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
Answer:
Correct option would be A. Mg(s) → Mg2+ + 2e-
Explanation:
Marked as correct answer on Quiz ;) (A P E X)
The elements are identified by its aomic number and they are placed in the periodic table in ascending order of atomic number.
There is one unique element for a given atomic number.
For example, atomic number 1 identifies Hydrogen and there cannot be another different element with the same atomic number.
All the elements with atomic numbers from 1 to 118 have been discovered. So, you know that there is not room for new products with atomic number equal or less than 118.
Answer:
2 M Al³⁺(aq) and 6 M NO₃⁻(aq)
Explanation:
Al(NO₃)₃ is a strong electrolyte that ionizes according to the following equation.
Al(NO₃)₃(aq) → Al³⁺(aq) + 3 NO₃⁻(aq)
The solution 2.0 M contains 2.0 moles of Al(NO₃)₃ per liter of solution.
The molar ratio of Al(NO₃)₃ to Al³⁺ is 1:1. The concentration of Al³⁺ is:
2.0 mol Al(NO₃)₃/L × (1 mol Al³⁺/1 mol Al(NO₃)₃) = 2.0 mol Al³⁺/L = 2.0 M Al³⁺
The molar ratio of Al(NO₃)₃ to NO₃⁻ is 1:3. The concentration of NO₃⁻ is:
2.0 mol Al(NO₃)₃/L × (3 mol NO₃⁻/1 mol Al(NO₃)₃) = 6.0 mol NO₃⁻/L = 6.0 M NO₃⁻
Answer:
WAS THE VOOK NAME =THE BOY WHO HARNESSED THE WIND?
1.How did environmental factors affect food production? They could not grow any crops
2. What does William’s windmill allow him to have that he didn’t before? How does life change for him and his family? His windmill allowed him and his family to be able to regrow crops and have unlimited water. Life changes because don’t have to worry about drought issues.
3.Why are trees important to farmers in William’s village? The trees are important because they stop floods. Now whenever it rains the trees can soak up the water.4.Could you imagine living without electricity? What would your life be like? Describe William's life and compare it to American teenagers and even your own. I could not imagine living without electricity. If I lived without electricity, I think my life would be kind of hard at first but after a while I would have to get used to it. William had to depend on the sun for all his light a normal teenager can cut the lights on and off in
