Answer:
it went under the process known as crystalization
Explanation:
am a chemist
Answer:
0.60 M
Explanation:
Given data:
Mass of MgS = 32.9 g
Volume of solution = 971 mL (0.971 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of MgS:
Number of moles = mass/molar mass
Number of moles = 32.9 g/ 56.38 g/mol
Number of moles = 0.58 mol
Molarity of solution:
M = 0.58 mol/ 0.971L
M = 0.60 M
Answer:
The number of energy levels increases as you move down a group as the number of electrons increases.
Explanation:
Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. 2) As you move across a period, atomic radius decreases.
Answer: It includes both a physical and chemical change
Explanation: Because the gas is turning into fire which is physical and the gas is giving out heat which is chemical
Answer:
Jodi is violating two rules; She is not wearing any safety equipment and managed to catch fire to herself. She is also not wearing gloves or safety goggles like the other two. Kimberly is leaving fire unattended, and can cause many accidents and if chemicals come in contact in the wrong way, it could be catastrophic.
