oh ok.. so i multiply my sb by 2 and s by 3 .. (their masses and then add them together like normally)

An Ore contains 19.6 %... Question: An ore contains 19.6% of the mineral stibnite, Sb2S3, which is a source of the element Sb. how much ore must be processed in order to obtain 47.0kg of Sb?My Work: (47000g Sb)((153.825g Sb2S3/ 2 (121.76 g Sb)) (100g ore/19.6g Sb2S3) which equals...

so you always use the smallest one correct?

ok so this may sound really dumb but i need to refresh my memory on this so here is the question 6.941+63.996+35.45 = 106.387 how do i know how many sig figs to round too with this?

Homework Statement light with a wavelength of 520 nm abd 630 nm passes through a diffraction grating that contains 6000 lines/cm. a) sketch a diagram of the image produced from m=0 to m=2, label the order of each fringe b) calculate the angles for the first and second order maxima that...

1. Homework Statement Two different single slits are used in an experiment involving one source of monochromatic light. With slit 1 in place, the first dark fringe is observed at an angle of 45 degrees. With slit 2, the first dark fringe is observed at an angle of 55 degrees. a)Which slit is...

A single slit is illuminated with a helium-neon laser whose wavelength is 633 nm. If the slit width is 2.2 x 10 e-5 m, calculate the position of the third maximum in degrees 2. Homework Equations Sin Theta(m) = (m + 0.5) Lambda/w 3. The Attempt at a Solution Sin Theta(3) = (3 +...

Calculate the potential difference that would have to be maintained across the plates of a parallel plate apparatus, if the plates were 1.2cm spat, to create an elecric field strength of 1.5x10^4 N/C. i have no idea how to do this! someone please help

Electric, Gravitatinal, and magnetic! which two of the three types of field discussed in this lesson were most similar> provide supporting evidence. there are electric, gravitational and magnetic.. im guessing its electric and magnetic.. but I am not sure!

could you help me with this! which two of the three types of field discussed in this lesson were most similar> provide supporting evidence. there are electric, gravitational and magnetic.. im guessing its electric and magnetic

thanks!

Acceleration with Fe2+ ion and Fe3+ ion help! A sample of two different iron ions, Fe^2+ and Fe^3+, are accelerated by the same potential and sent through the uniform magnetic field of a mass spectrometer. a)Which ions moves faster after being accelerated. Justify with relevant equations...

describe how an electric bell operates (HINT: the make break contact dose not move; the hammer, however, moves bath and forth very quickly as it rings the bell) my solution An electric bell is a mechanical bell that functions by means of an electromagnet. When an electric current is...
