Explanation:
A homogeneous mixture can be described as the solute uniformly dissolving in a solvent to make a solution. Therefore, option (B) is correct.
What is a homogeneous mixture?A mixture can be described as a combination of two or more substances that are not chemically combined with each other. Mixtures can be categorized into two kinds homogeneous mixtures and heterogeneous mixtures.
A homogeneous mixture can be defined as one whose whole composition is uniform throughout the entire mixture. It can be the type of mixture where the entire composition is constant throughout that make up the mixture and is distributed uniformly.
A homogeneous mixture can be described as a gaseous, liquid, or solid mixture that has equal proportions of its components throughout the sample. In a homogeneous mixture, there is only one phase of matter observed.
Some examples of Homogeneous Mixtures are Air Rainwater, Vinegar, Dishwashing detergent, Steel, Sugar water, a Cup of Coffee, etc.

A sample of an element has a mass of 80.01g and a density of 2.70 g/cm3. How many significant figures does the mass have?
The mass has 4 significant figures
Further explanationRules for significant numbers
1. all non-zero numbers are significant numbers 2. a zero which is located between two non-zero numbers including a significant number 3. all zeros are located in the final row written behind the decimal point include significant number 4. zero decimal point is not significant numbera sample has mass = 80.01 g
a zero which is located between two non-zero numbers including a significant number, so the mass has 4 significant figures : 8,0,0 and 1

Show with dot and cross diagram of the formation of ions in the reaction of Fluorine with sodium ions.
Answer:
Please check the attached file
Explanation:
Sodium is present in group one. It has one valence electron. It is alkali metal. All alkali metal form salt when react with halogens.
Sodium need to lose one electron to get stable. All halogens have seven valence electrons they need only one electron to get stable electronic configuration.
When alkali metals such as sodium react with halogen fluorine it loses its one valence electron which is accepted by fluorine and ionic bond is formed. The compound formed is called sodium fluoride.
In cross and dot diagram electrons of one atom are shown as dots while other atom shown as cross to distinguish.
Please check attached file for electron dot diagram.

There are 55.0 g of neon gas in a 3.0 L cylinder, the pressure is 4.5 atm what is the temp of the gas
Answer:
60.9 Kelvin
Explanation: First, write out everything that you know. You are tring to find the temperature, so the temperature will be represented by x.
Pressure (P)= 4.5 atm
Volume (V)= 3L
Number of Moles (n)= ?
Gas Consant (R)= 0.0821, if the pressure is in atm, that means r is 0.0821
Temperature (T)= x
We don't have all the information we need to plug the values into the equation. We still need to know how many moles 55.0 grans of neon is.
Ne in Grams= 55
Atomic Mass of Ne= 20.1797
55/20.1797= 2.7
moles= 2.7
Now that we have all the information we need, plug everying into the equation. In case you don't know, the Ideal Gas Law Equation is PV= nRT.
(4.5)(3) = (2.7)(0.821)x
x= 60.9
Now you have your temperature! It is 60.9 in Kelvin.
Which describes 5 molecules of water?
1. 2 H2O
2. H2O3
3. 5 H2O
5 molecules of water is 5 H2O.
One water , H2O. molecule consist of one oxygen atom bonded with two atoms of hydrogen. The structure of water molecule is bent. Water is a polar compound. Oxygen is more electronegative than the hydrogen atom. The oxygen atom get partial negative charge and the hydrogen atoms get partial positive charge. Water is a universal solvent. The hydrogen and oxygen atoms are held together by a covalent bond . covalent bond is formed by the sharing of electrons between the two atoms. water The chemical name of water is Dihydrogen monoxide.
Thus, 5 molecules of water is 5 H2O.

O2 are mixed together, and the above reaction goes to completion?
08.00
10.0
04.00
20.0
Lo
Answer:
4.00 moles of water
Explanation:
The equation of the reaction is:
2 C2H2Cl (9) + 5O2(g) -------> 4CO2 (g) + 2 H20( g) + 2 HCl(g)
To find the limiting reactant, we find the species that yields the lowest number of moles of water.
From the reaction equation;
2 moles of C2H2Cl yields 2 moles of water
10 moles of C2H2Cl yields 10 * 2/2 = 10 moles of water
Similarly;
5 moles of oxygen yields 2 moles of water
10 moles of oxygen will yield 10 *2/5 =4 moles of water
Hence oxygen is the limiting reactant.
10 moles of oxygen yields 4 moles of water.

The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

Answer:
Explanation:
In this case, the fitness magazine compared the food we eat with a battery because the food provides energy for the human body to perform its daily activities.
The banana is an excellent source of energy, as it is a fruit with a high content of carbohydrates and fructose, it is an excellent food to be eaten before physical exercise, as it provides the muscles with enough energy to increase performance before and after exercise. , is a fruit rich in potassium, magnesium, phosphorus, and vitamins a and c, which gives greater strength and energy.
