Explanation:
According to the ideal gas equation, PV = nRT.
where, P = pressure, V = volume
n = no. of moles, R = gas constant
T = temperature
Also, density is equal to mass divided by volume. And, no. of moles equals mass divided by molar mass.
Therefore, then formula for ideal gas could also be as follows.
P = ![\frac{mass}{volume \times molar mass} \times RT](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bvolume%20%5Ctimes%20molar%20mass%7D%20%5Ctimes%20RT)
or, P = ![\frac{density}{\text{molar mass}} \times RT](https://tex.z-dn.net/?f=%5Cfrac%7Bdensity%7D%7B%5Ctext%7Bmolar%20mass%7D%7D%20%5Ctimes%20RT)
Since, density is given as 0.789 g/ml which is also equal to 789 g/L (as 1000 mL = 1 L). Hence, putting the given values into the above formula as follows.
P = ![\frac{density}{\text{molar mass}} \times RT](https://tex.z-dn.net/?f=%5Cfrac%7Bdensity%7D%7B%5Ctext%7Bmolar%20mass%7D%7D%20%5Ctimes%20RT)
= ![\frac{789 g/l}{46.06 g/mol} \times 0.0821 L atm/mol K \times 373 K](https://tex.z-dn.net/?f=%5Cfrac%7B789%20g%2Fl%7D%7B46.06%20g%2Fmol%7D%20%5Ctimes%200.0821%20L%20atm%2Fmol%20K%20%5Ctimes%20373%20K)
= 525 atm
As two-liter soft drink bottle can withstand a pressure of 5 atm and the value of calculated pressure is 525 atm which is much greater than 5 atm.
Therefore, the soft drink bottle will obviously explode.
The one that will dissolve most quickly is : D. a tablespoon of ultrafine sugar
Unlike any other type of sugar, ultrafine sugar tend to have smaller crystal size. Which means that this substance will dissolve easier if it put into liquid such as tea or water
hope this helps

Answer:
It is widely believed that Buddhism entered China via the Silk Road under the Han Dynasty. After trade and travel was established with the Yuezhi, who by that time were forced southward toward India, Yuezhi monks began to travel with the merchant caravans; preaching their religion along the Silk Road.
Explanation:
i got this from google
The correct answer is a. This is because the pH of a solution is defined as -log10(concentration of H+ ions). An inverse logarithmic scale such as this means that a solution with a lower concentration of H+ ions will have a higher pH than one with a higher concentration. Therefore we know that the pH of the second sample will be higher than the first.
Since the logarithmic scale has the base 10, a change by 1 on the scale is a consequence of multiplication/division of the H+ concentration by a factor of 10. As the scale is inverse, this means that a decrease of concentration by factor 1000 is equivalent to increasing the pH by (1000/10) = 3.
