kvasek [131]

Answer:

bines relative humidity and temperature in a comfort index

Explanation:

The Heat Index temperature measures how hot it feels when humidity is factored with the air temperature.

It is important for the human body's comfort.

The human body feels warmer in humid conditions it begins to perspire or sweat to cool itself off when the body gets too hot.

The concept of the heat index was developed by George Winterling  in 1978.

The heat index temperature makes assumptions regarding the human body mass and height, clothing, amount of physical activity etc.

The heat index temperature <u>bines relative humidity and temperature in a comfort index.</u>

Does the reaction of a main-group metal oxide in water produce an acidic solution or a basic solution? Write a balanced equation
Fynjy0 [20]

<u>Answer:</u> The main group metal produce a basic solution in water and the reaction is MO+H_2O\rightarrow M(OH)_2

<u>Explanation:</u>

Main group elements are the elements that are present in s-block and p-block.

The metals that are the main group elements are located in Group IA, Group II A and Group III A.

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

  • Acidic oxides are formed by the non-metals.
  • Basic oxides are formed by the metals.

When a metal oxide is reacted with water, it leads to the formation of a base.

The general formula of the oxide formed by Group II-A metals is 'MO'

The chemical equation for the reaction of metal oxide of Group II-A and water follows:

MO+H_2O\rightarrow M(OH)_2

Hence, the main group metal produce a basic solution in water and the reaction is MO+H_2O\rightarrow M(OH)_2

lys-0071 [83]

Answer:

The complete aerobic oxidation of glucose is coupled to the synthesis of as many as 36 molecules of ATP

Explanation:

Glycolysis, the initial stage of glucose metabolism, takes place in the cytosol and does not involve molecular O2. It produces a small amount of ATP and the three-carbon compound pyruvate. In aerobic cells, pyruvate formed in glycolysis is transported into the mitochondria, where it is oxidized by O2 to CO2. Via chemiosmotic coupling, the oxidation of pyruvate in the mitochondria generates the bulk of the ATP produced during the conversion of glucose to CO2. The biochemical pathways that oxidize glucose and fatty acids to CO2 and H2O.

In a certain city, electricity costs $0.13 per kW·h. What is the annual cost for electricity to power a lamp-post for 5.50 hours
My name is Ann [436]
We know power=work done/time taken
power*time= work
100watt=0.1kw
total work in a day= power* time
0.1*5.5=0.55kwh
for 1 year total.energy is 0.55*365=200.75kwh
cost is 200.75*0.13=26.0975dollars
for 25 watt it is 0.025*5.5*365*0.13=6.524375 dollars
