Calculate the ΔHrxn for the following
2NOCl(g)→N2(g)+O2(g)+Cl2(g)
Given:
12N2(g)+12O2(g)→NO(g)
ΔH = 89.32
NO(g)+12Cl2→NOCl(g)
ΔH = -30.39
Answer:
2 NO (g) → N2 (g) + O2 (g)
2 NOCl (g) → 2 NO (g) + Cl2 (g)
____________________________
2NOCl (g) ⟶ N2 (g) + O2 (g) + Cl2 (g)
ΔH = [90.3 kJ x 2 x -1] + [-38.6 kJ x -1 x 2] = -103.4 kJ
The ΔH for the reaction is -103.4 kJ

Which example describes an inherited trait that cannot be determined by observing an individual?
What is the difference between a meteor and a meteorite?
Answer:
meteorites are inside Earth's atmosphere on the ground
meteors are outside Earth's atmosphere
Explanation:
When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.

When a pot of water is boiling on the stove it has increased....?
1) Potential Energy
2) Elastic Energy
3) Thermal Energy
4) Kinetic Energy
Answer:
The correct answer would be "3) Thermal Energy"
Explanation:
The thermal energy comes from heat and goes back out as condensation.

the answer is C
Explanation:
If you put water in a glass it takes the shape, right? It doesnt just sit on top refusing to go in. Its the same with gas. If you can manage to capture gas it will form to the glass instead of staying in the same state.
Hope I helped, have a good one :)

Explanation:
A ball is rolled in a straight line on a smooth frictionless surface. According to Newton's law of inertia, the ball will –
A) continue to roll in a straight line and eventually slow to a stop.
B) continue to roll in a straight line and increase, then decrease in speed.
C) continue to roll in a straight line and gradually increase in speed.
D) continue to roll in a straight line and remain at a constant speed.
Answer:
A
Explanation:
The ground is frictionless, which means that the ball won' slow down, until it is out of kinetic energy.
According to Newtons' law of inertia, a body keeps in a state of rest or moving until and unless an external force acting on it. If it continues to moving then it moves in a straight line with a constant speed.
What is inertia?Inertia of a massive body is the tendency to continue in state at which it exists now (rest/moving) until an external force acts on it.
Newtons law of motion says the same that a body at rest tends to continue in rest and a body if moving tends to continue its moving. This is one of the basic law in three law of motion by Newton.
Law of inertia is called the first law of motion by Newton and the second law states the relationship between mass and acceleration and the third law states that every action is accompanied by an opposing reaction.
According to law of inertia for a body at moving continuous to move in a frictionless path in a constant speed. The consistency in speed can only be maintained if the path is frictionless.
Hence, option D is correct. The ball will roll in a straight line with continuous speed.

A student lists three temperature measurements: 200°F, 200°C, and 200 K. Of the three measurements, 200 K is the highest temperature. true or false
Answer:
pointa
Explanation:
Answer:
False
Explanation:
Given temperature values;
200°F , 200°C and 200K
To solve this problem, convert all the given values to the same unit.
Let us choose kelvin as our standard here;
°F → °C → K
200°F;
(°F − 32) × [tex]\frac{5}{9}[/tex] = °C
Insert the parameters;
(200 - 32) x [tex]\frac{5}{9}[/tex] = 93.3°C
So;
°K = 273 + °C = 273 + 93.3 = 366.3K
For 200°C;
°K = 273 + °C = 273 + 200 = 473K
The highest temperature is 200°C

Gerald is fishing. He uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish. Which statement accurately describes the densities of these two items?
1)The bobber and lure are more dense than the water.
2)The bobber and lure are less dense than the water.
3) The bobber is more dense than the water, and the lure is less dense than the water.
4)The bobber is less dense than the water, and the lure is more dense than the water.
Answer:
4
Explanation:
in order for the bobber to float,it must be less dense, and for the line to sink, it must be more dense.
Answer:
number 4
Explanation:
sorry if wrong
why does gold sink and wood float when they have similar volumes?

why does gold sink and wood float when they have similar volumes? Include what is happening with the mass size and arrangement of atoms
explain density in your own words
gold sinks and wood floats because____
Answer:
Gold has a density higher than water so it sinks. Wood has a density lower than water so it floats.
Explanation:
Wood has less packed particles compared to gold. Gold had more packed molecules.
Answer:
Solids are not the only substances that have density. Water and air have density that changes too. Density plays a key role in determining whether objects will sink or float in fluids and gases. Gold sinks in water because gold is denser than water, and pine floats in water because pine is less dense than water.The particles in wood are not so closely packed. There is more space in between the particles and fibres, which gives wood its low density.
