Answer:

Explanation:

Answer:

true

Explanation:

Students often have no experience with the idea that some things (particles) can’t be divided. If sand is ground up into tiny pieces it is still sand. There seems no reason why the dividing can’t keep on going to smaller and smaller pieces. This is often described as a continuous view of matter.

Even when children are introduced to the idea of matter being made of particles, most consider there is still ‘stuff’ between the particles and that something like air fills the empty space. After all, when liquid is poured from a glass so that it is empty it still contains air.

These ideas are further explored in ‘Hannah’s Question,’ a classroom practice vignette.

Research: Loughran, Berry, Mulhall & Gunstone (2001), Novick & Nussbaum (1981)

Particles are often assumed to behave in the same way as the substances they make up. For example students can believe that particles themselves can swell, shrink and melt or that the particles in stone are harder than the particles in rubber. Many students consider that ice molecules melt to little droplets of water.

Scientific view

The properties of matter can best be explained using a model in which all materials are composed of tiny particles (atoms, molecules and ions).

There is empty space between particles and particles are constantly moving (their speed is changed by temperature). The particles in solids and liquids are quite close to each other, while those in gases are a very long way apart. (There is commonly an increase in volume of at least 1000 fold when substances move from solid or liquid to gas).

Changes of state involving solids, liquids and gases as well as a range of other phenomena can be explained by changes in arrangement and speed of the particles.

Answer:

decreases

Explanation:

Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell.

Hi!one molecule of pyruvate contains three carbon atoms.

Glycolysis produces two pyruvate molecule and there are three carbon atoms are present in each pyruvate molecule.

Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytoplasm of a cell and does not require oxygen. It occurs in both aerobic and anaerobic organisms.

There are two pyruvate molecules produced at the end of glycolysis for every molecule of glucose metabolized. Therefore, two of the six original carbons will have been eliminated as CO2 at the end of this step.

The main purpose of glycolysis is to provide pyruvate for the trichloroacetic acid (TCA) cycle, not to make adenosine 5′-triphosphate.

Thus, there are three carbon atoms are present in pyruvate compound.

The solubility of the gas when the pressure is decreased to 101 KPa at constant temperature is 0.853

This states that the solubility of a gas in liquids at constant temperature is proportional to its pressure. Mathematically, it can be expressed as

S₁ / P₁ = S₂ / P₂

Where

From the question given above, the following data were obtained

S₁ / P₁ = S₂ / P₂

0.98 / 116 = S₂ / 101

Cross multiply

116 × S₂ = 0.98 × 101

Divide both side by 116

S₂ = (0.98 × 101) / 116

S₂ = 0.853

Answer:

12.1; acidic

Explanation:

I'm assuming the hydrogen concentration is H+.

So, first we must find pH.

pH = -log[H+]

I simply just plugged in the concentration.

I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.

Now to find poH.

poH + pH = 14

I simply plugged in once again!

I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.

Answer: Heyo Kenji Here! Here's your answer- Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an -ene (alkene) or -yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.

Explanation: Hope this helps!

Have a nice day!

Answer:

Alkene and alkyne compounds are named by identifying the longest carbon chain that contains both carbons of the double or triple bond.

Explanation:

With the increase in temperature, the state of matter of water will changed.

If the temperature of water is increased then the state of matter will change from liquid state to gaseous state because the temperature break down the bonds that is present between two water molecules.

So we can conclude that with the increase in temperature, the state of matter of water will changed.

Molar mass of Mg(NO_3)_2

Moles of solute:-

Now

Molarity:-

Answer: 100 mL

Explanation:

The number of mole of nitrogen gas in the 16.8 L container is 0.75 mole

Data obtained from the question

Volume (V) = 16.8 L

Pressure (P) = STP = 1 atm

Temperature (T) = STP = 273 K

Gas constant (R) = 0.0821 atm.L/Kmol

Number of mole (n) =?

How to determine the number of mole

The number of mole of the nitrogen gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by RT

n = PV / RT

n = (1 × 16.8) / (0.0821 × 273)

n = 0.75 mole

Thus, the number of mole of the gas present is 0.75 mole

High specific heat capacity and long liquid range of water make it a good coolant especially in the nuclear plants

High specific heat capacity implies that it takes a very large amount of heat for the temperature of water to change by 1K. This means that water does not heat up easily and does not loose heat easily.  Ideally, this informs the long liquid range of water.

These properties together make water a good coolant especially in the nuclear plants where temperatures could get very high.

Answer:

4.7 Liters of NO2

Explanation:

mole weight of HNO3  (from periodic table) = ~~ 63 gm/mole

  12 grams of this is   12/63 = .19047 mole

From the equation, you should be able to see that 3 moles of NO2 produces 2 moles of HNO3

  so you need  3/2 * moles HNO3 = .2857 moles of NO2 needed

PV = nR T     n = moles   R = .082057 L-atm/(k-mole)    25 C = 298.15 K

1.6 (V) = .2857 (.082057)(298.15)

  solve for V = 4.37 liters of NO2

The changes occur in reaction are the bond in H₂ is broken, and new bonds are formed between hydrogen and oxygen atoms.

Hydrogen bond is a type of chemical bond which is formed between the hydrogen atom and more electronegative atom due to high dipole interaction.

Given chemical reaction is:

2H₂ + O₂ → 2H₂O

In the above reaction hydrogen nucleus not loses proton inspite of that it was broken and new bond formation takes place in water.

Despite the fact that oxygen atoms attract electrons from hydrogen atoms, oxygen atoms do not gain electrons.

In the water molecule each electron of both hydrogens is shared with an oxygen atom.

As a result, in the preceding equation, the hydrogen molecule's bond is broken, a new bond is formed, and each hydrogen atom's electron is shared with an oxygen atom.
