Answer:

2H2(g) + O2(g) ------------------> 2H2O(g)

Explanation:

Basically, the reaction of hydrogen and oxygen is a type of combination reaction and forms steam as its end product. The pure hydrogen burns with a blue flame with oxygen. Industrially, where the combination of hydrogen and oxygen is needed to undergo rapidly, platinum catalyst is introduced. This reaction gives steam rapidly. Platinum speeds up the rate of the reaction of hydrogen and oxygen gases.

What is the density of a piece of metal in g/cm3 if its mass is determined to be 42.20 g and it is in the shape of a cube, with

maria [59]

It's a cube so the volume = edge^3
Volume = 2.5^3 cm^3 = 15.625 cm^3

density = mass / volume = 42.20 / 15.625 = 2.70 You have 3 places of accuracy.

density of object = 2.70 grams / cm^3 <<<<=== answer.

Atmospheric pressure decreases as altitude increases. in other words, there is more air pushing down on you at sea level, and th

LuckyWell [14K]

Boiling point is the temperature at which vapour pressure equals atmospheric pressure.

As, we move at higher altitudes, atmospheric pressure decreases. Hence, temperature to reach the boiling point will decrease.

Further, boiling point is higher for longer chain compounds. Hence,<span> octane (C8H18) and octanol (C8H17OH) will have higher boiling point as compared to hexane (C6H14). Further, intermolecular forces of interaction are more stronger in octanol, due to presence of OH group, as compared to octane.

Hence, boiling points will be in following order:
Octanol > Octane > Hexane

Thus, hexane will boil first, followed by octane and lastly octanol.</span>

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type. ___P4 + ___O2 ⟶ _

Serhud [2]

According to the conversation of mass, mass cannot be created or destroyed. This means whatever is done to one side, must be done to the other.

There are 4 Phosphorus atoms on the left, there must be 4 on the right. To do this, you must multiply the P2O3 by 2 to get 4 Phosphorus atoms and 6 Oxygen atoms. Now to balance the Oxygen atoms, you must multiply the oxygen atoms on the left by 3.

1 P4 + 3 O2 —-> 2 P2O3

Lastly, this equation type is synthesis (combination) because two reactants are becoming a single product.

Anh measured the temperature of a pond near his house. Before he left for school, the water in the pond was 18 degrees celsius.

Hitman42 [59]

As the temperature increases, B) the molecules started moving faster.

Explanation:

The temperature of a substance is a measure of the average kinetic energy of the particles in a substance. In particular, it can be found that the temperature is directly proportional to the average kinetic energy of the particles:

$T\propto KE$

The kinetic energy of a particle is given by

$KE=\frac{1}{2}mv^2$

where

m is the mass of the particle

v is its speed

This means that the higher the temperature of a substance, the greater the speed of the particles in the substance.

Therefore, if we apply this concept to this problem, we infer that as the temperature of the water in the pond gets higher, the speed of the molecules inside the water increases, which means that the molecules are moving faster.

Therefore, the correct answer is

B) the molecules started moving faster.
