an object has a mass of 57.6g . find the object's density, given that's it's volume is 40.25cm^3
Answer:
The answer is 1.43 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 57.6 g
volume = 40.25 cm³
We have
[tex]density = \frac{57.6}{40.25} \\ = 1.431055900...[/tex]
We have the final answer as
1.43 g/mLHope this helps you
what are the stages of breast cancer and what happens in each stage?
actually anatomy & physiology
own words pls i need it now
Answer:
There are 5 stages of breast cancer: stage 0 (zero), which is non-invasive ductal carcinoma in situ (DCIS), and stages I through IV (1 through 4), which are used for invasive breast cancer. The stage provides a common way of describing the cancer, so doctors can work together to plan the best treatments.

An atom of an element contains 6 protons, 6 neutrons, and 6 electrons. An atom that is a different isotope of this element would contain —
A.
6 protons, 7 neutrons, and 6 electrons.
B.
6 protons, 6 neutrons, and 7 electrons.
C.
7 protons, 6 neutrons, and 6 electrons.
D.
7 protons, 7 neutrons, and 7 electrons.
Answer:
A
Explanation:
An atom that is a different isotope of a given element would contain 6 protons, 7 neutrons, and 6 electrons. Therefore, option (A) is correct.
What is an isotope?Isotopes are atoms of an element that contain the same atomic number as the original element but a different atomic mass. Isotopes of an element possess the same number of electrons and the number of protons but different numbers of neutrons in their respective nucleus.
For example, the isotopes of carbon are carbon-14, carbon-13, and carbon-12. Carbon-14 has a total of 8 neutrons, carbon-13 have a total of 7 neutrons, and carbon-12 has a total of 6 neutrons. So all the isotopes of carbon have different numbers of neutrons.
Given element has 6 protons, 6 neutrons, and 6 electrons. So the isotope of this element will have 6 protons, and 6 electrons but not 6 neutrons. Therefore, the element with 6 protons, 7 neutrons, and 6 electrons is the isotope of the given element.

In the first propagation step of the bromination of 2,3-dimethylbutane, the newly formed Br radicals react with the molecules of 2,3-dimethylbutane. Give the major products formed by the first propagation step including both organic and inorganic products. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.
Answer:
See explanation
Explanation:
When the bromine free radical attacks 2,3-dimethylbutane, two free radicals may result. One of them is primary (formed by attack on then end -CH3 group) the other is secondary.
Recall that the order of stability of free radicals is tertiary > secondary > primary > methyl.
Hence the secondary free radical is more thermodynamically stable hence it is the major free radical formed in the first propagation step.

Potential energy is based on an objects
A)gravity
B)mass
C)position
D)kinetic
Answer:
c
Explanation:
because potential energy is created with the position of a body when you pick up something the thing will have stored energy which is transferred from you so the stored energy is potential energy created by the position of a body that when you see over your head you scared of that thing not to bit you because it has stored energy if you see the thing already failed on the ground you wouldn't scared of that because the enery is already gone

what role do particles play in exterting pressure?
Answer:
Pressure is an important physical quantity—it plays an essential role in topics ranging from thermodynamics to solid and fluid mechanics. As a scalar physical quantity (having magnitude but no direction), pressure is defined as the force per unit area applied perpendicular to the surface to which it is applied. Pressure can be expressed in a number of units depending on the context of use.
Explanation:
Probably not the best answer but hope this helps somewhat. :)

Please help lots of points!!! Net ionic equation for aqueous solutions of perchloric acid and barium hydroxide.
Answer:
H⁺(aq) + OH⁻(aq) = H₂O(l)
Explanation:
To find the net ionic equation start by finding the balanced equation.
2HClO₄(aq) + Ba(OH)₂(aq) ⇒ 2H₂O(l) + Ba(ClO₄)₂(aq)
Then put it into the ionic equation.
2H⁺(aq) + 2ClO₄(aq) + Ba²⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l) + Ba²⁺(aq) + 2ClO₄(aq)
Remove all the ions that do not change.
2H⁺(aq) + 2OH⁻(aq) ⇒ 2H₂O(l)
And reduce to the lowest common coefficient.
H⁺(aq) + OH⁻(aq) = H₂O(l)
Which of the following types of soil has the greatest permeability?
A. Loam
B. Sandy
C. Clay
D. Silty
Answer:
Sandy soil
Explanation:
Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.
Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.
Sandy soils are usually made up of particles with sand-sized shapes and dimension. They have bigger and finer grains with little to no cement. This allows for a high level of permeability with no impediment to flow.Clay soil has very fine grain and with very low permeability. Silty soils have fair enough permeability and the permeability of loam straddles between that of sand and clay.Permeability is very important for determining the quality of soils.
How do you make an atom of F become Ne?

If this decay has a half life of 2.60 years, what mass of 72.5 g of sodium 22 will remain after 15.6 years
Sodium-22 remain : 1.13 g
Further explanationThe atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually, radioactive elements have an unstable atomic nucleus.
General formulas used in decay:
[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]
T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
half-life = t 1/2=2.6 years
T=15.6 years
No=72.5 g
[tex]\tt Nt=72.5.\dfrac{1}{2}^{15.6/2.6}\\\\Nt=72.5.\dfrac{1}{2}^6\\\\Nt=1.13~g[/tex]
