Answer:
The yeast respired aerobically
Explanation:
The expectation here was that the yeast was going to put the sugar in the grape juice through fermentation, which is an anaerobic process that results in alcohol as one of the products. However since no alcohol was found in this particular example, it is fair to assume that maybe there was oxygen in teh muxture and therefore the yeast respired aerobically, producing water and carbon dioxide as products.
Observation is acknowledging and noting some facts from the surroundings or the environment. Usually, observation is done using the five senses of human such as the sense of sight, sense of smell, sense of touch, sense of hearing and sense of tasting. It can also be qualitative and quantitative. Qualitative observations are those who use non-numeric forms in expressing the observation however quantitative uses numeric forms in presenting the observation. Inference on the other hand is the probable explanation or interpretation based on the observation given. Therefore, the statement "The container is filled to the 350 ml mark with water " is an observation.
The answer is mass.
Mass is the amount of matter in an object. So no matter where the object is, it mass will stay the same unless particles are increased.
Answer:
The answer to your question is Rb₃N
Explanation:
Data
Lithium Nitride = Li₃N
Rubidium Nitride = ?
Process
1.- Both Lithium and Rubidium are placed in group lA of the periodic table, which means that their valence number if + 1.
2.- Nitrogen is placed in group VA, which means that its oxidation number is -3.
3.- Write the formula and interchange the oxidation numbers.
Rb⁺¹ N⁻³
Rb₃N₁
But number one is not necessary to write it.
Rb₃N
