lubasha [3.4K]3 years ago
5 0

Answer: Yes, they have.

Explanation: The frequency, severity, and length of heat waves are increasing. Heat and humidity already kill an average of 1,300 people in the U.S. each year. Deadly heat waves of at least 20 days affect 30% of the earth's population. That will increase to 75% by 2100 if global warming isn't stopped.

Atrial natriuretic peptide is a hormone that controls blood pressure in part by increasing the urinary excretion of sodium. True
mariarad [96]

Answer:

The answer is "true"

Explanation:

ANP, or ANF, is a human peptide hormone, that controls your blood pressure, a cardiac atrium secretion hormone. It response primarily to the volume and stress expansion of the auricles and ventricles.

  • ANP's main function decreases the amount of increased extracellular fluid by increasing renal excretion.
  • This hormone is primarily developed by cardiovascular myocytes and, emanates from the wall tension locally, that's why the given statement is true.

SO2________________.
Mashcka [7]

Answer:

a. Dipole-dipole bonding

Explanation:

SO2 has dipole-dipole bonding. This is because of the difference in the electronegativities  of Sulphur and oxygen. Moreover, the lone pair of electrons on S gives it bent shape with a net dipole  unlike CO2 which has a linear shape.( This why CO2 does not have any dipole moment).

So, the correct answer is a.

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters
Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

P.V=n.R.T  

Where:  

P=2 atm is the pressure of the gas  

V is the volume of the gas  

n=1.5 mole the number of moles of gas  

R=0.0821\frac{L.atm}{mol.K} is the gas constant  

T=35\°C+273.15=308.15 K is the absolute temperature of the gas in Kelvin

Finding V:

V=\frac{nRT}{P}

V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}

V=18.97 L

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
