Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
Answer:
The answer to your question is Single replacement
Explanation:
Data
Chemical reaction
Na + H₂O ⇒ NaOH + H₂
Single replacement is a chemical reaction in which a metal replaces the cation of a compound.
Decomposition is a chemical reaction in which a compound forms 2 or more products.
Double replacement in this chemical reaction two compounds react interchanging their cations and anions.
Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.
Answer:
Z negative
Explanation:
The negative charge shows that this is an electron. Electrons are present outside the nucleus of the atom and having negative charge. Usually represented by e-
Answer:
The answer to your question is 23.4 moles of Glucose
Explanation:
Data
moles of Oxygen = ?
moles of glucose = 3.9
-Balanced chemical reaction
1C₆H₁₂O₆ + 6O₂ ⇒ 6H₂O + 6CO₂
Process
1.- To solve this problem, use the coefficient of the balanced chemical equation, and use proportions and cross multiplication.
1 mol of C₆H₁₂O₆ -------------------- 6 moles of O₂
3.9 moles of C₆H₁₂O₆ ------------------ x
x = (3.9 x 6 ) / 1
x = 23.4 moles
2.- Conclusion
3.9 moles of glucose consume 23.4 moles of oxygen
Answer:
Biodiversity will decrease.
Explanation:
The likely result of clearing the fields for building homes is that biodiversity will decrease.
Biodiversity is the variation in life forms within a particular area.
- The balance of the ecosystem is easily tripped by the influence of human activities.
- Some habitats are easily destroyed when new fields are cleared.
- Habitat loss is huge problem, in the ecosystem as a result of human activities.
