How do i find the q of a rxn if the density of water is 1.0g/ml and the cs is 4.18 j/g*c?
i have 50ml of 1m hcl and 50ml of 1m naoh, and the change in temperature was 6.4c.
i got -2675.2j, but i have no idea if that seems reasonable. the equation is: q of rxn = (-m of soln)(cs)(change in temp of soln).

This graph gives information on changes in sea ice extent in the arctic ocean over a 30-year span. the overall trend shows in the ice extent. to address the trend, scientists need to ask themselves, one direct consequence of the trend is that

If blood contains 150g of hemoglobin per liter of blood, how much hemoglobin would be contained in 10 ml of blood

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
