Answer:

A and B are the correct answers.

Answer:

A and B are correct

Explanation:

<em>A</em> and <em>B</em> are the most logical answers from the 4 given. This is because just like the moon and Earth, Earth keeps the moon in its orbit with gravity.

A gravitational force can happen with any two objects in the universe. An example of this is a passing asteroid being pulled into Jupiter's atmosphere, because of the gravitational pull. Even two asteroids can have a gravitational pull/force on each other. If there is a big asteroid with smaller asteroids surrounding it, the smaller asteroids will "follow" the larger asteroid.

C is false, because the bigger the mass the bigger the pull (gravitational)

D is also false because if the gravitational force could only exist if there was contact, logically then the moon wouldn't still be orbiting Earth. In other words "Does the moon touch the Earth?" No, it does not "Is the moon still orbiting around Earth without contact?" Yes it is

What purpose does ammonia lauryl sulfate serve as a surfactor
Alborosie

Answer:

See below  

Step-by-step explanation:

Ammonium lauryl sulfate has the structural formula CH₃CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂CH₂OSO₂O⁻ NH₄⁺.

The long nonpolar hydrocarbon chain and the ionic sulfate end group make it a surfactant.  

The ionic end tends to dissolve in water, but the nonpolar chain does not. This makes the compound an excellent <em>foaming agent,</em> so it is used in many shampoos and toothpastes.

The molecules form <em>micelles</em> in water, small spherical shapes with the polar heads outside, facing the water, and the nonpolar tails are inside.

They reduce the surface tension or the water so that, when you brush your teeth or shampoo your hair, the air bubbles are stable and do not break.

15 grams of sodium reacts with a certain amount of chlorine to yield 37 grams of sodium chloride, as shown below.
ale4655 [162]

Answer: 22g of chlorine would be needed to carry out this synthesis reaction

Explanation:

A synthesis reaction is one in which two or more than two elements combine together to forma single product.

Na+Cl\rightarrow NaCl

The atoms present in the reactants are found on the product side. According to the law of conservation of mass, the number of atoms on both sides of the arrow must be same as the total mass must be conserved.

15 grams of sodium reacts with 22 grams of chlorine to yield 37 grams of sodium chloride. Thus 22g of chlorine would be needed to carry out this synthesis reaction.

4 3 and 5 are wrong:)

4 is true and 5 is false

4. insulators are really thick materials that keep electrons within their space.

For example, a charger the rubber is the insulators and the electrons are flowing inside of the charger so you don't get shocked.

5. without the force of attraction, there are no atoms:)

for number 3, its a trick question

Hope this helped!

(learned these this year so I didn't forget them:)
