Answer:
Explanation:
We can use the specific heat formula, which is:
Where <em>q</em> is the energy, <em>m</em> is the mass, <em>c</em> is the specific heat capacity, and ΔT is the change in temperature.
We know the mass is 250 grams. The specific heat capacity of water is 4.18 joules per gram degree Celsius. Let's find the change in temperature.
- ΔT = final temperature - initial temperature
Now we know all the values:
Substitute the known values into the formula.
Multiply the first 2 numbers together. The grams will cancel out.
Multiply again. This time the degrees Celsius will cancel out.
The energy needed is <u>80, 465 Joules.</u>
Write the formula of the compound.
Write the numbers of each atom in the formula. Insert the relative atomic mass for each type of atom. Calculate the total mass for each element.
Add up the total mass for the compound.
Answer:it loses one electron
Explanation:
When it loses one electron it has a noble gas configuration
Explanation:
This situation is analogous to a double replacement reaction. A double-replacement reaction occurs when parts of two ionic composites are exchanged, making two new composites. One characteristic of this kind of reaction is that there are two compounds as reactants and two different compounds as products. So, in this case we can relate with it because there are two new couples with the same members that formed the previous couples.
