Answers

Answer:

See Explanation

Explanation:

i) The equation of the dissolution of BF2 is;

BaF2(s)⇄Ba2+(aq)+2F-(aq)

ii) Ksp =[Ba2+]  [2F-]^2

iii) Let the concentration/solubility of [Ba2+] and [2F-] be x

Ksp = [x] [2x]^2

Ksp = 4x^3

iv) x =∛Ksp/4

O B. a phase change
C. a nuclear reaction
D. a destruction of mass

Answers

B.) a phase change. I think but for sure it’s not C-

The most likely to take place when a solid is placed in a liquid at room temperature ( i.e. 20°C ) is ; ( A )  A chemical reaction

Although your question lacks the required diagram a general answer is provided within the scope of your question

When a solid at 20°C is placed inside a liquid also at 20°C  in the laboratory the emergence of gas bubbles shows that there has been a chemical change between the solid and liquid reactant ( i.e. a chemical reaction has taken place ).

Hence we can conclude that what is most likely to have taken place in this situation is a Chemical reaction.

How are these two formulas called?

Thank youu​

Answers

These are structural formulas of constitutional isomers of hexene, an alkene.

Both are acyclic, six-carbon chains, and they differ only in the position of the double bond. As constitutional isomers, both structures have the same molecular formula.

The first structure is of hex-1-ene (or 1-hexene).

The second structure is of (3E)-hex-3-ene [or (3E)-3-hexene].

Both structures have the molecular formula C₆H₁₂.

I hope I answered your question. Please feel free to let me know otherwise.

Explanation:

Freon, a very useful refrigerant, is produced in the following reaction:
3CCl4 (g) + 2SbF3 (s) → 3CCl2F2 (g) + 2 SbCl3 (s)
If a chemist wants to make 3.0 x 106 moles of Freon using excess carbon tetrachloride, how many moles of antimony trifluoride will the chemist need?

Answers

Answer:

The chemistry will need 2*10⁶ moles of antimony trifluoride.

Explanation:

The balanced reaction is:

3 CCl₄ (g) + 2 SbF₃ (s) → 3 CCl₂F₂(g) + 2 SbCl₃ (s)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

CCl₄: 3 moles  SbF₃: 2 moles CCl₂F₂: 3 molesSbCl₃: 2 moles

You can apply the following rule of three: if by reaction stoichiometry 3 moles of freon are produced by 2 moles of antimony trifluoride, 3*10⁶ moles of Freon are produced from how many moles of antimony trifluoride?

[tex]moles of antimony trifluoride=\frac{3*10^{6} moles of freon*2 moles of antimony trifluoride}{3 moles of freon}[/tex]

moles of antimony trifluoride= 2*10⁶

The chemistry will need 2*10⁶ moles of antimony trifluoride.

If the sun output of solar radiation increased by 20% how would this impact the temperature of earth's mantle

Answers

Answer:

The temperature will not be affected directly

Explanation:

The solar radiation has a direct effect on the outer surface and inner part of the earth but  an increase by 20% of the solar radiation will not cause the temperature of the Earth's mantle to increase because the factors that heat up the Earth's mantle are : Friction between core materials that sink into the center of the planet and Heat from decay of radioactive materials

The thirteen colonies became states at the end of the Revolutionary War.O TrueO False Please read the short story "Sleeping" By Katharine Weber. Once you have finished, you will write your ideas down to continue the writing prompt avaliable at the end of the story.SleepingBy Katharine WeberShe would not have to change a diaper, they said. In fact, she would not have to do anything at all. Mrs. Winter said that Charles would not wake while she and Mr. Winter were out at the movies. He was a very sound sleeper, she said. No need to have a bottle for him or anything. Before the Winters left they said absolutely please not to look in on the sleeping baby because the door squeaked too loudly.Harriet had never held a baby, except for one brief moment, when she was about six, when Mrs. Antler next door had surprisingly bestowed on her the tight little bundle that was their new baby, Andrea. Harriet had sat very still and her arms had begun to ache from the tension by the time Mrs. Antler took back her baby. Andy was now a plump seven-year-old, older than Harriet had been when she held her that day.After two hours of reading all of the boring mail piled neatly on a desk in the bedroom and looking through a depressing wedding album filled with photographs of dressed-up people in desperate need of orthodonture (Harriet had just ended two years in braces and was very conscious of malocclusion issues) while flipping channels on their television, Harriet turned the knob on the baby's door very tentatively, but it seemed locked. She didnt dare turn the knob with more pressure because what if she made a noise and woke him and he started to cry?She stood outside the door and tried to hear the sound of a baby breathing but she couldnt hear anything through the door but the sound of the occasional car that passed by on the street outside. She wondered what Charles looked like. She wasnt even sure how old he was. Why had she agreed to baby-sit when Mr. Winter approached her at the swim club? She had never seen him before, and it was flattering that he took her for being capable, as if just being a girl her age automatically qualified her as a baby-sitter. By the time the Winters came home, Harriet had eaten most of the M & M's in the glass bowl on their coffee table: first all the blue ones, then the red ones ,then all the green ones, and so on, leaving, in the end, only the yellow.They gave her too much money and didnt ask her about anything. Mrs. Winter seemed to be waiting for her to leave before checking on the baby. Mr. Winter drove her home in silence. When they reached her house he said, My wife. He hesitated, then he said, You understand, don't you? and Harriet answered Yes without looking at him or being sure what they were talking about although she did really know what he was telling her and then she got out of his car and watched him drive away.Writing PromptYou have just read Sleeping by Katharine Weber in which a young girl is asked to babysit a child that she will never see.
