5. What is the charge on a single proton?
Answer:
it may be +1 or -1 hope this help
An atom is a kind of stuff that cannot be further decomposed chemically. Therefore, the charge on a single proton is +1.
What is atom?
The building block of an element is an atom. An atom is a kind of stuff that cannot be further decomposed chemically. The three main components of an atom are protons, neutrons, plus electrons.
Some substances are either bigger or smaller than atoms. Instances of chemical species that aren't commonly regarded as atoms include protons, neutrons, and electrons, which are atom-related particles. Atoms make up molecules and compounds, however they are not actual atoms. Salt is an example of a molecule and a compound (NaCl). The charge on a single proton is +1.
Therefore, the charge on a single proton is +1.

Which of the following diagrams represents a single
replacement reaction?
Explanation:
i think the answer is....b
The diagram that represents single replacement reaction is:
b.
Single replacement reaction:This reaction is also known as displacement reaction. It is a reaction in which one element is substituted for another element in a compound. When a replacement reaction occurs, a new aqueous compound and a different pure element will be generated as products. For example:
[tex]2HCl(aq)+Zn(s)--->ZnCl_2(aq)+H_2(g)[/tex]
Thus, option b is correct.

How much does a 130 kg object weigh on Earth?
A 130 kg object weighs approximately, 1274 Newtons on Earth.
The weight of an object on Earth can be calculated using the formula:
Weight = mass × acceleration due to gravity
Weight is calculated by multiplying the mass of an object by the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (9.8 m/s²).
In this case, we have a 130 kg object. To find its weight on Earth, we can use the formula:
Weight = mass × acceleration due to gravity
Weight = 130 kg × 9.8 m/s²
Weight = 1274 Newtons (N)
So, the weight of a 130 kg object on Earth is approximately 1274 Newtons.
Therefore, a 130 kg object weighs approximately, 1274 Newtons on Earth.

Actually Welcome to the Concept of the Lens and Ray Optics.
We must understand the Concept that,
1.) When a beam of parallel light pass through a Convex lens, all the rays get deviated and converges to a special point at the axis that is a Focus.
2.) When a beam of light passes through the Concave lens,the light beams diverge from one another forming a virtual focus in the primary side of lens,
Hence the above given diagram beam rays are diverging, it is a CONCAVE LENS
answer is C.) Concave lens

if a sample of 4.50 moles of hydrogen gas was reacted with excess nitrogen, how many moles of ammonia gas would be produced?
Answer: 3.00
Explanation: got the answer from my teachers notes
According to stoichiometry, if a sample of 4.50 moles of hydrogen gas was reacted with excess nitrogen, 3 moles of ammonia gas would be produced.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is useful in balancing chemical reactions.In the given reaction 3 moles hydrogen gives 2 moles ammonia, thus, 4.5 moles of hydrogen will give, 4.5×2/3=3 moles.
Thus, if a sample of 4.50 moles of hydrogen gas was reacted with excess nitrogen, 3 moles of ammonia gas would be produced.

what's the difference between viscosity and flow rate
Answer:
Flow rate is how fast a fluid moves. The flow rate can depend on several factors. These factors are the type of fluid that you are using, the force that is pushing on a fluid, the size of the pipe the fluid flows from and the type of surface the fluid flows over. Viscosity is the resistance of a fluid to flow.

what is the molarity of 5.63 moles of lithium in 3.25 liters of solution
Answer:
1.73 Molar
Explanation:
The formula is Molarity=moles of solute/liters of solution, which can be written in whatever way you prefer, and examples include: M=N/V or M=mol/L.
M=N/V
M= [tex]\frac{5.63}{3.25}[/tex]
Divide 5.63 by 3.25. When you calculate this, you get 1.73, therefore your answer is 1.73 molar.

Which of the following choices shows the correct Lewis electron-dot diagram for a molecule of chlorine, Cl2?
Answer: 2!
Explanation:
The best lewis structure for [tex]Cl_2[/tex] is in option 2.
Na or sodium is the cation in the reactant.
Cl or chlorine is the anion in the reactant side.
NaCl is the product of the reaction.
Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.
Chlorine is a group VIIA element in the periodic table and contains seven electrons in its last shell.
Valence electrons are given by chlorine atoms = [tex]7\times2=14[/tex]
Total valence electrons = 14
So, each of Cl is surrounded by three pairs of dots, connected by a single line. So, the best lewis structure for [tex]Cl_2[/tex] is in option 2.
