Answer:

oxygen ?

Explanation:

not sure but I think so

Aerobic cellular respiration requires an adequate supply of oxygen. In the presence of oxygen, the cell completely oxidised the glucose molecule to form ATP.

In cellular respiration, the cell takes glucose and breaks it down to form energy. Cellular respiration is of two types: aerobic respiration and anaerobic respiration.

In aerobic respiration, the cell requires oxygen. Due to the presence of oxygen, the complete oxidation of glucose takes place. Glucose is converted into pyruvic acid and then enters the Krebs cycle and the electron transport chain to make ATP.

In the aerobic cellular respiration process, the maximum amount of ATP is derived. In anaerobic respiration, the cell performs respiration without the presence of oxygen. An example is glycolysis.

In this glycolysis process, the complete oxidation of glucose does not take place. In the absence of oxygen from pyruvate, lactic acid and ethanol are produced. This is called fermentation.

Hence, for aerobic cellular respiration, oxygen is required.

Answer:

D. 4:3

Explanation:

The mole ratio is simply the coefficients in a balanced chemical reaction and their relation to each other. For example, the mole ratio between Al and [tex]Al_{2}O_{3}[/tex] is 2:1, and the ratio between [tex]O_{2}[/tex] and [tex]Al_{2}O_{3}[/tex] is 3:2.

Answer:

We assume you are converting between moles CO2 and gram. You can view more details on each measurement unit: molecular weight of CO2 or grams This compound is also known as Carbon Dioxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles CO2, or 44.0095 grams.

Answer:

Assuming the question was about 3 mol CO2 - it's 132g. Assuming it's about CO - it's 84g.

Explanation:

The molar mass of X means "a mole of X weighs that".

So 1 mol CO2 weighs 44g, so 3 moles will weigh three times that - 132g.

Now, with CO, we need to compute the molar mass of CO. One particle of CO is comprised of 2 atoms - a Carbon atom and an Oxygen atom, with molar masses ~12g and ~16g respectively. That brings us to molar mass of CO of 28g and the mass of 3 mol CO of 28g*3 = 84g

Santos and Luderitz have a difference in the temperature despite being at the same distance from the equator because of the oceanic currents, and the topographical factors.

Oceanic currents are the directional movement of the oceanic and the seawater by the Coriolis Effect, density, sea level, and gravity, these movements affect the temperature of the area.

The sea level and the oceanic currents play a role in determining the temperature of the region as it affects the humidity, warm and cold wind, and environmental and other topographical factors.

Therefore, the difference in oceanic currents results in different temperatures.

Answer: i would say D or the last one.

Explanation: According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

Answer:

True.

Explanation:

Yes, all systems disperse their energy spontaneously because all types of  energy spontaneously flows from concentrated to dispersed if it is not hindered by any material in their way. Energy can be prevented from spreading by materials such as containers. If there is no substance in the path of energy so it can disperse automatically from a concentrated region to a lower region.

Answer: 11.0 g of calcium will react with 10.0 grams of water.

Explanation:

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

moles of [tex]H_2O[/tex]

[tex]\text{Number of moles}=\frac{10.0g}{18g/mol}=0.55moles[/tex]

The balanced chemical equation is:

[tex]Ca+2H_2O\rightarrow Ca(OH)_2+H_2[/tex]

According to stoichiometry :

2 moles of [tex]H_2O[/tex] require = 1 mole of [tex]Ca[/tex]

Thus 0.55 moles of [tex]H_2O[/tex] require=[tex]\frac{1}{2}\times 0.55=0.275moles[/tex]  of [tex]Ca[/tex]  

Mass of [tex]Ca=moles\times {\text {Molar mass}}=0.275moles\times 40g/mol=11g[/tex]

Thus 11.0 g of calcium will react with 10.0 grams of water.

grams => moles => divide by formula weight

moles => grams => multiply by formula weight

a. 6.7 grams NaOH = 6.7g/40g/mol = 0.17 mole

b. 2.5 moles CaCO₃ = 2.5 moles x 100g/mol = 250 grams

Answer:

13g

Explanation:

The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction.

Therefore, if the total mass of the products is 30g, that means that the reactants have a mass of 17g + the other reactant to = 30g.

30g - 17g = 13g

Answer:

Option D.

Explanation:

Percentage yield = Actual yield / Theoretical yield * 100%

Actual yield = 11.0 grams

Theoretical yield = 12.3 grams

Percentage yield = 11.0 / 12.3  *  100

Percentage yield = 89.43%
