See if the carbon atoms are SP2 or Sp they the coplanirty is more and if its Sp3 hybridization it cant be in coplanar as Sp3 is having Td shape where as sp2 and sp are not :)

What is the mass of a 1.71-l sample of a liquid that has a density of 0.921g/ml?
Temka [501]
Hey there!:

Volume in mL :

1.71 L * 1000 => 1710 mL

Density = 0.921 g/mL

Therefore:


Mass = Density * Volume

Mass = 0.921 * 1710

Mass = 1574.91 g

Please help me with this question
Inessa05 [86]

From the calculation, the concentration in parts per billion is 6 ppb.

<h3>What is ppb?</h3>

The term ppb refers to the concentration of a substance in parts per billion. We obtain the ppb using the formula;

Mass of solute/ Mass of solution * 10^9

Now, 1L = 1000cm^3 = 1000 g

The concertation in ppb = 6 * 10^-6 g/1000 g * 10^9

= 6 ppb

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 6A element that can reasonably be expected to
NARA [144]

Answer:

Any binary molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.

Explanation:

Going down in a group increases the atomic radius and a greater atomic radius implyes greater ionic radius.  

When ionization takes place in these compounds they yelds protons (hidrogen ion) and an lewis base (anion). The greater the ionic radius the greater its stability, thus the periodic tendency is increaing the acidity of binary hidrogen compounds when going down a group. On the other hand going up a group decreases acidity, so any molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.
