Answer:
D
Explanation:
One of the properties of metals is their abilities to form a stable compounds by losing electron(s). Metals form positive ions (cations) when they lose electron(s).
C. 25 Miles
This is because you have 12.5 moles of water and using the ratio this is 2 (molar ratio). Therefore the molar ratio for HF is 4, so 12.5 x 2 = 25 moles

The momentum of the projectile is 6.8 * 10⁵ kgm/s
<h3>
Momentum and projectiles</h3>
Momentum of an object is the product of the mass of that object and its velocity.
where m is mass of object
v is velocity of object
A projectile is an object launched into space and allowed to fall freely under the force of gravity.
The momentum of a projectile is conserved in the horizontal direction since no net force acts on the projectile in the horizontal direction.
using the formula for momentum;
p = m*v
Assuming the mass of the projectile to be 800 kg
Velocity of the projectile = 850 m/s
p = 800 kg * 850 m/s
p = 6.8 * 10⁵ kgm/s
Therefore, the momentum of the projectile is 6.8 * 10⁵ kgm/s
