Between steps 2 and 3, the chemical energy in the coal is converted to
electrical energy
mechanical energy
transitional energy
heat energy
Answers
Between steps 2 and 3, the chemical energy in the coal is converted to heat energy. So, the correct option is D.
What is Chemical energy?The bonds of chemical compounds which contain a type of potential energy known as chemical energy. It is the energy that is given out or absorbed during a nuclear rearrangement or chemical reaction.
Chemical energy is a form of potential energy, which can be released and converted into different types of energy such as heat, light or electrical energy. Some examples of chemical energy include power stored in batteries, as well as fuels such as coal, oil and gas, and food. The chemical energy in the coal is converted to thermal energy in the given above example between steps 2 and 3.
Therefore, the correct option is D.

Which particle diagram represents a mixture?
( i hope you can read it)
Answers
The diagram of the mixture is the third diagram
Explanation:
A substance that only has one kind of atom is known as an element.The element cannot be broken down further into simple substances by any physical means.A substance that only has more than one kind of atom is known as a compound.The compound can be broken down further into simple substances by chemical means.The compound has a fixed proportion of atoms of different elements.A substance that only has more than one kind of element or compound is known as a mixture.The mixture can be separated by physical means.So, from this, we can conclude that from the given particle diagrams, the diagram of the mixture is the third diagram as it has one compound molecule and two atoms of a different element.

The half life of titanium 44 is 60 years. If you start with 600 grams, how much will be left after 180 years
Answers
Answer:
[tex]75\ \text{g}[/tex]
Explanation:
t = Time = 180 years
[tex]t_{1/2}[/tex] = Half-life of titanium = 60 years
[tex]N_0[/tex] = Initial amount of titanium = 600 g
We have the relation
[tex]N=N_0e^{-\lambda t}\\\Rightarrow N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=600e^{-\dfrac{\ln 2}{60}\times 180}\\\Rightarrow N=75\ \text{g}[/tex]
The mass that is left after 180 years is [tex]75\ \text{g}[/tex].

Complete the sentence. Select all that apply. A beta particle: is electromagnetic energy is emitted from the nucleus has zero charge has a +2 charge has a -1 charge is an electron
Answers
Answer: has a -1 charge
is an electron
is emitted from the nucleus
Explanation:
The beta particle is basically an electron with -1 charge and no mass.
Beta particles are fast-moving electron emitted by radioactive decay of substances. Beta particles have a charge of - 1, and a mass of about [tex]\frac{1}{2000}[/tex] th of a proton. This means that beta particles are the same as an electron.
A beta particle, also called beta ray or beta radiation [tex](\beta)[/tex], is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.
A beta particle is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide.
As the first five elements in Group 14 are considered in order from top to bottom, there are changes in both the

B
electronegativity values and atomic radii
C
number of valence shell electrons and number of first shell electrons
D
number of valence shell electrons and atomic radii
Answers
Answer:
A
Explanation:
beacause in both the electronegativity values and number of first she'll electrons
In group 14 from top to bottom there are changes in both the electronegativity values and atomic radii changes.
What are groups?Groups in the periodic table are the columns in which elements are present which all are having same number of valence electrons.
On moving top to bottom in the 14th group of the periodic table:
Atomic size of the elements increases and electronegativity decreases.Number of electrons in the first shell of all elements will be same and in the outer most shell is also same.Hence electronegativity values and atomic radii changes.
