what is the formula for tin(III) sulfate​

Answer:

a. Volatile.

b. Air foil.

c. Sash.

d. Work surface.

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

I. Solid.

II. Liquid.

III. Gas.

Matching the terms with their respective definition, we have;

a. Volatile: A characteristic that describes substances that evaporate readily, producing large amounts of vapors.

b. Air foil: the front vent of a fume hood, which helps maintain proper air circulation.

c. Sash: the glass panel in front of the fume hood that shields the user from fumes and other hazards.

d. Work surface: the horizontal, flat area of a fume hood upon which experiments are carried out.

Answer:

A front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.

Answer:

The answer is "12.06"

Explanation:

Given:

[tex]M(HBrO) = 0.3\ M\\\\V(HBrO) = 20 \ mL\\\\M(KOH) = 0.15 \ M\\\\V(KOH) = 64 \ mL[/tex]

[tex]\to mol(HBrO) = M(HBrO) \times V(HBrO) = 0.3 M \times 20 mL = 6 \ mmol\\\\\to mol(KOH) = M(KOH) \times V(KOH)= 0.15 M \times 64 mL = 9.6 mmol[/tex]

  6 mmol of both will react

excess KOH remaining[tex]= 3.15 \ mmol[/tex]

Volume[tex]= 20 + 64 = 84 \ mL[/tex]

[tex][OH^{-}] = \frac{ 9.6 \ mmol}{84\ mL} = 0.01142\ M[/tex]

use:

[tex]pOH = -\log [OH^-][/tex]

        [tex]= -\log (1.142\times 10^{-2})\\\\= 1.94[/tex]

use:

[tex]PH = 14 - pOH[/tex]

       [tex]= 14 - 1.94\\\\= 12.06[/tex]

The pH of the resulting  solution is  12.63.

The equation of the reaction is;

HBrO(aq) + KOH(aq) ------> KOBr(aq) + H2O(l)

Number of moles of KOH= 64/1000 × 0.150 M = 0.0096 moles

Number of moles of HBrO = 20/1000 × 0.300 M = 0.0060 moles

Number of moles of excess base = 0.0096 moles -  0.0060 moles = 0.0036 moles

Total volume of solution = 64.0 mL +  20.0 mL = 84 mL = 0.084 L

Molarity of excess base =  0.0036 moles/0.084 L = 0.043 M

pOH = -log[OH-]

pOH = -log[ 0.043 M]

pOH = 1.37

pH + pOH = 14

pH = 14 -pOH

pH = 14 - 1.37

pH = 12.63

Answer:

C. Biodiesel made from plant oil.

Explanation:

The  type of vegetable oil used in production greatly affects the performance of biodiesel in the winter. The less saturated the fat, the better the performance in winter time. Canola oil works very well for low temperature biodiesel, and palm oil is among the worst for cold weather performance.

Answer:

C) 0.457

Explanation:

The ratio between O2 and H2O is 1:2 according to the balanced equation. You can find how many moles is O2 by : 5.12/22.4 = 0.22857 ( 1 mole = 22.4 litters)

Moles of H2O will be 0.22857 * 2 = 0.457142.

Therefore answer C)

Answer:

Ksp of PbSO4 is 2.5 *10^-8

Explanation:

Given -

Solubility of PbSO4 = 0.048g/Liter

[Pb+2] * [SO42-] = mass/molecular weight of PbSO4

[Pb+2] * [SO42-] =  0.048g/Liter/303.3g/mol = 0.000158 M

Concentration of PbSO4 = moles/volume = 0.000158 M/1L = 0.000158 M

Ksp = [Pb+2] * [SO42-]

ksp = 0.000158 * 0.000158 = 2.5 *10^-8

Answer:

-198 kJ

Explanation:

Hello there!

In this case, as the reaction is not given but we can see that HBr is formed, we can infer that reaction is:

[tex]H_2+Br_2\rightarrow 2HBr[/tex]

Whereas the -72 kJ per moles of HBr are:

[tex]\frac{-72kJ}{2molHBr}[/tex]

Thus, by multiplying by the formed 5.5 moles of HBr, the total energy release is:

[tex]\frac{-72kJ}{2molHBr} *5.5molHBr\\\\=-198kJ[/tex]

Answer:

The equilibrium constant is 2.08x10⁵

Explanation:

Based on the reaction:

3NO ⇄ N₂O + NO₂

The equilibrium constant, k, is defined as:

k = [NO₂] [N₂O] / [NO]³

Where the [] is the molarity in equilibrium of each specie.

Computing te values of the problem:

k = [1.5x10⁻¹M] [2.4x10⁻³M] / [1.2x10⁻³M]³

k = 2.08x10⁵

Explanation:

The conductivity of water refers to how much it conducts electricity. The electrical conductivity of water increases as more ions are dissolved in it.

Hence, increase in concentration of dissolved ions improves the electrical conductivity of water.

Therefore, when a base (which is an ionic substance) is dissolved in water, the concentration of ions present increases and the conductivity of the solution increases accordingly since ions are charge carriers in solution.

The addition of a base to the sample results in an increase in the conductivity of the sample.

Conductivity can be defined as the transfer of charge by the sample. The sample has consisted of the ions that mediate the transfer of charge.

The sample with a high number of ions has consisted of high conductivity and vice versa. The dissolution of acid or base to the solution results in an increase in the number of ions in the solution, and thereby there has been an increase in the charge transfer.

Thus, with the increase in the charge transfer, there has been an increase in the conductivity of the sample.

Answer: 2755.2 g of [tex]Fe[/tex] will be produced from 24.6 mol of haematite.

Explanation:

The balanced chemical equation is:

[tex]Fe_2O_3+3CO\rightarrow 2Fe+3CO_2[/tex]  

According to stoichiometry :

1 mole of [tex]Fe_2O_3[/tex] produce = 2 moles of [tex]Fe[/tex]

Thus 24.6 moles of [tex]Fe_2O_3[/tex] will produce=[tex]\frac{2}{1}\times 24.6=49.2moles[/tex]  of [tex]Fe[/tex]  

Mass of [tex]Fe=moles\times {\text {Molar mass}}=49.2moles\times 56g/mol=2755.2g[/tex]

Answer:

Explanation:

The correct option would be that the average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

According to the kinetic theory of matter, the temperate of a substance is a measure of the average kinetic energy of the molecules of substance. In other words, the higher the temperature of a substance, the higher the average kinetic energy of the molecules of the substance.

In the illustration, the gas in container B showed a higher temperature than that of container A as indicated on the thermometer, it thus means that the average kinetic energy of the molecules of gas B is higher than those of gas A.

Answer:

The pressure is equal to 4.87 torr and 0.649 kPa.

Explanation:

The atmospheric pressure was determined to be on the average about 6.50 millibars.

As 1 bar = 0.987 atm

6.5 mbar = 0.0065 bar

So,

0.0065 bar = (0.0065×0.987 ) atm

= 0.0064155  atm

Since, 1 atm = 760 torr

So, 0.0064155  atm = 4.87 torr

Since, 1 torr = 133.322 Pa

4.87 torr = 649.27 pa

or

4.87 torr = 0.649 kPa

Hence, the required pressure is equal to 4.87 torr and 0.649 kPa.
