Answer 2

Answer:

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. first question Natural non-living things: They are found in nature and are not made by man. Examples: Sun, moon, stars, sky, clouds, rocks, mountains and many more. Man-made non-living things: They are made by man. Examples: Toys, chairs, tables, beds, houses, buildings, trains and many more. second question Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form". third question. Sedimentary. fourth question and sorry I can't answer the last :(

A 1lbs
Sorry I meant math.
B 2lbs

C 6lbs
D 7lbs

Answers

Answer:

2pounds

Explanation:

Given parameters:

Weight of Pedro's book  = [tex]\frac{19}{4}[/tex] pounds

Weight of Blanca's book  = [tex]\frac{17}{7}[/tex] pounds

Unknown:

How much more does Pedro's book weigh more than Bianca's book ?

Solution:

To Solve this problem, let us convert the fractions to decimal;

   Weight of Pedro's book  = 4.75 pounds

   Weight of Bianca's book  = 2.43 pounds

Differences  = 4.75pounds - 2.43 pounds

                     = 2.32 pounds

Estimating gives 2pounds

How many atoms are in 1.65 mol of potassium

Answers

Answer:

9.93 × 10²³ atoms

Explanation:

The number of atoms of potassium can be found by using the formula

N = n × L

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 1.65 × 6.02 × 10²³

We have the final answer as

9.93 × 10²³ atoms

Rosa lives in New York City, which has an average altitude of 33 feet. When she is at home, it takes her 10
minutes to cook noodles in boiling water. She decides to go on a camping trip to Mount McKinley. Her
campsite is located 11,000 feet above sea level. Write the answer to each.
A) Where will the atmospheric pressure be higher: at her home or her campsite?

B) Where will the boiling point be higher?

C) Will the noodles cook faster, slower, or at the same rate at her campsite than home?

Answers

Answer:

Home

Home

Slower

Explanation:

A liquid starts changing its phase to gas when the two pressures become the same i.e., vapor and atmospheric.

At a higher altitude the atmospheric pressure lowers so little amount of heat is required for the vapor pressure of water to equalize with the atmospheric pressure at a higher altitude.

The pressure at the Rosa's home will be higher and lower in the campsite.

The boiling point will be higher at her home.

As the boiling point is lower in the campsite the water used in cooking noodles will evaporate faster this may lead to the noodles being under cooked. The water may evaporate before the noodles have cooked. So, the noodles will cook at a slower rate at the campsite and faster in her home.

A. The atmospheric pressure at Rosa's home is higher than her campsite.

B. The boiling point of water at Rosa's home is higher.

C. The noodles will be cooked faster at Rosa's home compared to at the campsite

A. The pressure has been the force that has been exerted by the molecules against each other, The higher altitude has lesser air molecules, which resulted in the lower pressure.

Since the pressure at 33 feet has been higher as than the pressure at 11,000 feet altitude, the atmospheric pressure at Rosa's home is higher than her campsite.

B. The boiling point has been the temperature at which liquids have been converted to gases. With the decrease in atmospheric pressure, there has been a lowering in the boiling point as well.

The atmospheric pressure at Rosa's home is higher compared to her campsite. Thus, the boiling point of water at Rosa's home is higher.

C. The lower atmospheric pressure at the campsite has been responsible for the lower boiling point of the temperature, This implies that water has converted to steam at lower temperatures. The lower temperature of water requires more time for the noodles to be cooked.

Thus, the noodles will be cooked faster at Rosa's home compared to at the campsite.

Which of the following characterizes a reaction at equilibrium?​

Answers

I’m pretty sure the correct answer is D.

A reaction comprises a reactant and a product. It is said to be in equilibrium when the rates for the forward and reverse reactions are equal. Thus, option D is correct.

What is an equilibrium reaction?

An equilibrium reaction is a thermodynamic condition where the reactants and the products are at a stable position even before and after the reaction. They remain fixed and do not vary with the addition of any catalyst.

In the equilibrium position, the reaction rate of the forward (product formation) and reverse (reactant formation) remains the same and is seen in the reversible reactions only.

The amount of the products and the reactant remains constant till the temperature is constant but may vary if the tempearture is varied.

Therefore, the rate of reverse and forward are equal in the equilibrium reaction.

Hydrogen bond is not formed by 1) oxygen 2) nitrogen 3) chlorine
PLEASE HELP!!!
i mean which cant form hydrogen bond

Answers

Answer:

Chlorine

Explanation:

Even though chlorine is highly electronegative, the best answer is no, and in this class we will consider chlorine not to form hydrogen bonds (even though it has the same electronegativity as oxygen). This is because chlorine is large and its lone electron is in a diffuse orbital, covering a large area, and thus do not have the high charge density to act as a strong hydrogen bond acceptor. But it does form weak hydrogen bonds in solid crystalline hydrogen chloride at very low temperatures.

How many moles of Nitrogen gas are in 135L of Nitrogen gas at STP?

Answers

Explanation:

P×V=n×R×T

L×atm / mol×K

n= PV /RT

Description:

So as we know that our Known variables: are P, V, R, T and our unknown variables are n. N= PV / RV. = 6.02 moles.

Answer: 6.02  moles

Hope this helps.

The moles of nitrogen gas present in 135 L at STP have been 6.02 moles.

The nitrogen gas has been assumed to be the ideal gas. For an ideal gas, at STP or standard pressure and temperature, the volume of 1mole of gas has been 22.4 L.

The STP conditions have been 273.15 K temperature, and 1 atm pressure.

Since, moles in 22.4 L gas been 1 mole. The moles in 135 L gas has been:

22.4 L = 1 mole

135 L = [tex]\rm \dfrac{1}{22.4}\;\times\;135\;moles[/tex]

135 L gas = 6.02 moles.

The moles of nitrogen gas present in 135 L at STP have been 6.02 moles.

An atom has a mass number of 65. Its number of

many protons, neutrons, and electrons does this atom
have? What is the identity of this atom? *
(justify your answer step by step!)

Answers

Answer:

25 protons, 25 electrons, 30 neutrons. ......... manganese is the identity

Explanation;

x = atomic number -# of protons

The number of neutrons = x + 5

The mass number (sum of protons + neutrons) = 55.

x + (x + 5) = 55

2x + 5 = 55

2x = 50  

x = 25; atomic number 25 = manganese (Mn)

so ;

25 = Protons

30=Neutrons  

25=Electrons
