2. Two glasses full of water are left out on a table over
night. Both glasses have a diameter of 10
centimeters, but one is twice as tall as the other.
Which glass do you expect to lose more liquid to
evaporation in a short amount of time?
A.The taller glass
B.The shorter glass
C.They both lose the same amount
D.No evaporation takes place

Answers

Answer 1

Answer: C

Explanation: The evaporation rate depends on the exposed surface of liquid as long as both glasses stay at the same temperature. Since both glasses have the same surface area, they should both evaporate at the same rate.

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

Oxidation state of Ruthenium?

Answers

Answer:

0 to +8, and −2

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

Melting point: 2,250° C (4,082° F)

and the most stable oxidation state of ruthenium is +8

How many mL of 3.0 M HCl are needed to make 300.0 mL of 0.10 M HCl?

Answers

Answer:

V₁  = 10 mL

Explanation:

M₁V₁  =  M₂V₂

M₁ = Initial molarity

V₁  =  Initial volume of HCl

M₂ =Final molarity

V₂ = Final volume

Now we will put the values.

3.0 M ×V₁  =  0.10 M×300.0 mL

3.0 M ×V₁  = 30 M.mL

V₁  = 30 M.mL /3.0 M

V₁  = 10 mL

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.
