The absolute value of any number is positive
Answer:
hope this helps.answer is in the picture
The balanced chemical reaction is written as :
Na2CO3<span> + 2HCl === 2NaCl + H2O + CO2
</span>
We are given the amount of NaCl to be produced from the reaction. This will be the starting point for the calculations. We do as follows:
120 g NaCl ( 1 mol / 58.44 g) ( 1 mol Na2CO3 / 2 mol NaCl)( 105.99 g / 1 mol ) = 1108.82 g Na2CO3 needed
Answer:40.0g
Explanation:solution holds .8 moles per liter
Answer:
The correct option is: (C) It included negatively charged particles.
Explanation:
Sir Joseph John Thomson proposed an atomic model, known as the plum pudding model in 1904.
In this model, he<u> compared an atom to a plum pudding</u> and suggested that the <u>negatively charged electrons are the plums that are embedded in a uniform positively charged spherical pudding.</u>
Therefore, according to the plum pudding model, <u>an atom has no net electric charge</u> and <u>contains negatively charged electrons.</u>
