Answer:
The answer to your question is: 3000 cm
Explanation:
30 meters long to cm
We can use a rule of three to solve it
We know that 1 meter ------------------ 100 cm
30 meters ---------------- x
x = 30(100)/1 = 3000 cm
Four half lives have passed because the amount is cut in half each time
Answer:
1.8 moles of NaCl must be produced.
Explanation:
Based on the reaction:
HCl + NaOH → NaCl + H2O
<em>1 mol of HCl reacts with 1 mol of NaOH to produce 1mol of NaCl</em>
<em />
To solve this question we must find, as first, the <em>limiting reactant:</em>
<em />
1.8 moles of HCl will need 1.8 moles of NaOH for a complete reaction (Ratio of reaction 1:1). As there are 3.3 moles of NaOH,
<em>HCl is limiting reactant</em>
<em />
When the 1.8 moles of HCl react completely,
1.8 moles of NaCl must be produced because 1 mole of HCl produce 1 mole of NaCl
Answer:
6 number of complete triglycerides that could be formed .
Explanation:
In 25 microseconds ,single fatty acid attachment to glycerol takes place.
So, in 1 microseconds =
If the enzyme catalyzes dehydration synthesis reactions for 450 microseconds, then maximum numbers of attachments of fatty to glycerol will be:
And each triglycerides has three fatty acid chains.So, number of triglycerides formed will be :
6 number of complete triglycerides that could be formed if no fatty acids were bonded to glycerol at the beginning of the reactions
Answer:
z+4
Explanation:
An isotope of an element, atomic number Z, has a mass number 2z+4. How many neutrons are there in the nucleus of the element?o
protons + neutrons =mass number
so
z +neutrons = 2z+4
neutrons = 2z+4 - z=z+4 which is the # of neutrons in the nucle
