Answer: 2,3 * 4 = 9,2
Explanation:
If 1 mole CH4 has 4 H atoms 2,3 moles of CH4 will have 9,2 H atoms.
Kilograms and grams. They're both commonly used to measure mass.
Surely, If cells did not work together in an organism, there won't be formation of new cells and life process would stop
<h3>Living organisms </h3>
Living organisms; be it plants or animals are any organic or living system composed of cells and function as an individual entity.
- All living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.
- Animals and plants also posess systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.
- Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals
So therefore, surely, If cells did not work together in an organism, there won't be formation of new cells and life process would stop

The percent error between 20 and 20.5 is 2.5%
Explanation:
Percent Error = | (20.5 − 20) / 20 | × 100 = | (0.5) / 20 | × 100 = | 0.025 | × 100 = 2.5% (three decimal places)Percent Error = 2.5%
<u>We are given:</u><u>_______________________________________________</u>
Volume of Gas (V) = 2.5L
Pressure (P) = 1.2 atm
Temperature (T) = 25°C OR 25+273 = 298 K
Universal Gravitational Constant (R) = 0.0821
<u>Solving for number of moles:</u><u>___________________________________</u>
From the Ideal Gas Equation,
PV = nRT
(1.2)(2.5) = n(0.0821)(298) [plugging the given values]
n = [(1.2)(2.5)] / [0.0821*298]
n = 300 / [298*8.21]
n = 0.12 moles
Hence, there are 0.12 moles of Oxygen in 2.5L of 1.2 atm gas when the temperature is 25°C
