why are atoms attracted to each other in an ionic bond?
Answer:
The answer is C. Inversely, when this atom gains a positively charged ion. (The atom) becomes a negatively charged atom or an "anion".
Explanation:
Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged, an atom that gains one or more electrons becomes negatively charged. The oppositely charged ions attract each other to form ionic networks (or lattices)
Answer:
opposite charges attract
Explanation: Ionic bonding is the attraction between positive and negative charge ions electrostatics explains why this happens: opposite charges attract and like charges repel. when many ions attract each other, they form large, ordered, crystal lattices in which each ion is surrounded by ions of the opposite charge.

A regulation NBA basketball has a radius of 12 cm when inflated properly. What is the volume of an inflated basketball in cm^3?
someone help lol
Answer:
The volume of basketball is 7216.5 cm³.
Explanation:
Given data:
Radius of ball = 12 cm
Volume of ball = ?
Solution:
We will apply the volume formula of sphere.
V = 4/3 ×π×r³
we know that,
π = 22/7
r = 12 cm
Now we will put the values in formula.
V = 4/3 × 3.14 × (12 cm)³
V = 4/3 × 3.14 ×1728 cm³
V = 7216.5 cm³
Thus, the volume of basketball is 7216.5 cm³.
If a spacecraft was parked on Venus and needed to make a flight to Jupiter, how far would it need to travel? Please show your work.
Answer:
If a spacecraft was parked on Venus and needed to make a flight to Jupiter, it would need to travel 670,338,270 km.
Explanation:
Jupiter - Various Properties
Jupiter Meaning:
Jupiter is the largest planet in the solar system. Fittingly, it was named after the king of the gods in Roman mythology. In a similar manner, the ancient Greeks named the planet after Zeus, the king of the Greek pantheon.
Jupiter is a gas giant that is the 5th planet from the sun. It is known as the biggest planet in the solar system. It is a very marvelous planet regarding the characteristics of the atmosphere and “surface” of the planet.The planet is a gas giant, so the whole planet that could’ve been the crust and the mantle is full of poisonous gases. Except for the core, it is full of rocky metals. The planet Jupiter has approximately 70 moons. Jupiter has a high gravitational pull, so it can easily grasp some satellites or other rocky bodies into its collection.Jupiter’s distance from the sun is 483.8 million miles.It’s orbital period is 12 earth years.Jupiter’s length of a day is 9 hours and 56 minutes.Jupiter has a radius of 43,441 miles.Has a gravity of 24.79 m/s squared.Venus - Various Properties
It's very hot. It has a thick dense atmosphere bloated with strong greenhouse gasses.Its also the second brightest celestial body when viewed from Earth due to its reflective gasses.It is also very volcanically active. From what we know now, Venus has no tectonic plates.Venus is also very similar in size to Earth.Venus Meaning:
Venus (plural veneres) is the Latin word for ‘loveliness,’ ‘beauty,’ ‘charm,’ It is derived from Proto-Italic *wenos- ('desire'). The ultimate source is the Proto-Indo-European (PIE) *wenh₁-os ('desire').
---------------------------------------------------------------------------------------------------To calculate how far the spacecraft would need to fly is to calculate the distance betwen Venus and Jupiter.
To save energy, let's consider a Hohmann transfer orbit, an ellipse tangent to opposite sides of Venus's and Jupiter's orbits. The spacecraft would follow the outbound half of this orbit, departing ahead of Venus and arriving as Jupiter overtakes it.
Depending on where in Jupiter's orbit the spacecraft meets it, this orbit has semi-major axis a = (rV + rJ) / 2 = 2.96±0.03 au and period of a3/2 = 5.10±0.08 years. The outbound half has a path length of 7.78±0.07 au and takes 2.55±0.04 years. As Jupiter moves 72° to 84° around the Sun in that time, the launch window is when Venus's heliocentric ecliptic longitude is 96° to 108° behind Jupiter's.
To convert au to km, multiply by 1.496 × 108 km / au.

Answer:
If a spacecraft was parked on Venus and needed to make a flight to Jupiter, it would need to travel 670,338,270 km.

LOL idk what this question is about but to my understanding, having a detailed procedure gives u more clue on what u r doing and how u r doing it. think of this like a instruction manual, if u want to build a telescope and have no idea how to build it and the instrutions only give u short sentences like"screw nails next to the finger scope" or something like that wouldnt help much. i dont know about u but i rather prefer instructions written like this"first screw the nail beside the finger scope, DO NOT unscrew the botton" and continue. i cant build a telescope so yea dont know any directions to that.
Desmond wanted to paint his bedroom. He went to the hardware store and was shown a variety of different paint colors from which to pick. Paint is an example of which kind of product, Which is made with chemicals by humans?
Answer:
led
Explanation:
Paint is kind of synthetic chemical product.
What is paint?Paint is any colored liquid, liquefiable, or solid mastic substance that solidifies after being applied in a thin layer to a substrate.
Pigments, binders, solvents, and additives are the four major components of all paints. Binders work to "bind" the pigments together and create the paint film, while pigments offer color and conceal. Additives are substances that give certain paint features such as mildew resistance, while solvents are liquids that suspend the components and allow you to deposit the paint on the surfaces. All four elements work together to create paint that is tailored to your exact design requirements.

Compare and contrast the concepts of average mass and relative mass. Which one is more accurate, and why? Why is the one you did not choose inaccurate?
Answer:
Relative and average atomic mass both describe properties of an element related to its different isotopes.
Explanation:However, relative atomic mass is a standardized number that's assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.
Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate.
What is mass?Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.
The relative mass is the mass that is with respect to mass of a matter that is considered as standard. In chemistry relative mass is equal to the mass of one-twelfth the mass of [tex]C-12[/tex] isotope .
Out of relative and average atomic mass, relative atomic mass is more accurate as it is calculated with respect to a standard quantity.
Thus Relative atomic mass is more accurate than average atomic mass.

When the temperature goes up, the pressure will go up.
What is the reason?
Mention a real-world example?
Explanation:
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
For example, if an engineer has to store 600g of oxygen in a container and that oxygen needs to be kept at a pressure of 1 atm and a temperature of 125 degrees Fahrenheit, then this theorem (which is called Ideal Gas Law) is used to figure out what volume of a container needs to be built.

Answer:
[tex]\huge\boxed{\sf 1.51\ L}[/tex]
Explanation:
From the reaction:
2 moles of Na produce 1 mole of H₂
Converting 3.10 g of Na into moles:
Moles = mass / molar mass
= 3.10 / 23
= 0.135 mol
From the reaction:
2 Na = 1 H₂
1 Na = 1/2 H₂
1 Na = 0.5 H₂
1 mol of Na = 0.5 mol of H₂
0.135 mol of Na = 0.5 × 0.135 mol of H₂
0.135 mol of Na = 0.067 mol of H₂
So, 0.135 mol of Na (3.10 g) produce 0.067 mol of H₂
Convert 0.067 mol of H₂ into L:
= mol × molar value
[molar value = 22.4 L/mol]
= 0.067 × 22.4
= 1.51 L
