A. a higher boiling point and a lower freezing point
Explanation:
hope this helps :)
Answer:
molar mass is 158g and the mass of 5moles is 790g
Explanation:
this is becasuse i added the atomic mass of each of the elements in the compound and also taking note of their subscript.the i multiply the molarmass by 5 for 5moles of the compound
<u>Answer:</u> The number of moles of gas in bicycle tire is 0.210 moles
<u>Explanation:</u>
To calculate the moles of gas, we use the equation given by ideal gas which follows:

where,
P = pressure of the gas = 737 torr
V = Volume of the gas = 5.30 L
T = Temperature of the gas = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
R = Gas constant = 
n = number of moles of gas = ?
Putting values in above equation, we get:

Hence, the number of moles of gas in bicycle tire is 0.210 moles
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.
65 x V1 = 2 x 200 L
V1 = 6.15 L
D) basic ions contain some H+ ions
