Using triangulation which point is the earthquakes epicenter?

Answer:

The transformation is of chemical energy (use the ATP molecule as a resource) which is then transformed into mechanical energy (muscle contraction) and finally transformed into thermal energy (increase in body temperature, or sweating)

Explanation:

Energy is never lost, it is always transformed, that is why energy is yielding electronic movement and expressing itself in different ways, first as chemical energy, then as mechanical energy, and lastly as thermal energy.

It is important to clarify that the energy source of all this transformation is food and energy reserves.

Answer:

polar covalent

Explanation:

If they do not equally share the electron then it is polar and covalent bonds share electrons

Answer:

The correct options are;

1) Heat

2) Atoms

Explanation:

The heat required to raise a unit mass of a substance by one degree which is the specific heat capacity of the substance, is a quantity characteristic of a given substance and the amount of temperature change experienced by the substance when an amount of heat energy transferred to the substance is a function of the mass of the substance, which is a function of the number of atoms present in the substance.

So also, the total thermal energy that is stored by a substance, that causes a given amount of temperature change, is a function of the heat capacity of the substance.

Answer: One of the most striking features of many protist species is the presence of some type of locomotory organelle, easily visible under a light microscope. A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia. Those same organelles may be used in feeding as well.

Answer:

NH4Cl (s) → NH3 (g) + HCl (aq)

Answer:

15 atoms total

Explanation:

2 Al atoms + 3 O atoms = 5 Al2O3 atoms

5 Al2O3 atoms * 3 = 15

another way to do it is:

2 Al atoms * 3 = 6 Al atoms

3 O atoms * 3 = 9 O atoms

6+9 =15 atoms total

The number of atoms in the given 3Al₂O₃ is 15 atoms.

Atoms are the smallest unit of every matter. It contains charged particles present inside the atoms. They are electrons, protons, and neutrons. Atoms are of four types, description, isotopes, radioactive, and ions.

These atoms are the ions, that are charged, and the charged ions make bonds with each other to form compounds. Aluminum oxide is a compound that is formed by combining aluminum and oxygen atoms.

The compound is 3Al₂O₃

This means there are three moles of aluminum, and three moles of oxygen.

2 Al atoms + 3 O atoms = 5 Al₂O₃ atoms

5 Al₂O₃ atoms x 3 = 15

The elaborative way is:

2 Al atoms x 3 = 6 Al atoms

3 O atoms x 3 = 9 O atoms

6 + 9 =15 atoms total

Thus, the number of atoms is 15 atoms.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

This strange green slime is a colonization of fungi caused by the humidity of the bathrooms, which to be eradicated requires a non-specific antimicrobial such as sodium hypochlorite that generates an osmotic imbalance producing a fungicidal effect.

Explanation:

The fungi that appear in the form of slime at the microscopic level have many forms of colonization, by adding coconut milk it was assumed that this would generate an environment not suitable for their metabolism and reproduction but this did not happen, therefore they continued their reproduction.

Explanation:

Given parameters:

Distance covered by the train  = 813.5miles

Time taken  = 5hours

Unknown:

Speed of the train  = ?

Solution:

Speed is a physical quantity.

It is mathematically expressed as;

      Speed  = [tex]\frac{distance}{time}[/tex]

So, input parameters and solve;

   Speed  = [tex]\frac{813.5}{5}[/tex]  = 162.7miles/hr

The ground state configuration : 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹

Electrons can move the shell up or down by releasing energy or absorbing energy  

It can be concluded that there are 2 conditions:  

Ground-state is the state of electrons filling the shell with the lowest energy levels.  

Excited-state is the state of electrons which occupies a higher energy level  

The state of excited electrons can be seen from the presence of electrons which do not fill the shell completely but fill the shell afterward  

Gallium (Ga) is a metal located in group 13, p-block and  period 4

Atomic number : 31

If we look at the options:

options 1,2 and 3 do not conform to Aufbau principle(Electrons occupy orbitals of the lowest energy level  ), because 3d orbitals do not exist and the number of electrons is also not 31

So that the most appropriate electron configuration is:

1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹ = 31 electrons

or we can write : [Ar] 4s² 3d¹⁰ 4p¹

sulfur

Explanation:

From the given lists of elements, the one with the most electronegativity is Sulfur.

  Electronegativity is of an element is a property that combines the ability of its atom to lose and gain electrons.

It is a measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.

Using the Pauling's electronegative table of elements;

   Here are electronegativity values of the given elements;

selenium                 2.4

arsenic                    2.0

phosphorus            2.1

sulfur                      2.5

We see that the value of sulfur is the highest.

A. The chemical changes occurred because the chemicals changed.

Explanation:

When baking a cake several chemical reactions occur that change the chemical composition of the ingredients used in baking. An ingredient like baking powder releases carbon dioxide when it undergoes a temperature change in the oven. A chemical change is supposed to change the form of a substance.

An endothermic reaction also occurs when the ingredients absorb heat energy to produce several changes. The firmness of the cake occurs because of the heat absorbed by the proteinous content of the egg.

Answer:

Barium Sulfite

Explanation:

Barium Sulfite

The IUPAC name for BaSO₃ is barium sulfite.

"Ba" stands for barium, which is the chemical symbol for the element with atomic number 56. Barium is an alkaline earth metal and belongs to Group 2 of the periodic table.

"SO₃" stands for sulfite, which is a polyatomic ion composed of one sulfur atom (S) and three oxygen atoms (O). The chemical formula for the sulfite ion is SO₃²⁻. The sulfur atom in the sulfite ion has a +4 oxidation state.

When barium (Ba) reacts with the sulfite ion (SO₃²⁻), they combine to form barium sulfite (BaSO₃). The balanced chemical equation for the reaction is:

Ba²⁺ + SO₃²⁻ → BaSO₃

Barium sulfite is an ionic compound, where the Ba²⁺ ion and the SO₃²⁻ ion are held together by electrostatic attractions (ionic bonds). In its solid form, barium sulfite appears as a white crystalline powder.

Answer:first one

Explanation:

A pure substance has same chemical properties throughout , it cannot be  separated by any means and it is made up of one kind of atom.

These properties are defined as those properties which become evident during or after a chemical reaction after the identity of the substance is changed during chemical reaction.

These properties cannot be determined externally just by viewing the substance ,these change immensely after a substance undergoes a chemical change.These are used for identification of unknown substances and for building up chemical classifications.

The major chemical properties are flammability,toxicity,reactivity,acidity and heat of combustion.For a chemical property to be apparent , it is necessary that the structure of the substance is altered.
