B.) The sea floor is spreading where the Pacific and North American plates meet. (Converge)

C.) There is a transform boundary, commonly causing strike-slip faults, between the Pacific and the North American plates.

D.) There is a convergent plate boundary between the oceanic and continental plates.

Answer: a chemical reaction occurred because a new substance was formed with new properties!

Explanation: when u mix glue water and borax it forms into a new substance which is a chemical reaction

The students concluded after mixing the water and glue that;

A chemical change took place because a new substance was formed.

We are told that the students mixed 20 mL of white glue and 20 mL of water in a cup. These two reactants are different and we are told that 15 mL of borax solution was stirred into the mixture.

Now, the three reactants are different and they combined to form a substance that they could roll around their hands.

For them to be able to roll the product around their hands means that a new substance was formed.

In conclusion, we can say a chemical change took place as 3 different substances combined to form a new product which is not reversible like physical change.

Answer:

increases

Explanation:

it turns out that an object increases as the square of it's speed.

Answer:

Explanation:

In all physical processes taking place in closed systems, the amount of change in kinetic energy is equal to the amount of change in potential energy. If the kinetic energy increases, the potential energy decreases, and vice-versa. this equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. so therfore stays the same as the object so it would speed up as well.

Answer:

1.13 x 10²⁴formula units

Explanation:

Given parameters:

Number of moles of NH₄Cl = 1.87mol

Unknown:

Number of formula units = ?

Solution:

From mole concept;

     1 mole of a substance contains 6.02 x 10²³ formula units

Now;

    1.87 moles of  NH₄Cl   1.87 x 6.02 x 10²³ = 1.13 x 10²⁴formula units

Um did you post something I don't see nothing

Explanation:

Mass of NaCl : 5.85 g

Given

5.3 g Sodium carbonate (Na₂CO₃)

Required

Mass of NaCl

Solution

Reaction

Na₂CO₃ + 2HCl ⇒ 2NaCl + H₂O + CO₂

mol of Na₂CO₃ (MW=106 g/mol) :

= mass : MW

= 5.3 g : 106 g/mol

= 0.05

From the equation, mol ratio Na₂CO₃ : NaCl = 1 : 2, so mol NaCl :

= 2/1 x mol Na₂CO₃

= 2/1 x 0.05

= 0.1

Mass of NaCl (MW=58.5 g/mol) :

= mol x MW

= 0.1 x 58.5

= 5.85 g

I'd imagine it would look like a snowflake pretty much see through and microscopic

Answer:

Solubility may be stated in various units of concentration such as molarity, molality, mole fraction, mole ratio, mass (solute) per volume (solvent) and other units. The extent of solubility ranges widely, from infinitely soluble (without limit) ( miscible) such as ethanol in water, to poorly soluble, such as silver chloride in water.

Explanation:

Answer:

Because half filled sub levels are more stable than partially filled sub levels

Explanation:

The reason for the exceptional configuration found in some atomic orbitals is due to the special stability of half-filled sub-levels over partially filled ones.

One of the characteristic thing about filling some atomic orbitals we have to bear in mind that there is a stability conferred on an atom by being partially filled.

The energy needed to remove an electron from a half-filled configuration or inert gas configuration is very great.

This is why when there is a choice to have half-filled orbitals, it is desirous to go for this configuration.

Answer:

If sand is much denser than water, then the water will warm up faster than the sand. So yes, the kind of material—sand or water—affects the temperature change.

Explanation:

I put this as my answer :)

Good luck!! <3

Yes, the kind of material, water or sand will affect the temperature change in the experiment.

Heat produces temperature change in a body. This is one of the effects of heat. However, the extent of temperature change due to heat depends on the nature of the material. A material that has a high specific heat capacity does not undergo a large change in temperature when heat is added.

Yes, the kind of material, water or sand will affect the temperature change in the experiment. The temperature change of sand will be much higher than the temperature change in water when the same quantity of heat is added because water has a higher specific heat capacity than sand.

Answer:

The number of liters) the boy exhales is 0.499744 liters

Explanation:

The given parameters of how the boy breathes;

The number of moles of gas the boy exhales, n = 0.02231 moles

The condition in which the boy exhales the gas = STP = Standard Temperature and Pressure

The molar volume of a gas at STP, [tex]V_m[/tex] = 22.4 L per mole

Therefore, the volume of gas the boy exhales, 'V', is give as follows;

V = n × [tex]V_m[/tex]

By substituting the known values, we have;

V = 0.02231 moles × 22.4 L/mole = 0.499744 L

The volume of gas (the number of liters) the boy exhales, V = 0.499744 L.

Explanation:

First of all, the student has not represented the formula of the nitrite ion correctly. The formula of the nitrite ion is represented as NO2^- whereas the student wrote N,O2.

Then, the charge on magnesium ion has been correctly designated as +2 while the charge on the nitrite ion is correctly designated as -1. Now, the ions can exchange valencies (without signs and we now write them as subscripts) to yield Mg(NO2)2.
