2.How many atoms are in mercury (I) phospate? The chemical formula is (Hg2)3(PO4)2

3.The burning of hexane is shown in the following chemical equation. How many oxygens are in the products to the right of the arrow? 2C6H14 + 19O2 → 12CO2 + 14H2O + heat

Answer:

Add x on all of them I just took what ur taking rn !!!!!

Explanation:

because the other guy said the same thing

Answer:

no molecule and properties or defent

Answer:

it would most likely occur

———————————————————————————————————————

Across a semi-permeable membrane that separates solutions of different concentrations

———————————————————————————————————————

this is because osmosis is the ‘net’ movement of molecules from a ‘region’ of ‘higher concentration’ to a ‘region’ of ‘lower concentration’ ‘down the concentration gradient’.

Answer:

XD ok wheres the paper

Explanation:

Answer:The atoms you need to build are on the right. You need three colors, and need to say what each color is. Each color should represent a different element.

Explanation:

Answer:

The atoms you need to build are on the right . You need three colors and you need to say what the colors are. Each color should represent a different element.

Explanation:

You just need to do what it says. Build the model or use some things as substitutes if you are missing an ingredient and write down what you identified.

There isn't really much better help I could give, sorry. I hope this helps.

Answer:Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy. ..

Explanation:This movement is a form of kinetic energy, and the more the molecules move the more kinetic energy they have. Molecules in solids don't move much, they just vibrate

Answer:

ANS is potential energy

Hope it helps

Answer:

Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

Answer:

Reproduction is the function of process by which organisms replicate themselves. In a general sense reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species.

Have a great day friend! :D

During autumn, several changes occur in nature. Some of the changes that happen during this season include:Days become cooler and shorter,animals prepare to survive the winter.some trees begin to shed their leaves and plants prepare to survive winter, thus all options are correct.

1. Days become cooler and shorter: As autumn arrives, the weather gradually becomes cooler. The days also become shorter, meaning there is less sunlight each day. This decrease in daylight hours is due to the Earth's tilt on its axis as it orbits the sun.

2. Animals prepare to survive the winter: Many animals start making preparations for the upcoming winter during autumn. They may begin to store food or find sheltered places to hibernate. For example, squirrels gather and store nuts, birds migrate to warmer regions, and bears build up fat reserves for hibernation.

3. Some trees begin to shed their leaves: One of the most notable changes during autumn is the colorful transformation of tree leaves. Some trees, such as deciduous trees, shed their leaves during this season. As the days shorten and temperatures drop, the trees receive less sunlight, which triggers the production of a pigment called anthocyanin. This pigment gives leaves their vibrant red, orange, and yellow colors before they eventually fall off.

4. Plants prepare to survive the winter: Just like animals, plants also make preparations to survive the harsh conditions of winter. They may enter a state of dormancy or store energy and nutrients in their roots to survive until spring. Some plants produce seeds or fruits during autumn, ensuring their offspring can grow when conditions become favorable again.

In summary, during autumn, days become cooler and shorter, animals prepare for winter, some trees shed their leaves, and plants make preparations to survive until spring. These changes are part of the natural cycle of life and adaptation to seasonal variations.Thus, all options are correct.

Answer:

4

Explanation:

density= mass/volume

Answer:

100kg

Explanation:

[tex]density= mass/volume[/tex]

using this formula you can re arrange the equation my moving the volume onto the opposite side

giving you this formula : mass= density x volume

in doing so you can calculate the mass of the object by extracting the relevant information of the question

density=20g/ml

volume=5ml

mass = density x volume

=20 x 5

= 100

Answer:

Maybe C. But we dont know the equation.
