If a sample of pure calcium 9Ca) contains 4.69 x 1022 atoms of iodine, there are 0.0779 moles of calcium in the sample. The correct answer will be A.
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
Answer:
D. visible light and the electromagnetic spectrum
have a small area of overlap.
Explanation:
you have to look careful in answering questions you could end up right or wrong, on these answers are very important to know, and I am always right with these answer's
Step one write the chemical equation for reaction
= Ag2O + 2(C10H10N4SO2)---> 2 ( AgC10H9N4SO2)
The reacting ratio of Ag2O to AgC10H9N4SO2 is 1:2 from the reaction above
step 2; find the number of moles of AgC10H9N4SO2
that is mass/molar mass
The molar mass of AgC10H9N4SO2 = 107.86 +(12 x10) + (1 x 9) + (4 x 14) +32 +(16 x2) =356.86g/mol
moles is therefore= 25g/356.86g/mol= 0.07moles
by use of mole ratio the moles of Ag2O= 0.0702=0.035moles
mass = moles x molar mass
the molar mass of Ag2O=231.72 g/mol
mass is therefore= 231.72g/mol x 0.035moles= 8.11grams
1) This type of energy transfer is called conduction.
2) Hydroelectricity
3) petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. All of these come out of oil refining process
Hope this helped and plz mark as brainliest!
