Answer: All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun. All living things grow. Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured. Chromists are a diverse group of plant-like organisms and range from very small to very large. They are found in almost all environments.
Explanation: I hope that helped yall!
Answer: -345.2 KJ
Explanation: As we know that ,dG=dH-TdS
T=25+273=298 K
dG= -356 x1000-298(-36)= -356000+10728
=-345272 j
= -345.2 KJ
Answer:
D. All of the above
Explanation:
E = MC² is a common equation in physics.
E is energy
M is mass
C is the speed of light
The law was stated by Albert Einstein.
- From this law, it was shown that energy is released when matter is destroyed.
- Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
- Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
- Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.
The molarity of the potassium acetate solution given the data is 1.584 M
<h3>What is molarity? </h3>
This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of CH₃COOK</h3>
- Mass of CH₃COOK = 19.4 g
- Molar mass of CH₃COOK = 98 g/mol
- Mole of CH₃COOK =?
Mole = mass / molar mass
Mole of CH₃COOK = 19.4 / 98
Mole of CH₃COOK = 0.198 mole
<h3>How to determine the molarity of CH₃COOK</h3>
- Mole of CH₃COOK = 0.198 mole
- Volume = 125 mL = 125 / 1000 = 0.125 L
- Molarity of CH₃COOK = ?
Molarity = mole / Volume
Molarity of CH₃COOK = 0.198 / 0.125
Molarity of CH₃COOK = 1.584 M
