Answer: B. Adding more protons to a positively charged body until the number of protons matches the number of electrons
Explanation:
took test got it right
Answer: True.
Explanation.
The group 7A is actually named group 17.
That group is the halogens: F, Cl, Br, I, At, and Ts (Ts is one of the last elements discovered).
Those elements have 7 valence electrons (notice that it is the same number as the second digit in 17).
The atoms with 7 valence electrons will "easily" gain one electron to get the configuration of the next noble gas (8 valence electrons). That is why these elements gain electrons to form ions.
When atoms gain electrons form anions (negative ions). For example: F(-), Cl(-), Br(-), I(-).
Answer:
0.2349 moles, 10.3356 g
Explanation:
The given reaction is :
The balanced reaction by equating the same number of each atom both side is :
Given that :
Amount of oxygen gas = 11.9 g
Molar mass of oxygen gas = 32 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
From the reaction,
19 moles of oxygen gas on reaction forms 12 moles of carbon dioxide
Also,
1 mole of oxygen gas on reaction forms 12/19 moles of carbon dioxide
So,
0.3719 moles of zinc on reaction forms 
mole of carbon dioxide
<u>Moles of carbon dioxide formed = 0.2349 moles</u>
Mass of carbon dioxide = moles×Molar mass
Molar mass of carbon dioxide = 44 g/mol
<u>Mass of carbon dioxide formed = 0.2349 ×44 g = 10.3356 g</u>
The volume of 0.15M NaOH that could be produced with only 5 grams of NaOH and water is 0.83L.
<h3>How to calculate volume?</h3>
The volume of a substance can be calculated using the following expression:
Molarity = number of moles ÷ volume
The number of moles of NaOH can be calculated by dividing the mass of NaOH by its molar mass.
Molar mass of NaOH = 40g/mol
n = 5/40
n = 0.125moles
Volume of NaOH = 0.125mol ÷ 0.15M
Volume = 0.83L
Therefore, the volume of 0.15M NaOH that could be produced with only 5 grams of NaOH and water is 0.83L.
