the double helix is hydrogen bonded through the bases only so the bases are inside the helix only
as adenine combines with thymine and guanine with cytosine
phosphate are in the exterior of it
sugar groups constitute the double helix.
Answer:
0.01504 mol/dm3
Explanation:
Calcium Hydroxide - Ca(OH)2
Hydrochloric acid - HCl
The reaction between both is given as;
2HCl + Ca(OH)2 --> CaCl2 + 2H2O
2 : 1
The relationship between the concentration and volume is given as;
CaVa / CbVb = na / nb
where a = acid (HCl) and b = base Ca(OH)2
Inserting the values;
0.04 * 18.8 / (Cb * 25) = 2 / 1
0.752 / 25Cb = 2
Cb = 0.752 / 50 = 0.01504
Answer:
<h2>5080 mL</h2>
Explanation:
The volume of the gas at standard pressure can be found by using the formula for Boyle's law which is
Since we are finding the new volume
From the question we have
We have the final answer as
<h3>5080 mL</h3>
Hope this helps you
Answer:
0.46 L
Explanation:
In order to solve this problem we need to keep in mind the following <em>definition of molarity</em>:
- Molarity = Number of moles / liters
We now <u>input the given number of moles and molarity</u>:
- 9.4 M = 4.36 mol / liters
And <u>calculate how many liters are required</u>:
- liters = 4.36 mol / 9.4 M
