Answer:
b) 3x10³m³
Explanation:
The volume of each astronaut breathing in m³ is:
500cm³ * (1x10⁻⁶m³ / 1cm³) = 5x10⁻⁴m³
In 1 minute, the volume is:
5x10⁻⁴m³ * 15 = 7.5x10⁻³m³
In 1 hour:
7.5x10⁻³m³ /min * (60min / 1 hour) = 0.45m³/h
In 1 day:
0.45m³/h * (24h / 1 day) = 10.8m³/day
In 1 year:
10.8m³/day * (365 days / 1 year) = 3942m³ = 3.9x10³m³
That is approximately:
<h3>b) 3x10³m³</h3>
The mass of the balloon decreases as the release of hydrogen gas.
<h3>Mass of hydrogen and percent change</h3>
If the balloon had expanded more then the mass of hydrogen gas will increase inside the balloon but the mass of the balloon decreasing because the hydrogen gas escape from the system means from the balloon.
There is less percent change in the mass of the balloon while on the other hand, the concentration of hydrogen gas increases inside the balloon which leads to expansion of balloon so we can conclude that the mass of the balloon decreases as the release of hydrogen gas.

It depends on what is is mixed on
Answer 1 : The balanced complete ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Answer 2 : The balanced net ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Answer 3 : The balanced net ionic equation will be,
By removing the spectator ion in this equation, we get the balanced ionic equation.
Balanced equations : Balanced equations are the equations in which the number of individual elements present on the reactant side must be equal to the number of individual elements present on the product side.
Spectator ions : It is defined as the ions which do not participate in the chemical reaction. These ions exists in the same form on both the sides of the reaction.
Answer:
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. Conduction is the transfer of heat between substances that are in direct contact with each other. Thermal energy is transferred from hot places to cold places by convection. Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation.
