Answer:
acid precipitation is an agent of
Explanation:
Answer:
Approximately 56.8 liters.
Assumption: this gas is an ideal gas, and this change in temperature is an isobaric process.
Explanation:
Assume that the gas here acts like an ideal gas. Assume that this process is isobaric (in other words, pressure on the gas stays the same.) By Charles's Law, the volume of an ideal gas is proportional to its absolute temperature when its pressure is constant. In other words
,
where
is the final volume,
is the initial volume,
is the final temperature in degrees Kelvins.
is the initial temperature in degrees Kelvins.
Convert the temperatures to degrees Kelvins:
.
.
Apply Charles's Law to find the new volume of this gas:
.
Explanation:
Carbon dioxide isn't a polar molecule because
same nature of charge appears in opposite direction which cancel each other. So, carbon dioxide is non-polar molecule.
V = 500ml = 0,5 l
c = 0,75 M
c = n/V
n = c × V
n = 0,75 × 0,5 = 0,375[mol]
M NaCl = 58,5 g/mol
1 mol ------- 58,5 g
0,375 mol ----- x g
x = 0,375 mol × 58,5 g / 1 mol = 21,94 g
Answer: In this solution there are 21,94 g of sodium chloride.
