Answer 1

Answer:

1.) Eyewash station --> D

2.) Absorbent material --> G

3.) Fire extinguisher --> F

4.) Safety Shower --> E

5.) Biohazard container --> J

6.) Broken glass container --> I

7.) Safety goggles --> C

8.) Lab apron --> H

9.) asbestos gloves --> A

10.) Latex gloves --> B

Explanation:

In an equipped laboratory, alot of safety equipments are made available and kept in area that it could be easily accessed in the laboratory. Safety or protective equipments are those materials that helps protect a laboratory personnel while at work on the lab.

These equipments include:

--> Eyewash station: This is an equipment used in the laboratory during emergency to rinse chemical from the eye. Therefore option D is correct.

--> Absorbent material: They are used to contain small spills in the laboratory. Therefore option G is correct.

--> Fire extinguisher: This equipment is used to put out small fires. Therefore F is correct.

--> Safety Shower: This is used to rinse away chemical from clothes and on skin during emergency. Therefore option E is correct.

--> Biohazard container: This container is used to safely dispose bacteria culture, blood and other living tissues. Therefore option J is correct.

--> Broken glass container: This is used to dispose cracked, chipped or broken bottle in the laboratory. Therefore option I is correct.

--> Safety goggles: This helps to protect the eye from chemical and broken glasses. Therefore option C is correct.

--> Lab apron: This is worn by the laboratory personnel to help protect the skin from chemical and biohazards. Therefore option H is correct.

--> Asbestos gloves: these are heat resistant gloves used to protect the hands from heat. Therefore option A is correct.

--> Latex gloves: these are equally worn by the laboratory personnel to protect the hands from chemicals and biohazards

What's the mass in grams of 0.334 moles of sucrose (C12H22O11)?

Answers

Answer:

114.23g

Explanation:

Mass = xg

Mole = 0.334 mol

Molar mass of Sucrose

(C = 12, H = 1, O = 16)

C12H22O11

(12×12)+(1×22)+(16×11)

144 + 22 + 176

342g/mol

Mass = No of mole × Molar mass

Mass = 0.334 × 342

Mass = 114.228

Mass ≈ 114.23g

What is the mass of 5.55 moles of carbon monoxide

Answers

Answer:

[tex]\boxed {\boxed {\sf 155 \ g\ CO}}[/tex]

Explanation:

To convert from moles to mass, the molar mass must be used.

First, write the chemical formula for carbon monoxide. Since the carbon (C) comes first without a prefix, there is 1 carbon atom. The prefix mono- before oxide means 1, so there is also 1 oxygen (O) atom. The formula is CO.

Next, look up their molar masses on the Periodic Table.

C: 12.011 g/mol O: 15.999 g/mol

Since there is 1 atom of each, the molar masses can be added.

CO: 12.011 g/mol + 15.999 g/mol = 28.01 g/mol

Use this molar mass as a ratio.

[tex]\frac {28.01 \ g \ CO} {1 \ mol \ CO}[/tex]

Multiply by the given number of moles:5.55

[tex]5.55 \ mol \ CO *\frac {28.01 \ g \ CO} {1 \ mol \ CO}[/tex]

The moles of carbon monoxide cancel.

[tex]5.55 * \frac {28.01 \ g \ CO} {1 }[/tex]

Multiply.

[tex]155.4555 \ g \ CO[/tex]

The original measurement of moles has 3 significant figures, so our answer must have the same. For the number we calculated, it is the ones place. The 4 in the tenths place tells us to leave the 5.

[tex]155 \ g\ CO[/tex]

5.55 moles of carbon monoxide is about 155 grams.

What is the pH of this solution?

Answers

Answer:

pH = 11.216.

Explanation:

Hello there!

In this case, according to the ionization of ammonia in aqueous solution:

[tex]NH_3+H_2O\rightleftharpoons NH_4^++OH^-[/tex]

We can set up its equilibrium expression in terms of x as the reaction extent equal to the concentration of each product at equilibrium:

[tex]Kb=\frac{[NH_4^+][OH^-]}{[NH_3]} \\\\1.80x10^{-5}=\frac{x*x}{0.150-x}[/tex]

However, since Kb<<<1 we can neglect the x on bottom and easily compute it via:

[tex]1.80x10^{-5}=\frac{x*x}{0.150}\\\\x=\sqrt{1.80x10^{-5}*0.150}=1.643x10^{-3}M[/tex]

Which is also:

[tex][OH^-]=1.643x10^{-3}M[/tex]

Thereafter we can compute the pOH first:

[tex]pOH=-log(1.643x10^{-3}M)\\\\pOH=2.784[/tex]

Finally, the pH turns out:

[tex]pH=14-2.784\\\\pH=11.216[/tex]

i need help with this ASAP please i don’t understand this

Answers

Answer:

750 mmHg

Explanation:

From the question given above, the following data were obtained:

Partial pressure of CO₂ (Pₐ) = 250 mmHg

Partial pressure of N₂ (P₆) = 375 mmHg

Partial pressure of He (P꜀) = 125 mmHg

Pressure of the mixture (Pₜ) =?

The pressure of the mixture of the gases can be obtained as follow:

Pₜ = Pₐ + P₆ + P꜀

Pₜ = 250 + 375 + 125

Pₜ = 750 mmHg

Therefore, the pressure of the mixture of the gases is 750 mmHg

what is the volume, in liters, of 5.500 mol of C3H3 gas at STP

Answers

Answer:

123.2 Liters.

Explanation:

At STP (T = 273K & P = 1atm), one mol of any gas will occupy 22.4 liters.

With the above information in mind, we can calculate how many liters would 5.500 mol of gas occupy:

5.500 mol * 22.4 L / mol = 123.2 L

So 5.500 moles of C₃H₃ would have a volume of 123.2 liters at STP.

Convert 1.55 x 10^24 ATOMS OF CARBON TO MOLES OF CARBON

Answers

Answer:

2.57 moles of carbon

Explanation:

1 mole = 6.023x10^23 (this is called avogadro's number)

1/6.023x10^23

1.55x10^24 = 1.55x10^24/6.023x10^23 = 2.57 moles

this means, 1.55x10^24 atom contains 2.57 moles of carbon

Air in a closed cylinder is heated from 15°C to 36°C. If the initial pressure is 1000 torr, determine what is the final pressure? *

Answers

Answer:

1072 torr

Explanation:

To answer this problem we can use Gay-Lussac's law, which states:

P₁T₂=P₂T₁

Now we convert the given temperatures into K:

T₁ = 15°C ⇒ 15+273.16 = 288.16 KT₂ = 36°C ⇒ 36+273.16 = 309.16 K

We input the data:

1000 torr * 309.16 K = P₂ * 288.16 K

And solve for P₂:

P₂ = 1072 torr
