Homeostasis:

It is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties.

In plant it is necessary to maintain homeostasis to function properly. Endocrine plays an important role in homeostasis as hormones regulate the activity of body cells and the release of hormones into the blood is controlled by a stimulus that either causes an increase or a decrease in the amount of hormone secreted.

What experimental evidence did Thomson have for each statement?
Minchanka [31]
<span>Thomson studied electric discharge in a vacuum and found that the deflection of rays was evidence of atoms containing much smaller particles. He calculated that these particles would have a large charge in relation to their mass. While he did not name electrons, he knew they existed.</span>

The heat of vaporization of 1-pentanol is 55.5 kJ/mol, and its entropy of vaporization is 148 J/K.mol. What is the approximate b
____ [38]

Answer:

Approximately 100 °C.

Explanation:

Hello,

In this case, since the entropy of vaporization is computed in terms of the heat of vaporization and the temperature as:

\Delta S_{vap}=\frac{\Delta H_{vap}}{T}

We can solve for the temperature as follows:

T=\frac{\Delta H_{vap}}{\Delta S_{vap}}

Thus, with the proper units, we obtain:

T=\frac{55500J/mol}{148J/(mol*K)} =375K\\\\T=102 \°C

Hence, answer is approximately 100 °C.

Best regards.

Elements in group 1 will (lose or gain) electrons to obtain a noble gas structure. How many electrons will the element gain or l
Whitepunk [10]
Answer is: elements in group 1 will lose electrons to obtain a noble gas structure. They will lose 1 electron.
For example ₃Li 1s²2s¹ will lose one electron from 2s oribtal to obtain helium structure ₂He 1s².
Or sodium ₁₁Na 1s²2s²2p⁶3s¹ will also lose one electron to obtain neon structure ₁₀Ne 1s²2s²2p⁶.

What is the mass of 3.25 mol of h2so4
Setler [38]

Answer/ explanation :

The find the mass,

We use this formula

Number of mole = mass/ molar mass

Since number of mole = 3.25mol

Number of mass be x

Molar mass of H2SO4

H - 1.00784 * 2= 2.01568

S - 32.065

O - 15.999 * 4 = 63.996

Note there are 2 moles of H and 4 moles of O and 1 mole of S

Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996

= 98.07668g/mol

Number of mole= 3.25mol

3.25 = x / 98.07668

x = 3.25 * 98.07668

= 318.749g

Therefore, the number of mass is 318.749g
