Answer: option A

The electrons are attracted to the protons

Explanation:

Electrostatics is a force that pull or push objects without the objects actually touching them.

Electrons have a negative charge and protons have a positive charge. Positive and negative attract each other so therefore the electrons are attracted to the protons.

It’s not B because the electrons aren’t 100% pushing away from the nucleus.

It’s not C because the electrons are not attracted to the neutrons. Neutrons don’t have a charge; they have a net zero charge.

It’s not D because the electrons can’t attract each other. Electrons have a negative charge and negative charges don’t attract each other; they push away from each other instead.

Hope that helps.

When water is electrolyzed, it splits into hydrogen and oxygen.

Westkost [7]

The mass of water is equal to the combined mass of hydrogen and oxygen.

This is defined as the quantity of matter in a physical body. The electrolysis reaction of water can be seen below:

2 H₂O ---> 2 H₂ + O₂

We can deduce that 36 grams of H₂O dissociated to give 4 grams of H₂ and 32 grams of O₂ which option D was chosen as the appropriate choice.

While driving your rental car on your vacation in Europe, you find that you are getting 8.8 km/L of gasoline. What does this val

gizmo_the_mogwai [7]

Answer : The value correspond to in miles per gallon is, 20.6976 mile/gallon

Explanation :

The conversion used to convert kilometer to miles is:

1 km = 0.6214 miles

The conversion used to convert liter to gallon is:

1 L = 0.2642 gallons

Thus,

1 km/L = $\frac{0.6214}{0.2642}mile/gallon$

1 km/L = 2.352 mile/gallon

As we are given that 8.8 km/L of gasoline. Now we have to convert it into mile/gallon.

As, 1 km/L = 2.352 mile/gallon

So, 8.8 km/L = $\frac{8.8km/L}{1km/L}\times 2.352mile/gallon$

= 20.6976 mile/gallon

Thus, the value correspond to in miles per gallon is, 20.6976 mile/gallon

What is the relationship between concentration and rate of reaction?

grigory [225]

<h3><u>Answer;</u></h3>

Directly proportional

<h3><u>Explanation;</u></h3>

<em><u>Concentration is one of the factors that determine the rate of a reaction. Reaction rates increases with increase in the concentration of the reactants, which means they are directly proportional.</u></em>
An increase in the concentration of reactants produces more collisions and thus increasing the rate at which the reaction is taking place. Therefore, <u>Increasing the concentration of a reactant increases the frequency of collisions between reactants and will cause an increase in the rate of reaction.</u>
