______ is the type of heat that roasts the marshmallows.

Consider the reaction N2(g) + 3H2(g) → 2NH3(g) Suppose that at a particular moment during the reaction, molecular hydrogen is re

rosijanka [135]

Answer:

The solution to the question is as follows

(a) The rate of ammonia formation = 0.061 M/s

(b) the rate of N₂ consumption = 0.0303 M/s

Explanation:

(a) To solve the question we note that the reaction consists of one mole of N₂ combining with three moles of H₂ to form 2 moles of NH₃

N₂(g) + 3H₂(g) → 2NH₃(g)

The rate of reaction of molecular hydrogen = 0.091 M/s, hence we have

3 moles of H₂ reacts to form 2 moles of NH₃, therefore

0.091 M of H₂ will react to form 2/3 × 0.091 M or 0.061 M of NH₃

Hence the rate of ammonia formation is 0.061 M/s

(b) From the reaction equation we have 3 moles of H₂ and one mole of N₂ being consumed at the same time hence

0.091 M of H₂ is consumed simultaneously with 1/3 × 0.091 M or 0.0303 M of N₂

Therefore the rate of consumption of N₂ = 0.0303 M/s

You leave for school late when you are pulled over by a police officer for speeding. He clocks you at 52 mi/hr . What is your sp

yawa3891 [41]

Answer:

Explanation:

The maximum speed limit in Prince Edward Island

unless otherwise posted is 80 kilometres per hour

(km/h). The basic speed limits are:

• 40 km/h (25 mph) in most municipalities

(municipalities may establish the maximum

speed limit within their boundaries);

• 50 km/h (30 mph) in urban areas;

• 60 km/h (40 mph) in school zones designated as

such by the erection of signs at the entrance and

the exit, between 8 a.m. and 5 p.m. when

children are present on or near the highway on

school days;

• 80 km/h (50 mph) on most provincial highways;

and

• 90 km/h (55 mph) on the TransCanada and

other designated highways.

Posted speed limits indicate the maximum safe

speed under favourable driving conditions.

A burner on a stove produces temperature. thermal energy. hotness. fire energy.

Aleksandr [31]

Question:

The options are;

a. Temperature

b. Thermal Energy

c. Hotness

d. Fire Energy

Answer:

The correct option is;

b. Thermal energy

Explanation:

A burner on a stove produces thermal energy which is used to raise the temperature of the metal container (kettle, pot or pans) in which items are placed for heating.

Thermal energy is the internal energy of the system given off as heat which when transferred from one body to another causes the temperature of the receiving body to rise. Thermal energy in a burner is given off when the gaseous fuel reacts or burns in the presence of or with oxygen to produce carbon dioxide and water vapor in an exothermic reaction.

4C + 5H₂ + 13/2O₂ (-125 kJ) → C₄H₁₀ + O₂ → CO₂ + H₂O (-2877 kJ).
