Write a scientific explanation that compares the electrical forces of ethanol, hexane, and water.
Claim:

Reasoning:
Answers
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."

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
Answers
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

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
Answers
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.

Which of the following is the mass in grams of 4.25 × 10³ mol of N2?
Answers
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
