The volume of the hydrogen gas would be 116.022 L
<h3>Density</h3>
The density of an object is a measure of how heavy the object is.
Mathematically, the density of an object is given by:
Density = mass/volume.
Thus, given 2 out of the 3 variables that make up the equation, the unknown variable can be calculated.
In this case, the mass and the density of hydrogen were given as 10.326 g and 0.089 g/L respectively.
Therefore, we need to find the volume by making it the subject of the formula from the equation above.
Volume = mass/density.
10.326/0.089 = 116.022 L
This means that the volume of the hydrogen gas is 116.022 L

Answer:
i would say 10, so the anser is A.
Explanation:
because there are the same number of protons and electrons, therefore for a regular O, you are supposed to have only 8 protons, but it is charged, thus, whatever the charge is will be taken into consideration into how much the proton and electron doe it have. Thus, for this case, it has 10, because the charge is negative and you have 8 electron plus 2 = 10.
Answer:
D. Because we cannot easily detect them.
Explanation:
Dark matter are called dark because using existing astronomical instruments we are blinded to them. Dark matter and dark energy are difficult to detect and properly observe. As we know that the whole universe is made up of matter, some of the matter do not interact with the electromagnetic radiations which makes undetectable.
M=(mols/L) so M=(9.0/2.5) which is 3.6M
N a polar covalent bond<span>, the electrons shared by the atoms spend a greater amount of time, on the average, closer to the Oxygen nucleus than the Hydrogen nucleus. This is because of the geometry of the molecule and the great electronegativity difference between the Hydrogen atom and the Oxygen atom.</span>
