In the above figure, what type of bond is formed?
metallic
ionic
covalent
nonpolar
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.

what is photosysthies
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Explanation:
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants. Plants are also crucial to human life because we rely on them as a source of food for ourselves and for the animals that we eat.

Help out please????
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.

Imagine disease kills 85 percent of the wolf population. How will it affect the other organisms?
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:
most elements are metals
Sodium, Calcium, and Mercury are all examples of
a. metals
b. non metals
C. metalloids
D. none of the above
Answer:
c
Explanation:
Answer:
None of the above
Explanation:
Mercury is a planet of the 8 planets, Sodium is a mineral that occurs naturally in foods or is added during manufacturing - or both. 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. About 99% of the calcium in our bodies is in our bones and teeth.
How many moles are there in 17.6g NaOH?
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.
What is mole?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.

Pls help me with this question:As a result of this process offspring 1 and offspring 2 will have?
A.the same number of genes but different traits
B.a different number of genes but the same traits
C.the same number of genes and the same traits
D.a different number of genes and different traits
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.
What is asexual reproduction?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.

Using the balanced equation below, how many moles of water can be produced when 4 grams of Hydrogen react?
Answer:
2 moles of water (H₂O)
Explanation:
We'll begin by calculating the number of mole in 4 g of Hydrogen. This can be obtained as follow:
Mass of H₂ = 4 g
Molar mass of H₂ = 2 × 1 = 2 g/mol
Mole of H₂ =?
Mole = mass / Molar mass
Mole of H₂ = 4/2
Mole of H₂ = 2 moles
Finally, we shall determine the number of mole of water (H₂O) produced by the reaction of 4 g (i.e 2 moles) of H₂. This can be obtained as follow:
2H₂ + O₂ —> 2H₂O
From the balanced equation above, we can see that 2 moles of H₂ reacted to produce 2 moles of H₂O.
Thus, 2 moles of water (H₂O) were obtained from the reaction.

A.as solids
B.never
C.as both liquids and solids
D.As liquids
Answer:
C. as both liquids and solids
Explanation:
The ionic compounds are good conductors of electricity when they exist as both liquids and solids.
What are ionic compounds?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.
