Which of the following is not the same as 0.032 liters?

1 answer:

3 0

This question needs the answer choices.

I found these choices for you:
0.00032hL
320cL
32mL

Then you need to make the conversion of 0.032 liters to hectoliters, centiliters and milimilters to check which is not equivalent.

1) 0.032 liters to hectoliters:

 0.032 liter * 1 hectoliter / 100 liter = 0.00032 hecoliter

2) 0.032 liter to centiliters:

 0.032 liter * 100 centiliters / 1 liter = 3.2 centiliter

3) 0.032 liter to mililiter:

 0.032 liter * 1000 mililiter / liter = 32 mililiter

Then, the answer is 320 cL: 320 cL is not the same as 0.032 liters

Assuming that the solubility of radon in water with 1 atm pressure of the gas over the water at 30 ∘C is 7.27×10−3M, what is the

Daniel [21]

Answer:

K = 137.55 atm/M.

Explanation:

The relationship between gas pressure and the concentration of dissolved gas is given by Henry’s law:

P = (K)(C)

where P is the partial pressure of the gaseous solute above the solution (P = 1.0 atm).

k is a constant (Henry’s constant).

C is the concentration of the dissolved gas (C = 7.27 x 10⁻³ M).

∴ K = P/C = (1.0 atm)/(7.27 x 10⁻³ M) = 137.55 atm/M.

A reaction mixture initially contains 0.140 MCO and 0.140 MH2O. What will be the equilibrium concentration of CO?

Allushta [10]

Answer:

0.013 M

Explanation:

From the question, we can make the following deductions; we are given mixture that contains two compounds, that is A and B, 0.140 M CO and 0.140 M H2O respectively. Then, we are asked to find the equilibrium concentration of Carbonmonoxide,CO.

So, the equation for the reaction is given below;

CO + H2O <-----------------> CO2 + H2.

Initially: we have 0.14M of CO, 0.14M of H2O and zero (0) concentration of CO2 and H2.

At time,t = CO =0.14 - x , H2O = 0.14 - x, CO2 and H2 = x.

The above reaction consist of the forward reaction and the backward reaction.

Therefore, the equilibrium Concentration of CO;

(Since we are giving that Kc = 102). Then, Kc= [CO2][H2] ÷ [CO][H2O]. Where Kc is the equilibrium constant.

Therefore, 102 = [x^2] / [0.14 - x]^2.

==> 10.1= x/0.14 - x.

====> 0.141 - 10.1 x = x.

x + 10.1 x = 0.141.

===> 11.1 x = 0.141.

===> x = 0.141 ÷ 11.1.

===> x = 0.127 M .

Then, at time,t CO = 0.14 - x.

= 0.14 - 0.127 = 0.013 M

Finger [1]

Answer:

Check explanation section.

Explanation:

Yes, that is true. Sodium with chemical symbol Na belongs to the group 1 on the periodic table. Group 1 elements are known as Alkali metals. Other elements in the group are Caesium, lithium, Rubidium, francium and potassium.

Neon belongs to the noble gas of group 8/0.

Sodium is very reactive and and good conductor of electricity. Sodium reacts with water for the production of hydrogen (NB: this reaction is vigorous).

2Na(s) + 2H2O ------------> 2NaOH + H2(g).

They can react with nonmetals such as the halogens. For instance;

Na + Cl2 -------------------------------> 2NaCl.

Sodium is ductile and have low melting point( but high compared to neon).

Neon is not active chemically and it has no odour and no color

What is the individual ions for ZnCO3

mamaluj [8]

ZnCO3 is an inorganic compound and it contains two parts; one is cation(positive part of compound) whereas other is anion(negative part of compound). Here, $Zn ^{+2}$ is cation and $CO3 ^{-2}$ is anion. Hope this helps.
