I haven't done any science assignments of the unit we are learning and I have no clue at all what it's all about...what is activ

IceJOKER [234]

Active Transport: Moves ions and molecules from lower to higher concentrations using energy.

Passive Transport: Move ions and molecules from high to lower concentrations without using energy.

The main difference is one uses ATP (energy) and the other does not.

Law of action-reaction

anzhelika [568]

Answer:

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Taking into account the definition of density, the density of the sample is 0.5 $\frac{g}{mL}$ .

It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density allows you to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

In this case, you know:

mass= 6 g
volume= 12 mL

Then, replacing in the definition of density:

$density=\frac{6 g}{12 mL}$

Solving:

<u><em>density= 0.5 </em></u> $\frac{g}{mL}$ <u><em /></u>

Finally, the density of the sample is 0.5 $\frac{g}{mL}$ .

A gas sample at stp contains 1.15 g oxygen gas and 1.55 g nitrogen gas.what is the volume of the gas sample?

ss7ja [257]

O2=32 g/ mol
1.15/32=0.035
N2=28 g/mol
1.55/28=0.055
in STP every 22.4 litters is 1 mol
