Answer:
22g of He
Explanation:
Volume of gas at STP is given as :
Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹
In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.
Number of moles =
Now, let us obtain the molar mass of the given atoms and elements:
For Ne; molar mass is the atomic mass = 20gmol⁻¹
He = 4gmol⁻¹
O₂ = (16 x2)gmol⁻¹ = 32gmol⁻¹
Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹
Number of moles of Ne = = 1.1mol
Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³
Number of moles of He = = 5.5mol
Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³
Number of moles of O₂ = = 0.688mol
Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol
Number of moles of Cl₂ = = 0.3099mol
Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³
Answer:
Yes, it accelerates
Explanation:
We have that:
The ball was stationary implies that its initial velocity, u = 0
It gained 5m/s means that its final velocity, v = 5m/s
Using first law of newton, we can determine whether it accelerates or not.
Substitute values for v and u
Make a the subject
<em>This implies that the ball accelerates over a period of time t</em>
<em></em>
Another way to tell if it accelerates or not is to consider the change in velocity.
When there is an increment in velocity of an object, the object accelerates.
In this case, the velocity increases from 0 to 5. Hence, we can conclude that it accelerates
