What happens if you put a cat in the microwave?
Wewaii [24]

She said that the exposure to the radiation in the microwave would have cooked the animal's internal organs. She said: 'It is a horrific case in the fact that the death of the cat would have been prolonged and it is unimaginable what it would have gone through taking some time to die.

The graph below shows how the pH of the soil in
kondor19780726 [428]

Answer:

Point B

Explanation:

From 0 - 7 on the pH scale, substances are said to be acidic. At 7, the substance is said to be neutral. From 7 - 14, substances are basic.

Lime is a basic substance. Therefore, when it is added to the soil, one should expect that the soil becomes more basic. On the graph, this should be represented by the line increasing in pH. As such, the point at which lime was added was most likely Point B.

A chemical company makes ammonia by reacting nitrogen with hydrogen. The company needs to make 70 batches of ammonia for a clien
RSB [31]

Answer:- No, the company would not be able to full fill the order.

Solution:- The balanced equation for the formation of ammonia by the reaction of hydrogen with nitrogen is:

3H_2+N_2\rightarrow 2NH_3

We have been given with 22000 grams of nitrogen and 1000 grams of hydrogen. Let's convert grams of each to moles:

moles of nitrogen = 22000g N_2(\frac{1mol}{28g})

moles of nitrogen = 785.71 mol

moles of hydrogen = 1000g H_2(\frac{1mol}{2g})

moles of hydrogen = 500 mol

From balanced equation 3 moles of hydrogen react with 1 mol of nitrogen. Let's calculate how many moles of nitrogen would react with 500 mol of hydrogen:

500mol H_2(\frac{1mol N_2}{3mol H_2})

= 166.67 mol N_2

166.67 moles of nitrogen are required and 785.71 moles of it are available. It means nitrogen is in excess and hydrogen is limiting. Product yield depends on limiting reactant. So, let's calculate the amount of ammonia formed from moles of hydrogen as:

500mol H_2(\frac{2mol NH_3}{3mol H_2})(\frac{17g NH_3}{1mol NH_3})

= 5666.67g of ammonia

let's convert the grams of ammonia to number of batches as:

5666.67g NH_3(\frac{1 batch}{175g NH_3})

= 32 batches

Company needs to make 70 batches of ammonia but from given amounts of hydrogen and nitrogen only 32 batches could be made. It means the company would not be able to full fill the order.

This alkene can be prepared via Wittig reaction. Draw structural formulas for the aldehyde and the Wittig reagent.
Bad White [126]

Answer:

aldehyde and wittig reagent

Explanation:

Alkenes are the organic compounds with at least one c=c. They are homologous series with the general molecular formula of CnH2n.

The symbol R in the uploaded file is an alkyl, which has general formula of CnH2n+1.

Wittig reagent contains Phosphine with phosphorus and an oxygen atom  the number (n) in the alkyl groups determines the number of carbon atoms in the resulting alkene.
