Answer:

Batteries work by letting charged ions flow through an electrolyte solution.

A battery is a device that consists of one or more electrochemical cells that can convert stored chemical energy into electrical current. Each cell consists of a positive electrode, or anode, a negative electrode, or cathode, and electrolytes that allow ions to move between the electrodes, allowing current to flow out of the battery to carry out its function.

Explanation:

Its operation is essentially based on a reversible chemical process called reduction-oxidation, in which one of the components is oxidized and the other is reduced; that is, a process whose components are neither consumed nor lost, but merely change their oxidation state, and which in turn can return to their original state under the right circumstances.

List the number of each type of atom on the left side of the equation 2C6H14(l)+19O2(g)→12CO2(g)+14H2O(g) Enter your answers sep

<u>Answer:</u> The number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

<u>Explanation:</u>

In a chemical equation, the chemical species are termed as reactants or products.

Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.

For the given chemical equation:

$2C_6H_{14}(l)+19O_2(g)\rightarrow 12CO_2(g)+14H_2O(g)$

On the reactant side:

Number of carbon atoms = (6 × 2) = 12

Number of hydrogen atoms = (14 × 2) = 28

Number of oxygen atoms = (2 × 19) = 38

Hence, the number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

If Mary drove 525miles in 7hours at an average speed of 75 miles per hour how much faster would her average speed need to be to

Makovka662 [10]

<h3>Answer:</h3>

30 miles per hour faster

<h3>Explanation:</h3>

We are given;

Distance that Mary drove as 525 miles
Time she took as 7 hours
Average speed as 75 miles per hour

We are supposed to determine how fast the average speed would be if she made the trip in 5 hours.

We know that speed is given by dividing distance by time taken.
In this case distance remained constant

Therefore, we can determine the speed when she took 5 hours

Speed = Distance ÷ time

= 525 miles ÷ 5 hours

= 105 hours

Thus, the new speed would be 105 miles per hours

But, initial speed was 75 miles per hour

Therefore, she would travel 30 miles per hour faster to cover the journey in 5 hours.

What do you notice about the relationship between the force strength and the size of the velocity change? HELP MEEEEE

natka813 [3]

Answer: As mass is constant during free-weight resistance training, a greater impulse will result in a greater velocity. Therefore, as generation of force greater than the weight of the resistance increases higher movement velocities and decreased movement times result. (from google)

Explanation: hope this helps! :)
