Answer:
d. The particles of matter are arranged
in different ways for the different
states.
Explanation:
when you hear kinetic think hot or cold
example
water when its hot its a gas and looks different under a microscope
water when its cold its ice and looks different under a microscope
Answer:
The answer to your question is molality = 0.34
Explanation:
Data
mass of NaBr = 14.57 g
mass of water = 415 g.
molality = ?
Process
1.- Calculate the molar mass of NaBr
NaBr = 23 + 80 = 103 g
2.- Calculate the moles of NaBr
103 g of NaBr ------------------ 1 mol
14.57 g of NaBr --------------- x
x = (14.57 x 1) / 103
x = 14.57 / 103
x = 0.141 moles
3.- Calculate the molality
molality = moles / volume
-Substitution
molality = 0.141 / .415
-Result
molality = 0.34
2 KMnO4 (aq) + 5 H2O2 (aq) + 3 H2SO4 (aq) → 5 O2 (g) + 2 MnSO4 (aq) + K2SO4 (aq) + 8 H2O (l)
Answer :]
to convert from g NaOH to mol NaOH. = 1.48 g NaOH are needed to neutralize the acid.
It definitely isn't c so I think u should go with choice a
