S<span>plit people in two groups of Casodex resistant treatment men (double -blind cross-over study) </span>
<span>50% get Casodex 50 mg ( BICALUTAMIDE 50 MG ) 1 tablet daily + 1 placebo tablet </span>
<span>Casodex is an anti testosterone agent. </span>
<span>50% get Casodex 50 mg 1 tablet daily + 1 Tamoxifen 20 mg tablet </span>
<span>Tamoxifen is an estrogen receptor inhibitor </span>
<span>Compare the results of tumor growth over 1 year's time then reverse the groups without the physician or the patient knowing if they are receiving tamoxifen or the placebo tamxoifen then compare tumor growth results again.</span>
Answer:
None of the options are correct
Explanation:
Ketone is an organic compound with general formula RCOR' ie RC=OR where R and R' are alkyl groups. Example of ketone can be written as:
C—C—C=O—C
Answer:
C₂O₂
Explanation:
Step 1: Given data
- Molar mass of the molecular formula: 56 g/mol
Step 2: Calculate the molar mass of the empirical formula
M(CO) = 1 × M(C) + 1 × M(O) = 1 × 12 g/mol + 1 × 16 g/mol = 28 g/mol
Step 3: Calculate "n"
We will use the following expression.
n = molar mass of molecular formula / molar mass of empirical formula
n = (56 g/mol) / (28 g/mol) = 2
The molecular formula is:
CO × n = CO × 2 = C₂O₂
Answer: The current common definition of an acid and a base is based upon how the substance releases or attracts hydrogen ions (H+). Acids release H+ ions that can turn neutral molecules into positively charged ions, while bases can attract H+ ions from neutral molecules to produce negatively charged ions.
Explanation:
No It is not correct.
Correct oxidation number of hydrogen in NaH,H2 and H2S are:
- Let x be the Oxidation state of ’H’ by oxidation state rule.
x+1 =0 (Sodium has +1 Oxidation state )
x=−1
Therefore, -1 is oxidation number of Hydrogen in NaH.
- The oxidation number of an element's atom in its standard state is zero. As a result, the oxidation number for H2 is zero.
- The hydrogen oxidation number in H2 is +1. As a result, that hydrogen atom can be reduced to lower oxidation states of hydrogen, such as 0 and -1. However, because +1 is the highest oxidation state of hydrogen, the hydrogen atom cannot be reduced any further.
<h3>What is oxidation number?</h3>
In simple terms, the oxidation number is the number assigned to elements in a chemical combination. The oxidation number is the number of electrons that atoms in a molecule can share, lose, or gain when forming chemical bonds with atoms of a different element.
