we know the formula to convert farenheit to Celsius

=(F-32)(5/9)

=(107-32)(5/9)

(5/9)=375/9= 41.6 degrees Celsius

Answer:

I believe it’s C

Explanation:

I used Socratic and found a quizlet lol

The organism is reproducing asexually. Hence both offspring has the same number of genes and same traits.

Asexual reproduction allows for the rapid production of vast numbers of children by a single person. Asexual reproduction is a successful method of reproduction in a stable or predictable environment since all the children will be suited to that environment.

Asexually reproducing organisms may be at a disadvantage in an unstable or unpredictable environment since all of the progeny are genetically similar and might not have the genetic diversity to survive in new or changing settings.

Therefore, the given diagram describes the reproduction of an organism by asexual method and giving offsprings of same number of genes and same traits. Hence, option C is correct.

Answer:

It is an covalent bond.

Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.

Answer:

The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.44moles are there in 17.6g NaOH.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. The stoichiometry represents the number of moles.

Mathematically,

number of moles of NaOH =given mass of NaOH÷ molar mass of NaOH

Molar mass of 1 mole of NaOH= 40 g/mol

mass of NaOH=  17.6g

Substituting all the given values in the above equation, we get

number of moles of NaOH = 17.6g ÷  40 g/mol

number of moles of NaOH  =0.44moles

Therefore, 0.44moles are there in 17.6g NaOH.

Naturally occurring sodium is in foods such as celery, beets and milk. Packaged and prepared foods can be big sodium culprits, AND Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat.

7.27 mol C4H6

Explanation:

To calculate moles, divide the molar mass by the grams given

To find molar mass, add the atomic mass of the elements

12.011*4 + 1.008*6 = 54.092 g/mol

393 g * 1 mol/54.092 g = 7.265 mol

Answer:

Because it helps predict the types of chemical reactions that a particular element is likely to participate in by telling each element's atomic number and usually its atomic weight

Explanation:

Answer:

An element with 1only one valence electron is extremely reactive while an element with 8 valence electrons is very stable and does not react most of the times

Explanation:

Valency is the number of electrons in the outermost shell of the atom. It shows the ease with which elements react and combine with each other.

An element can take a maximum of 8 electrons in most of its outermost shells. As a matter of fact, the goal for its stability is to attain a structure with all 8 slots for electrons in its outer shell filled up. The element can either do this by adding or removing electrons.

The ease with which it adds or removes the electrons shows its reactivity. If it has only one electron to lose, (the valence electron) the element will be very reactive because this is relatively easier to do when compared with 2 electrons, three electrons,  and so on. An element with 8 electrons in its outer shell is very stable and does not need to react anymore. an example of this is Neon and Argon.

Answer:

To avoid spattering

Explanation:

If we are heating a hydrate to drive off the water of crystallization, we must initially heat the hydrate gently, at a lower temperature and then more strongly only after most of the water has been driven off in order to to prevent spattering.

Since we obtain the amount of water by the mass difference, Spattering  decreases the mass of water obtained and ultimately results in a lower percent of water being calculated for the hydrate.

Answer:

There would most likely be an overpopulation of the animals the wolfs ate.

Explanation:

Answer:

Many populations will grow way to much. Also others will drop in numbers drastically.

Explanation:

Due to the fact that wolves are predators, the prey they eat will grow 85% more. Now, 85% of the wolf population dies, that`s a lot of prey not eaten. Then the prey that are predators to other animals who are over hunted by their predators will most likely drop in numbers drastically, by I mean 85%. This will throw the ecosystem off so much, humans could be at grave risk.

Answer:

C. as both liquids and solids

Explanation:

The ionic compounds are  good conductors of electricity when they exist as both liquids and solids.

Ionic compound or electrovalent compound is a type of compound  which is formed between two elements when there is an exchange of electrons which takes place between  the atoms resulting in the formation of ions.

When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge  and forms an ion called the anion.

As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.They are good conductors of electricity of heat, They are hard and brittle and even used as electrolytes.

Answer:

B. X= Elements, Y= Compounds

Explanation:

An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.

Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.
