Answer:
Only reaction 1
Explanation:
C + O2 → CO
the charge of C in CO is +2 (oxidation)
from 0 to +2
the charge of O in CO is -2 (reduction)
from 0 fo -2
Hence it is a redox (reduction-oxidation) reaction
This is also valid for,
C + O2 → CO2
the charge of C in CO2 is +4 (oxidation)
charge increases from 0 to +4
the charge of O in CO2 is -2 (reduction)
charge decreases from 0 to -2
hence, it is a redox reaction
K2SO4 + CaCl → KCl + CaSO4
none of the charges changes in this reaction
please recheck, for this may not be the correct answer
Answer:
During Glycolysis, there is one step where NADH + H+ is formed from NAD+ O F-6-P - F- 1,6-BP O PGAL – 1,3-BPGA O 2-PGA - PEP O 3-PGA → 2-PGA.
Answer:
Ca + AlCl3 = CaCl2 + Al - chemical equation balancer.
Explanation:
Answer:
The new pressure is 2, 74 atm
Explanation:
We apply Boyle Mariotte's law, where for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2 P2=( P1 x V1)/V2 1 L-----1000L--->( 140ml/1000ml)x1L=0,140 L
(50ml/1000ml)x 1L =0,050L
P2= (0,980 atm x 0,140 L)/0,050L= 2, 744 atm
