Answer:
calcium to give calcium oxide to give calcium trioxocabonate (limestone) to give carbondioxide
Answer:
6.8g of solute are needed
Explanation:
Percent by mass, (w/w%) is defined as the mass of solute in 100g of solution. A solution that is 3.4% contains 3.4g of solute in 100g of solution. That means to make 200g of solution are required:
200g solution * (3.4g solute / 100g solution) = 6.8g of solute are needed
Answer:
BeCl2 + 2AgNO3 ---> Be(NO3)2 + 2AgCl
The pressure exerted when both gases are put together in a single 1 liter container is 5 atm.
<h3>What is pressure?</h3>
Pressure is the force exerted by any object on another object.
Given that, a and b separate 1 liter containers and exert pressure of 2 atm and 3 atm respectively.
When both gases a and b exert together, the pressure then
2 atm + 3 atm = 5 atm.
Thus, the pressure exerted when both gases are put together in a single 1 liter container is 5 atm.
