Answer:
1 mole of atoms contains 6.022×1023 atoms. Thus, 0.2 mole of sodium element has 12.044×1022 atoms in it.
Explanation:
Answer:
distance decreases and force increases
Explanation:
- Simple machine means less power
- Hence it will require more force.
- Hence distance will decrease with respect to force and force will decrease
Answer:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

<span>Ideal gas is used to explain the behavior of a gas sample. In ideal gas law, the equation is PV=nRT where R has a constant of 0.0821L.atm/mol.K. It can explain the behaviior of a gas in three types: mole, mass and density. The ideal gas often observed in a high temperature with low pressure as to potential energy becomes less significant compared to the kinetic energy.</span>
