Lithium and magnesium bromide react to produce lithium bromide and magnesium metal

Answers

Answer: [tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]

Explanation:

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

A more reactive element is one which can easily lose or gain electrons as compared to the other element.

The balanced chemical equation is:

[tex]2Li+MgBr_2\rightarrow 2LiBr+Mg[/tex]

Here Lithium being more reactive than magnesium, it can easily displace magnesium from its salt solution and form lithium bromide and magneium in elemental form.

There are some climates in which there are no living things. true or false​

Answers

Answer:

True

Explanation:

There are some climates in which there are no living things. The average of the weather is the climate.

What is climate ?

Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years.

Every element of our life is impacted by the climate, including our food supplies, transportation systems, clothing choices, and vacation destinations. It significantly affects our future, our health, and our means of subsistence. Climate is the long-term trend of the weather in any given location.

As an illustration, you can anticipate snow in the Northeast in January or hot and muggy weather in the Southeast in July. Climate is this. Extreme values, such as record-breaking high temperatures or heavy rainfall, are also part of the climatic record.

Thus, there are some climates in which there are no living things.

what mass of NH3 (g) is produced when 2 x 10^23 molecules of N2 reacts

Answers

Answer:

m=8.58

Explanation:

[tex]n = \frac{m}{mr} [/tex]

N=n÷la

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

N[tex]_2[/tex] + 3H[tex]_2[/tex]  [tex]\rightarrow[/tex] 2NH[tex]_3[/tex]

moles of N[tex]_2[/tex]= given number of molecules/ 6.022×10²³

                  = 2 x 0²³/ 6.022×10²³

                  = 0.33 moles

moles of NH[tex]_3[/tex] produced= moles of N[tex]_2[/tex]×2

                                      =0.66moles

mass of NH[tex]_3[/tex]= moles of NH[tex]_3[/tex]×Molar mass of NH[tex]_3[/tex]

                    =  0.66 × 17.03

                    =11.23 g

Therefore, what mass of NH[tex]_3[/tex] (g) produced is 11.23 g.

How is the glucose level in the blood maintained? Which body system, organs, and hormones are used and what do they do?

Answers

Answer:

Explanation:

Insulin is an hormone used to regulate blood glucose, as it helps to maintain a balance. It allows for transport of glucose to organs such as liver.

The process of glucose regulation is a complex process. When food is eating glucose is absorbed into the bloodstream this happen from the gut and it raises the blood glucose level this causes insulin(hormone) to be released from the pancreas so glucose can move inside the cells and be used.

As glucose moves inside the cells, the glucose level inside the bloodstream returns to normal and insulin release slows down.

Glucose which is the main energy source used by cells is allowed to be taken up by muscles, liver and fat (adipose tissue) and use as a source of energy so they can function properly.
