Explanation:
I HOPE IT HELPS :)
<u>Answer:</u>
1. In Glucose: C : H : O = 1 : 2 : 1
2. In Sulfuric acid: H : S : O = 2 : 1 : 4
3. In Butene: C : H = 1 : 2
<u>Explanation:</u>
Mole ratio is defined as the ratio of amounts in moles present in a compound. Simplest mole ratio basically means that the moles are present in the least whole number ratio.
- In Glucose,
Moles of Carbon atom = 6
Moles of Hydrogen atom = 12
Moles of Oxygen atom = 6
Mole ratio of the atoms: C : H : O :: 6 : 12 : 6
Making this, the simplest mole ratio C : H : O = 1 : 2 : 1
- In Sulfuric acid,
Moles of Sulfur atom = 1
Moles of Hydrogen atom = 2
Moles of Oxygen atom = 4
Mole ratio of the atoms: H : S : O = 2 : 1 : 4
- In Butene,
Moles of Carbon atom = 4
Moles of Hydrogen atom = 8
Mole ratio of the atoms: C : H = 1 : 2
Answer:
Experiment Question, Independent & Dependent Variable, Null & Alternate Hypothesis
Explanation:
Experiment Question : Whether fine cloth coverage over chicken jars effect flies & their eggs in ambience ?
Independent Variable : The causal variable, ie cloth cover existence on the chicken jar
Dependent Variable : The resultant variable, ie presence of flies & their eggs near jar, meat
Null Hypothesis [H0] : Cloth cover on chicken jar doesn't effects flies' & eggs' presence around jar, chicken.
Alternate Hypothesis [H1] : Cloth cover on chicken jar effects flies' & eggs' presence around jar, chicken.
