Explain how to convert a mass of compound A to a mass of compound D in words using the following reaction:

2A + 4B = C + 3D

You don't have to just give me the answer but if you can help me understand id appreciate it greatly

Answers

Answer 1

Answer:

1. Convert the mass of A to moles dividing in molar mass

2. Convert the moles of A to moles of D (2mol A = 3mol D)

3. Convert the moles of D to mass multiplying by its molar mass

Explanation:

As you can see in the equation, 2moles of A produce 3 moles of D, the equation is:

2mol A = 3mol D

But in the problem you are having the mass of A and you need the mass of D. That means you require to convert the mass of A to moles. With the moles of A you can find the moles of D and, as last, you need to convert the moles of A to mass.

To convert mass to moles or vice versa you must use Molar Mass. That means, the answer is:

1. Convert the mass of A to moles dividing in molar mass2. Convert the moles of A to moles of D (2mol A = 3mol D)3. Convert the moles of D to mass multiplying by its molar mass

At the midpoint of a titration curve ________. At the midpoint of a titration curve ________. The concentration of a conjugate base is twice that of the concentration of a conjugate acid The pH equals the pKa The ability of the solution to buffer is at its least effective The concentration of a conjugate base is 1/2 that of the concentration of a conjugate acid

Answers

Answer:

The concentration of a conjugate base is twice that of the concentration of a conjugate acid

Explanation:

This is because at the midpoint, the number of moles of acid equals half the number of moles of base at the midpoint. This means that at the midpoint, half the analyte has been titrated.

Since the concentration of the conjugate acid is half that of the conjugate base at the midpoint, this implies that the concentration of the conjugate base is twice that of the conjugate acid.

Thus, at the midpoint of a titration curve the concentration of a conjugate base is twice that of the concentration of a conjugate acid

Ionic bonds involve the sharing of electrons D. Covalent bonds involve the transfer of one or more electrons from one atom to another

Answers

Answer:

hydrogen bonds are very weak and can only occur when polar covalent bonds are present

Explanation:

Hydrogen bonds are weak intermolecular interactions that occur when hydrogen is covalently bonded to a highly electronegative atom.

Owing to the difference in electro negativity between hydrogen and the highly electronegative atom, the bond is a polar covalent bond.

This hydrogen bond is a weak bond but accounts for properties such as high melting and boiling points of small molecules such as water and ammonia.

What has the most direct cause to the increase in the number and ferocity (strength) of storms hitting the Caribbean and the United States in recent years?

Answers

Answer:

High amount of humidity

Explanation:

This is especially common in the Caribbean, where hot temperatures very moisture and warm air provide near-ideal circumstances for hurricane formation, as assessed by the Saffir-Simpson classification and the Power Distribution Index.

"Hurricanes may originate everywhere in the Atlantic basin, from the subtropical central Atlantic to the Gulf coast. However, in order to make this all the way to the West Coast of the United States, the storms must pass over a lengthy length of sea water which is far too small to support hurricanes.

The storm strength is influenced by a lot of factors. Due to world warms and increase in the amount of humidity.

What is causing the increase in storm strength?

Studies has shown due too the warming of the world, hurricanes and other tropical cyclones are said to be more stronger.

This is due to the fact that warmer water gives more of the energy that boast storms. A rise in stronger hurricanes is due to warming never ending.

Answers

Answer:

A₃B₈ + 5C₂ –> 3AC₂ + 4B₂C

Explanation:

A₃B₈ + C₂ –> AC₂ + B₂C

The equation can be balance as illustrated below:

A₃B₈ + C₂ –> AC₂ + B₂C

There are 3 atoms of A on the left side and 1 atom on the right side. It can be balance by writing 3 before AC₂ as shown below:

A₃B₈ + C₂ –> 3AC₂ + B₂C

There are 8 atoms of B on the left side and 2 atoms on the right side. It can be balance by writing 4 before B₂C as shown below:

A₃B₈ + C₂ –> 3AC₂ + 4B₂C

There are 2 atoms of C on the left side and a total of 10 atoms on the right side. It can be balance by writing 5 before C₂ as shown below:

A₃B₈ + 5C₂ –> 3AC₂ + 4B₂C

Now, the equation is balanced.

Answers

Answer:

A book held high over a desk

Explanation:

Gravitational potential energy, or GPE, is like height energy. The higher up an object is placed, the more GPE it has. Gravitational potential energy is the potential of a certain mass relative to another due to gravity. In this case you have a book held high over a desk and therefore since it's higher up it's going to have more potential energy due to gravity, which is why it has gravitational potential energy. Therefore your answer is "a book held high over a desk".

Explanation:

Resistance for resistors in parallel

1/ R = 1/250 +1/250

=0.008

R = 1/ 0.008 = 125

Total resistance

R= 125+ 300

Radhika loves to eat sweets and chocolates. She asks her mother for the same before and after every meal. Explain if this is an example of bad eating habit or healthy eating habit?

Answers

Answer: Radhika loves to eat sweets and chocolates. She asks her mother for the same before and after every meal. This is an example of bad eating habit.

Explanation:

Both sweets and chocolates contain high amount of fat and sugar. When Radhika is eating the same before and after every meal then it means she is consuming it in excess.

When we eat too much of sweets and chocolates then its remains get deposited in between our tooth and when they remain over there for hours then more amount of bacteria is formed.

Due to this bacteria our tooth starts to decay.

Hence, it is advised even by the doctors to eat sweets and chocolates occasionally and not regularly.  

Thus, we can conclude that Radhika loves to eat sweets and chocolates. She asks her mother for the same before and after every meal. This is an example of bad eating habit.

The question is incomplete, the complete question is;

The half-life of strontium-90 is about 29 years. How many half-lives have elapsed when 6.25% of a strontium- 90 sample remains in the container?

Answer:

4 half lives

Explanation:

From;

N/No = (1/2)^t/t1/2

N= amount of strontium-90 present at time t

No= amount of strontium-90 originally present

t= time taken

t1/2 = half life of strontium-90

But N= 0.0625No

Hence;

0.0625No/No = (1/2)^t/29

0.0625 = (1/2)^t/29

(1/2)^4 = (1/2)^t/29

4 = t/29

t = 4 × 29

t= 116 years

Hence four half lives have elapsed
