Write a scientific explanation that compares the electrical forces of ethanol, hexane, and water.
Claim:
Evidence:
Reasoning:
Answer:
"Water and ethyl alcohol will both have dipole-dipole interactions.
Technically they will both have Hydrogen bonding, which is a type of dipole-dipole. This is due to the high electronegativity values of oxygen atoms compared to the carbon and hydrogen atoms the oxygens bond to. This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges.
Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces."
Explanation:
Here is the place I found the answer: https://socratic.org/questions/which-of-these-structures-has-dipole-dipole-interactions-water-h2o-ethyl-alcohol

about how many days does it take to go from one moon phase to another
Answer:
After one month, the Moon returns to the same location in the sky as the Sun and we see a New Moon again. The demo represents a month as 28 days for simplicity. But the real cycle of phases takes 29.5 days to complete.

Calculate the molarity of a MgSO4, solution
prepared by adding 0.32 moles of MgSO4, to
enough water to make 5.5 L of solution,
Answer in units of M.
Answer:
0.058M is molarity of the solution
Explanation:
Molarity is defined as the ratio between the moles of solute (In this case, MgSO₄) and the liters of solution.
In the problem:
Moles MgSO₄: 0.32 moles
Liters solution: 5.5L
Molarity is:
0.32 moles / 5.5L =
0.058M is molarity of the solution

How to convert 1348celsius to kelvin in stoichiometry reaction of a gas. The gas turned white not green.
Answer:
1621 K
Explanation:
How to convert 1348 celsius to kelvin
Celsius and Kelvin are both units for temperature. The relationship between both units is given as;
Kelvin (K) = Celsius ( °C ) + 273
Inserting the values from the question;
Kelvin (K) = 1348 + 273 = 1621 K

A microwave oven uses electromagnetic radiation to heat water molecules in food or drink. This radiation has a frequency of 2.45 x 10⁹ Hz. Calculate its energy
Answer:
1.62 × 10⁻²⁴ J
Explanation:
Step 1: Given and required data
Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.sStep 2: Calculate the energy (E) of this electromagnetic radiation
We will use the Planck-Einstein's relation.
E = h × ν
E = 6.63 × 10⁻³⁴ J.s × 2.45 × 10⁹ s⁻¹ = 1.62 × 10⁻²⁴ J

Your mom needs some pills from the Walgreens pharmacy for her diabetic medication. If one of the
pills weighs 650mg and the technician weighs exactly 15.6g of pills, how many pill were dispensed
and placed into the pill bottles. Show all work with units.
Answer:
24 pills
Explanation:
650 mg/1000 = 0.65 g
(There are 1000 mg in one g)
15.6g/0.65g=24
Which of the following is the mass in grams of 4.25 × 10³ mol of N2?
Answer:
119,059.5 g/mol
Explanation:
First, find the mass of N2
On the periodic table, nitrogen is 14.007
Because there are two nitrogens, multiply it by 2
14.007*2 = 28.014 g
Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier)
4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol

Combustibles fosiles ¿Por qué son inflamables los gases naturales?¿Dónde están los gases naturales?¿Cómo podemos sacar el aceite?¿Dónde está el carbón?¿Es el combustible fósil una fuente no renovable? AYUDAA
Answer:
1) Los gases naturales son inflamables porque el natural contiene metano junto con una pequeña cantidad de otros gases orgánicos, lo que hace que una mezcla de entre 5 y 15% de concentración de gas natural con aire u oxígeno se queme por completo cuando se enciende.
2) El petróleo crudo, que son depósitos de hidrocarburos que se encuentran en depósitos naturales en las formaciones subterráneas de la Tierra, se obtiene perforando un pozo en el yacimiento de petróleo a través del cual se permite que una parte importante del petróleo fluya fuera del yacimiento bajo la presión del yacimiento para recibir procesamiento e instalaciones de almacenamiento en la superficie
3) El carbón se forma cuando se aplica compactación y calor a la turba que proviene de material vegetal muerto enterrado durante un período de varios millones de años.
4) Los combustibles fósiles se consideran una fuente de combustible no renovable porque la velocidad a la que se produce es más rápida que la velocidad a la que se forma.
Una fuente de energía renovable, como la energía eólica, es producida por la naturaleza tan rápido como se consume para generar energía.
