For the rocket engine a lean or excessively rich air-fuel ratio will lead to a compromise in the power output and ultimately the altitude the rocket will reach. Hence which ever the ratio the altitude is greatly affected, unless the ideal ratio is archived.

The air-fuel ratio is the ratio of the amount of air need to burn a part of fuel in a combustion cycle, the ratio is basically a compromise between fuel economy and optimum power output.

For a gasoline engine for example, the ideal air-fuel mixture of 14.7 parts air to 1 part fuel.

Which components make up bronfenbrenner's ecological theory?

Bronfenbrenner divided the person's environment into ﬁve diﬀerent systems:

microsystem
mesosystem
exosystem
macrosystem
chronosystem.

What is bronfenbrenner's ecological theory?

Bronfenbrenner's ecological systems theory views child development as a complex system of relationships affected by multiple levels of the surrounding environment, from immediate settings of family and school to broad cultural values, laws, and customs.
To study a child's development then, we must look not only at the child and her immediate environment, but also at the interaction of the larger environment as well.
The microsystem is the most inﬂuential level of the ecological systems theory.
This is the most immediate environmental settings containing the developing child, such as family and school.
Bronfenbrenner's ecological systems theory has implications for educational practice.

Which of the following is an oxidation-reduction reaction? Which of the following is an oxidation-reduction reaction? Ba(C2H3O2)

DochEvi [55]

Answer:

The only oxidation- reduction reaction is Cu (s) + 2AgNO3 (aq) → 2Ag (s) + Cu(NO3)2

Explanation:

An oxidation-reduction reaction is a chemical reaction that involves an electron transfer between two species. This will lead to a change in oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Some atoms have different possible oxidation numbers.

H has oxidation number +1

O has oxidation number -2

The oxidation number of an individual atom is 0.

The total oxidation number of all atoms in: a neutral species is 0 and in an ion is equal to the ion charge.

⇒ Ba(C2H3O2)2 (aq) + Na2SO4 (aq) → BaSO4 (s) + 2NaC2H3O2

(C2H3O2)2 has an oxidation number of -2. So Ba has an oxidation number of +2

In BaSO4 has SO4 an oxidation number of -2 and Ba has an oxidation number of +2

This means Ba doesn't change its oxidation number.

In Na2SO4 Na has an oxidation of +1; in NaC2H3O2 Na has an oxidation of +1

This means Na doesn't change its oxidation number.

⇒ Cu (s) + 2AgNO3 (aq) → 2Ag (s) + Cu(NO3)2

Cu has an oxidation number of 0

In Cu(NO3)2, NO3 has an oxidation number of -1 so Cu has an oxidation number of +2

In 2AgNO3, NO3 has an oxidation number of -1 so Ag has an oxidation number of +1

Ag has an oxidation number of 0

⇒ HCl (aq) + NaOH (aq) → H2O (l) + NaCl

The oxidation number of Cl and Na do not change

⇒ AgNO3 (aq) + HCl (aq) → AgCl (s) + HNO3

In AgNO3 Ag has an oxidation number of +1

In AgCl Ag has an oxidation number of +1

In HCl Cl has an oxidation number of -1

In AgCl Cl has an oxidation number of +1

The oxidation number of Cl and Ag do not change

⇒ H2CO3 (aq) + Ca(NO3)2 (aq) → 2HNO3 (aq) + CaCO3 (s)

In Ca(NO3)2 Ca has an oxidation number of +2

In CaCO3 Ca has an oxidation number of +2

In Ca(NO3)2 N has an oxidation number of +5

In HNO3 N has an oxidation number of +5

In H2CO3 C has an oxidation number of +4

In CaCO3 C has an oxidation number of +4

The only oxidation- reduction reaction is Cu (s) + 2AgNO3 (aq) → 2Ag (s) + Cu(NO3)2

Oxidizing agent: Ag ; Reducing agent: Cu

The amount of fat recommended for somone with a daily diet of 2000 Calories is 65 g. What percent of the calories in this diet w

Doss [256]

Answer:

29.575%

Explanation:

Data provided:

Calories taken in daily diet = 2000

Recommended amount of fat = 65 grams

Average number of calories for fat = 9.1 calories / g

Thus,

Number of calories in the diet with average number of calories for fat

= Recommended amount of fat × Average number of calories for fat

= 65 × 9.1

= 591.5 calories

Therefore,

the percentage of calories in his diet supplied = ( 591.5 / 2000 ) × 100

= 29.575%
