BLOOD HELPS YOUR BODY TO STAY AT TEMPERATURE OF ABOUT _____C. *

Chemistry
1 answer:
Paladinen [302]3 years ago
7 0

Answer:The average normal body temperature is most often said to be 98.6° F (37° C). ... One small study even suggested that in healthy older patients, body temperature ranged from 94° F to 99.6° F, with an average of 97.7° F. Several factors can lead to a lower body temperature in older people

Explanation:so the answer would be 37

Solution of the Schrödinger wave equation for the hydrogen atom results in a set of functions (orbitals) that describe the behav
kvv77 [185]

Answer :

'n' specifies  → (B) The energy and average distance from the nucleus.

'l' specifies   → (C) The subshell orbital shape.

'ml' specifies → (A) The orbital orientation.

Explanation :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from (-l\text{ to }+l). When l = 2, the value of

Spin Quantum number : It describes the direction of electron spin. This is represented as m_s. The value of this is +\frac{1}{2} for upward spin and -\frac{1}{2} for downward spin.

As per question we conclude that,

'n' specifies  → The energy and average distance from the nucleus.

'l' specifies   → The subshell orbital shape.

'ml' specifies → The orbital orientation.

Ca(s) + O₂(g) + S(s) → CaSO4(s)
san4es73 [151]

The mass of Calcium required to complete this reaction is 4.008 g.

  • Law of conservation of mass states that In a closed system, mass cannot be produced or destroyed, but it can be changed from one form to another.
  • The mass of the chemical constituents before a chemical reaction is equal to the mass of the constituents after the reaction.
  • In several disciplines, including chemistry, mechanics, and fluid dynamics, the idea of mass conservation is widely applied.

In the given reaction mass of product after completion of reaction is 13.614 g that means total mass of constituents before reaction should also be 13.614.

So,

mass of Ca + mass of O₂ + mass of S = mass of CaSO4

Ca + 6.400 g + 3.206 g = 13.614 g

mass of Ca = 13.614 - 9.606 = 4.008 g

Therefore, by law of conservation of mass 4.008 g of Ca is required for the completion of the reaction.

Describe how a positive result for the Baeyer Test will look. What is being oxidized? What is being reduced?
Ksivusya [100]

Answer:

This reaction is sometimes referred to as the Baeyer test. Because potassium permanganate, which is purple, is reduced to manganese dioxide, which is a brown precipitate, any water‐soluble compound that produces this color change when added to cold potassium permanganate must possess double or triple bonds.

A sample of 0.300 mol of a metal m reacts completely with excess fluorine to form 23.4 g of mf2. what element is represented by
Phoenix [80]

Molecular weight of m is 40g. Hence, name of element m is Calcium. which is represented by the symbol Ca.

Given,

Moles of metal M = 0.300 moles

 weight of mF₂ formed =23.4g

we have to find the name of element m...

Now,

 m + F₂ → mF₂

1 mole of m reacts with 1 mole of F₂ (or 2 molecule of flourine) to form 1 mole of mF₂

Hence,

 0.300 moles of m reacts with 0.300 moles of F₂ to form 0.300 moles of mF₂.

 

Hence,

 23.4 g = 0.300 moles of mf2

0.300 × 38g + 0.300 × m = 23.4 g

Hence

 m = 40 g

So, molecular weight of m is 40g. Hence, name of element m is Calcium. which is represented by the symbol Ca.

 Thus, from the above conclusion we can say that, name of element m is Calcium. which is represented by the symbol Ca.
