Answer:
0.5 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{5}{10} = \frac{1}{2} = 0.5 \\ [/tex]
We have the final answer as
0.5 m/s²Hope this helps you

For the reaction, calculate how many moles of the product form when 0.046 mol of O2 completely reacts.
Assume that there is more than enough of the other reactant.
2Ca(s)+O2(g)→2CaO(s)
Express your answer using two significant figures.
Answer: 0.023 moles of CaO.
Explanation:
The balanced equation tells us that we'll get 2 moles of CaO for every one mole of O2. Since we have 0.046 moles of O2, we'll get 0.023 moles of CaO. (2 sig figs)

How many milliliters of a stock solution of 12.1 M HNO3 would be needed to prepare 0.500 L of 0.500 M HNO3
Answer:
(5.00M)(X) = (0.120L)(0.470M)
X = (0.120)(0.470)/(5.00)
0.01128
Explanation:
12.1 M HNO3 would be needed to prepare 0.500 L of 0.500 M HNO3 stock solution is 0.01128 milliliters.
What is stock solution ?
The ideal way to define stock solutions is as concentrated solutions with precise, known concentrations that will be diluted for later laboratory usage. Even though you may decide against making stock solutions, doing so may help you run your business more efficiently and save you a ton of time and money.
where C1 x V1 = C2 x V2. Stock concentration, C1 ( beginning concentration ) V1 is the amount of stock needed to make the new solution. C2 is the concentration of a fresh or effective solution.
( 5.00M ) ( X ) = ( 0.120 liter ) ( 0.470 M )
Then, X = 0.120 × 0.470 ÷ 5.00
= 0.01128 milliliters.
Thus, 12.1 M HNO3 would be needed to prepare 0.500 L of 0.500 M HNO3 stock solution is 0.01128 milliliters.

Violet light has a wavelength from 380 nm to 420 nm.
What velocity must a free electron have in order to exhibit the same wavelength as a violet photon with a
wavelength of 415 nm?
This question involves the concepts of de Broglie's wavelength and momentum.
The velocity of the electron must be "1754.27 m/s".
de Broglie's wavelength is a wavelength associated with a moving matter particle. It is connected to the momentum of the particle by the following formula:
[tex]P =\frac{h}{\lambda}\\\\mv=\frac{h}{\lambda}\\\\v=\frac{h}{m\lambda}\\\\[/tex]
where,
v = velocity of electron = ?
h = Plamk's Constant = 6.625 x 10⁻³⁴ J.s
m = mass of electron = 9.1 x 10⁻³¹ kg
λ = de Broglie's wavelength = 415 nm = 4.15 x 10⁻⁷ m
Therefrore,
[tex]v=\frac{6.625\ x\ 10^{-34}\ J.s}{(9.1\ x\ 10^{-31}\ kg)(4.15\ x\ 10^{-7}\ m)}[/tex]

Atoms are the smallest particle that make up living things, they are made up of subatomic particles; protons, neutrons and electrons. Of these the electrons and neutrons are in the nucleus and the protons orbit around the nucleus. Of the subatomic particles, the electrons have the largest mass and are negatively charged, the neutrons (negative charge) and protons (positively charged) both have a relative mass of 1. Atoms contain an equal number of protons and neutrons, so carry no overall charge. An element is a substance made up of only two types of atom. Elements can be found in the Periodic table of elements, they usually have two numbers next to the chemical symbol, the larger number is generally the atomic number, which represents the number of neutrons and the number of protons. The smaller number is the relative atomic mass which represents the number of electrons or neutrons. In order to calculate the number of neutrons, you minus the atomic number from the relative atomic mass.

Which class of macromolecule was described as being most like the hydrocarbons?.
Answer:
Fats........................
Lipids is the class of macromolecule was described as being most like the hydrocarbons.
what are Macromolecules ?Macromolecules are bigger molecules of large size and made of smaller molecules called as monomers, Polymers are macromolecules.
All Macromolecules are not like the hydrocarbon because the macromolecules not only consists of C and H atoms but also N and O.
Macromolecules are classified into 4 types
Proteins , Carbohydrates , Lipids and Nucleic Acids
Lipids is the class of macromolecule was described as being most like the hydrocarbons.
Lipids are a broad category of chemicals that are mostly nonpolar in nature.
This is due to the fact that they are hydrocarbons with nonpolar carbon–carbon or carbon–hydrogen bonds.

how many repeat units are required to make a nylon polymer with a formula weight of 15,000 amu?
This problem is giving information about a nylon polymer whose molar mass is 15,000 amu (atomic mass units).
The first subject of matter here, is to recall the monomeric molecular formula of nylon which is C₁₂H₂₂N₂O₂, and the definition of monomer (basic molecule able to react and form a polymer) and polymer (assembling of monomers).
Next, we calculate the molar mass of the monomer of nylon:
[tex]12*12.01+22*1.01+2*14.01+2*16.00=226.31amu[/tex]
Finally, the number of units is calculated by dividing the molar mass of the polymer and the monomers:

According to coulomb's law, in which ionic compound are the attractive forces the strongest?.
Answer:
A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.
which value represents the first ionization energy of a nonmetal
Answer:
increase in going from left to right across a given period.
Explanation:
Nonmetals, which are found in the right-hand region of the periodic table, have relatively large ionization energies and therefore tend to gain electrons. Ionization energies generally increase in going from left to right across a given period.

Which image represents a homogeneous mixture?
Which image represents a heterogeneous mixture?
Imagine A represents a heterogeneous mixture as it is a mixture composition that does not remain the same throughout the mixture whereas Imagine B represents a homogeneous mixture as it does not have any change or irregularity.
What are Homogenous and Heterogenous mixtures?A homogeneous mixture is defined as having a fairly uniform form and composition, so many homogeneous mixtures are referred to as solutions whereas heterogeneous mixtures are defined as separate substances or phases. The three states or states of matter are gas, liquid and solid.
Some examples of mixtures that include mixtures of sand and water, mixtures of sugar and salt, and mixtures of lime juice and water.
In homogenous solution, particles are distributed uniformly and have uniform composition while in heterogenous solution, particles are distributed non-uniformly and have non-uniform composition

What is the molarity of an ethanol solution containing 10.0g of ethanol in
water with a total volume of 100ml?
Answer:
2.17 moldm-3
Explanation:
Molarity is the number of moles of solute in a unit volume.
The atomic masses of
C -12
H-1
O-16
Therefore molar mass ( mass of 1 mol ) of ethanol ( CH3CH2OH )
( 12 x 2 ) + (1 x 6) + 16 = 46 g/mol
In 10 g of ethanol 10/46 mol should be present
So the molarity is (10/46) mol ÷ 100ml
= 10/ 46 mol ÷ 0.1 l
1L = 1 dm3
Therefore molarity = 10/46 mol ÷ 0.1 dm3
= 2.17 mol/dm3
