Answer:
4.444... m/s
Explanation:
Because it increases by 40 m/s in 9 seconds so 40/9= 4.444... m/s
Answer is C
A synthesis reaction looks like this:
A+ B → AB
Answer:
Mass of gold bar is 15.8 kg
Explanation:
The gold metal bar displaces volume of water equal to volume of metal bar.
So, volume of gold metal bar = 0.82 L
We know that density is the ratio of mass to volume.
So mass of gold bar = (density of gold)
(volume of gold bar) = (
)g =15826 g
Now, 1 g = 0.001 kg
So mass of gold bar = (
) kg = 15.8 kg
Ozone depleting chemicals are most likely belong to <u>halogen </u>group on the periodic table.
<h3>Ozone depleting chemicals are most likely to belong to which group on the periodic table?</h3>
Ozone depleting chemicals are the halogen group on the periodic table. Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromo-fluorocarbons and methyl chloroform. Fluorine, chlorine, bromine, iodine, astatine and tennessine are the elements of halogen group elements. These elements greatly affected the ozone layer.
So we can conclude that Ozone depleting chemicals are most likely belong to halogen group on the periodic table.
