Guys im going to be going over these with my teacher tomorrow so please help me if u have a little bit of humanity inside you ASAP

Answer:

Yes.

Explanation:

Wasting household water does not ultimately remove that water from the global water cycle, but it does remove it from the portion of the water cycle that is readily accessible and usable by humans. Also, "wasting" water wastes the energy and resources that were used to process and deliver the water.

Answer:

I feel like there should be more parts to this question but I think it depends on how you got your water. If you waste water after you got it from a local stream yourself, you wasted your body energy but no real electricity of any kind. If the water is processed and filtered and you end up wasting it, I guess it counts as energy being wasted too? Because the sole purpose was to bring you clean water but you didn't utilize it

Promoters are substances that increase the catalytic activity, even though they are not catalysts by themselves.

Inhibitors are sometimes referred to as "negative catalysts" since they decrease the reaction rate.

Answer:

13.65 moles

Explanation:

The equation of the reaction is;

3Ca(NO3)2 + Cr2(SO4)3 = 3Ca(SO4) + 2 Cr(NO3)3

4.55 moles of chromium (iii) sulfate reacts with calcium nitrate

The mole ratio of Chromium (iii) sulfate to calcium nitrate is 1: 3

Therefore; the moles of calcium nitrate will be given by

 = (4.55/ 1)×3

= 13.65 moles

Hence; 13.65 moles of calcium nitrate would react with 4.55 moles of Chromium (iii) sulfate.

Answer:

One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number. Mole is inversely proportional to molar mass.

Mathematically,

mole =given mass ÷ molar mass

Number of atoms = moles ×6.022×10²³ atoms

Substituting the values in above formula we get

Number of atoms = 1 ×6.022×10²³ atoms

Number of atoms 1 mole of calcium = 6.022×10²³ atoms

Therefore, number of atoms in 1.00 moles of Calcium (Ca) are 6.022×10²³ atoms.

Explanation:

the particles in the air are packed apart whereas the particles in steel are closely packed and sound travel faster in solids than in gasses..

Answer:

False

Explanation:

The speed of sound is quickest in mediums that have their molecules close apart.  The speed of sounds is quickest in solids, followed by liquids, and slowest in gasses.  The close the molecules are together, the quicker sound travels.  The sound would travel faster in the steel than in the air.

This is due to the fact that sound waves are compression waves.  This means that they rely on the way molecules collide with one another and act sort of like a spring.  

Fun fact: In the old days, people used to put their ears to the train tracks to see if a train is coming.  Sound moves so fast in metal that they can sense the vibrations miles before the train arrived.

The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.

When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases

Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

Answer:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

Answer:

5.6 L

Explanation:

We can apply Charles' Law here since our pressure is constant (will not change inside the refrigerator) and we are relating change in volume with change in temperature:

V₁ / T₁ = V₂ / T₂ where V₁ and T₁ are initial volume and temperature, and V₂ and T₂ are final volume and temperature. Let's plug in what we know and solve for the unknown:

28.0 L / 25 °C = V₂ / 5 °C => V₂ = 5.6 L

5.6 L is our new volume (at 5 °C).

Answer:

Explanation:

Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.
