Answer:
A hydrocarbon and oxygen
Explanation:
hydrocarbon is being burned, and oxygen is necessary to burn things
Answer:
The pressure of N₂ gas in cylinder B when compressed at constant temperature increases due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container.
Explanation:
Gas helps to explain the behavior of gases when one or more of either temperature, volume or pressure is varying while the other variables are kept constant.
In the gas cylinder B, the temperature of the given mass of gas is kept constant, however, the volume is decreased by pushing the movable piston farther into the cylinder. According to the gas law by Robert Boyle, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature. This increase in pressure is due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container. As the cylinder becomes smaller, the gas molecules which were spread out further become more packed closely together, therefore, their frequency of collision increases building up pressure in the process.
After one half life, 188mg
46.9 mg of Ba-142
After 5 half lives
After 106 minutes
20 half lives , only 0.000358 mg remains
Hope this helps
Answer:
H2 + I2 —> 2HI
Explanation:
H2 + I2 —> HI
Now, let us balance the equation. This can be achieved by doing the following:
There are 2 atoms of H on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of HI as shown below:
H2 + I2 —> 2HI
Now the equation is balanced as there are equal numbers of atoms of the different elements present on both sides of the equation.
Answer:
they absorb water and nutrients through the roots
