How many grams of sugar must be dissolved in 150 ML of water to make a solution that has a concern traction of .6 g/ml
grandymaker [24]

Hey there!:

Density = 0.6 g/mL

Volume = 150 mL

Mass = ?

therefore:

D = m / V

0.6 = m / 150

m = 0.6 x 150

m = 90.0 g of sugar

Hope this helps!

13. What is the photon energy associated with visible light with a wavelength of 4.25x10^-7 m?
4vir4ik [10]

\\ \sf\bull\longmapsto E=hv

\\ \sf\bull\longmapsto E=\dfrac{hc}{\lambda}

\\ \sf\bull\longmapsto E=\dfrac{6.626\times 10^{-34}Js\times 3\times 10^8ms^{-1}}{4.25\times 10^{-7}m}

\\ \sf\bull\longmapsto E=\dfrac{19.878\times 10^{-26}Jm}{4.25\times 10^{-7}m}

\\ \sf\bull\longmapsto E=4.677\times 10^{-19}J

\\ \sf\bull\longmapsto E=4677\times 10^{-16}J

\\ \sf\bull\longmapsto E=4677eV

Can you help me on this since im struggling on this since day 1
emmasim [6.3K]
Of Ok here is what I am thinking.

Simple replacement means when one element or compound moves out of another element and is replaced by this compound.

For example if you have A+BC ----- AC + B

Most of the time the one which is replaced is found on the right and the left one is going be only one element or compound.

Double replacement means when the two compounds exchange the positive and negative ions. Ok let see this example:


AB+ CD------- AD+ BC
this means if A have  + sign and D has - sign they will share to form new compound the same is true for DC. Don't forget that all compounds are formed from positive and negative ions. 

                                 QUESTIONS
CUSO4 + NA2S---- CUS + Naso4[ double replacement]
KBR +Pb[CLO3]2------K[clo3]2 +PbBr [ double replacement]
I do not  think these questions can be single replacement.
I hope this may helps you.
