How does molecular shape affect polarity?
A. If the molecule contains nonpolar bonds, a bent shape will make it
polar.
B. If the molecule contains atoms of similar size, polarity will cancel
out.
C. If the molecule contains more than two bonds, shape will not
affect polarity.
D. If the molecule is symmetrical, the effects of polarity will cancel
out.
Answer:
An attraction between the positive end of one molecule and the negative end of another
Explanation:
The molecular shape affects the polarity as:
A. If the molecule contains nonpolar bonds, a bent shape will make it polar.
Effect of polarity on molecular shape:The sub-atomic math of a particle influences its extremity. Every CO bond has a dipole second, however they point in inverse bearings so the net CO2 atom is nonpolar. Conversely, H2O is polar in nature of the fact that the OH bond minutes don't offset.
Thus, option A is correct.

Answer:
an acid
Explanation:
Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula HCl. Hydrochloric acid has a distinctive pungent smell. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride completely dissociates in an aqueous solution. Wikipedia
The gradual temperature change from one season to the next is due to what? view attachment
Answer:
The greenhouse effect
Explanation:
The greenhouse effect is a straightforward method that heats the Earth's exterior. When the Sun's rays touch the Earth's environment, some of it is bounced back to space and the rest is grasped and re-heated by greenhouse gases. The consumed energy heats the environment and the exterior of the Earth.

Which two rocks contain the mineral quartz?
1.
gabbro and schist
2.
dunite and sandstone
3.
granite and gneiss
4.
pumice and scoria
Answer:
3. Granite and Gneiss.
Gneiss is a coarse to medium grained banded metamorphic rock formed from igneous or sedimentary rocks during regional metamorphism. Banded gneisses called migmatites are composed of alternating light colored layers of granite or quartz feldspar and dark layers rich in biotite.
Granite is a purely natural stone that comes directly from stone quarries and is then cut into thin slabs, polished, and fabricated into countertops. So-called quartz countertops are engineered stone products that may contain a large percentage of natural quartz but may also include other minerals.

If an element has no electrons to share and is stable, what family is it found in?
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. If an element with no electrons to share belongs to noble gas family.
What is periodic table?
Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.
Noble gas is the group 18 elements whose octet is complete and they are not ready to give or take electrons from other element. They are very much stable on its own.
Therefore if an element has no electrons to share and is stable then that element belongs to group 18 or noble gas family.

given the following balanced chemical equation:
2KHCO3→K2CO3+ CO2+ H2OA.
What are the conversion factors between moles of KHCO3and moles of K2CO3?
Answer:
2 to 1
Explanation:
The reaction equation is given as:
2KHCO₃ → K₂CO₃ + CO₂ + H₂O
The conversion factor between the moles of KHCO₃ and K₂CO₃ is 2 to 1.
From the balanced chemical equation, we find out that;
2 moles of 2KHCO₃ will produce 1 mole of K₂CO₃.
So given any mole of either of the reactant or product, we can find the unknown.

Match each electron configuration to the correct element. Use the periodic table to determine the number of electrons that each element has. Drag the tiles to the correct boxes to complete the pairs.
Answer:
Explanation:
Edmentum
The arrangement of electrons within an atom's orbitals is known as its electronic configuration. The atomic number, which is equal to the number of protons in every neutral atom, is the set quantity of electrons that make up each neutral atom.
The distribution of an element's atoms' electrons throughout several atomic orbitals is symbolically represented by the electronic configuration of that element.
A standardized nomenclature is used for expressing electron configurations, in which the energy level and type of orbital are written first, followed by the number of electrons in the orbital, which is expressed in superscript.
The correct matches are:
Zn: [Ar] 3d¹⁰ 4s²
Fe: [Ar] 3d⁶ 4s²
Sn: [Kr] 4d¹⁰5s²5p²
Cl: [Ne] 3s² 3p⁵

proper regulation of the cell cycle provides which of the following benefits to multicellular organisms. select all of the correct answers.
~repair and renew wounds effectively
~replacing lost cells,such as a shed skin cell
~allows for growth
~allows for reproduction
Answer: repair and renew wounds effectively
~replacing lost cells, such as a shed skin cell
~allows for growth
~allows for reproduction
Explanation:
The cell cycle includes the various events in which a cell matures by increasing length and shape, cell replicates its genome and prepare itself for cell division.
The cells divide and replace the old and damaged cells in the multicellular organisms. Multicellular organisms are those organisms which have more than one cell.
This also helps in replacing the lost cells and helps in removing the shedding the skin cell.
This process is also useful for cellular growth and reproduction.
Which of the following represents a process in which a species is reduced?
a) Ca(s) - Ca2+ (aq)
b) Hg() - Hg22+(aq)
c) Fe2+(aq) - Fe3+(aq)
d) NO3 (aq) - NO(9)
e) 5032 (aq) - S04- (aq)
Answer:
D
Explanation:
Option D is the right answer. A substance that has been reduced undergoes chemical reduction. They show the following properties;
Removal oxygen from the species. Option D goes from 3 oxygen to just 1 oxygen. Addition of hydrogen to a specie. Gain of electrons by an atom. Decrease in oxidation number of an atom. Decrease in the number of electronegative atoms surrounding an element in changing from reactants to products.The equation that represents the process of reducing a specie is : ( D )
NO₃ (aq) - NO(g)
The reduction of a specie is a chemical reaction process which involves the removal of oxygen atom(s) and the the addition of hydrogen.
A reduced specie gains/accepts electrons therefore becoming more electronegative ( i.e. the number of electronegative atoms around it is reduced ) and It also experiences a decrease in its oxidation number
From the options provided the number of oxygen present in NO₃ reduces from O₃ to O This makes option D the correct option representing the reduction of specie
Hence we can conclude that the The equation that represents the process of reducing a specie is
NO₃ (aq) - NO(g)
