Answer:
When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the
blood becoming less than 7.35. The body maintains the balance mainly by using bicarbonate ions in the
blood. As the body responds to neutralize this condition, an electrolyte imbalance – an increase of plasma
chloride, potassium, calcium and sodium, can occur.

Determine the freezing point and boiling point of a solution that has 68.4 g of sucrose
(C12H22011) dissolved in 100.g of water?
Answer:
Freezing T° of solution = - 3.72°C
Boiling T° of solution = 101.02°C
Explanation:
To solve this we apply colligative properties. Firstly, freezing point depression:
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Cryoscopic constant, for water is 1.86 °C/m
m = molality (moles of solute in 1kg of solvent)
i = Ions dissolved in solution
Our solute is sucrose, an organic compound so no ions are defined. i = 1.
Let's determine the moles: 68.4 g . 1mol/ 342g = 0.2 moles
molality = 0.2 mol / 0.1kg of water = 2 m
We replace data: ΔT = 1.86°C/m . 2m . 1
Freezing T° of solution = - 3.72°C
Now, we apply elevation of boiling point: ΔT = Kb . m . i
ΔT = Boiling T° of solution - Boiling T° of pure solvent
Kf = Ebulloscopic constant, for water is 0.512 °C/m
We replace:
Boiling T° of solution - Boiling T° of pure solvent = 0.512 °C/m . 2 . 1
Boiling T° of solution = 0.512 °C/m . 2 . 1 + 100°C → 101.02°C
Which best describes the velocity of a person on a merry-go-round? * 1 point zero constant increasing continuously changing
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

Answer:
Earnings based on how much they sell
Explanation:
A sales presentation can be defined as series of talk given by a salesperson with the attempt to persuade someone or a potential customer to buy a particular product, by giving information it. Some salespersons resort to the use of dramatics so as to initiate and close the sale of a particular product by engaging in series of theatrical actions.
In sales and marketing, the term closing with respect to a sales can be defined as the process of making a business sale successful such as through the exchange of money for a particular product or goods.
For a salesperson to be able to close a sales, he or she require abilities such as courage, negotiation skills, listening ears and interpersonal skills to do so or achieve a successful sales. After a successful sales, they're entitled to a percentage of the amount made from selling a particular product or closing a deal based on what is stated in the contract. These amount of money earned with respect to each sales is generally referred to as commissions.
Commission can be defined as an amount of money earned based on how much a salesperson sell.

which anion forms a neutral compound when combined with a group 2 monatomic cation in a 1:1 ratio?
A) Fluoride.
B)Nitrate.
C)Phosphide.
D)Sulfide.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the correct option is option D that is sulfide.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Ionic compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.
The valency of group 2 element is +2 so, the anion that is required to form a compound with these element in a 1:1 ratio must have valency of -2. the only anion in th given option which have -2 valency is sulfide.

The oil that Syncrude mines from the Athabasca Tar Sands contains large amounts
of undesirable sulfur. To remove most of the sulfur, Syncrude uses a chemical
process known as the Claus process, which results in a low-sulfur "sweet crude oil.
Two steps involved in Claus process are shown below.
Step! H2S(g) + 02(9) - S02(g) + H2O(g) AH = - 518 kJ
Step || SO2(g) + 2 H2S(g) - 3 S(I) + 2 H2O(g) AH = -93 kJ

Explanation:
12.7 grams of magnesium chloride is dissolved into water in a flask and set aside for an experiment. The scientist forgets about the solution and the sunlight evaporates it. She needs at least 11 grams of magnesium chloride to continue the experiment. Will she be able to recover enough magnesium chloride from the original flask to continue the experiment
Answer:
Yes, she will be able to recover enough magnesium chloride from the original flask to continue the experiment
Explanation:
The solution prepared by the scientist contains 12.7g of magnesium chloride. The sunlight will evaporate only the water present. When the volume decreases, the magnesium chloride precipitates. When all water evaporates, all the solute, magnesium chloride precipitates totally.
That means she will recover the 12.7g of magnesium chloride.
Answer: Yes, she will be able to recover 12.7g in the flask
