Avogadros Law if pressure is the result of collision, molecules colliding with the wall of the container and every time they collide they exert a force. pressure is the result of the force and area. if we add more gas particles you are going to see more collisions with the wall of container the gas particles will exert a greater over the same exact area. they have a directly proportional relationship. Pressure and volume, pressure=force/area, if we have a container with the same number of particles but of different particles, the smaller volume containers will have smaller area and more collision increasing pressure so they have an inversely proportional relationship. Pressure and temperature, pressure=Force/area force is going to change not the area, when we heat up the molecules up they end up moving faster colliding with the walls of the container more often exerting a greater force. now Volume and temperature, if we heat the gas particles, they move more rapidly gas expands!.

Answer:

Each of these organelles performs a specific function critical to the cell's survival. For example, biochemical reactions in a cell's mitochondria transfer energy from fatty acids and pyruvate molecules into an energy-rich molecule called adenosine triphosphate (ATP).

a 25 ml volume of a sodium hydroxide solution requires 19.6 mL of a 0.189 M HCl acid for neutralization. A 10 mL volume of phosp

Drupady [299]

Answer: 0.172 M

Explanation:

a) To calculate theconcentration of base, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $HCl$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=1\\M_1=0.189M\\V_1=19.6mL\\n_2=1\\M_2=?\\V_2=25mL$

Putting values in above equation, we get:

$1\times 0.189\times 19.6=1\times M_2\times 25\\\\M_2=0.148$

b) To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $H_3PO_4$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=3\\M_1=?\\V_1=10mL\\n_2=1\\M_2=0.148\\V_2=34.9mL$

Putting values in above equation, we get:

$3\times M_1\times 10=1\times 0.148\times 34.9\\\\M_1=0.172M$

The concentration of the phosphoric acid solution is 1.172 M

luminous objects such as flashlights emit light that we can see. how do we see an object that isnt luminous?

Pavel [41]

<span>In order for us to see an object that is non-luminous, it must reflect some of the light it receives from a luminous source, such as the Sun. Most of the objects we see, such as cars, clouds or even the Moon, are not luminous; it is just that they reflect sunlight</span>
