C + 2ZnO → CO2 + 2zn
How many grams of
carbon dioxide will be
produced if 135 grams
of ZnO is completely
reacted?
Answer:
36.5 g CO2
Explanation:
First, Write a Balanced Equation
C + 2 ZnO → CO2 + 2 Zn
Useful Information,
MW of ZnO = 81.41 g
MW of CO2 = 44.01 g
135 g ZnO x (1 mol ZnO / 81.41 g ZnO) x (1 mol CO2/2 mol ZnO) x ( 44.01 g CO2 / 1 mol CO2 ) = 36.5 g CO2
Stem cells can differentiate into how many types of body cells?
Given this balanced equation: CS2 + 3 O2 CO2 + 2 SO2
Calculate how many moles of SO2 can be produced with when given 4 moles of CS2.
58.67 g
Now calculate how many moles of SO2 can be produced with when given 4 moles of O2.
Which one is the limiting reactant (4 moles CS2 or 4 moles of O2)? How do you know?
Answer: The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
Explanation:
The ocean pressure at the depth of the Titanic wreck is 400 atm . Calculate the ocean pressure in kpa?
A)3.00 × 10^4 kPa
B)4.05 × 10^4 kPa
C)4.05 × 10^3 kPa
D)4.05 × 10^2 kPa
Answer:
4.05 × 10⁴ kPaExplanation:
To find the pressure in kPa we use the conversion
1 atm = 101.3 kPaIf 1 atm = 101.3 kPa
400 atm = 400 × 101.3 = 40520 kPa
Expressing it in standard form we have the final answer as
4.05 × 10⁴ kPaHope this helps you

If a lab requires you to use 1.25 mol oxygen gas in a chemical reaction, how many molecules of oxygen will you need?
Answer:
7.53*10²³ molecules of oxygen will you need.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.
You can then apply the following rule of three: if by definition of Avogadro's Number 1 mole of oxygen gas contains 6.023*10²³ molecules, 1.25 moles contains how many molecules?
[tex]amount of molecules=\frac{1.25 moles*6.023*10^{23}molecules }{1 mole}[/tex]
amount of molecules= 7.53*10²³
7.53*10²³ molecules of oxygen will you need.

Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma
Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.

A student adds 5400.0mL of 0.15M NaOH to 201.2mL of 4.0M NaOH. What is the final [NaOH]?
Answer:
0.287 M
Explanation:
Multiply the concentration of each solution by the volume of each (in liters) to get the moles of NaOH in that solution.
0.15 M • 5.4000 L = 0.81 mol NaOH
4.0 M • 0.2012 L = 0.80 mol NaOH
Add the mol of NaOH together to get the total --> 0.81 + 0.80 = 1.61 mol NaOH
Divide by the total volume of solution (5400.0 mL + 201.2 mL = 5,601.2 mL = 5.6012 L)
1.61 mol / 5.6012 L = 0.287 M NaOH
