In 1500 kg of air there are 0.8 carbon dioxide. How many ppm does the carbon dioxide sample correspond to?
Explanation:
Given parameters:
Mass of air = 1500kg
Mass of carbon dioxide= 0.8g
Unknown:
PPM of carbon dioxide in the sample = ?
SOLUTION :
The parts per million ppm is used to express dilute concentration of solutes. It simple means out of a million.
To express the answer in ppm, first convert into uniform units:
1500kg to g = ?
1kg = 1000g
1500kg = (1500 x 1000)g = 1500000g
To express as part per million:
x 1000000
x 1000000 = 0.533ppm

Answer:
False.
Explanation:
Hello.
In this case since sodium is a soft brilliant metal and chlorine is a green gas at normal conditions, they have totally different properties. Thus, since sodium chloride is also known as the table salt which is present as white crystals we can infer that the compound does not have the same properties, therefore it is false.

Answer:
First and seventeenth group.
Explanation:
Hydrogen is a special case as it has only one electron in its outermost orbital.
The hydrogen can lose or can accept electron easily.
Thus it can form positive ion similar to alkali metals and negative ion similar to halogens.
Thus it can fall into two groups
a) I group [Alkali metals]
b) 17th Group [Halogens]
Explanation:
The study of interaction between the chemical substances is known as chemistry and the person who does this study is called a chemical scientist. Everything around us is made up of matter and the interaction between this matters for one or different substances.
Conduits lead electrical flow in all respects effectively as a result of their free electrons. Separators restrict electrical flow and make poor transmitters. Some basic channels are copper, aluminium, gold, and silver. Some regular encasing are glass, air, plastic, elastic, and wood.
The scientists would do biological studies of how the protein breakdown and combines with the muscles the engineers with then create a delivery system to get the protein to the muscle quicker and more effectively
