The function of the mitochondria is to obtain and convert energy. What body system has a similar function?
Explanation:
Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis
equivalent mass of AL2O3
Answers
Answer:
[tex]Mass = 102g[/tex]
Explanation:
Given
Compound: [tex]Al_2O_3[/tex]
Required
Determine the equivalent mass
In the above compound, we have: 2 Al and 3 (O)
The atomic mass of Aluminium is:
[tex]Al = 27[/tex]
The atomic mass of Oxygen is:
[tex](O) = 16[/tex]
So, the equivalent mass is:
[tex]Mass = 2 * 27 + 3 * 16[/tex]
[tex]Mass = 54 + 48[/tex]
[tex]Mass = 102g[/tex]

the half-life of this isotope?
Answers
Answer:
Half life = 7.2 seconds
Explanation:
[tex]from \: decay \: equation \\ 2.303 log( \frac{n.}{nt} ) = kt \\ 2.303 log( \frac{50}{12.5} ) = k \times 14.4 \\ k = \frac{2.303 log( \frac{50}{12.5} )}{14.4} \\ k = 0.096288 {s}^{ - 1} \\ since \: half \: life = \frac{ ln(2) }{k} \\ half \: life = \frac{ ln(2) }{0.096288} \\ half \: life = 7.2 \: seconds[/tex]
That will work with all of those problems
So if it’s is a quarter of an isotope you’d divide by 4

A student spends 4.5 hours studying for a test. How much time is this equivalent to in seconds?
Select one:
a. 2,700 seconds
b. 16,200 seconds
c. 270 seconds
d. 6,480 seconds
Answers
Answer:
B. 16,200
Explanation:
1) Reduce.
4.5 hours can be translated to minutes. We know there are 60 minutes in an hour.
4.5 * 60 = 270 minutes
2) Reduce further
270 minutes can then be translated to seconds using the same equation
270 * 60 = 16,200

This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :

Which of the following is a possible compound formed from Ca2+ and NO3-1?
F Ca2NO3
G Ca(NO3)2
H Ca3NO2
J CaNO
Answers
Answer:
Ca(NO3)2
.................
Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.
Ions, which are charged atoms of elements come together to form ionic compounds. A positively charged ion called cation reacts with a negatively charged ion called anion to form a neutral ionic compound i.e. compound with a charge of 0. In this question, cation Ca²+ reacts with anion NO3-. The ionic compound formed must have a net charge of 0. This can only happen if 2 moles of NO3- and 1 mole of Ca²+ is present in the compound. The resulting ionic compound can be chemically represented as Ca(NO3)2. Therefore, Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.Learn more at: https://brainly.com/question/11148793?referrer=searchResults

Answers
Answer:
2.75 × 10^-45 m
Explanation:
From;
E= hc/wavelength
h= Plank's constant= 6.6 × 10^-34 Js
c= speed of light=3× 10^8 ms-1
Wavelength = 6.6 × 10^-34 × 3× 10^8/7.21 × 10^19

Tanisha is mixing powdered orange drink mix into a cup. She wants to make sure the orange taste is strong, so she adds a lot of powdered mix. As she is mixing, she notices that the powdered mix starts to float around in the water in clumps, and some settles on the bottom of the cup. Predict why this would happen.
A.
The powder is too old to dissolve in the water.
B.
No more powder will dissolve in the water.
C.
The powder needs to be shaken to fully dissolve.
D.
The powder does not fully dissolve because the water is too warm.
Answers
Answer:
B. No more powder will dissolve in the water.
Explanation:
If a lot of powder is added to the water, then a fully saturated solution would be created. This means that no matter how much more powder is added or how strong the mix is shaken, no more powder will disolve. The powder will instead remain in solid form in the solution.
Answer:
Heat up the water first because it increases solubility of the powdered mix.
