  • F (x)=6x-9 L=-3 c=1 ε=0. 01 find the δ gt;0 help me to get the . . . - Socratic
    We know the following #epsilon-delta# Definition of Limit : #AA epsilon > 0, EE" a "delta > 0," such that, "#
  • Question #b5e69 - Socratic
    3 01 xx 10^21" molecules O"_2 M_ (CO_2) = "220 mg" MW_ (CO_2) = "44 01 g mol" "O"_2 " molecules = ?" "moles " CO_2 = (M_ (CO_2)) (MW_ (CO_2)) = ("220 mg" "1000 mg g
  • Question #6f7d1 - Socratic
    675N Here,the kinetic energy of the hammer head got totally converted to the work done in moving the nail through a distance of 10 mm or 0 01 m So, kinetic energy of the hammer during the strike was 1 2 m v^2=1 2×1 5×3^2=6 75J Now,if an average force of F had acted on the nail to move it by 0 01 m,then work done by the force will be (F×0 01)J(using W=F*s) So,we can equate both 6 75=F×0 01
  • Question #fbbce - Socratic
    The empirical formula is "C"_6"H"_7 > We can calculate the masses of "C" and "H" from the masses of their oxides "Mass of C" = 3 02 color(red)(cancel(color(black
  • Question #fe281 - Socratic
    4 ⋅ 12 01 = 48 04 g We now know that one mole of carbon contains 48 04 grams of carbon Next, we determine how many grams of carbon are in one mole of CO 1 ⋅ 12 01 = 12 01 g Now, we know that one mole of CO contains 12 01 grams of carbon With this information, we can determine how many moles of CO can be formed with the given mass of C
  • Question #315e6 - Socratic
    14 33"g of "H_2O Here is your balanced equation: C_6H_12O_6+ 6O_2rarr 6H_2O+6C0_2 We start Dimensional analysis (the factor-label method) by writing the given information over 1: (35"g of "CO_2) 1 We look up the molar mass of CO_2 and multiply by that factor so that it converts the units to moles: (35"g of "CO_2) 1(1"mol of "CO_2) (44 01"g of "CO_2) Please observe how the units cancel and we
  • Question #8b670 - Socratic
    The reaction produces 20 g of "NO" > We are given the amounts of two reactants, so this is a limiting reactant problem We know that we will need a balanced equation with masses, moles, and molar masses of the compounds involved Step 1 Gather all the information in one place with molar masses above the formulas and everything else below the formulas M_r:color(white)(mmmmll) 17 03color
  • Question #dbbcb - Socratic
    Avogadro's number shows the number of particles (atoms, ions etc ) in a mole of matter, while the molar mass shows the mass of 1 mole of a substance (in kg or g) If we divide the two numbers we get the number of particles (atoms, ions, etc ) in a mass unit (kg or g) of the substance N A m = [part mol ÷ kg mol = part mol × mol kg = part kg]
  • Question #1caee - Socratic
    "CO"_2 The question essentially wants you to figure out the molar mass, i e the mass of exactly 1 mole, of this compound Now, the important thing to keep in mind here is that 1 mole of a molecular substance contains 6 022 * 10^(23) molecules of that substance -> this is known as Avogadro's constant In other words, in order to have 1 mole of a molecular substance, you need to have a sample
  • Question #df236 - Socratic
    "27 g" The trick here is to look out for the phase change underwent by the ice sample More specifically, the ice will absorb heat from the hot water to go from solid at 0^@"C" to liquid at 0^@"C", then the liquid water at 0^@"C" will absorb heat to go to liquid at 15^@"C", the final temperature of the mixture All this heat will come from the hot water sample, hence the drop in temperature
