A stationary front (or quasi-stationary front) is a weather front or transition zone between two air masses, when neither air mass is advancing into the other at a speed exceeding 5 knots (about 6 miles per hour or about 9 kilometers per hour) at the ground surface. On weather maps, it is shown by a solid line of alternating blue spikes pointing to the warmer air mass and red domes pointing to the colder air mass. If your talking about a weather front Hope this helped.
I believe it is 56.3 hope this helps

Answer: Mass of gas is 0.001 pounds.
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of gas = ?
Density of gas = 
Volume of gas = 389 ml = 0.389 L (1L=1000ml)
Putting in the values we get:
(1g =0.002 lb)
Thus the mass of gas is 0.001 pounds.
Answer:
3
Explanation:
the half life of a radioactive isotope is the amount of time one half of the isotope takes to decay
after 5 minutes the mass will be 24
after 10 minutes the mass will be 12
after 15 minutes the mass will be 6
after 20 minutes the mass will be 3
<h2>Answer:</h2>
Unbalanced equation:
SiO2 + CaC2 → Si + CaO + CO2
Balanced equation:
5SiO2 + 2CaC2 → 5Si + 2CaO + 4CO2
<h3>Explanation:</h3>
- The chemical equation needs to be balanced so that it follows the law of conservation of mass.
- A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
