Answers

Answer 1

When a wave moves through the air and comes into contact with an object, it hits its flat surface from a new angle, causing the wave to refract.

When a wave passes through one material and moves through another, how does its direction change?

When waves cross the boundary between two different materials, their speed changes. For example, light waves refract when they pass through glass to air. Refraction is the effect that causes them to change direction as a result. When water waves move from deep water to shallow water (or the other way around), they refract light.

When a wave traveling through the air comes into contact with an object and bounces off its flat surface, what happens?

When waves bounce back from a surface they can't pass through, this is called reflection. When waves enter a new medium at an angle and begin traveling at a different speed, refraction occurs. Diffraction happens when waves spread out as they travel around impediments or through openings in obstructions.

What is diffusion?

Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.

There are 2 main types of diffusion:

1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.

2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.

There are 2 types of facilitated diffusion one is osmosis and dialysis.

1.8 mol HCl and 3.3 mol NaOH react accord- ing to the equation HCl + NaOH −→ NaCl + H2O . Calculate the amount in moles of NaCl formed. Answer in units of mol.

Answers

Answer:

1.8 moles of NaCl must be produced.

Explanation:

Based on the reaction:

HCl + NaOH → NaCl + H2O

1 mol of HCl reacts with 1 mol of NaOH to produce 1mol of NaCl

To solve this question we must find, as first, the limiting reactant:

1.8 moles of HCl will need 1.8 moles of NaOH for a complete reaction (Ratio of reaction 1:1). As there are 3.3 moles of NaOH,

HCl is limiting reactant

When the 1.8 moles of HCl react completely,

1.8 moles of NaCl must be produced because 1 mole of HCl produce 1 mole of NaCl

Explanation:

Answer:

In addition to carbonyl and organometallic compounds in the low oxidation states −2, 0, and +1, ruthenium forms compounds in every oxidation state from +2 to +8. Very volatile ruthenium tetroxide, RuO4, used in separating ruthenium from other heavy metals, contains the element in the +8 oxidation state.

Valence: 1, 2, 3, 4, 5, 6, 7, 8

B. 2C2H6 + 502 + 4002 + 6H20
O C. 2C2H6 + 702 4CO2 + 6H20
O D. 2C2H6 + 1002 > 4CO2 + 6H20

Answers

Answer:

C

Explanation:

Assuming you had a few typos in the equations, I would say C

I am going to assume the reaction

_C2H6 + _O2 → _CO2 + _H2O

Right now, there is enough hydrogen to make 3 water molecules, but since oxygen comes in groups of 2, it wouldn't work.

Therefore, we need 2 ethane molecules.

2C2H6 + _O2 → _CO2 + _H2O

Then balance the right side with the carbons and hydrogens

2C2H6 + _O2 → 4CO2 + 6H2O

So we need 4 O2's in carbon dioxide and 3 O2's in water (Since water uses 1 oxygen molecule per 2 hydrogens). Hence we will need 7 oxygens

2C2H6 + 7O2 → 4CO2 + 6H2O

And assuming errors in the typing, C should be the answer (if this matches)

What does q = 0.75 g x 0.897 J/g•°C x 22°C equal?

Answers

Answer:

14.8005 Joules

Explanation:

This question is describing the calculation for the amount of heat (Q) a substance absorbs or releases. The amount of heat, Q, is calculated using the formula:

Q = m × c × ∆T

Where;

Q = amount of heat (Joules)

m = mass of substance (g)

c = specific heat of substance (J/g°C)

∆T = change in temperature of substance i.e. final temperature - initial temperature (°C).

According to this question, the following expression is given:

q = 0.75 g x 0.897 J/g•°C x 22°C

To calculate this further, this will equal to: 14.8005

This means that the amount of heat, q, absorbed or released by that substance is equal to 14.8005 Joules.

Answers

Answer:

[Cl-18]⁻ & [Cl-20]⁻

Explanation:

By definition isotopes are elements with the same number of protons by different number of neutrons. Elements X-18 & X-20 have 17 protons and represent Chlorine isotopes Cl-18 & Cl-20 each with 17 protons and 18 electrons to give the isotopes a -1 oxidation state. Both isotope of chlorine have 7 electron in its valence shell and 10 electrons in its core structure.  Gaining 1 electron fills the valence octet and establishes a -1 oxidation state.
