Answer:

83.99 KC1 1.

Explanation:

What is the total number of grams of KCl (formula 2.200M=xmol - 200 mdr o mass = 74.6) in 1.00 liter of 0.200 molar solution? 3941+355 74.69 ml atonal 1.13 mol 174.6g) = 83.99 KC1 1.

An 8.0 L sample of neon gas at 300. K exerts a pressure of 900. kPa. If the gas is compressed to 2.0 L and the temperature is ra
svetoff [14.1K]

Answer:

7200 kPa

Explanation:

Applying,

PV/T = P'V'/T'................ Equation 1

Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas

Make P' the subject of the equation

P' = PVT'/V'T.............. Equation 2

Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K

Substitute these values into equation 2

P' = (900×8×600)/(2×300)

P' = 7200 kPa

Two workers used a force of 100 N to move a sofa 4 meters in 2 seconds how much power
r-ruslan [8.4K]

Answer:

200 watts

Explanation:

First we have to find total work:

W =F(d)

W = 400J

Then plug that answer into the Power formula.

P = W/(t_f-t-i)

P = 400/2s

P = 200 W

What is one characteristic of the groundwater that forms caves? A. It is very hot. B. It is very cold. C. It is slightly acidic.
QveST [7]

Answer: Groundwater that forms caves because it is slightly acidic.

Explanation:

The water under the ground present inside the cracks and spaces in sand, soil and rocks is called ground water.

When ground water moves through the soil it results in the formation of acid. Further, this acid helps minerals to get dissolve. These minerals get deposited on other places as well.

This process of deposition and erosion helps in the formation of caves.

Thus, it can be concluded that groundwater that forms caves because it is slightly acidic.
