Answer:

14

Explanation:

70g/(35mL-30mL)=14g/mL

Andrews [41]2 years ago

Answer:

14 g/mL

Explanation:

The formula to find the density is p=m/v.

The mass is 70 grams. The volume is 5 due the the fact that we subtracted the final volume to the initial volume. Then we divide 70 by 5 and you'll get 14 as your answer.

I hope this helps in the future! Have a great day.

Equation is set below:

p= m/v

p=70/5

p= 14

a skateboarder wants to skate down the ramp at a skate park he will want the forces acting on him to be
kvasek [131]

Answer:

increase

Explanation:

At the skate park when a skateboarder wants to skate down a ramp, the skate boarder wishes to move faster and with speed so that it help him to skate more time. This can only be achieved if the all the forces acting on him will increase as he skates down the ramp without much of the frictional force acting on the wheels of the skate board. The less friction force acts on the wheel, the more he can skate with more speed.

Thus, the skateboarder wants the force to be increase that is acting on him.

¿Qué hecho indujo a Heisenberg a establecer el principio de incertidumbre?
yaroslaw [1]

Answer:

Here's what I find  

Explanation:

Heisenberg observed that if we want to locate a moving electron, we must bounce photons off it.

However, this makes it recoil. By the time the photon returns to our eye, the electron will no longer be in the same place.

He concluded that there is a limit to the precision with which we can simultaneously measure the position and speed (momentum) of a particle.

The more precisely we know the electron's speed, the less precisely we know its position and vice versa.

The uncertainty in the product of the two values cannot be less than a fixed small number.

Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H
GalinKa [24]
The balanced chemical reaction is:

N2 + 3H2 = 2NH3

We are given the amount of hydrogen gas to be used in the reaction. This will be the starting point of the calculations.

24.0 mol H2 (2 mol NH3 / 3 mol H2 ) = 16 mol NH3

Therefore, ammonia produced from the reaction given is 16 moles.
