Answer:

2HgO --> 2Hg + O2 is a decomposition reaction, in which mercury oxide is decomposed into the element mercury and oxygen gas. A decomposition reaction is one in which a more complex substance is broken down into its simpler components.

Hope this helps!

If a car is traveling 100 km/h and comes to a stop in 3 minutes,what is acceleration of a passenger who is using vehicle restrai

Rama09 [41]

We are given –

Final velocity of car is, v= 0
Initial velocity of car is, u= 100 km/hr
Time taken, t is = 3 minutes or 180 sec

Here–

$\qquad$ $\pink{\bf \longrightarrow Initial\: velocity = 100 \:km/hr}$

$\qquad$ $\sf \longrightarrow Initial\: velocity = \dfrac{ 100 \times 1000}{3600} \:m/s$

$\qquad$ $\pink{ \bf \longrightarrow Initial\: velocity = 27.78\: m/s}$

Now –

$\qquad$ ____________________________

$\qquad$ $\purple{\bf \longrightarrow Acceleration = \dfrac{Final\: Velocity -Initial \:Velocity }{Time}}$

$\qquad$ $\purple{\bf \longrightarrow Acceleration = \dfrac{v -u}{t}}$

$\qquad$ $\sf \longrightarrow Acceleration = \dfrac{(0- 27.78)}{1800}$

$\qquad$ $\sf \longrightarrow Acceleration =\cancel{ \dfrac{- 27.78}{1800}}$

$\qquad$ $\purple{\bf \longrightarrow Acceleration = -0.15 \: m/s^2}$

Sladkaya [172]

M1 = 17.45 M

M2 = 0.83 M

V2 = 250 ml

M1. V1= M2. V2

V1 = (M2. V2)/M1 = (0.83× 250)/ 17.45= 11.89 ml

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water . What mass of water is produced by the reaction of

Kay [80]

Full Question:

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water. What mass of water is produced by the reaction of 7.7g of ammonia?

Be sure your answer has the correct number of significant digits.

Answer:

12.23g ≈ 12g (2 s.f)

Explanation:

Ammonia chemically reacts with oxygen gas to produce nitric oxide and water. The balanced chemical reaction is given as:

4 NH3 + 5 O2 -------> 4 NO + 6 H2O

From the reaction;

4 mole of ammonia reacts to produce 6 moles of water

From the question;

Moles = mass / molar mass

From the question;

moles of ammonia = mass / molar mass = 7.7 / 17 = 0.4529moles

Number of moles of water produced;

4 = 6

0.4529 = x

x = (0.4529 * 6 ) / 4

x = 0.67935moles

Mass of water = moles * molar mass = 0.67935 * 18 = 12.23g ≈ 12g (2 s.f)
