Answer:
si. en los atomos los protones y los electrones llevan cargas electricas
A solid will always hold its shape as long as there are no item/forces acting on it.
Liquids, plasma, and gases will never hold a shape on there own, mostly all liquids only hold the shape there given. Gases never really have a shape.And plasma is a form of energy, so its more like the gas, it has to be given a shape/container.
Answer :B
Hope this helps
Answer: Molar mass of CO2 is 44 gram/mol. So,the mass of 1 mole or 6.02*10^23 molecules of CO2 is 44 grams
Explanation:
Answer:
The mass of a solute divided by the mass of a solution times 100
Explanation:
The concentration of a solution refers to how much of a solute is dissolved in an amount of solvent. To express this concentration exist different methods, the mass percent concentration is one of them and is <em>defined as the mass of a solute divided by the mass of a solution times 100:</em>
<em>%m/m= (mass of a solute/mass of solution)x100</em>
<em>Where the mass of the solution is the sum of the mass of solute and mass of solvent.</em>
%m/m is commonly used when you can measure the masses of both solute and solution.
