Ice is the solid phase of water, so it is not silicate.
In order to determine if the ion is positively charged or negatively charged
Answer:
Time = 3.27s
Explanation:
Time = Distance / Speed
Time = 42.2 / 12.9 = 3.2713
When you multiply the number of significant figures in the result is the same as the number with the least significant figures.
In this case 42.2 has 3 significant figures and 12.9 also has 3 significant figures, therefore the answer must have 3 significant figures too.
Time = 3.27 s
Answer:
the carbon monoxide will release blue fumes
Dissolving 0.729 mol NaCl in 2530 mL of water yields a solution with 2.88M concentration.
Explanation:
The moles of NaCl given will be dissolved and volume will be made with given data will give molarity.
The units for molarity are moles/litre, so the volume given in ml will be converted to litres by dividing it with 1000.
data given:
number of moles of NaCl = 0.729 moles
volume of the solution = 2530 ml or 2.53 litre
To calculate the concentration of the solution the formula used is:
molarity = 
= 0.288 M
The concentration or molarity of the solution OF NaCl is 2.88M
