<h3>Molar mass of Ammonia:-</h3>

\\ \sf\longmapsto NH_3

\\ \sf\longmapsto 14u+3(1u)

\\ \sf\longmapsto 14u+3u

\\ \sf\longmapsto 17u

\\ \sf\longmapsto 17g/mol

Moles of Ammonia:-

\boxed{\sf No\:of\:moles =\dfrac{Given\:mass}{Molar\:mass}}

\\ \sf\longmapsto No\:of\:moles=\dfrac{17}{17}

\\ \sf\longmapsto No\;of\:moles=1mol

  • Volume of solution=0.50L

We know

\boxed{\sf Molarity=\dfrac{Moles\:of\:solute}{Volume\:of\: Solution\:in\:L}}

\\ \sf\longmapsto Molarity=\dfrac{1}{0.50}

\\ \sf\longmapsto Molarity=2M

Explanation:

Because molarity is mol/L, we'll have to convert 17g to mol.

After obtaining the mol, we'll divide that by the volume to obtain Molarity.

Answer:

Decrease occur in the amount and flow of water bodies.

Explanation:

There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.

Can someone help me by giving me the formula of determining the amount of energy used in a reaction?
Vlada [557]
Q=mc(deltaT)
Q is the amount of energy which you are looking for
M is the mass which you can find
C is the specific heat of water which is 4.18 J/gC
DeltaT is the change in temperature which you can find.

To find the mass, first you must know that the density of water is 1g/mL, meaning that 200 mL has a mass of 200 g. This means that to find the total mass (m in the equation) all you need to do is add the mass of water and NaOH.

200 g + 2.535 g=202.535 g.

To find deltaT you would need to take the final temperature minus the initial temperature.

27.8C-24.2C=3.6C

Then these values can be substituted into the equation:

q=(202.635g)(4.18J/gC)(3.6C)
Q=3049.25 J

Technically this should be rounded off to 1 significant figure (200 mL only had 1), but ignoring signficiant figure rules this should be correct. Also, sometimes other units like calories or kJ may be asked for, meaning that a conversion or alternate c value would be used.

liq [111]
<h2>Answer</h2>

The volume will be<u> 50 L</u>

<h2>Explanation</h2>

From Kelvin Law of Temperature, we know that

V_{1} T_{1} =V_{2} T_{2}

We know that

V_{1} = 200 L

T_1 = 100 K

T_2= 400 K

So,

V_{2} = V_{1} T_{1}/T_{2}

V_{2} = 200*100/400

V_{2} = 50 L

The answer of the givern question is 50L

What causes pressure inside an inflated soccer ball?
ioda

Answer:

A

Explanation:

Ball bounces because of the difference in the air pressure on the outside of the ball, and opposite the point of impact, and the pressure inside of the ball. This means that the inside of the ball now has less space to contain the air molecules contained inside the ball, increasing the pressure inside the ball.
