Un buzo que nada en las profundidades despide pequeñas burbujas de aire¿Aumenta disminuye o permanece igual el tamaño de las burbujas conforme suben a la superficie?
Answer:
Al ascender las burbujas van aumentando de tamaño.
Explanation:
Las burbujas que produce el buzo debajo del agua son pequeñas moléculas de dióxido de carbono gaseoso producto de la respiración del mismo.
Ahora, a medida que las burbujas suben a la superficie, la presión que sufren estas (Presión debido al agua), es menor conforme van ascendiendo debido a la ley de Boyle: A medida que la presión aumenta, el volumen va disminuyendo.
Esto significa que al ascender las burbujas van aumentando de tamaño debido a que la presión que sufren estas es menor que cuando están a mayores profundidades.

Convert 1.4 x 10-4 cm to decimeters
Answer:
1.4 x 10^-5 dm
Explanation:
Centimeters (cm) and decimeters (dm) are interconvertible S.I units of length.
- A centimeter is one-hundredth of a meter i.e. 100cm = 1m
- A decimeter is one-tenth of a metre i.e. 10dm = 1m
Based on this, a centimeter is one-tenth of a decimeter i.e. 1dm = 10cm
Hence, to convert 1.4 x 10^-4 cm to dm, we divide the value by 10
= 1.4 x 10^-4 ÷ 10
= 0.00014 ÷ 10
= 0.000014
Convert back to scientific notation by counting the decimal point forward to have: 1.4 x 10^-5
Hence, 1.4 x 10^-4 cm is equivalent to 1.4 x 10^-5 dm.
Atoms of two different elements must have different electrical charges. numbers of neutrons. atomic numbers. energy levels.
Answer:
atomic numbers
Explanation:
Atoms are the unit of molecules and compounds or matter. They have their atomic numbers and mass. Atoms of different elements must have different atomic numbers. Thus, option C is correct.
What is an atomic number?An atomic number is the total number of protons in a nucleus that is an essential factor in determining the place and position of the atom in the periodic chart.
Though the nucleus is made of neutrons and protons, the atomic number is only defined by the number of protons alone. Hence, the number of protons is equivalent to the atomic number.
The number of the protons and neutrons together makes the atomic mass of the element that is expressed at the lower of the symbol, whereas the atomic number is written at the upper of the symbol.
Therefore, the atomic number is different in each atom.

Tokyo, Japan is 8817.6 km from California. how many millimeters is this? answer in scientific notation.
Answer:
[tex]d=8.817\times 10^9\ mm[/tex]
Explanation:
It is given that,
Japan is 8817.6 km from California. We need to convert this distance in millimeters.
We know the conversion from km to mm is as follows :
1 km = 1000000
To convert mm km to mm use the unitary method as follows :
8817.6 km = 8817.6 × 1000000
[tex]d=8.817\times 10^9\ mm[/tex]

6 A student has a mass of 6.35 x 10^1 kg. What number below is the
equivalent to the student's mass? *
O A. 6.35 x 10^-2 g
B. 6.35 x 10^4 g
O C.635 g
O D. 215 lb.
Answer:
B. 6.35 x 10^4 g
Explanation:
Quantities such as mass have more than units that are interconvertible. Mass can be measured in kilograms (kg), grams (g), etc.
However, 1kg equals 1000grams
Hence, a measurement of 6.35 x 10^1 kg will be equivalent to grams (g) by multiplying by 1000units
That is, 6.35 × 10^1 × 1000
= 6.35 × 10^1 × 10^3
Multiplication in index means to add the powers
= 6.35 × 10^ (1+3)
= 6.35 × 10^4grams
Therefore, an equivalent measurement of 6.35×10^1 kg is 6.35×10^4 g.

Net ionic equation
Answer :
The complete balanced equation will be,[tex]Al(OH)_3(aq)+K_3PO_3(aq)\rightarrow AlPO_3(s)+3KOH(aq)[/tex]
The complete ionic equation in separated aqueous solution will be,[tex]Al^{3+}(aq)+3OH^{-}(aq)+3K^{+}(aq)+PO_3^{3-}(aq)\rightarrow AlPO_3(s)+2K^+(aq)+3OH^{-}(aq)[/tex]
The net ionic equation will be,[tex]Al^{3+}(aq)+PO_3^{3-}(aq)\rightarrow AlPO_3(s)[/tex]
Explanation :
In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The complete balanced equation will be,
[tex]Al(OH)_3(aq)+K_3PO_3(aq)\rightarrow AlPO_3(s)+3KOH(aq)[/tex]
The complete ionic equation in separated aqueous solution will be,
[tex]Al^{3+}(aq)+3OH^{-}(aq)+3K^{+}(aq)+PO_3^{3-}(aq)\rightarrow AlPO_3(s)+2K^+(aq)+3OH^{-}(aq)[/tex]
In this equation, [tex]K^+\text{ and }OH^-[/tex] are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
[tex]Al^{3+}(aq)+PO_3^{3-}(aq)\rightarrow AlPO_3(s)[/tex]
