Answer: The crest and trough of two waves intersect.

Explanation:

The best description of the constructive interference of light is the crest and trough of two waves intersect.

When two waves travel in the same direction and are in phase with each other, their amplitude gets added, and the resultant wave is obtained. Here, the waves are said to have undergone constructive interference.

Constructive interference is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the same direction

Answer:

1. 208

2. 82

3. Pb

Explanation:

²¹²₈₄Po —> ⁴₂He + ᴬZX

1. Determination of mass number A of the new atom.

212 = 4 + A

Collect like terms

212 – 4 = A

208 = A

A = 208

Thus, the mass number is 208

2. Determination of the atomic number Z of the new atom.

84 = 2 + Z

Collect like terms

84 – 2 = Z

82 = Z

Z = 82

Thus, the atomic number is 82.

3. Determination of the symbol of the new atom.

ᴬZX => ²⁰⁸₈₂X

The atomic number of the new atom is 82. Comparing the atomic number of the new atom to those in the periodic table, the new atom is lead with symbol Pb.

Thus,

²⁰⁸₈₂X => ²⁰⁸₈₂Pb

Therefore, the symbol of the new atom is Pb.

Answer:

Precautions must be taken to remove all possibilities of fire or explosion.

Explanation:

Since Hydrogen is a very flamable or combustible gas, it is neccesary to avoid smoking, remove sourcs of sparks, flames or heat and hydrogen should be used in a well ventilated area.

Answer:

The generation and use of hydrogen is dangerous.  Mixtures of hydrogen and air can be highly explosive.  Never smoke near a place where hydrogen is generated or being used.  Remove all possible sources of flame and sparks.  Hydrogen should only be generated and used in a well ventilated out door area.   Precautions must be taken to remove all possibilities of fire or explosion.

The first few bubbles of hydrogen gas should not be collected since they contain air mixed with the gas. Air mixed with hydrogen forms an explosive mixture.

A flame should not be brought near the apparatus since hydrogen is inflammable.

9: D. A substance has changed chemically

10: A. a chemical change because the marshmallow changed in taste, color and smell

Explanation:

On the roasting of marshmallows, a chemical change takes place which changed their taste, color, and smell. Therefore, option (A) is correct.

A chemical change is a type of change in which the molecular composition is altered and a new substance is formed is known as a chemical change.

The changes are irreversible and permanent in chemical change. The mass of the substance is altered by adding or removing it during a chemical change.

During a chemical change, there is an energy difference in the breaking of old bonds and the formation of new bonds.

When marshmallows are roasted, a chemical change takes place. The heat causes a chemical reaction producing water molecules, which evaporate and leave carbon behind.

The marshmallow swells as the moisture inside expands, which causes the marshmallow to swell. when the moisture expands, it forms tiny holes in the marshmallow, which offer the moisture to escape as steam.

Then, the carbon present in sugar burns with the oxygen in the air. The blackened part of the marshmallow is the roasted carbon which changes the marshmallow's color.

What is true about the particles?

D. They stay in place and vibrate.

Answer:

45594J

Explanation:

Needed information in this question are;

Specific heat of ice = 2.06 J/g°C

Specific heat of water = 4.18 J/g°C

Specific heat of steam = 2.03 J/g°C

Heat of fusion of water ΔHf = 334 J/g

Melting point of water = 0 °C

Heat of vaporization of water ΔHv = 2257 J/g

Boiling point of water = 100 °C

- STEP 1:

Q1 = mcΔT

where

m = 15 grams

c (specific heat of ice) = 2.06 J/g°C

Tinitial = -5 °C

Tfinal = 0 °C

ΔT = (Tfinal – Tinitial)

ΔT = (0 °C - (-5 °C))

ΔT = 5 °C

Q1 = mcΔT

Q1 = (15 g) · (2.06 J/g°C) · (5 °C)

Q1 = 154.5 J

- STEP 2:

Q2 = m · ΔHf

where

m = 15 grams

ΔHf (heat of fusion) = 334 J/g

Q2 = m · ΔHf

Q2 = 15 · 334 J/g

Q2 = 5010 J

- STEP 3:

Q3 = mcΔT

where

m = 200 grams

c (specific heat of water) = 4.18 J/g°C

Tinitial = 0 °C

Tfinal = 100 °C

ΔT = (Tfinal – Tinitial)

ΔT = (100 °C – 0 °C)

ΔT = 100 °C

Q3 = mcΔT

Q3 = (15 g) · (4.18 J/g°C) · (100 °C)

Q3 = 6270 J

- STEP 4:

Q4 = m · ΔHv

where

m = 15 grams

ΔHv (heat of vaporization) = 2257 J/g

Q4 = m · ΔHf

Q4 = 15 · 2257 J/g

Q4 = 33855 J

- STEP 5:

Q5 = mcΔT

where

m = 15 grams

c (specific heat of steam) = 2.03 J/g°C

Tinitial = 100 °C

Tfinal = 110 °C

ΔT = (Tfinal – Tinitial)

ΔT = (110 °C – 100 °C)

ΔT = 10 °C

Q5 = mcΔT

Q5 = (15 g) · (2.03 J/g°C) · (10 °C)

Q5 = 304.5 J

Total heat = 304.5J + 33855 J + 6270 J + 5010 J + 154.5 J

= 45594J

Explanation:

2SO2(g) + O2(g) <=> 2SO3(g). Delta H = -198.2 kJ/mol. exothermic

Answer:

2

Explanation:

The coefficient for O is 2 and this is an example of a combustion reaction. With the help of the coefficient 2 infront of oxygen, this equation now demonstrates law of conservation of mass.

The coefficient for O₂ that demonstrates the law of conservation of mass is

2.

The law of conservation of mass states that mass can neither be created

nor destroyed but can be transformed from one form to another.

The mass of the reactant and the mass of the product should be equal.

Therefore, let's balance the equation

CH4 (g) + 0₂(g) → CO₂(g) + 2H₂O(g)

For the equation to be balanced the masses of each molecules on both

sides will be the same .

Therefore,

CH4 (g) + 20₂(g) → CO₂(g) + 2H₂O(g)

The coefficient of 2 for O₂ will balance the masses of oxygen on both

sides of the chemical equation.

Answer:

The gas has been cooled down

Explanation:

molecules move slower and slower and have less and less kinetic energy if you cool it down but it also has something to do with how big the particles are, how heavy they are, and their temperature. If the particles are heavier and bigger they will move slower.

And if their temperature is colder that will also cause them to move slower. Hope this helps!!

Answer & Explenation:

2H2 + O2 -> 2H20 is the balanced equation for the reaction of Hydrogen with Oxygen to form water so

If you have 32g of O2 this is a simple Dimensional analysis problem

32g O2 x 36.03056g H20/31.9988g O2 this way the O2 cancels out and you are left with just the H2O so your raw answer would be 36.0319112, then if your instructor requires a significant figure answer that would be to 2 significant figures the information you were given 32g O2, so as above 36g or Water are produced. Just a different way to view and solve the problem with the balanced equation so you can see the way everything relates to everything else. the molar masses of O2 and H2O are simply found my adding up 2 Oxygens 15.9994g x2 = 31.9988g and H2O = 2(1.00794) + 15.9994 = 18.01258 but you then have to multiply that by 2 because the reaction states you get 2 mols in the reaction so that is where I came up with the 36.03056g for the solution. Hope this helps. Dimensional Analysis is and can be one of the best ways to solve these problems, because not always are you going to be dealing with 1:2 ratios.

According to the forces of attraction, when you boil a pot of liquid water, the water turns to steam and rises in the air. This is an example of evaporation.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.
