Electromagnetically decreases when the elements are considered in order of increasing atomic number.
In this problem they were asking regarding group 17.
Final answer: Electromagnetically
Answer:
37.5 g NaCl
Explanation:
Step 1: Given data
- Concentration of NaCl: 15.0% m/m
- Mass of the solution: 250.0 g
Step 2: Calculate how many grams of NaCl are in 250.0 g of solution
The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.
250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl
Answer:
I think that the statement is relative to speed because it is saying km per second.
Answer:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Explanation:
Chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Balanced chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
The given reaction is double displacement reaction in which anion and cation of both reactant exchanged with each other. Calcium hydroxide react with sulfuric acid and form calcium sulfate and water.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
