Answer:
137,000 watts
Explanation:
1 kilowatt = 1000 watts
137 kilowatts = 1000 × 137 watts
= 137,000 watt
C the products are on the right side of the arrow
Answer:
(A) 0.4M NaOH
Explanation:
The 20M NaOH caustic soda is diluted from 10mL to 500mL, that is:
500mL / 10mL = Is diluted 50 times.
That means we can solve the new concentration of the diluted solution dividing the stock concentration (20M) 50 times:
20M / 50 = 0.4M NaOH is the concentration of the diluted NaOH solution.
Right answer is:
<h3>(A) 0.4M NaOH</h3>
Answer:
Explanation:
Combination Reaction: is a reaction that occurs when two or more reactants combine to form a single new products. The reactants can either be Elements or Compounds. It does not require heat during the reaction.
A + B ---------> C
C (s) + O2 (g) ----------> CO2 (g)
CaO (s) + H2O (l) ---------> Ca(OH)2 (s)
In this reaction, energy is released.
Decomposition Reaction: is a reaction that occurs when a a single reactant is broken down to form two or more products. Application of heat is usually required in this type of reaction.
Δ
AB ---------> C + D
Δ
CaCO3 (s) --------> CaO (s) + CO2 (g)
In this reaction, energy is absorbed.
