Answer:
c. isotope number
Explanation:
Mass Number is the sum total of mass of protons and neutrons present in the nucleus of an atom. Generally they are being used in distinguishing isotopes. E.g Carbon - 12, Carbon - 13
Atomic Number is the number of protons. Every single element has it's unique atomic number and can be used in identification purpose. E.g Carbon - 6, Hydrogen - 1.
The correct option is option C. This is the symbol that is not necessary for the identification of a nuclide.
Answer:
1/45 or 0.0222 g/s
Explanation:
rate of reaction = quantity of reactant used/time taken
= (10-8)/90
= 1/45 or 0.0222 g/s

Answer:
<u>The pressure inside becomes : 202.646 KPa</u>
Explanation:
Given ,
- <em>The temperature inside the cylinder is constant</em>
- <em>The number of moles of the gas inside the cylinder will also be constant because it's a closed one.</em>
<em>Now according Boyle's law , </em>
- <em>The pressure of a gas of fixed mass is inversely proportional to its volume at a constant temperature.</em>
Thus ,
is the initial pressure 
is what we need to find
- initial volume
- final volume
∴
The pressure inside becomes : 202.646 KPa
Answer:
1. micro
2. centi
3. milli
4. kilo
Explanation:
Prefixes, in mathematical exponents, are defined as the alphabetical names associated with the mathematical factors. Some examples are as follows:
10⁶ = Mega
10⁹ = Giga
10⁻⁹ = Nano
10⁻¹² = Pico
So, in order to name the metric system prefixes associated with each of the given mathematical factor, we first convert the factor into exponent form and then write its prefix, as follows:
10⁻⁶ = <u>micro</u>
1/100 = 0.01 = 1 x 10⁻² = <u>centi</u>
0.001 = 1 x 10⁻³ = milli
1000 = 1 x 10³ = <u>kilo</u>
