The relationship among force, mass, and acceleration is force equals mass times acceleration. Therefore, option B is correct.
What is an acceleration ?The term acceleration is defined as the rate of change of velocity. When an object moves in a circular path at a constant speed, it is still accelerating because its velocity direction changes.
The application of a net force to an object alters its motion, the greater the net force, the greater the acceleration. More massive objects necessitate greater net forces to accelerate at the same rate as less massive objects.
“Force equals mass times acceleration.” This is because this shows the equation for force, and thus it shows the relationship between them in how they are used.
Thus, option B is correct.

The atomic number of an element gives several pieces of information including:Choose all that apply [] the elements color [] the number of protons [] the number of electrons [] the elements position on the periodic table
Atomic numbers are the numbers possessed by an element in a periodic table. These numbers are used to identify an element and their position in the periodic table.
The atomic number of an element is equal to its proton and electron number but not its neutron
Hence we can conclude that the correct information about the atomic number of an element includes:
• The number of protons
• The element position on the periodic table
High temperatures can lead to the melting of metamorphic rock and the formation of _____.
The metamorphic rock on high temperatures could melt and result in the formation of Igneous rock
New rock formation happens when there is an increase in temperature or pressure or in some cases both.
On either high temperature or high pressure, the metamorphic rock would melt. The melting of metamorphic rock would result in magma. This magma on cooling solidifies and forms Igneous rock. It is crystalline/glassy in nature.
On the other hand, if igneous rock melts under high pressure or temperature, it would revert back to metamorphic rock.

Determine the quantity in moles of RbF that are in 57.0 grams of RbF.
The quantity of moles in 57.0grams of RbF is 0.545mol.
How to calculate number of moles?Moles is the base unit of amount of substance i.e. the amount of substance of a system which contains exactly 6.022 × 10²³ elementary entities (atoms, ions, molecules, etc.).
The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.
No of moles = mass ÷ molar mass
Molar mass of RbF = 85.467 + 18.998 = 104.5g/mol
moles = 57.0g ÷ 104.5g/mol = 0.545mol
Therefore, 0.545moles is the quantity of moles of RbF in 57.0grams of the compound.

When a solute dissolves in water, a solution is formed.
What is a solute?A solute is any substance capable of dissolving in a solvent in order to form a solution.
When a solute dissolves in a particular solvent, it is said to be that solvent-soluble. Otherwise, it is insoluble.
Now, when the solvent in question is water, the substance is said to be water-soluble or water-insoluble as the case may be.
If a solute is water-soluble, then it forms a solution. If the solute is ionic, it does not just form a solution, it dissociates into its component ions in the solution.

how many grams of silver iodide, AgI, are produced from 43.3 g of calcium iodide, CaI2?
Taking into account the reaction stoichiometry, 121.89 grams of AgI are produced from 43.3 g of calcium iodide.
Reaction stoichiometryIn first place, the balanced reaction is:
CaI₂ + 2 AgNO₃ → 2 AgI + Ca(NO₃)₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
CaI₂: 1 moleAgNO₃: 2 molesAgI: 2 molesCa(NO₃)₂: 1 moleThe molar mass of the compounds is:
CaI₂: 166.9 g/moleAgNO₃: 169.87 g/moleAgI: 234.77 g/moleCa(NO₃)₂: 164 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
CaI₂: 1 mole ×166.9 g/mole= 166.8 gramsAgNO₃: 2 moles ×169.87 g/mole= 339.74 gramsAgI: 2 moles ×234.77 g/mole= 469.54 gramsCa(NO₃)₂: 1 mole ×164 g/mole= 164 gramsMass of AgI formedThe following rule of three can be applied: if by reaction stoichiometry 166.8 grams of CaI₂ form 469.54 grams of AgI, 43.3 grams of CaI₂ form how much mass of AgI?
mass of AgI= (43.3 grams of CaI₂×469.54 grams of AgI)÷ 166.8 grams of CaI₂
mass of AgI= 121.89 grams

According to the given statement the molar mass of the gas is 39.400 g/mole.
How is the molar mass calculated?The mass in grams of one mole of a substance is its molar mass. The molar mass of a substance can be determined by adding the molar masses of its component atoms, as shown in this video. The computed molar mass can then be used to convert the mass and the number of molecules of the substance..
Briefing:From ideal gas equation we know, PV = nRT
PV =w/M * RT
n is number of moles = w/M,
we = weight of gas,
M = molecular weight of the gas
PV = wRT/M
Value of pressure, P = 1atm and standard temperature, T = 298.15K
Value of universal gas constant,
R = 0.082 lit. atm. K⁻¹.mol⁻¹
Weight of gas,
w = 0.8058g and volume of gas,
V = 500mL = 0.5 Liters

From the particles shown, the ones that will have a stronger attraction to each other are those in water H₂O. This is because water has a boiling point of 100°C while that of CO₂ is -78.5. Hence, while both are covalently bonded, the bonds in water are stronger.
What is a Covalent Bond?It is to be noted that a covalent bond is formed between two atoms by the mutual use of one or more pairs of electrons. The two atomic nuclei attract these electrons at the same time. When the difference in electronegativities of two atoms is too tiny for electron transfer to produce ions, a covalent bond occurs.
The word "covalent bond" first appeared in 1939. The prefix co- denotes jointly, related in action, paired to a lesser degree, etc.; hence, a "co-valent bond" in essence indicates that the atoms share "valence," as defined in valence bond theory.
