Which formulas might be used to find the velocity based on a position-time graph? check all that apply.

y2 – y1
d/t
x2 – x1
y2 – y1/x2 – x1
? x/t

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
