Explanation:

The wavelength of a wave can be found by using the formula

[tex]\lambda = \frac{c}{f} \\[/tex]

where

c is the speed of the wave

f is the frequency

From the question we have

[tex] \lambda = \frac{3 \times {10}^{8} }{5.2 \times {10}^{ 12} } \\ \\ \\ \\ \large{ = 5.77 \times {10}^{ - 5} m}[/tex]

The balanced chemical equation for the reaction of solid carbon with oxygen gas to form carbon monoxide gas is  2 C + O₂[tex]\rightarrow[/tex] 2 CO.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Answer:

The third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) And 2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth.

When tiny droplets of one liquid are finely dispersed within another liquid it is called emulsion.

Emulsion can be defined as the process by which two liquids that are not miscible come together to form a mixture.

The emulsion mixture usually consists of an oil phase and a water phase.

The oil phase appears as droplets when dispersed (mixed with) the water phase.

The uses of emulsion include:

Answer:

96mg

Explanation:

Since the half-life of Palladium-100 is 4 days and the sample has been reduced after 16 days, that means the sample has undergone four half-lives. To find the intial mass, just work backwards:

As you see, I've worked backwards from the four half-lives. So the initial mass after 16 days is 96 mg.

Answer: hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force.

Explanation:

An atom of ordinary hydrogen consists of one electron and one proton and zero neutrons.

Hydrogen is a chemical element placed at the top of group 1 in the periodic table and is represented by the chemical symbol H and atomic number 1.

A hydrogen atom is the lightest atom of the element in the whole periodic table. Hydrogen exists as a gas of diatomic molecules having the formula H₂ at standard conditions. Hydrogen gas is tasteless, colorless, odorless, non-toxic, and highly combustible.

Hydrogen is constituting roughly 75% of all normal matter and is the most abundant chemical substance in the universe. Most of the hydrogen element on Earth exists in forms like water and organic compounds.  Each atom of hydrogen (¹H) has one proton, one electron, and no neutrons.

Hydrogen element is nonmetallic and easily forms a single covalent bond with most nonmetallic elements, forming compounds like water.
