Carbonic acid ---> water + carbon dioxide
so it's the second option
Answer:
Using the smallest coefficient the chemical equation is written as
3KOH(aq) + H3PO4(aq) → K3PO4(aq) + 3H2O(aq)
Explanation:
Neutralization reaction is a reaction in which acid and base reacts quantitatively to form salt and water.
Base = potassium hydroxide
acid = phosphoric acid.
KOH =potassium hydroxide
H3PO4 = Phosphoric acid
KOH(aq) + H3PO4(aq) → K3PO4(aq) + H2O(aq)
The number of atoms on both side (reactant and product) of the equation are not equal so, we need to balance it.
3KOH(aq) + H3PO4(aq) → K3PO4(aq) + 3H2O(aq)
The product are salt and water.
Salt = K3PO4
water = H2O
The equation is balanced on both sides .
The potassium atom is 3 on both sides , oxygen atom is 7 on both sides, hydrogen atom is 6 on both sides and phosphorus atom is 1 on both sides.
Answer:
8.2 x 106^-11
Explanation:
To begin this problem you must remember the basic rule of scientific notation, which is, must be between 1-10. .000000000082 is much smaller than 1. However by moving the decimal 11 spots to the right, we can make it 8.2
Continue to move the decimal to the right until the value is in the 1-10 range. Make sure to count the moves to the right.
Once the decimal is in the right spot count the spots moved.
Since the number is wayyy smaller than the answer given the number will be negative 10^-11, in order to make it what is was before.
Answer:
ion exchange
Explanation:
because in the time period of chemical reactions it product ion
Answer:
A). Collapse, condensation, accretion, clearing.
Explanation:
Planetesimals are described as the small solid astronomical objects which are the building blocks for the formation of solid planets. Accretion is described as the process in which the solid astronomical objects cluster to form larger objects that eventually leads to the formation of planets.
As per the question, the correct order of processes that are followed in this accretion process would be a collapse, condensation, accretion, clearing. First occurs the collapse of a nebula followed by condensation of cosmic dust grains. <u>After this, the accession or accumulation of solid parts takes place to form larger objects and this is immediately followed by the clearing of debris and dust to allow planets to form</u>. Thus, <u>option A</u> is the correct answer.
