Hey I'm Chloe can you Help me, Thank you :)
How does photosynthesis use solar energy?

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

How does the viscosity of magma change as magma cools?

Iwould appreciate if someone could me.
