Answer:
The correct approach is Option B (Peer Review).
Explanation:
Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.Other approaches do not apply to the example mentioned. Although the one mentioned is right.

THANKYOU
USE COPPER OXIDE IONS AS AN EXAMPLE.
7-8 POINTS
Answer:because some have more radiation than others causing mutations and there for either decreasing or increasing the amount of ions
copper is a acidic metal in general therefor it will most likely erode faster than any other metal making it hard to determan the number of ions in general the metal will have basicly what I’m trying to say is there is no solid answer as many metals can change there ions for no given reason
Explanation:
An atom has 30 protons, 30 neutrons, and 30 electrons. What is the charge of the atom’s nucleus?
A: +30
B: +60
C: -30
D: -90
Answer:
+30
Explanation:
The nucleus holds both protons and neutrons. Since a neutron is neutral there is no charge. Protons are a positive charge. so the atoms nucleus is +30.
The charge on an atom's nucleus is the same as the number of protons in the nucleus. The charge on the nucleus of the atom is +30.
The nucleus houses positive particles called protons. Each proton carries a charge of +1.
The magnitude of charge of the nucleus is the same as the number of protons in the nucleus.
Since there are 30 protons, the magnitude of charge of the nucleus is expected to be + 30.

You need to determine the
volume piece of chalk using water
displacement. The graduated cylinder
filled with water measures 8.7 mL
before the chalk is added. After the
chalk is added the water level rises
and now reads 12.4 mL. Determine the
volume of the piece of chalk in mL.
Answer:
3.7 mL
Explanation:
Step 1: Given data
Volume of water before the chalk is added: 8.7 mL
Volume of water after the chalk is added: 12.4 mL
Volume of the chalk: ?
Step 2: Calculate the volume of the chalk
The volume of the chalk is equal to the volume of water after the chalk is added minus the volume of water before the chalk is added.
V = 12.4 mL - 8.7 mL = 3.7 mL
Where are each part of the atoms located?
Answer: With the portion of hydrogen, all atoms have three parts. The parts of an atom are protons, electrons, and neutrons. A proton is accurately charged and is located in the center or nucleus of the atom. Electrons are negatively charged and are located in rings or orbits spinning around the nucleus.

Hello I passed my Chemistry exam (Acellus) in the beginning of June:)
Explanation:
1. A student measures the height of a small lamp to be 32cm. According to the factory specifications,
the lamp is actually 30cm. What is the percent error of the student's measurement?
Answer:
6.67 %
Explanation:
Given that,
Measured height of a small lamp, l = 32 cm
Actual height, l' = 30 cm
We need to find the percent error of the student's measurement. Percent error is given by :
[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]
Putting all the values, we get :
[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]
So, the percent error of the student's measurement is 6.67 %.

Explain why energy sources do not have 100% efficiency. Why do you think some have lower efficiencies?
Answer:
Energy sources do not have 100% efficiency because the processes of energy conversion to usable forms involves energy losses.
Some have lower efficiencies due to; energy losses in form of heat during conversion, poor technology applied during conversion of energy and lack of desire equipment to use in the energy conversion system.
Explanation:
The desired form of energy for use is derived from conversion of energy from the source using an energy converter into another form which is usable. The efficiency of the energy converter is calculated as;
л = output energy/input energy
The efficiency of energy is limited to the cost of equipment required for conversion from energy source by the energy converter to a form which is usable. Additionally, because energy sources are scarce, the technology to use in energy conversion is a factor affecting energy efficiency in that high efficiency will require advanced technology with better equipment leading higher costs of that energy form. when heat losses are involved during energy conversion, efficiency lowers, thus its better if such losses are used as energy input in another system.

What happens to the density of a substance when it is heated? Explain your answer.
Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.
