Answer:

C  Which model is composed of electrically charged particles?

Explanation:

The best question to resolve and determine the model which is plasma is to find one that is composed of electrically charged particles.

Plasma is one of the states of matter which is characterized by ions and other charged particles.

Matter is anything that has weight and occupies space.

There are four known states of matter which are:

Plasma is the only state of matter made up of charged particles.

Explanation:

One

Pressure will favor the side with the least number of mols if it the larger number of moles counts only the gases. (Le Chetalier's Principle). In this case both CaCO3 and CaO are not soluble in water. The only gas is CO2. Since it represents the most number of mols the reactant is favored.

More or Less are very troublesome words in beginning science. Make sure you understand their meaning for this question. The more pressure applied, the more the reactants will be favored and the equation shifts left.

Two

Fe and Fe3O4 are both solids. It depends on the form that water takes. Looking it up, it is shown to be in a gas form. That means if you increase the pressure, nothing will happen. That is not your question, but you should note it.

The answer to your question is you increase the concentration of Fe or H2O, the equilibrium will shift right.

If you add more Fe3O4 or hydrogen it will shift left.

Chemists say that if you alter the equilibrium the equation will shift in the opposite direction to compensate for the action you have taken.

Answer:

the elk population will increase

Explanation:

because the gray wolves eat the Elks so introducing them back into the food chain will mean that more Elks are eaten!

Answer:

2HgO    →     2Hg      +  O₂

The reaction is a decomposition reaction because from one reactant two products were obtained

Explanation:

The problem here involves balancing the chemical reaction given and also classifying the reaction.

 The unbalanced expression is given as:

              HgO    →     Hg      +  O₂

Assign the alphabets a,b and c as coefficients that will balance the equation

           aHgO    →     bHg      +  cO₂

Conserving Hg: a  = b

                   O:    a  = 2c

So, let c  = 1, a  = 2 b  = 2

Therefore;

       2HgO    →     2Hg      +  O₂

The reaction is a decomposition reaction because from one reactant two products were obtained

Answer:

volume=100

density=100

Explanation:

to get volume you multiply length and width to get area then multiply height=100

to get density you divide mass by volume

Answer:

1. 7 meters

2. gullet

4. Not sure about this

6. strong

7. digestive

8. starch

12. Not sure about this either

14. Water

15. Jejunum

19. teeth

Hope this helps!

A) high melting point

C) soluble in water

D) soluble in alcohol

E) does not conduct electricity in water

these options are a bit vague as some covalent substances dissolve in water / alcohol while some don't

Salts that are from strong bases and strong acids do not hydrolyze. Salts that are from strong bases and weak acids do hydrolyze, which gives it a pH greater than 7.  Salts of weak bases and strong acids do hydrolyze, which gives it a pH less than 7.

Explanation:

By Avagadro's Law,

V¹n¹ = V²n², where P and T are constant.

Therefore (4.00L)(0.200mol) = (3.25L)n²,

n² = 0.246mol. (3s.f.)

P.S. n² does not mean the square of n in this case, it is just a subscript.

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Combined Boyle's and Charles' gas law is used here. Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.

Ideal gas equation is the mathematical expression that relates pressure volume and temperature.

Mathematically the relation between Pressure, volume and temperature can be given as

PV=nRT

where,

P = pressure of ideal gas

V= volume of ideal gas

n =number of moles of ideal gas

T =temperature of ideal gas

R = Gas constant = 0.0821 L.atm/K.mol

By Avagadro's Law,

V₁n₁= V₂n₂, where P and T are constant.

V₁×n₁= V₂×n₂,

(4.00L)(0.200mol) = (3.25L)n²

n₂ = 0.246mol.

Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.

C. Yes, if each sample contains 6.02 x 10²³ atoms.

Explanation:

It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.

6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.

A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.

Answer:

67.58%  

Explanation:

First we convert the masses of the reactants into moles, using their respective molar masses:

By looking at the reaction equation, we know that 1.32 moles of Cl₂ would react completely with (2 * 1.32) 2.64 moles of Na. There are not as many Na moles, so Na is the limiting reactant.

Now we calculate how many NaCl moles would have been produced if all the limiting reactant was consumed:

We convert those moles to grams:

Finally we calculate the percent yield:

Efforts to control kudzu infestations have included the following methods: cutting, grazing, digging, disking, prescribed burning and application of herbicides. Roots of mature plants grow too deeply to be affected by freezing. Burning will kill only the very young plants.

Ideally, simply pulling out the heavy vines would prevent the kudzu from returning. However, you still need to kill each of the rooted stems at their crowns. Mowing or cutting back the vegetation to the ground provides the first step in removal. Then it’s time to bring out the big guns in the form of chemical herbicides.
