A nucleus of uranium 235 decays. Its decay produces a nucleus of an unknown element (x), a nucleus of helium 4 and energy. What kind of radiation is produced by this decay?
Gamma beta or alpha?
Answer: Alpha
Explanation:
Alpha particle form of decay produces a nucleus similar to the element helium. During Alpha decay an atom spits out two protons and two neutrons from its nucleus.
Si 4 L de un gas están a 0,79 atm de presión, ¿Cuál será su nuevo volumen, si aumentamos la presión hasta 1,05 atm?
Respuesta:
3 L
Explicación:
Paso 1: Información provista
Volumen inicial del gas (V₁): 4 LPresión inicial del gas (P₁): 0,79 atmVolumen final del gas (V₂): ?Presión final del gas (P₂): 1,05 atmPaso 2: Calcular el volumen final del gas
Si suponemos que el gas se comporta como un gas ideal y que la temperatura permanece constante, podemos calcular el volumen final del gas usando la ley de Boyle.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0,79 atm × 4 L / 1,05 atm = 3 L

Answer:
1. Acids
2. Its molecular arrangement
3. Very acidic
4. Unsaturated
5. Apple juice
Explanation:
1. Acids have pH less than 7
2. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.3. Very acidic
4. Unsaturated solutions are solutions in which the amount of dissolved solute is less than the saturation point of the solvent (at that specific temperature gradient).
5. The lower the pH, the more hydrogen molecules.

1) How many mL of 5.00M CaSO4 solution must be
diluted with water to prepare 500.0 mL of 0.900M CaSO4?
2) 20.0 mL of a stock solution of NaOH is diluted with water to prepare 150.0mL of 1.50 M NaOH solution.
Calculate the Molarity of the stock NaOH solution?
3) 12.00 mL of 3.50 M NaOH solution is diluted with 88.0 mL of water.
What is the concentration of sodium hydroxide in the diluted solution?
4) 9.0 mL of 8.0 M HCl solution is diluted with water to prepare 0.50 M HCl solution. What is the final volume of this solution?
All questions can be solved by C1V1=C2V2
1) 5.00M x V1 = 0.900M x 500.0 mL
V1= 90 ml
therefor you need to add 500 - 90 = 410.0 ml
2) 20.0 mL x C1 = 150.0mL x 1.50 M
C1= 11.25 M
3) 12.00 mL x 3.50 M = 100.0 mL x C2
C2= 0.42 M
4) 9.0 mL x 8.0 M = 0.50 M x V2
V2 = 144 ml

Which substance is a type of biomolecule that can be used for energy storage and insulation? O A. Nucleic acid O B. Carbon dioxide O C. Lipid D. Protein
Answer:
Protein
Explanation:
Protein is used to make insulation (like fat) and is used to store energy taken form food (please tell me if this works)
Protein which is made up of amino acids is a type of biomolecule that can be used for energy storage and insulation.
What are amino acids?Amino acids are defined as the substances which are considered to be the monomers of proteins.Every amino acid has the same structure consisting of a central carbon which is bonded to an amino group , carboxyl group and a hydrogen.
Each amino acid also has another atom or a group of atoms bonded to the alpha carbon which are also known as the R group or the variable group of the side chain.There are 20 common amino acids present in natural proteins and each amino acid has the same backbone.
The sequence and number of amino acids determines protein's shape,size and also its function. Each amino acid is attached to the other by a covalent bond formed by a dehydration reaction.

Se disuelven 10 g de acido carbónico H2CO3 en 150 g de agua. Determina la concentración % m/m de esa disolución?
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100[/tex]
Substitute the values into above formula as follows.
[tex]Percent (m/m) = \frac{mass of solute}{mass of solvent} \times 100\\= \frac{10 g}{150 g} \times 100\\= 6.66%[/tex]
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
explain why the sun's light seems to be all around us instead of focused like a spotlight on the earth.
Answer:
Hmmm
Explanation:
To be honest this seems to be a straight forward question but it's not at the same time. I mean obviously the sun is in the center and we just surround it. So it's light kinda just hits the whole Earth. In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
CH4 + 2O2=CO2+2H2O. how many moles of O2 will be needed to produce 5.0 moles of CO2 from the correctly balanced reaction?
Answer:
10 moles of O2
Explanation:
Balanced Equation:
CH4 + 2O2=CO2+2H2O
Now,
According to Stoichiometry,
In the reaction,
1 mole CO2 is produced by 2 moles of O2
∴5 moles of CO2 is produced by (2 X 5) moles of O2
= 10 moles of O2
Therefore, to produce 5 moles of CO2, 10 moles of Oxygen is needed.
