Battery,and i think the light bulb because it depends how much energy the light bulb needs
defined, a solid will always have a definite shape and volume because it doesn´t depend on its container shape
Answer:
helium
Explanation:
By losing an electron, they look like the noble gas that immediately precedes them on the periodic table.
Answer:
15.17 g
Explanation:
To answer this, we need to find the molar mass of nickel in nickel (II) fluoride. The formula for nickel (II) fluoride is NiF2. This gives us the molar mass of 96.69 g. The mass percentage of nickel is 60.70% approximately (as we divide the molar mass of nickel by that of nickel (II) fluoride), and 60% of 25g gives us 15.17 g
Answer:

Explanation:
Hello,
In this case, the reaction between sulfuric acid and hydroxide is:

We can notice a 1:2 molar ratio between the acid and the base respectively, therefore, at the equivalence point we have:

And in terms of volumes and concentrations:

So we compute the molarity of sulfuric acid as shown below:

Best regards.
