Camphor is reduced to isoborneol by sodium borohydride in ethanol. The instructions for safe disposal of the chemical waste gene

rated by this reaction state that the lids should not be screwed back onto the waste containers. Why should the lids not be put back on the waste containers?A) The reaction waste is still generating hydrogen gas that would get trapped in the container.B) Allowing the volatile waste to evaporate will lower the cost of chemical waste removal.C) Leaving the lid off allows the layers within the container to separate from one another.D) The tag on the container that lists its contents cannot be read properly when the lid is on.

Answer:

The reaction waste is still generating hydrogen gas that would get trapped in the container.

Explanation: The chemical waste are dangerous and should be handled with care. The reactions don't stop immediately the products is formed putting the lid gives an enabling environment for chemical reactions to proceed.

What is the compound MnCl2 called?
givi [52]

Answer is Manganese(ii) chloride

To answer this, you need to know the charges for both Mn and Cl

Mn is in the transition metal category and is unique with having 3 levels of charges

manganese - MN

Manganese(ii) - Mn^2+

Manganese(iii) - Mn^3+


Cl is a nonmetal with the standard charge of Cl^-1

Since you have two charges that don't cancel out, they get switched.

So Cl would receive a positive 2. Because it was a positive 2, we can assume that it starts with Manganese(ii). Then we add chloride to the end of it as it ends with Cl.

A textbook measures 250 mm long, 225 mm wide and 50 mm thick. What is the volume of this book in mm3? What is the volume of this
Dvinal [7]

Answer:

2.81 × 10⁶ mm³

2.81 × 10⁻³ m³

Explanation:

Step 1: Given data

Length (l): 250 mm

Width (w): 225 mm

Thickness (t): 50 mm

Step 2: Calculate the volume of the textbook

The book is a cuboid so we can find its volume (V) using the following expression.

V = l × w × t = 250 mm × 225 mm × 50 mm = 2.81 × 10⁶ mm³

Step 3: Convert the volume to cubic meters

We will use the relationship 1 m³ = 10⁹ mm³.

2.81 × 10⁶ mm³ × 1 m³ / 10⁹ mm³ = 2.81 × 10⁻³ m³

Calculate the mass defect for the formation of phosphorus-31. The mass of a phosphorus-31 nucleus is 30.973765 amu. The masses o
Nata [24]

<u>Answer:</u> The mass defect for the formation of phosphorus-31 is 0.27399

<u>Explanation:</u>

Mass defect is defined as the difference in the mass of an isotope and its mass number.

The equation used to calculate mass defect follows:

\Delta m=[(n_p\times m_p)+(n_n\times m_n)]-M

where,

n_p = number of protons

m_p = mass of one proton

n_n = number of neutrons

m_n = mass of one neutron

M = mass number of element

We are given:

An isotope of phosphorus which is _{15}^{31}\textrm{P}

Number of protons = atomic number = 15

Number of neutrons = Mass number - atomic number = 31 - 15 = 16

Mass of proton = 1.00728 amu

Mass of neutron = 1.00866 amu

Mass number of phosphorus = 30.973765 amu

Putting values in above equation, we get:

\Delta m=[(15\times 1.00728)+(16\times 1.00866)]-30.973765\\\\\Delta m=0.27399

Hence, the mass defect for the formation of phosphorus-31 is 0.27399
