Answer:
266.5°C
Explanation:
Because you have to subtract them to get your final answer of 266.5°C
Answer:
42000km
Explanation:
Average Speed (v) can be calculated using the formula as follows:
Average speed = distance (d) ÷ time (t)
According to this question, a space shuttle travels around the Earth at a constant speed of 28000 km/hr in 90 minutes.
Since 60 minutes = 1 hr
90 minutes = 90/60
= 3/2 or 1.5hours.
Using speed = distance/time
Distance (km) = speed × time
Distance = 28000 km/hr × 1.5hr
Distance = 42000km
Answer:
Given Data:
mass of solute= 0.2
volume of solution: 250ml
Normality=?
Explanation:
250ml =0.25dm3 <em> Volume</em>
m.mass of NaOH= 40g/mol
Equivalent weight of solute=40/1 =40
N=mass in g of solute/equivalent weight of solute*Volume of solution
N=0.2/40*0.25
N= 0.02
During the first step of a redox reaction, the enzyme dehydrogenase strip hydrogen atoms from organic fuel.
<h3>WHAT IS AN ENZYME?</h3>
An enzyme is a biological catalyst that regulates the rate of a chemical reaction. Enzymes are of different types and are specific in function.
Dehydrogenase is a specific kind of enzyme that reduces/oxidizes molecules by removing or adding hydrogen atoms in the molecule.
Therefore, during the first step of a redox reaction, the enzyme dehydrogenase strip hydrogen atoms from organic fuel.
