Answer:
Explanation:
It makes sense because Helium and Hydrogen only hold 1 and 2 subsequent protons/neutrons and electrons. When the Big Bang happened the entire universe was so hot that it was impossible for elements to form since it was impossible for electrons to stay bound to the atoms. After a few seconds the universe began to cool enough for electrons to bond to atoms and create different elements. Since Helium and Hydrogen have 1 and 2 electrons subsequently we can assume that they were the first elements to be created. Also they are the most abundant elements in the Universe which backs up this theory.
The awnser is Hydrogen. It had the greatest average atomic mass
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
The zone and its characteristics include the following:
- Subpolar low: Lies along the polar jetstream.
- Horse latitudes: The trade winds and westerlies originate here.
- Doldrums: Heavy precipitation, little wind.
<h3>What is Horse latitude zone?</h3>
This is referred to regions which is located at about 30 degrees north and south of the equator and forms the basis of westerlies.
The other zones such as doldrums are also found at the equator with their respective features and can be seen above. This therefore makes it the most appropriate choice.

Answer:
The equilibrium will shift in forward direction.
Explanation:
The equilibrium between the carbonic acid and bicarbonate ion is shown below as:
H₂CO₃ (aq) ⇔ H⁺(aq) + HCO₃²⁻(aq)
According to Le Chatelier's Principle, the change in any state of the equilibrium say temperature, volume, pressure, or the concentration, the equilibrium will oppose these changes and will shift in such a way that the effect cause must be nullified.
<u>If a strong base is added to the equilibrium, the base will accept hydrogen ions which are formed in the right side of the equilibrium. Thus, there will be less hydrogen ions present and to compensate this effect, the equilibrium will shift in forward direction.</u>
