What does it mean if a solution is a "weak acid "? Strong acid? Give logical ph values for each
galina1969 [7]

Answer:

A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.

The average American is looking at their phone for 6.25 hours a day. How many hours will the average American spend on their pho
julia-pushkina [17]

Answer:

177253.125hrs

Explanation:

Given parameters:

  Number of hours spend per day on phone  = 6.25hrs

 Unknown:

Average hours pend by an average American if they lived for 77.7yrs

Solution:

Let us find the number of hours an average American spends on their phone per year;

    there are 365days in a year

 Number of hours  = 365 x 6.25  = 2,281.25hrs

Now, if they lived for 77.7yrs;

  They will spend  = 77.7 x 2,281.25 = 177253.125hrs

The pressure in a car tire is 198 kPa at 27°C. After a long drive, the pressure
AlekseyPX

Answer : The temperature of the air in the tire is, 341 K

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

P\propto T

or,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1 = initial pressure = 198 kPa

P_2 = final pressure = 225 kPa

T_1 = initial temperature = 27^oC=273+27=300K

T_2 = final temperature = ?

Now put all the given values in the above equation, we get:

\frac{198kPa}{300K}=\frac{225kPa}{T_2}

T_2=340.9K\approx 341K

Therefore, the temperature of the air in the tire is, 341 K

At 7 degrees Celsius the volume of gas is 49 liters. At the same pressure its volume is 74 mL at what temperature
Romashka-Z-Leto [24]
Charle's law gives the relationship between volume and temperature of gas.
It states that at constant pressure, volume of gas is directly proportional to temperature of gas.
V/T = k
where V - volume , T - temperature and k- constant 
\frac{V1}{T1} =  \frac{V2}{T2}
parameters for the first instance are on the left side of the equation and parameters for the second instance are on the right side of the equation 
T1 - 7 °C + 273 = 280 K
substituting these values in the equation 
\frac{49 mL}{280K} =  \frac{74 mL}{T}
T = 423 K
temperature in Celcius scale - 423 K - 273 = 150 °C
