Obre un objeto de masa m actúa una fuerza F que le provoca una aceleración de 4 m/s2. Si la fuerza aumentara 8 veces manteniendo constante la masa, ¿cuál sería el valor de la nueva aceleración en m/s2?

Write the chemical formula for a compound that is made of an element from group 1 and an element from group 17

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

How is the way a mixture is combined different from how a compound is combined?
