Compare and contrast the alkaline battery and a Zinc carbon battery. put in some other facts about them too. write somewhere around 2 paragraphs.



I'll mark brainlyest to whoever has the best answer and give them 50 points for helping me.

Answers

Answer 1
The alkaline batteries, have a higher energy density and the time a battery can remain in storage without losing any of its capacity. Also, there is a specially designed coating inside the batteries that reduces contact resistance for greater reliability. Lastly, the alkaline cells have an extra power formula to maintain power for a longer period of time in high drain devices. Alkaline batteries provide more energy than zinc carbon batteries.

The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.

The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

Hope this helps! :)

Pollen is transferred from the stamen of one flower to the stigma of another. What has occurred?

Answers

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?

Answers

Answer:

the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Answer:

[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).

In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.

What is the difference between a homogeneous and heterogeneous mixture?

Answers

A homogeneous mixture is made up of multiple different substances. (You can see different parts)
Ex: Cereal in milk or ice in soda

A heterogeneous mixture is a mixture that is mixed well. ( you can’t see the different parts)
Ex: Rain or air
You wake up in the morning and make yourself a cup of coffee. You pour the coffee in your cup, add milk, add sugar, and stir everything together. The result is a uniform cup of caffeinated goodness. Each sip should taste and look the same.

This is an example of a homogeneous mixture. In this type of mixture, the components are evenly distributed throughout and the mixture has a uniform appearance. You shouldn't be able to pick out the individual components. Additionally, you can describe a homogeneous mixture as having only one phase. A phase is any part of the mixture that has the same chemical properties and uniform distribution of the components.


Heterogeneous

When you're eating a bowl of cereal, you are consuming a heterogeneous mixture. You can easily see the different things that make up this mixture: the milk and the cereal. Each spoonful will have different distributions of the components.

A heterogeneous mixture has components that are not evenly distributed. This means that you can easily distinguish between the different components. A heterogeneous mixture has two or more phases. This doesn't necessarily mean phases of matter, like liquid or solid. For example, a mixture of water and oil has two liquid phases. Each phase has its own distinct chemical properties.

Please look at these, i'm confused, i need the questions answered, and i need a graph or just need to know how to make the graph (idk how).

Answers

Set up a graph that shows voltage on the x axis and the number of paper clips picked up on the y axis.

When you graph anything your points are made up of an x value and a y value (x,y).

You’re going to use the voltage as your x value and the average number of paper clips picked up at that given voltage as your y value.

I’ll do the first one for you! For the 25-turn electromagnet at a voltage of 1.5V the average number of paper clips picked up was 6. Giving us the point (1.5,6) that’s what you should be graphing. Do the same for all of the others.

What causes the electrons to move and form static electricity?
moist air
dry air
friction

Answers

Answer:

friction

Explanation:

The rubbing of certain materials against one another can transfer negative charges, or electrons.

The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.

What is static electricity ?

Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.

These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.

The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.

Energy can be neither created nor destroyed. This fact means that even though energy sources can be depleted (used up), the energy in them is not destroyed. Instead, it is transformed to other forms of energy. And almost all energy resources here on Earth can have their energy traced back to the Sun’s gravitational or light energy.

Electricity is often thought of as a secondary source of energy because it must be gained by transforming some other kind of energy (a primary source). Think about where the electricity generated by a wind turbine comes from. Describe the path that wind energy takes from the Sun’s light to electricity.
