Identify the parts of the atom that are labeled in the diagram
baherus [9]

Answer:

A- Nucleus

B-Energy levels

Explanation:

  • An atom refers to the smallest particle of an element that can take part in a chemical reaction.
  • An atom is made up of two major parts namely; the nucleus and the energy shell or energy levels.
  • The nucleus of an atom contains the sub atomic particles, protons and neutrons while the energy shells contain the sub atomic particle electrons.
  • It is important to note that the protons in the nucleus are positively charged which makes the nucleus to be positively charged.
  • On the other hand, energy shells are negatively charged because of the negative charge of the electrons.

What is the percent by mass of magnesium sulfate in MgSO4 · 7H2O?
AfilCa [17]
ANSWER - 48.83%

Mg - 24.31
S - 32.07
O - 16x4 - 64
ADD ALL TOGETHER = 120.38

H - 1.01x2 - 2.02
O - 16
TOTAL = 18.02x7 = 126.14

ADD 120.38 to 126.14 = 246.52
last part divide MgSO4 by total compound mass 
120.38/246.52 then multiply by 100 = 48.831

A student takes a measured volume of 3.00 M HCl to prepare a 50.0 mL sample of 1.80 M HCl. What volume of 3.00 M HCl did the stu
Pani-rosa [81]

83.3 mL

Explanation:

M_{i} = 3M

V_{i} = 50mL

M_{f} = 1.80M

Unknown:

V_{f} = ?

Solution:

To solve this problem we must understand that the initial and final number of moles remains the same.

  Number of moles = molarity x volume

Molarity x volume of initial solution = Molarity x volume of final solution

 Therefore:

   M_{i}  x  V_{i}     = M_{f} x   V_{f}

M is the molarity

V is the volume

i = initial state

f = final state

    input the parameters;

  3 x 50 = 1.8 x V_{f}

      V_{f} = 83.3 mL
