When 25.0 ml of 0.500 m h2so4 is added to 25.00 mk of 1.00 m koh in a coffee-cup calorimeter at 23.50◦ c, the temperature rises to 30.17◦ c. calculate dhrxn for this reaction. (assume that the density of water of and specific heat capacity of the solution are the same as for pure water). ( –55.8 kj/mol koh, –112 kj/mol h2so4)

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

Which set of characteristics best describes igneous rock? a) largest type of rock, made of organic matter, hardest type of rock b) least abundant type of rock, made of other rocks, made mostly of minerals c) found on all continents, contains wavy bands of stripes, contains fossils d) most abundant type in earth's crust, made of magma/lava, contains no fossils

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.
