Answer:
Magnesium, Carbon and Oxygen.
Explanation:
Answer:Magnesium carbonate is a magnesium salt with formula CMgO3. Its hydrated forms, particularly the di-, tri-, and tetrahydrates occur as minerals. It has a role as an antacid and a fertilizer. It is a magnesium salt, a carbonate salt and a one-carbon compound.
Explanation:
A prostate might be prescribed a total dose ionizing radiation of 72 Gy. In traditional units of rad, how many rad have been prescribed?
Answer:
7200RAD
Explanation:
Note
100RAD=1GY
Hence 72GY=7200RAD
When discussing the Arrhenius equation and chemical / enzyme kinetics, which of the following statements is incorrect ? A. A catalyst lowers the activation energy of a reaction B. A high activation energy signifies that the rate constant depends strongly on temperature C. A negative activation energy indicates that the rate increases as the temperature is raised D. The activation energy, the parameter Ea in the Arrhenius equation, is the minimum energy that a molecular encounter needs in order to result in a reaction E. If a reaction has zero activation energy, its rate is independent of temperature

How does the position of the sun, Earth, and moon affect the moon
phases, eclipses, and tides?
Answer:
It is NOT ONLY gravitational attraction. The earth casts a shadow on the moon causing the moon phases. And likewise the moon casts a shadow on the earth during a solar eclipse. A shadow meaning the object casting the shadow is between the sun and the other object. as for the tides that IS gravitational attraction. The moon pulls on the ocean to create tides
Explanation:
What is the limiting reactant when 3 grams of propane is mixed with 10 grams of Oxygen?
C3H8 + O2 —> H2O + CO2
Answer:
The answer to your question is Propane
Explanation:
Data
mass of Propane = 3 g
mass of Oxygen = 10 g
limiting reactant = ?
Balanced chemical reaction
C₃H₈ + O₂ ⇒ H₂O + CO₂
Process
1.- Calculate the molar mass of the reactants
C₃H₈ = (12 x 3) + (8 x 1) = 36 + 8 = 44 g
O₂ = 16 x 2 = 32 g
2.- Calculate the theoretical yield C₃H₈ / O₂ = 44/32 = 1.375
3.- Calculate the experimental yield C₃H₈/O₂ = 3/10 = 0.3
4.- Conclusion
The limiting reactant is Propane because the experimental yield was lower than the theoretical yield.
Li20 + MgCl2 → 2LiCl + Mgo
Name the second reactant:
Name the first product:
How many Lithiums on the product side?
Answer:
1. magnesium chloride
2. lithium chloride
3. 2
Explanation:
Know how to figure names (their are rules, be familiar with them)
Count the number
- Hope that helps! Let me know if you need further explanation.
Final answer:
In the reaction Li2O + MgCl2 → 2LiCl + MgO, the second reactant is magnesium chloride (MgCl2), the first product is lithium chloride (LiCl), and there are 2 lithium atoms on the product side.
Explanation:
The chemical reaction you are referring to is Li2O + MgCl2 → 2LiCl + MgO. In compliance with your question:
The second reactant in the equation is magnesium chloride (MgCl2).The first product of this reaction is lithium chloride (LiCl).On the product side, there are 2 lithium (Li) atoms, as indicated by the coefficient in front of LiCl.It's essential to note that in a balanced chemical equation, the number of atoms of each element must be the same on both the reactants and the products side.
Is it possible for a heat transfer system to involve both internal and external convection simultaneously?
Answer:
When the fluid is forced to flow over a surface it is external forced convection. When the fluid is forced to flow in a tube it is Internal forced convection. It is possible to have both Internal and external convection simultaneously as is case of pipe transporting a fluid in a windy area.
