Silver bromide is used to coat ordinary black-and-white photographic film, while high-speed film uses silver iodide. (a) when 50.0 ml of 5.0 g/l agno3 is added to a coffee-cup calorimeter containing 50.0 ml of 5.0 g/l nal, with both solutions at 25∘c what mass of agl forms? (b) find δh∘rxn (c) what is δ tsoln (assume the volumes are additive and the solution has the density and specific heat capacity of water)?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

they are all solids.
