Answers
Answer:
the first energy level is closest to nuclear the second energy level is a little farther away than the first
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, The energy level where an electron is located, is shown by the period on the periodic table
What is periodic table?Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
The energy level where an electron is located, is shown by the period number on the periodic table. The number of the period represents the number of orbits or shells. Shells represents the energy levels of an element.
Therefore, the energy level where an electron is located, is shown by the period on the periodic table.

Answers
Answer:
Synthesis
Explanation:
The reaction:
2Mg + O₂ → 2MgO
This reaction above is a synthesis or combination reaction. In such reaction, several products combines to give a single product.
The formation of a single product from two or more reactants is classified under this type of reaction
The driving force for this reaction type is the large and negative heat of formation of the product.
Why are the bacteria in a termite’s stomach considered mutualistic and not parasitic?
Answers
In commensalism the smaller partner benefits from the relationship, with no fitness effect on the host. There are fitness gains for both partners in mutualism, and a parasite benefits by exploiting but not directly killing its host.

After a certain pesticide compound is applied to crops, its decomposition is a first-order reaction with a half-life of 56 days. What is the rate constant, k, for the decomposition reaction?
Answers
The rate constant, k, for the decomposition reaction : k = 0.0124 / days
Further explanationGiven
The half-life of 56 days
Required
The rate constant, k
Solution
For first-order, rate law : ln[A]=−kt+ln[A]o
The half-life : the time required to reduce to half of its initial value.
The half life :
t1/2 = (ln 2) / k
k = (ln 2) / t1/2
k = 0.693 / 56 days
k = 0.0124 / days
The rate constant for the decomposition reaction has been 0.0124/days.
The rate constant has been given by;
log [Final concentration] = kt + log [Initial concentration]
k has been the rate constant, and t has been the time.
The initial concentration has been 1, after the half life period the concentration has been half i.e. 0.5 .
The given half life has been 56 days.
The rate constant can be calculated as:
log 1 = k(56) + log 0.5
k(56) = 0.693
k = 0.0124/days.
The rate constant for the decomposition reaction has been 0.0124/days.

Beryllium has a specific heat of 1.825 J/(g . °C). How many joules of heat energy are required to raise the temperature of 2.300 grams of beryllium from 22.00 to 60.00°C?
Answers
Heat required to raise the temperature = 159.505 J
Further explanationGiven
c = specific heat of Beryllium = 1.825 J/g C
m = mass = 2.3 g
Δt = Temperature difference : 60 - 22 = 38 °C
Required
Heat required
Solution
Heat can be formulated
Q = m.c.Δt
Input the value :
Q = 2.3 x 1.825 x 38
Q = 159.505 J
What is the relationship between temperature and reaction rate?
Answers
Explanation:
Temperature has a direct relationship with reaction rate. The higher the temperature the faster the rate of reaction of a system.
For every 10°C rise in temperature above the room temperature, it has been found that reaction rates becomes double or triple. When the temperature of a reacting system increases, the kinetic energy of each of the reacting particles increases. The frequency of collision and effective collision also increases per unit of time. Many of the reacting particles will acquire an energy greater than or equal to the activation energy of the reaction.Calculate the mass of 4.60 x 10^25 atoms of neon?

What is element?A material is considered an element if it cannot be divided into two or even more simpler compounds by any kind of chemical process, including the use of light or warmth. For instance, when melting the chunk of gold, it nevertheless melts but remains as the precious metal element.
The fundamental components of matter are thought to be the elements. There are currently 118 known elements, 94 of which are found in nature while the remaining 24 are created artificially. [Kr]5s²4d10⁵p² represents iodine element.

how much energy would be lost by 23 g of water if it was heated until it was 78 degrees celsius and then allow to cool down to 27 degrees celsius
Answers
Answer:
Q = -4903.14 j
Explanation:
Given data:
Mass of water = 23 g
Initial temperature = 78°C
Final temperature = 27°C
Heat lost = ?
Solution:
Specific heat capacity of water is 4.18 J/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 27°C - 78°C
ΔT = -51°C
Q = 23 g × 4.18 J/g.°C × -51°C
Q = -4903.14 j (negative sign shows heat is released)

Answers
Answer:
Hydrogen = element
Carbon dioxide = compound
Water = compound
Zinc = element
Nitrogen = element
Salt = compound
Helium = element
Carbon monoxide = compound
Explanation:
An element and a compound are different when it comes to the types of atoms they possess. An element has only one type of atom while a compound has two types of atoms. For example, Hydrogen is an element because it has two atoms of the same type and that is, the "Hydrogen atom."
On the contrary, Carbon dioxide has one carbon atom and two atoms for Oxygen. Therefore, it is a compound because it has two types of atoms: Carbon atom and Oxygen atom.
Water has two atoms of Hydrogen and one atom of Oxygen. Therefore, it is a compound because it has two types of atoms: Hydrogen atom and Oxygen atom.
