1. CO₃²¯ is a reactant
2. H₂O is a product
3. CO₂ is a product
4. The 2 in front of H⁺ is a coefficient.
Chemical equation generally comprises of reactants and products.
- The reactants are located on the left while the products are located on the right side.
- The coefficients are numbers written where necessary before each reactants or products in order to balance the chemical reaction.
With the above information in mind, we can obtain the answers to the question as follow:
2H⁺ + CO₃²¯ —> H₂O + CO₂
From the above equation, we can conclude as follow:
- The 2 in front of H⁺ is a coefficient.

Here is the full question
E = 420 − 7
s The elevation, E , in meters, of a skydiver s seconds after parachute activation is given by the equation above. What is the best interpretation of 420 as shown in the equation?
a) The skydiver started diving at an elevation of 420 meters.
b) The skydiver activated the parachute at an elevation of 420 meters.
c) The skydiver took 420 seconds after parachute activation to reach the ground.
d) The skydiver's elevation decreased by 420 meters per second after parachute activation.
Explanation:
Answers is that The skydiver's elevation decreased by 420 meters per second after parachute activation.
C- The reason why is because if you cant see him, theres a high chance he wont be able to see you, thus he is blind into seeing you
Answer:
The balanced equation for reaction of solid cesium with liquid water
= 2Cs + 2H2O → 2CsOH + H2
Explanation:
cesium react with liquid water to produce cesium hydroxide and hydrogen gas
that is 2 moles of Cs react 2 moles of H2O to form 2 moles CsOH and 1 of hydrogen gas
