In CaF2, the oxidation number of Ca is , and that of F is . In H2SO4, the oxidation number of H is , that of S is , and that of O is . In CaSO4, the oxidation number of Ca is , that of S is , and that of O is . In HF, the oxidation number of H is , and that of F is
Answer:
1. The oxidation number of Ca is 2, F is -1 in CaF₂
2. The oxidation number of H is 2, S is 6, O is -8 in H₂SO₄
3. The oxidation number of Ca is 2, S is 6, O is -8 in CaSO₄
4. The oxidation number of H is 1, F is -1 in HF
Explanation:
To get the oxidation number, we need to take the oxidation number of the whole compound 0. Then we need to know the oxidation number of the other elements and we need to take 'x' as the oxidation number of the unknown element.
Example:
In case of CaSO₄,
We can write an equation as-
CaSO₄ = 0
If we need to know the oxidation number of S
We can write the equation like this-
→2+ x+ (-2*4) = 0 (as we know the oxidation number of Ca is 2 as it has two electrons in its last shell which it gives to other elements to form bonds and the oxidation number of O is -2 as it takes 2 electrons to complete its outer shell)
→2+ x+ (-8) = 0
→2+ x- 8 = 0
→x- 6 = 0
→x = 6; which is the oxidation number of S
The following are the oxidation numbers:
In CaF2, the oxidation number of Ca is +2, and that of F is -1.
In H2SO4, the oxidation number of H is +1, that of S is +6, and that of O is -2.
In CaSO4, the oxidation number of Ca is +2, that of S is +6, and that of O is -2.
In HF, the oxidation number of H is +1, and that of F is -1.
What is oxidation number?Oxidation numbers are a way of representing the degree of oxidation (loss of electrons) or reduction (gain of electrons) of an element in a chemical compound. The oxidation number of an element is calculated based on the number of valence electrons (electrons in the outermost energy level of an atom) and the rules for assigning oxidation numbers.
In general, the oxidation number of an element is equal to the charge it would have if all the bonds in the compound were ionic (made up of positive and negative ions). This allows chemists to predict the behavior of elements in a compound and to balance chemical equations.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything
The question is incomplete,below is the complete question.
Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"
You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."
QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?
Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.
The proximal convoluted tubule is A. lined with epithelial cells that lack microvilli. B. the site of glucose and amino acid reabsorption. C. permeable to water if ADH is present. D. impermeable to water. E. the site of water secretion.
Answer:
The correct answer is - option B.
Explanation:
The proximal convoluted tubule or PCT is the the part of nephron that lies in between of loop of Henle and bowman's capsule. The PCT is responsible for the most amount reabsorption of sodium, glucose, amino acids, water, potassium and chloride and reabsorbs around 65% to 100% of filtered substance.
Epithelial cells in the PCT reabsorb substances that have nutritional importance by the numerous microvilli on their surface.
Thus, the correct answer is - option B.

Evaluate this statement: Gene flow increases the genetic divergence of populations. Evaluate this statement: Gene flow increases the genetic divergence of populations. This statement is true. This statement is false. Gene flow is not able to influence the genetic divergence of populations. This statement is false. Gene flow reduces the divergence of populations. This statement is false. Gene flow increases the number of genes in populations.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
Explanation:
In biology and related areas, genetic divergence occurs if populations with a common ancestor develop unique traits, which are the result of genetic changes over time. On the other hand, gene flow occurs when traits including genes flow from one population to another, usually because the populations are in contact. In this context, gene flow reduces divergence because if genetic material flows between populations is less likely each population can develop unique traits, instead the populations involved will have similar traits after some time.
The correct answer is C. This statement is false. Gene flow reduces the divergence of populations.
The following information should be considered;
In terms of biology and related areas, genetic divergence arise at the time when the populations are with a common ancestor that created unique traits, due to this there are genetic changes over time. While gene flow arise at the time when traits involved genes flow from one population to another, normally due to the populations are in contact. In this given situaton, gene flow reduces divergence since genetic material flows between populations is less likely every population can create unique traits, rather the populations involved will have similar traits.Learn more: https://brainly.com/question/5303391?referrer=searchResults

Answer:
D
Explanation:
While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.
What is an experiment?The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.

Cómo explicarías tu que el soporte vegetal es más importante que los animales en un ecosistema?
Answer:
Las plantas son productores primarios, mientras que los animales son consumidores
Explanation:
La cadena alimenticia está conformada por niveles tróficos donde la energía fluye desde los niveles basales representados por la base de la pirámide, hasta los niveles superiores (pico de la pirámide). De este modo, los organismos representan diferentes eslabones de acuerdo a su posición en la cadena alimenticia. En el primer nivel se encuentran los productores primarios como lo son, por ejemplo, las plantas y algas de ambientes terrestres y acuáticos, respectivamente, siguiendo por los consumidores primarios (por ejemplo, especies hervívoras), continuando sucesivamente por los consumidores secundarios, terciarios y cuaternarios (especies carnívoras), los cuales se encuentran en posiciones cada vez más altas de la pirámide. No obstante, es importante indicar que existen ocasiones donde los consumidores superiores (ya sea secundarios, terciarios y cuaternarios) se alimentan de especies situadas por debajo de diferentes niveles no consecutivos e incluso también de especies pertenecientes al mismo nivel trófico, con lo cual encajando en más de una categoría y dificultando su clasificación en la cadena.

A scientific law can become a scientific theory, but a scientific theory cannot become a scientific law. 4.) A scientific theory cannot become a scientific law, and a scientific law cannot become a scientific theory.
Answer:
It's true.
Explanation:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
When the scientists test the idea, they develop a theory by following a set of logical steps. A theory becomes a scientific law once it has been rigorously examined and accepted. Thus, option A is correct.
What A scientific theory can become a scientific law?One prevalent fallacy is the idea that hypotheses eventually become laws. Despite the number of supporting examples, hypotheses do not actually become laws after repeated testing.
Scientific laws, like theories, explain occurrences that the scientific community has determined to be verifiably true. In general, laws explain what will occur in a specific circumstance and are proven by a mathematical equation, whereas theories explain how the phenomenon occurs.
Therefore, A testable explanation of a natural event is what constitutes a scientific hypothesis. The concept of gravity, for instance, explains why an apple always falls to the ground when.
