Hi! i can't help with everything but here are some of the answers:

- the 7 colors of the visible light spectrum are Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
- red has the longest wavelength and violet has the shortest
- when white light enters a prism, it gets separated into the 7 colors of the visible light spectrum in a process called "dispersion"

hope this helps!

aivan3 [116]

Answer:

  • <u>355 kPa</u>

Explanation:

The ideal gases follow Boyle's law: at constant temperature pressure and volume are inversely related:

       PV=constant

       P_1V_1=P_2V_2

       P_2=\dfrac{P_1V_1}{V_2}

Subsituting and computing:

     P_2=\dfrac{1.643L\times 128kPa}{0.593L}\approx355kPa

goldfiish [28.3K]

Answer:6.94

Explanation:

Molar mass of CaCO3=40+12+16×3

=40+12+48=100g/mol

Moles=mass of substance/molar mass

=97mg/100g=0.097/100=0.00097moles/L.

PH=-log[CaCo3]=-log(0.00097)=6.94

P.s it's log to base e
