the atoms in an oxygen molecule.
Answer:
here hope it helps
Explanation:
covalent bonds
Answer:
please check image and explanation
Explanation:
First write the balance chemical reaction
CO(g)+2H2(g)⇌CH3OH(g)
To find out the equilibrium constant first need to find the concentration of each entities at equilibrium.

We are given the amount of CaCO3 to decompose when heated. This will be our starting point.
98.60 g CaCO3 ( 1 mol CaCO3 / 100.09 grams CaCO3) (1 mol CaO / 1 mol CaCO3 ) ( 56.08 g O2 / 1 mol CaO) = 55.25 g CaO
0.9851mol. This is the rt answer just did it
Alkali metals
O Noble gases
O Transition metals
The formula for specific gravity is:
where is the density of the substance and is the density of water.
The density of water, =
Substituting the values in above formula we get,
The formula of density is:
The density of mercury is
The mass of mercury is
Substituting the values in density formula:
The amount, in milliliters, of mercury that will have a mass of 0.35 kg would be 25.74 mL.
If the specific gravity of mercury is 13.6, the density can be obtained such that:
Density of mercury = specific gravity of mercury/density of water
The density of water is 1 g/mL. Thus:
Density of mercury = 13.6/1
= 13.6 g/mL
Also; density = mass/volume
volume = mass/density
= 350/13.6
= 25.74 mL
Thus, the number of milliliters of mercury that will have a mass of 0.35 kg would be 25.74.
