Answer:
Opposite.
Water exhibits negative charge near hydrogen, positive near oxygen.
This is why it is OPPOSITE.
Let me know if this helps!
Water is a polar compound because it exhibits opposite charges. Therefore, option C is correct.
What is polar compound ?The term polar compound is defined as the compound with distinct regions of positive and negative charge, as a result of bonding with atoms such as nitrogen, oxygen, or sulfur.
Water is a polar compound because the covalent bonds between hydrogen and oxygen in the water molecule are polar in nature. Any molecule with lone pairs of electrons around the central atom is polar compound.
In water there are two atoms are present that are oxygen and hydrogen. Hydrogen has positive charge while oxygen has negative charge,
Thus, Water is a polar compound because it exhibits opposite charges, option C is correct.

What is Mendeleev’s Periodic Law? How many elements were classified by Mendeleev?
Answer:
1.the law that the properties of the elements are periodic functions of their atomic numbers. Also called Mendeleev's law. (originally) the statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.
Explanation:
2.Mendeleev’s Periodic Law states that the properties of elements are the periodic function of their relative atomic masses. Mendeleev arranged all 63 elements; which were discovered till his time; in the order of their increasing relative atomic masses in a tabular form. It is known as Mendeleev’s Periodic Table.

1. If I have 3 identical books that all have a length of 25cm, a
width of 15cm, and are 11cm tall, what would be the volume of
all 3 books?
Answer:
12,375 cm³
Explanation:
v=l×w×h
Since there are 3 books the equation would then be
v=3(l×w×h)
v=3(25×15×11)
v=3(4,125)
v=12,375 cm³

which option correctly shows the bond angle of a linear molecule?
a. 109.5 degrees
b. 90 degrees
c. 120 degrees
d. 180 degrees
Taking into account the definition of molecular geometry, the correct option is option d.: the bond angle of a linear molecule is 180 degrees.
In first place, molecular geometry or molecular structure is the spatial distribution of atoms around a central atom. Atoms represent regions where there is a high electron density, and are therefore considered electronic groups, regardless of the bonds they form.
That is, molecular geometry is the three-dimensional arrangement of the atoms that make up a molecule.
The molecular geometry of an element characterizes some of its physical or chemical properties, such as boiling point, viscosity, and density.
Linear molecules are molecules of the AB₂ type in which the central atom does not have lone pairs. To avoid repulsions between the binding pairs, arrange the B groups as far apart as possible. For that they must oppose each other 180 °.
In summary, linear molecular geometry describes the arrangement of different atoms with 180º bonds.
So, the correct option is option d.: the bond angle of a linear molecule is 180 degrees.

What is the molarity of a 50.0ml aqueous solution containing 10.0 grams of hydrogen peroxide H2O2
Molarity= No of moles of solute * 1000 / vol solution in ml
No of moles= Given mass / Molar mass
Given Mass of solute (H2O2)= 10g
Molar mass of H2O2=34gmol^-1
No of moles= 10/34= 0.294 moles
Volume of solution=50ml
Molarity = 0.294*1000 / 50
Molarity = 5.8M

conservation of matter, which of the following could be a product?
O A. NaOH
O B. Ag2CO3
O C. CaCO3
O D. AgNO3
Answer:
The answer is "Option B"
Explanation:
Law:
In the law of the conservation of matter, states the volume of matter throughout the process remains constant. In any particular case, it is closed to the movement of matter. It is mostly on conservation of energy means, that the total mass of the products should consider the sum of the mass, which is the reactant of the event of chemical processes.

An event planner accidentally leaves a tray of cupcakes in his car for several hours on a sunny day. When he returns, the formerly firm frosting is now runny and wet to the touch. Which answer choice best describes what happened in this scenario? The particles of frosting released energy to their surroundings and changed from the solid to the liquid state. The particles of frosting released energy to their surroundings and changed from the liquid to the solid state. The particles of frosting absorbed energy from their surroundings and changed from the solid to the liquid state. The particles of frosting absorbed energy from their surroundings and changed from the liquid to the solid state.
Answer:
The particles of frosting absorbed energy from their surroundings and changed from the solid to the liquid state.
Explanation:
On a sunny day, the energy of the particles in the surrounding is higher than the energy of the frosting tray of cupcakes.
As a result of the exchange of energy between the tray of cupcakes and the surrounding, the tray of cupcakes absorbs energy from the surrounding. When this occurs, the firm frosting is now converted from solid to liquid which is runny and wet to touch, hence the answer above.
