tion:What is Photosynthesis? Photosynthesis is the process by which plants, some bacteria, and some PROTISTANS use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of UNUSABLE sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the OXYGEN that we absolutely must have to stay alive. Oh yes, we need the food as well!We can write the overall reaction of this process as:6H2O + 6CO2 ----------> C6H12O6+ 6O2Most of us don't speak chemicalese, so the above chemical equation translates as:six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen

archWhat WOULD you like to ask?CHEMISTRYavatarAsked on DECEMBER 26, 2019 byRammy SalmaThe isotopic abundance of C-12 and C-14 is 98% and 2% respectively. What would be the NUMBER of C - 14 isotope in 12 g CARBON sample? ShareStudy laterANSWERIsotopic abundance of C−12 is 98%Isotopic abundance of C−14 is 2%Average atomic mass = 100Mass number×Relative abundance + Mass number×Abundance = 10098×12+2×14 =12.04 gramsSo, in 100 grams of carbon sample, C−14 isotope will be 2 grams since it is 2% in abundance.∴ in 12 grams sample, C−14 isotope will be = 10012×2 =0.24 grams1 mole of any compound has N A number of atoms i.e 6.02×10 23 . So, C−14 isotope will be 1.032×10 22Hope this will help you.

2Explanation:So, in one mile of nitrogen gas you have 6.022*10 power 23 MOLECULES of nitrogen gas. But since each INDIVIDUAL molecule consists of 2 atoms of nitrogen, the number of moles of nitrogen atoms will be twice that of nitrogen gas molecules.

rn Periodic Table The present form of a periodic table that is widely used across the globe is the long form of the periodic table. In this form of a periodic table, the horizontal ROWS are called periods and the vertical columns are known as the groups. Groups consist of elements that have similar outer shell electronic configuration in their atoms. Previously the groups were named as IA,…VIIIA, VIII, IB…VIIB and 0. But now they are named as 1, 2, 3…18. In the modern periodic table, periods are the seven horizontal rows. Principle quantum number ‘n’ decides the period of the element. Principle quantum number (n) is one of the four quantum numbers (n, l, m, and s). It tells us about the principle electron shell. For example, if n= 3, then it INDICATES the principle shell as 3. Classification of the Elements in the Periodic Table: Classification of the elements in the periodic table can be done in four WAYS on the basis of their electronic configurations: Noble gas elements: Elements of group 18 of the modern periodic table are considered a noble gas. The electronic configuration of the first element (helium) of this group is 1s2. Rest all the elements (neon, argon, krypton, xenon, and radon) have their outer shell electronic configuration is ns2np6. As the octet of these elements is complete, hence they are highly stable elements. Representative elements: S-lock and P-BLOCK elements come under the category of representative elements. Elements in groups 1 and 2 are known as the s – block elements (elements with 1s2and 2s2 outermost configuration). Group 13-17 are known as the p-block elements (outermost configuration varies from ns2np1 to ns2np5). Transition elements: Elements which belong to group 3 to 12 and have their outer shell electronic configuration as (n-1)d1-10ns1-2 are referred to as transition elements. These elements are ALSO known as the d-block elements. Inner transition elements: Lanthanides and actinides series which falls at the bottom of the periodic table comes under the category of inner transition elements. In these elements the 4f and 5f orbitals are partially filled, rendering them special properties.

━━━━━━━━━━━━━━━━━━━━━━━❤TYNDALL's effect is the appearance of light scattering on the particles of colloidal dimensions.Because of the SMALL particle SIZE, the solutions do not show Tyndall's effect. Suspensions have larger particles than colloids and thats why they show the Tyndall effect.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Molarity (M) indicates the number of moles of solute per LITER of solution (moles/Liter) and is one of the most COMMON units USED to measure the concentration of a solution.

46%Explanation:Urea= NH2- CO- NH2 And we know that Total mass of urea = 60 Mass of NITROGEN = 14 TWO MOLECULES of nitrogen= 2*14= 28 Percentage of nitrogen = Mass of Nitrogen/(Urea ) x 100 = 28/60 x 100 = 46.6% Hence Percentage of nitrogen in urea is 46%

tion:ph = power of HYDROGEN When the pH falls below normal levels, a process called demineralization occurs. ... The frequency of sugar and acid consumption can affect the pH in the mouth. The longer the mouth STAYS more acidic (with sipping), the more chances there are for cavities to form.a pH of 5.5 the teeth BEGIN to demineralize, putting them at RISK for cavities. A healthy mouth is in a neutral pH RANGE. To keep your teeth healthy, you must keep oral acidity to a minimum. Teeth can actually become stronger and remineralize when the mouth has a pH of 7.5 or above.hope it helps uh ....follow me plzzzz.......mark as brainlist

−OH group is attached with primary, secondary and tertiary alcohols with primary, secondary and tertiary carbon atoms respectively. In Victor MEYER method when these alcohols are treated with HI, AgNO 2 , HNO 2 and NaOH respectively they produce red, blue and colourless solution respectively.Victor Meyer's method:(i) The given alcohol is CONVERTED into an iodide by concentrated HI or red phosphorous and iodine.(ii) The iodide is treated with silver NITRITE to form nitroalkane.(iii) Nitroalkane is finally treated with nitrous acid (NaNO 2 +H 2 SO 4 ) and MADE alkaline with KOH.If a blood red colour is OBTAINED, the original alcohol is primary.If a blue colour is obtained, the alcohol is secondary.If no colour is produced, the alcohol is tertiary.
