Answer:
139.11 grams
Explanation:
The molarity (M) is equal to m (moles) /L (liters).
Notice how it is in mL so converting it would be 0.75 L (750*10-3)
Now plug in the information
1.75=m/0.75
m=1.3125
Now m is in moles so convert to grams to get the mass
1.3125 mol Na2CO3 * 105.9888 g Na2CO3 = 139.1103
Answer:
The pressure decrease with the passage of time due to again dissolution of carbon-dioxide gas in the liquid solution.
Explanation:
In soft drinks, the carbon-dioxide gas is added in the drinks with high pressure because carbon-dioxide is a gas which is insoluble in soft drink at room temperature but soluble in the drinks at high pressure so when the pressure is removed from the soft drink, the carbon-dioxide gas releases in the air with the passage of time. But in close bottle , there is no place of escape so it again dissolve in the solution.
Cross-section of a metal wire wrapped in plastic insulation the metal wire is an element.
<h3>What is an element?</h3>
An element is a substance or material that cannot be affected by an external substance or cannot be broken down by any reaction.
Metal wire is serving as an element, it should not be easily broken or penetrated as an insulator.
Therefore, Cross-section of a metal wire wrapped in plastic insulation the metal wire is an element.
