Answer:
Light changes speed in a glass of water.
Explanation:
Answer:
In a closed system the vapor pressure and the measured pressure of a gas increases.
Explanation:
as the pressure of the liquid increases the measured pressures also increases with a given temperature.
1. Calculate no. of moles by dividing mass given/molar mass
= 0.250 /283.8
2. Now multiply no. of moles with avogadro's no.
3. The answer indicates no. of total atoms..
M
350 mL = 0.350 L
245.0g H2SO4 / 98.08 g/mol H2SO4
= 2.5 mol H2SO4
2.5 mol H2SO4 / 0.350 L = 7.14 M
Answer:
Explanation:
Here in Calcium Chloride ionic bond is present in between calcium and chlorine atoms. As we know according to Octet rule calcium have two excess atoms and for matching nearest noble gas electronic configuration. It donate two electrons to gain more stability and form 
, while chlorine is deficient from one electron to meet nearest noble gas electronic configuration therefore two chlorine atoms accept excess electron from calcium individually and form two
ions.
Hence aqueous solution of calcium chloride breaks the ionic bond pairing in one and twoions:
