Makes it easier to move an object. It takes less force to move an object in an upward direction on an inclined plane than it does to lift the object straight up. ... However, the inclined plane reduces the force needed to do the work. I think u can use this answer

Helga [31]

Answer: Membrane Protiens

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

Calculate the volume in milliliters of a 2.09 M silver nitrate solution that contains 400 g of silver nitrate AgNO3. Round your

Liula [17]

Answer: The volume of solution is 1.13 L

Explanation:

To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}$

We are given:

Molarity of solution = 2.09 M

Given mass of silver nitrate = 400. g

Molar mass of silver nitrate = 170 g/mol

Putting values in above equation, we get:

$2.09M=\frac{400}{170\times \text{Volume of solution}}\\\\\text{Volume of solution}=\frac{400}{170\times 2.09}=1.13L$

Hence, the volume of solution is 1.13 L

What would be the volume in liters of an 2.45 liter sample of gas at 594 °C

Ber [7]

Answer:

$V_2= 1.19L$

Explanation:

Hello there!

In this case, since the STP conditions are defined by 1 atm (101.3 kPa) and 273 K, it is possible for us to use the combined gas law for this problem as we are given variable pressure, temperature and volume:

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

In such a way, solving for V2 as the final volume, we obtain:

$V_2=\frac{P_1V_1T_2}{P_2T_1} =\frac{156kPa*2.45L*273.15K}{101.3kPa*(594+273)K}\\\\V_2= 1.19L$

Regards!
