Answer:
Cardiac output (CO) = 8.54 l / min
Explanation:
Given:
Oxygen consumption (V) = 1.41 l O2/min
Oxygen in arterial (Ca) = 190 ml O2/L = 0.19 l O2/L
Oxygen in venous (Cv) = 25 ml O2/L = 0.025 l O2/L
Find:
Cardiac output (CO)
Computation:
Cardiac output (CO) = V / (Ca - Cv)
Cardiac output (CO) = 1.41 / (0.19 - 0.025)
Cardiac output (CO) = 8.54 l / min
You just look at what vertical row that silicon is, and every element that is in the same vertical row as silicon will have the same lewis dot structure...and this applyes for most elements on the periodic table of elements.
- C, Ge,Sn, Pb:
all these elements are in the same column, and therefore have the same number of valence electrons
Answer:
A new type of technology that uses stem cells to grow body parts is called stem cell scaffolding.
Explanation:
"In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma, and multiple myeloma. These transplants use adult stem cells or umbilical cord blood." - Mayo Clinic

Answer:
Hydrogen and chlorine need to be balanced. There is an equal amount of magnesium on each side.
Explanation:
The given chemical equation does not hold the law of conservation of mass because the number of atoms of hydrogen and chlorine are not balanced on each side.
Chemical equation:
Mg + HCl → MgCl₂ + H₂
Balanced chemical equation:
Mg + 2HCl → MgCl₂ + H₂
Now this equation hold the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
