PLEASE HELP QUICK AS POSSIBLE How much heat is required for 25.0g of water to rise in temperature from 35.0 to 75.0°C?

Formulas~
*q = mcT (temp change)
*q = mH (phase change)

How are elements arranged in a periodic table

Which of the following describes a compound? (hint: carbon and oxygen bo a. a piece of pure carbon, containing only carbon atoms b. oxygen gas surrounding a solid piece of carbon c. a substance made of two oxygen atoms for each carbon atom carbon and oxygen atoms mixed without being bonded together

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
