What element is 1s^2 2s^2 2p^6 3s2 3p^3
Answer:
Phosphorus
Explanation:
If you add up all the electrons (the exponents) it equals 15 which is the atomic number of phosphorus. And since stable atoms have the same number of protons and electrons it'll be phosphorus

Where in nature would we find pure
sand that does not contain smaller or
larger particles?
Explanation:
Sand is a common material found on beaches, deserts, stream banks, and other landscapes worldwide. In the mind of most people, sand is a white or tan, fine-grained, granular material. However, sand is much more diverse - even beyond the pink sand beaches of Bermuda or the black sand beaches of Hawaii.
Elements in Group I of the Periodic Table react with water.

Answer:
B
Explanation:
In a garage there are two freezers. One freezer is kept at -30 degrees Celsius. The other
freezer is kept at 0 degrees Celsius. Water is put into both of the freezers. After several
days have passed,
which of the following statements is true?
O The ice at 0 degrees is warmer than the ice at -30 degrees.
O The water has turned to ice in both freezers and the ice is the same temperature
All the water has turned to ice in the one freezer but is still all water in the other freezer
Neither freezer has turned the water into ice
Answer:
Number 1
Explanation:
O The ice at 0 degrees is warmer than the ice at -30 degrees.
What term is used by chemists to quantitatively describe a solution in which a relatively small amount of solute is dissolved?
Si en un planeta la presión atmosférica es mayor que 5,1 atm terrestres, los habitantes podrían nadar en ríos de dióxido de carbono líquido?
Answer:
Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido
Explanation:
De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.
Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.
A hot, gas-like mixture with no definite volume or shape that is made up of electrically charged particles is _________. * 1 point
Answer:
Plasma
Explanation:
In addition to solid, liquid and gas, there exists a fourth state of matter called the plasma.
Plasma is a state of matter involving super=heated matter such that electrons leave atoms thereby leading to the formation of an ionized gas.
In summary, plasma is a hot, gas-like mixture with no definite volume or shape that is made up of electrically charged particles.

Answer:
Organelles, prokaryotic, organelles, cytoplasm, prokaryotic, nucleus
Explanation:
Organelles are membrane bound only in eukaryotic ccells.
Prokaryotic cells unlike eukaryotic cells, do not have membrane bound organlles.
Something that is found in both prokaryotic and eukaryotic cells is the cytoplasm, which is fluid that is inside the whole cell.
Unlike eukaryotic cells, prokaryotic cells have loose DNA, which floats around the cell quite literally.
The only way DNA is stored in eukaroyotic cells is in the nucelus, which is only found in eukaryotic cells, not prokaryotic.

What is the pH of a solution with a [H+] concentration of 1.0 x 10^-6 M?
Answer:
6Explanation:
The pH of a solution can be found by using the formula
[tex]pH = - log ([ {H}^{+} ])[/tex]
From the question we have
[tex]pH = - log(1.0 \times {10}^{ - 6} ) \\ = 6[/tex]
We have the final answer as

Cuántos mililitros de agua hay en 3 litros de una botella de naranjas y las solucion tiene una concentracion de 20% v/v
Respuesta:
2400 mL
Explicación:
Paso 1: Información dada
Volumen de solución: 3 L (3000 mL)Concentración de naranja: 20 % v/vPaso 2: Calcular el volumen de naranja
La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.
3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja
Paso 3: Calcular el volumn de agua
El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.
VSolución = VNaranja + VAgua
VAgua = VSolución - VNaranja
VAgua = 3000 mL - 600 mL = 2400 mL
Determine the concentration of strontium ions in saturated solution of strontium sulfate, SrSO4, if the Ksp for SrSO4 is 3.2x10-7.
Answer:
[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]
Explanation:
Hello there!
In this case, given the solubility equilibrium of strontium sulfate:
[tex]SrSO_4(s)\rightleftharpoons Sr^{2+}(aq)+SO_4^{2-}(aq)[/tex]
Whose equilibrium expression is:
[tex]Ksp=[Sr^{2+}][SO_4^{2-}][/tex]
In such a way, we can introduce the molar solubility, s, in the equation to obtain:
[tex]Ksp=s*s=s^2\\\\3.2x10^{-7}=s^2[/tex]
Then, we apply the square root to obtain:
[tex]s=\sqrt{3.2x10^{-7}}\\\\s=5.66x10^{-4}M[/tex]
Which is also the concentration of strontium ions:
[tex][Sr^{2+}]=5.66x10^{-4}M[/tex]

Why do plants need sunlight for photosynthesis?
Explanation: Plants using photosynthesis will take in carbon dioxide from the air, bring up water from the roots, and use sunlight as the energetic source to create sugar from water and carbon dioxide. Plants contain a molecule called chlorophyll, and the chlorophyll is what absorbs the sunlight
