what is the molecular polarity of the following lewis structure
Is the method for converting molecules to moles the same as that for atoms?
Answer:
One mole is the Avogadro's number of particles (atoms, molecules, ions or electrons) in a substance. Converting to moles is fairly easy because the conversion is always the same.
The smallest fundamental of an element is called an atom while two or more atoms join together to produce a molecule. Molecules are the fundamental of any given compound or a substance.
Yes, the method of converting molecules and atoms to moles are similar.
The method of conversion can be explained as:The moles are defined by the presence of Avogadro's number that gives the number of particles present in a substance.The method of converting molecules into moles requires the division of the molecules by [tex]6.02 \times 10^{23}[/tex]. This number which is used in dividing is called Avogadro's number.For converting atoms into moles the number of atoms is divided with the Avogadro's number [tex]6.02 \times 10^{23}[/tex].Therefore, the conversion to moles is easy and the same.

if an ion has 13 protons and 10 electrons what is the charge on the ion?
Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
Explanation:
The ion will have a charge of +3
The components of an atom and their charges are:
protons which have a positive charge electrons which have a negative charge neutrons which have no chargeThe charge of an ion will therefore depend on the number of electrons and protons as they cancel each other out.
The number of excess protons in this ion will be:
= Number of protons - number of electrons
= 13 - 10
= 3
Protons have a positive charge so there will be a charge of +3 as there are 3 excess protons.
In conclusion, this ion will have a charge of +3.

Determine the final temperature of sample with a specific heat of 1.1 J/g°C and a mass of 385 g if it starts out at a temperature of 19.5°C and 885 J of energy are added to it.
Answer:
T2 =21.52°C
Explanation:
Given data:
Specific heat capacity of sample = 1.1 J/g.°C
Mass of sample = 385 g
Initial temperature = 19.5°C
Heat absorbed = 885 J
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = Final temperature - initial temperature
885J = 385 g× 1.1 J/g.°C×(T2 - 19.5°C )
885 J = 423.5 J/°C× (T2 - 19.5°C )
885 J / 423.5 J/°C = (T2 - 19.5°C )
2.02°C = (T2 - 19.5°C )
T2 = 2.02°C + 19.5°C
T2 =21.52°C

Which helps regulate the temperature range of the Earth's atmosphere? Water or Land
Answer:
The oceans atmosphere. AKA Water.
Explanation:
The oceans and the atmosphere are the two large reservoirs of water in the Earth's hydrologic cycle. The two systems are complexly linked to one another and are responsible for Earth's weather and climate. The oceans help to regulate temperature in the lower part of the atmosphere.
Earth's atmosphere get warm up by the temperature absorbed by the gases in the atmosphere. However it can balanced water in earth such as ocean currents and cooling.
What is ocean currents?Ocean currents are formed from the pressure difference in ocean level and thus in day time there will be winds from ocean to land which cools the earth's surface.
Surface of the earth warms up by absorption of heat energy from sun. This warming will be higher if there are more greenhouse gases such as carbon dioxide, methane oxides of nitrogen, Sulphur etc.
Greenhouse gases intensely absorbs the temperature from radiation and thus increase the temperature of earth's surface. These gases are mainly evolved to the atmosphere by industries and factories.
Other factor which affects the temperature of earth surface include wind, ocean level etc. The level of ocean and ocean currents helps to regulate the temperature of the surface and make it cool.

25.00 g of the compound is composed of 6.77 g of tin and 18.23 g of bromine. What is the percent by mass of tin in the compound? Show work.
The percent by mass of Tin : = 27.08%
Further explanationGiven
25.00 g of the compound
6.77 g of Tin
18.23 g of Bromine
Required
The percent by mass of Tin
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements
%mass X = (mass X/mass sample) x 100%
So %mass of Tin :
= (6.77 g : 25 g) x 100%
= 27.08%

What characteristic of an element’s atoms always determines the element’s identity?
Answer:
Number of protons
Explanation:
There are three sub atomic particles. These are;
- Protons
- Electrons
- Neutrons
Among these three particles, only one determines the identity of the element. This is the Protons. The number of protons which is also called the atomic number determines the identity of an element. For instance, atom with one proton is Hydrogen and n other element can have atomic number of one.

The sun’s core is made of solid rock. True or false
Answer:
False
Explanation:
Heres what its made of:
The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.
Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis?
Not enough sunlight is captured in these areas of the leaves.
Carbon dioxide cannot enter these areas of the leaves.
Too much glucose builds up in these areas of the leaves.
Oxygen cannot be released in these areas of the leaves
Answer:
Not enough sunlight is captured in these areas of the leaves.
Explanation:
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
The sunlight is the energy source which drives this chemical change or reaction.
Therefore, to capture the sunlight, the green pigment called chlorophyll is needed. Without this sunlight, photosynthesis will not take place. Photosynthesis is a light dependent reaction. Without light, the process is greatly hamperedOMG PLS ANSWER IM USING SO MANY P OINTS I SWEAR I NEED
