16}[/tex]   = 48.6in²

We need now to convert the in² to cm²

          1in² = 6.45cm²

        48.6in² = 48.6 x 6.45  = 313.5cm²

A homogeneous mixture can be described as the solute uniformly dissolving in a solvent to make a solution. Therefore, option (B) is correct.

A mixture can be described as a combination of two or more substances that are not chemically combined with each other. Mixtures can be categorized into two kinds homogeneous mixtures and heterogeneous mixtures.

A homogeneous mixture can be defined as one whose whole composition is uniform throughout the entire mixture. It can be the type of mixture where the entire composition is constant throughout that make up the mixture and is distributed uniformly.

A homogeneous mixture can be described as a gaseous, liquid, or solid mixture that has equal proportions of its components throughout the sample. In a homogeneous mixture, there is only one phase of matter observed.

Some examples of Homogeneous Mixtures are Air Rainwater, Vinegar, Dishwashing detergent, Steel, Sugar water, a Cup of Coffee, etc.
