175 cm³ instead of 175 cm.
Answer:
297.5 cm³
Explanation:
From the question;
Initial volume; V1 = 175 cm³
Initial temperature; T1 = 25°C
Final temperature; T2 = 42.5°C
From Charles law we can find the volume V2 from the equation;
V1/T1 = V2/T2
Making V2 the subject gives;
V2 = V1 × T2/T1
V2 = (175 × 42.5)/25
V2 = 297.5 cm³
Answer:The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
Explanation:
Answer:
If the volume of a container is decreased, the temperature decreases, which means that the volume of a gas is directly proportional to its temperature
Answer:
The electrons where in motion
Answer:
5.00 grams of salt contain more particles than 5.0 grams of sugar
Explanation:
Salt = NaCl
Molar mass = 58.45 g/mol
Sugar = C₁₂H₂₂O₁₁
Molar mass = 342.3 g/mol
Sugar's molar mass is higher than salt.
So 1 mol of sugar weighs more than 1 mol of salt
But 5 grams of salt occupies more mole than 5 grams of sugar
5 grams of salt = 5g / 58.45 g/m = 0.085 moles
5 grams of sugar = 5g/ 342.3 g/m = 0.014 moles
In conclusion, we have more moles of salt in 5 grams; therefore there are more particles than in 5 g of sugar.
